the map is at

the href you quoted is the reference in the kml that the placemark should

There is a new www.OpenGastroMap.org

Shows resraurants concerning smoking=yes/no

By editor you can add tag "smoking" in z=18

This is a cooperation with Wikimedia-Toolserver.
Aim is to build a tool for making special maps.
https://jira.toolserver.org/browse/ACCAPP-186
OpenGastroMap is a prototype.

Message-ID: <2139240857.71164.1277967940726.JavaMail.open-xchange@oxltgw04.schlund.de>

Hi guys,

sorry for cross-posting.

I am using a geoserver(2.0.1) as a wfs-service with a postgresql
database and openlayers to show the data.

There is a possibility for the user to search data
within this openlayers application. I am using the
entered searchstring to form a getfeature request.

I am using the filter-function for this:

<ogc:propertyislike wildCard="*" singleChar="." escape="!">
<ogc:propertyname>institutio</ogc:propertyname>
<ogc:literal>*geographie*</ogc:literal>
</ogc:propertyislike>

The problem is that when a user enters a string which is differs only
a tiny bit to the string in the database (case sensitive), the
entry cannot be found. For example: gEoGrApHiE, geographie, GEOGRAPHIE,
Geographie.

Can someone help me to create a case insensitiv application using
openlayers, geoserver and postgresql.

I already found the "matchCase"-option in openlayers, but this
can only be used for EQUAL_TO filters which is not of any help
for me.

IMHP
reprojecting the map is better than reprojecting each feature every time you
switch beetween layers.
so in my project i set map options to
       projection: new OpenLayers.Projection("EPSG:900913"),
       displayProjection: new OpenLayers.Projection("EPSG:4326"),
       maxResolution: "auto",
       maxExtent: new
OpenLayers.Bounds(-20037508.34,-20037508.34,20037508.34,20037508.34),

and then add
         gmap = new OpenLayers.Layer.Google("Google Terrain",{ type:
G_PHYSICAL_MAP, sphericalMercator:true});
         bing = new OpenLayers.Layer.VirtualEarth("Aerial", { type:
VEMapStyle.Aerial, sphericalMercator:true});
         vector = new OpenLayers.Layer.Vector("vectors");

more info on reprojecting and spherical marcator at
http://docs.openlayers.org/library/spherical_mercator.html

but i'm using ol since a month so may be i'm wrong!!

Also, you need to make sure that the JavaScript file is saved in UTF-8 encoding, and that your web server delivers the script with a content-type header that includes the charset.

Hi,

 I am using jquery tabs and openlayers. In Firefox, the map is not loaded
and in IE the map is loaded properly. It is showing centerpx is null or size
is null, javascript errors. 

If i remove the jquery libraries, the map is loaded properly in firefox.

Can anyone tell me, how to solve this conflict between jquery and openlayers
or firefox.

Browse http://www.ifpindia.org/jquerytest and click Map search, to view the
problem 

 Thanks,

Hello everyone,

I'm beginning 
their studies and subsequently the development of an application
integration OL +
GeoServer + PostGIS + PgRouting. If possible I
indicate some 
study materials, links on the subject.
I already have a 
TCC - "Prototype of a System of Urban integrating Routing
PostgreSQL and 
Geoserver - Mauricio Reckziegel "

Topics that will 
be working:
- Integration with PgRouting
- The shortest 
path algorithm
- Cache in GeoServer
- Calculation of average distance and time
- From Route 
search filters
- Styles for the portion of the route
- Route 
Recalculation

I appreciate everyone's attention.
Grateful
Diego Roberto

Subject: [OpenLayers-Users] problem in change bgcolor of layer switcher
Message-ID: <AANLkTilWDD9Mibd4ABxTJHjUvAcEojlSmroczEXb62vL@mail.gmail.com>

Hi list,

I`m trying to change the colors of open layers api according to my
webpage theme. Now I`m trying to change the background color of layer
switcher. I have changed the color inside the css class like this :

.olControlLayerSwitcher .layersDiv {
    padding-top: 5px;
    padding-left: 10px;
    padding-bottom: 5px;
    padding-right: 75px;
    /*background-color: darkblue; ORIGNAL */
    background-color: #556775; /*modified by Imran*/ <--------- CHANGED
    width: 100%;
    height: 100%;
}

but the problem is that there are dark blue bars on top and bottom of
the layer switcher. On examining the div through FireBug it seems
there are spans that do not have a class but some how there color is
being set to dark blue! Any idea what can be done about this?

regards,
Imran

For routing purpose you need to understand Dijkstra's_algorithm

http://en.wikipedia.org/wiki/Dijkstra's_algorithm.

As far as I remember postGIS databases do provide this functionality
given the road network data does not have any topological errors.

Going directly to your map:
   http://www.ifpindia.org/herbarium/index.php?q=search#mapsearch
it works. Clicking the "Map Search" tab from the link you provide
below does not. So I wonder if it is an initialization problem rather
than a jQuery-OpenLayers conflict.

I use jQuery + OpenLayers in my applications without problems, but I
am not using the jQuery tabs.

You just need to &lt; &gt; encode properly and consistently and not have any

Hi Iswaria,

Have you seen this thread:
http://openlayers.org/pipermail/users/2010-January/015956.html

If this is of no help, you could try not to use the jquery $() but the 
jquery noConflict instead.
Regards,
Christoph

Subject: [OpenLayers-Users] Change Layers,
	but Layer does not show until zoom out/in performed
Message-ID: <4C2CB0D7.7030406@swoodbridge.com>

Hi Chris,

Thank you for your feedback on changing layers. I got almost everything 
working. I think I ran into the remaining issue a long time ago, but I 
can not for the life of me find the old post or solution. And this might 
not be exactly the same problem.

I have three base layers:

1. Tiger in EPSG:4326
2. Google in EPSG:900913
3. Streets in EPSG:4326

and a couple of vector overlays that are always on.

Everything works fine when I switch between any of the base layers 
EXCEPT when I change from Google to Streets.

When I change from Google to Streets nothing is drawn in the view port. 
No mapserver image, no vector data, just the map controls. If I zoom in 
or out everything displays properly.

There are no broken images, not javascript errors reported.
The NET panel shows that the image is requested and received.
In FF console:

map.baseLayer.redraw()

returns true but nothing is displayed.

Here is the app currently under development:
http://imaptools.com:8080/routeloops/index4.php?zoom=11&lat=42.64057&lon=-71.36395&layers=B00TT&ll=-71.389033%2042.619456&len=10&rs=0.13877378737528812&av=1100%2C1200&u=E&cw=1#

To reproduce the issue:

1. open the layerswitcher
2. select Google Map (click through alerts)
3. select Streets (click through alerts) - nothing displays
4. zoom in or out - everything displays ok

Any pointers would be appreciated.

Thanks,
   -Steve

It looks like changing from Google to Tiger also fails to draw. I 
thought I had tried this before and it was working. But I guess it makes 
some sense for consistency sake, but Tiger and Streets are virtually 
identical definitions.

thanks rossko, that worked. now this poses a problem of the batchgeo.com
localizing tool that automatically adds this tags into the kml file. any
other method at hand to do georeferencing of adresses? but I guess this is
antoher forum.
hope that I may help as well.. bernd

OK, digging into this problem more I have found out why it is not 
displayed and how to hack it to cause it to display, but clearly I have 
no idea what I might be doing to cause this.

When I switch from Google to one of the EPSG:4326 layers there are bad 
values for:

map.layerContainerDiv.style.left
map.layerContainerDiv.style.top

When I catch the baseLayer changed event I added:

if (map.baseLayer.name != 'Google Map') {
     map.layerContainerDiv.style.left = "0px";
     map.layerContainerDiv.style.top  = "0px";
}

And this seems to fix the display problem. I'm sure this is not the 
intended way to fix this problem and I'm guessing that I am probably 
using part of the API in the wrong way. But I have not found who or what 
changes those values or why I'm getting numbers like -3e+10

Thanks,
   -Steve

Thank you very much!! =)

Nice solution! I managed to do it this way:


function gup(name){
    name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
    var regexS = "[\\?&]"+name+"=([^&#]*)";
    var regex = new RegExp( regexS );
    var results = regex.exec( window.location.href );
    if( results == null ){
        return "";
    }else {
        return results[1];
    }
}

var cliID = gup("cli");

function setNewCenter(event){
    var fGotten = pdv_nuevo.features[0].geometry;
    map.setCenter(new OpenLayers.LonLat(fGotten.x, fGotten.y), 10,
false,true);
}

pdv_nuevo = new OpenLayers.Layer.Vector("WFS", {
    strategies: [new OpenLayers.Strategy.BBOX(), saveStrategy],
    protocol: new OpenLayers.Protocol.WFS({
        version: "1.1.0",
        srsName: "EPSG:4326",
        url: "http://server:8080/geoserver/wfs",
        featureType: "clientes",
        outputFormat: "json",
        readFormat: new OpenLayers.Format.GeoJSON(),
        schema:
"http://server:8080/geoserver/wfs/DescribeFeatureType?version=1.1.0&typename=asdf:abcde",
        featureNS: "http://server:8080/geoserver/wfs",
        featurePrefix: "asdf"
    })
});
pdv_nuevo.events.register("loadend", this, setNewCenter);

Message-ID: <678304.46720.qm@web46201.mail.sp1.yahoo.com>

Hello,

I have a polyline which I?have stored in an OpenLayers.Layer.Vector layer.? I 
can view this in the web interface with no problems.

I would like to enquire if it is possible to get a length for this line.? What 
would be the code for?this.? To date I have been unable to find a method for 
doing this.?

I know you can measure lines but this would be cumbersome and the results would 
not be accurate enough for my application

Regards

There are 2 functions: getLength and getGeodesicLength.

eg.
var length = vectorFeature.getGeodesicLength(new
OpenLayers.Projection("EPSG:900913"));
where vectorFeature references the polyline on the vector layer you want to
measure.

Hi all,

In this link http://openlayers.org/dev/examples/custom-control.html, the
rectangle we draw by pressing the shift key disappears, as soon as we
complete drawing the rectangle. 

I want to display the rectangle, what user has drawn.

What should be done to display the rectangle.

Thanks,

It seems to me like the box handler returns a set of pixels describing 
the box, and that the code added gets the coordinates for this.

I guess a simlpe approach is the use the coordinates  and construct a 
polygon geometry and then add this as a feature to a vector layer on the 
map, and then apply a style to make it look like the box.

It seems to me like the box handler returns a set of pixels describing 
the box, and that the code added gets the coordinates for this. 
  
I guess a simlpe approach is the use the coordinates&nbsp; and construct a 
polygon geometry and then add this as a feature to a vector layer on the 
map, and then apply a style to make it look like the box.

Subject: [OpenLayers-Users] Remove rectangle from the map
Message-ID: <1278065598212-5247142.post@n2.nabble.com>


Hi,

I have written the script to draw the rectangle. This is the link of my
code: http://pastebin.com/HNyT9CJF

But I want to remove the rectangle, (if any) before drawing the rectangle.

As of now, I can draw any number of rectangles over the map. But My
requirement is to draw only one rectangle and remove the rectangle drawn if
any before.

How to do it?

Thanks.

Subject: [OpenLayers-Users] Loading a map into a hidden div in Safari
Message-ID: <AANLkTilIjVWST-ZIaVHNypb-qoZmomTPQnBx_DmdmT6L@mail.gmail.com>

Hi,

I have a page where a user can select some diferent items, and when an item
is selected, a div with a map is displayed showing where the item is..
The div that contains the map is:

<div id='pop' style="display:none">
        <div id="map" ></div>
    </div>

and the map css is:

#map
{
    height:100%;
    width:100%;
    position:absolute;
    top:0px;
    bottom:0px;
    left:0px;
    right:0px;
    cursor:pointer;
}

If I show the div with jQuery like this:
<input id="Button2" type="button" value="pop!!"
onclick="$('#pop').show(250);"/>

In FireFox, IE and Chrome everuthing goes ok.. But if I try to do with
Safari, the map is not shown..

Is there any problem with this?

Thanks!

Hi,

Use the property 'visibility' of the layer

var Msg = "";
for(var i=0;i<map.layers.length;i++)
{    Msg += map.layers[i].name + " :: " + map.layers[i].visibility + "\r\n";
}
alert(Msg);

Subject: [OpenLayers-Users] Getting Started with TMS
Message-ID: <AANLkTilH5etmhp4rob-h9VGrw9N86hLJ4eZzidgfq4lO@mail.gmail.com>

Hi List,

New OpenLayers user here, so please bear with me. I've searched and spent
many hours but am still stuck. I'm using the 2.9 release.

I have a set of image tiles in z/x/y directory format, i.e.root/7/0/0.png
and so on. I'm using gdal2tiles.py to take a png image of size 18432x18432
px to turn it into 8 zoom levels (0-7). Level 7 has 72 256x256 px tiles as
expected. I just want a flat pixel by pixel projection. I have the files sat
in an accessible web server i.e. no tilecache or mapserver etc, just plain
GET /0/0/0.png

My script is very simple and is copied from the TMS example (that is the
right one to use rather than ZYX etc?) plus the HTML is from the TMS
example:


map = new OpenLayers.Map( 'map', { controls: [], maxResolution: 18432/256,
maxExtent: new OpenLayers.Bounds( 0, 0, 18432, 18432 ), numZoomLevels:8, }
); layer = new OpenLayers.Layer.TMS( "TMS", "
http://192.168.10.1/simpletest1/",
{serviceVersion: '.', layername: '.', type:'png'} ); map.addLayer(layer);

map.addControl(new OpenLayers.Control.MousePosition()); map.addControl(new
OpenLayers.Control.MouseDefaults()); map.addControl(new
OpenLayers.Control.KeyboardDefaults());

if (!map.getCenter())
map.zoomToMaxExtent();


Problem 1:

My projected coordinates seem incorrect, in that I move the mouse around and
see my tiles correctly but not to the right transformation. The bottom left
corner is 0,0, but the top right corner is just reading as 10368x10368. I
was expecting 18432x18432? I have set up the maxExtent incorrectly?

Note: I did try to use a set of manual resolutions too:

resolutions: [ 1, 0.5, 0.25, 0.125, 0.0625, 0.03125, 0.015625, 0.0078125]

..but I get other issues, i.e. something like -80, 80?


Problem 2:

The code about asks for many extra tiles from about zoom level 2 onwards,
i.e. An extra set of tiles above and to the right. Level 3 asks for a row of
3 extra, level 4 for 7 extra and so on. I expect this is related to (1)


I'd appreciate any help. Apologies if it's something stupid.

PS Thanks for OpenLayers - loving it...

I'm making some progress.. but nothing appens

I downloaded proj4js and added these references:
    <script src="OpenLayers-2.8/proj4js/lib/proj4js-compressed.js"></script>
    <SCRIPT type="text/javascript"
src="OpenLayers-2.8/proj4js/lib/projCode/tmerc.js"></SCRIPT>
    <SCRIPT type="text/javascript"

    <SCRIPT type="text/javascript"

    <SCRIPT type="text/javascript"
src="OpenLayers-2.8/proj4js/lib/defs/EPSG900913.js"></SCRIPT>

I created the file the EPSG3003.js

Proj4js.defs["EPSG:3003"] = "+proj=tmerc +lat_0=0 +lon_0=9 +k=0.9996+x_0=0
+y_0=0 +ellps=intl +a=6378388.0 +rf=297.0000000000601+units=m +no_defs";

but the google satellite map is not beeing reprojected...

Subject: [OpenLayers-Users] Custom EditingToolbar displays the wrong button
	icon
Message-ID: <4C31CFBD.6090306@romtelecom.ro>

Hello everyone,

Long time no see :)

I want to add a "save" button to my editingToolbar (which was 
customized) in order to manually save changes. I am using the following 
code:

   //overload the EditingToolbar initialize function:
     OpenLayers.Control.EditingToolbar.prototype.initialize = 
function(layer, options){
             OpenLayers.Control.Panel.prototype.initialize.apply(this, 
[options]);

         this.addControls(
           [ new OpenLayers.Control.Navigation() ]
         );
         var controls = [
           new OpenLayers.Control.DrawFeature(layer, 
OpenLayers.Handler.Point, {'displayClass': 'olControlDrawFeaturePoint'}),
           new OpenLayers.Control.Button({ title: "Save changes",
                                                   trigger: function() {
                                                       saveStrategy.save();
                                                   },
                                                   displayClass: 
"olControlSaveFeatures"
                                                   })
         ];
         this.addControls(controls);

     };
     editingToolbar = new OpenLayers.Control.EditingToolbar( 
editableLayer ) ;
     map.addControl( editingToolbar );

Everything works as expected, but there is only one problem. In the 
toolbar I get instead of the "save_features_off.png" icon the "move" 
icon.  Playing with firebug I can see that the active CSS for the 
toolbar (.olControlEditingToolbar) overrides 
".olControlSaveFeaturesItemInactive" and overrides the image. If I 
disable the background-image statement from .olControlEditingToolbar I 
can see the save icon. Most likely the move icon is on top of the save 
icon...

Any ideas on how to fix this - even as a hack?

Thanks.

I attached some small screenshots to illustrate this.

Regards,
Adrian

Subject: [OpenLayers-Users] Style context as an object ?
Message-ID: <20100705154150.GC26151@keybit.net>

Did anyone ever tried using a "proper" object
as a Style context ?

What I'm trying to do is create a class of style
contexts and pass instances of them (for parametrized
styles) as a Style.context, but 'this', within the
callbacks, seem to always evaluate to the top of DOM.

Example code:

  MyContextClass = function(radius) {
  	this.radius = radius;
  };
  
  MyContextClass.prototype.getRadius() {
  	alert(this.radius);
  };
  
  myContext = new MyContextClass(4);
  
  myStyle = OpenLayers.Style(
  	{ pointRadius: '${getRadius)' },
  	{ context: myContext }
  );

As far as I know, you can reproject your vector features on the fly (say 
from 3003 to 900913) but you cannot
reproject imagery of any sort on the fly. If you use google imagery, you 
are stuck with getting everything else
into that projection.

Message-ID: <AANLkTimVFl-_RQXSzCVrip8td18mTAKjZ9x_ozHq8r21@mail.gmail.com>

Hi Group,

There are few security concerns at my organization and due to that, I can
not directly access openlayers.org for OpenLayers.js. So, I installed it and
changed my script as below

<script src=*'D:\OpenLayers-2.9.1\OpenLayers.js'*></script>
 </head>
 <body>
  <div id='map'></div>
  <script type="text/javascript">
   //var map = new OpenLayers.Map('map',{maxResolution: 1000} );
   var map = new OpenLayers.Map('map', {
      maxExtent: new OpenLayers.Bounds(
-638480920.244,-188017611.367,665489491.580,1019789790.73),
      maxResolution: 5000
      } );
   var wmscURL = [
    "
http://siasporapv01:8080/gss/ogc?version=1.3.0&crs=sw:nsw_trans_mercator_mm&styles=Default
"
    ];
   var myLayer = new OpenLayers.Layer.WMS( 'Cambridge Steet' , wmscURL , {
layers: 'background' ,  format: 'image/png'} , { buffer: 1 , isBaseLayer:
true } );
   map.addLayer( myLayer )
   map.zoomToMaxExtent();
  </script>

Now the problem is that, It's not showing any controls on the map and also
not sending any requests to my server. Everything comes out with no image
tiles.
If I use openlayers.org/api/openlayers.js on my local machine it works
perfect.

Am I missing something ? Is is not the way to configure OpenLayers ?

Thanks,
Kalyan

Hi Robert,

Thanks for the reply. I just placed my html file in the openLayers folder
and it came out with the default zoom and pan controls on the map. But, the
real problem is that, it's not sending any WMS requests to my Web server. I
wonder, I may have done something wrong. But, couldn't find it.

It worked when I used the openlayers.org/api/openlayers.js reference.But,
now I can not use it as my network is under security control.

But, it should normally be okay when I reference to the local openlayers.js
right ? Any suggestions ??

Thanks,
Kalyan

Another problem with the configuration,

I got heaps of the following xml files in my OGC resources folder

<ServiceExceptionReport xmlns="*http://www.opengis.net/ogc*" xmlns:xlink="*
http://www.w3.org/1999/xlink*" xmlns:xsi="*
http://www.w3.org/2001/XMLSchema-instance*" version="*1.3.0*"xsi:schemaLocation

 * * <ServiceException code="*InvalidParameterValue*" locator="*
application/vnd.ogc.se_inimage*">*Validation failed for parameter
[exception], value [application/vnd.ogc.se_inimage].*</ServiceException>
 * * </ServiceExceptionReport>

Is that because I have no access to www.opengis.net ? I have no access no
any of the above pages. Is this the reason for all my problems ?

Robert,

Yes. I did get images with WMS service from my server. I have JBOSS running
on my machine as a web server. I'll place my html and openlayers.jc in
htdocs and give it a go.

Local html sending ajax to remote wms server is the security issue I 
believe. Put a webserver on your machine, set up the proxy, access it 
from there.

	Parameter
Message-ID: <AANLkTinPyMHo32XhG2hK4l28RRcPoiFlGbWnfPIoMf5o@mail.gmail.com>

Hello Group,

I am facing a validation problem with one of the parameters openlayers try
to request along with WMS request.

<ServiceException code="*InvalidParameterValue*" locator="*
application/vnd.ogc.se_inimage*">*Validation failed for parameter
[exception], value [application/vnd.ogc.se_inimage].*</ServiceException>

I am getting the image/map response when I use the same URL at browser and
getting the above problem when I embed that in openlayers request. Does the
open layer include this exception parameter with every WMS request. If so,
How to stop it from sending that parameter ?

Regards,
Kalyan

   map.addLayer( myLayer );
   map.zoomToMaxExtent();
  </script>


It should actually send only one WMS request for the first time and then act
according to uses operations like Pan , Zoom. But, that is not how it's
working. Everytime when I open this html file, it's sending 48 WMS requests
and creating 48 image files in the resources folder and none of these images
are turned up on the browser. Also, surprisingly all those 48 images are
empty with just white background.

Does any one what the problem is ?

Thanks,
Kalyan

Hi,

use singleTile: true and ratio: 1 in your layer options.

I Solved it.

It's the problem with resolution. I changed the resolution from 1000 to
8000000 and that solved my problem. Is there a start/begin document for Open
Layers ? other than that example developments ??

Any ideas?
I thought of changing the icon for the button (as a hack), but the 
trouble is - I need to add two buttons and both of them display the same 
icon - so I can't use that approach.

Is there another way I can build my toolbar and specify what items to 
show? Any existing examples?

Update - I've upgraded from OpenLayers 2.8 to 2.9.1 and the issue is 
fixed. :)

The toolbar looks fine now. Should have tried to update sooner...

Hello group,

I have a WMS base map on OpenLayers and I want to use my web servers select
web service to know the feature information or get notified of the selected
feature. How do I get notified when the user select or click on the map ? Is
there any default select notifiers/listeners available in OpenLayers ? I
also want to mark that place with a 'X' or some kind of representation. Is
there any such default services or little configurable services available ?

Well, I ran into the same problem while adding a custom button (revert 
changes).
Here's my code:

//overload the EditingToolbar initialize function:
     OpenLayers.Control.EditingToolbar.prototype.initialize = 
function(layer, options){
             OpenLayers.Control.Panel.prototype.initialize.apply(this, 
[options]);

         this.addControls(
           [ new OpenLayers.Control.Navigation() ]
         );
         var controls = [
           new OpenLayers.Control.DrawFeature(layer, 
OpenLayers.Handler.Point, {'displayClass': 'olControlDrawFeaturePoint'}),
           new OpenLayers.Control.Button({ title: "Save changes",
                                                   trigger: function() {
                                                       saveStrategy.save();
                                                       //after saving 
clear the dynamic items displayed
                                                       
layer.destroyFeatures();
                                                   },
                                                   displayClass: 
"olControlSaveFeatures"
                                                   }),
           new OpenLayers.Control.Button({ title: "Revert changes",
                                                   trigger: function() {
                                                       
layer.destroyFeatures();
                                                   },
                                                   displayClass: 
"revertButton"       // show a custom icon
                                                   }),
         ];
         this.addControls(controls);

     };
     editingToolbar = new OpenLayers.Control.EditingToolbar( 
editableLayer ) ;
     map.addControl( editingToolbar );

This is the CSS that is loaded in the map:

div.revertButtonItemInactive {
          background-image:url("symbols/revert.png");
         background-position:0 1px;
         background-repeat:no-repeat;
      }
      div.revertButtonItemActive {
          background-image:url("symbols/revert.png");
         background-position:0 1px;
         background-repeat:no-repeat;
      }

When I inspect with firebug I can see that my icon is overriden by the 
EditingToolbar:
.olControlEditingToolbar div {
     background-image:url("img/editing_tool_bar.png");
     background-repeat:no-repeat;
     float:right;
     height:24px;
     margin:5px;
     width:24px;
}
div.revertButtonItemInactive {
     background-image:url("symbols/revert.png");  //striken in firebug
     background-position:0 1px;
     background-repeat:no-repeat;  //striken in firebug
}

For a similar save button (which comes bundled in OL), the difference is 
that the order of the two CSS sections is reversed.

How can I reverse them back/fix this issue?

Adrian

Subject: [OpenLayers-Users] Getting server output when using save strategy
Message-ID: <4C331F53.6050303@romtelecom.ro>

Hello everyone,

I'm trying to create a callback function for the save strategy so that I 
can display a status message for the user in case there are problems 
with saving their changes (e.g. - session expired, etc).
I want the serverside script to send back a JSON formatted string that 
would describe what the problem was - for instance: 
({'failure':true,'error':'You do not have rights to make changes'}). I 
indend to eval this message and extract the error and show it to the user.

I have created a trigger that fires on "success", but I can't find 
anywhere the response from the server (so that I can parse it):

var saveStrategy = new OpenLayers.Strategy.Save();
saveStrategy.events.on({'success': function(event){
        alert("On save success");
}});

The event parameter that gets passed to the function has a 
"Strategy.Save" object and a "Protocol.Response" object. By browsing 
both of them I still couldn't find the original message returned by the 
server.

By the way, the server returns content-type text/html.

I noticed that the failure event is triggered when the server returns a 
500 error, but I wouldn't want to have to crash my server-side script on 
purpose in order to catch a problem on the client-side.

Am I missing something or doing something wrong?

Thanks,
Adrian

Subject: [OpenLayers-Users] hardcoded gml:featureMemeber of WFS layer in
	openlayers ?
Message-ID: <4C332392.1050803@ksat.no>

hi everyone,

I have a problem adding a WFS request as overlay on the openlayers map.
Is there a way to tell it to search for other featureProperty elements 
then the basic "gml:featureMember" ?
Is it realy hard-coded into the parser source that the featureProperty 
name shall be "gml:featureMember" ?

The WFS service is set up with a GML Application Profile which defines 
its "FeaturePropertyType" as a restriction of the generic 
gml:FeaturePropertyType (and similar for the FeatureCollectionType).
This means that the structure of the GML returned from the WFS request is:

<wfsos:featureCollection 
xmlns:wfsos="http://cweb.ksat.no/cweb/schema/geoweb/oil" ... 
schemaLocation="http://cweb.ksat.no/cweb/schema/geoweb/oil ...>
    <wfsos:featureMember>
        <wfsos:feature>
            <wfsos:oilSpill>
                <gml:Polygon srsName="EPSG:4326"> ........

It seems that the featureCollection level is ignored (as well as the 
schema location - since the schema is not loaded), so that one is not 
the problem.
I can set the name space prefix, and element name for the "feature" 
level and the geometry, but can't find any way to do this for the 
featureMember level!

If I run this from a file, and change the wfsos:featureMember into 
gml:featureMember it works fine (even if it violates the schema).

To repeat the question: Is there any way to instruct openlayers to look 
for wfsos:featureMember instead ?

PS:
Here is the code for the WFS request linkage:

             wfs_ksat = new OpenLayers.Layer.Vector(id, {
                     strategies: [new OpenLayers.Strategy.BBOX()],
                     projection: new OpenLayers.Projection("EPSG:4326"),
                     protocol: new OpenLayers.Protocol.WFS.v1_0_0({
                         url: ksatWFSuri,
                         featureType: "feature",

Ok, thanks, now I manage in overlapping layers, but I still have a little
accurance problem: it seems that there are around 20 meters of distance
between the same point in google and in my maps.

Hi,

basically this requires writing your own format, which can extend
OpenLayers.Format.GML.v3.

OpenLayers only supports the GML 3.1.1 Simple Features profile out of the
box:

http://schemas.opengis.net/gml/3.1.1/profiles/gmlsfProfile/1.0.0/gmlsf.xsd

It should not be too hard to write the format. Make sure you add wfsos to
the namespaces array and add a reader function where necessary.

Btw, in your code below you are using the old GML parser.

Best regards,
Bart

You're probably missing some params in the epsg definition of 3003. it
should look like this:

+proj=tmerc +lat_0=0 +lon_0=9 +k=0.999600 +x_0=1500000 +y_0=0
+ellps=intl +units=m +no_defs
+towgs84=-104.1,-49.1,-9.9,0.971,-2.917,0.714,-11.68 +to +proj=latlong
+datum=WGS84

the important bits are +towgs84=-104.1,-49.1,-9.9,0.971,-2.917,0.714,-11.68

Cheers,
Umberto

Subject: [OpenLayers-Users] Load GML layer from text field?
Message-ID: <1278420936039-5260132.post@n2.nabble.com>


Hi!
I want to show a GML polygon that I get from a web service on the map. All
the examples of showing GML makes me load an XML file as in the
gml-layer.html example:

map.addLayer(new OpenLayers.Layer.GML("GML", "gml/polygon.xml"));

I don't know how to load GML on the fly without a prepared file. Is it
possible to draw a GML string I put in a hidden text field or a hidden div
on the page instead?

Thanks!

Adrian,

Try something like this:

var saveStrategy = new OpenLayers.Strategy.Save({
? onCommit: function(response){
??? if(response.success()) {
????? alert(response.priv.responseText);
??? }
? }
});

To: users <Users@openlayers.org>
Message-ID: <4C331F53.6050303@romtelecom.ro>
Content-Type: text/plain; charset=UTF-8; format=flowed

Hello everyone,

I'm trying to create a callback function for the save strategy so that I 
can display a status message for the user in case there are problems 
with saving their changes (e.g. - session expired, etc).
I want the serverside script to send back a JSON formatted string that 
would describe what the problem was - for instance: 
({'failure':true,'error':'You do not have rights to make changes'}). I 
indend to eval this message and extract the error and show it to the user.

I have created a trigger that fires on "success", but I can't find 
anywhere the response from the server (so that I can parse it):

var saveStrategy = new OpenLayers.Strategy.Save();
saveStrategy.events.on({'success': function(event){
? ? ? ? alert("On save success");
}});

The event parameter that gets passed to the function has a 
"Strategy.Save" object and a "Protocol.Response" object. By browsing 
both of them I still couldn't find the original message returned by the 
server.

By the way, the server returns content-type text/html.

I noticed that the failure event is triggered when the server returns a 
500 error, but I wouldn't want to have to crash my server-side script on 
purpose in order to catch a problem on the client-side.

Am I missing something or doing something wrong?

Thanks,
Adrian

Message-ID: <4C346811.5030302@fh-bingen.de>

  Hi list,

i am focussing a heavy bug being a hard showstopper in my project.
Problem:
We have developed a so called GeoEditor. It works fine if we stay in 
EPSG:31467.
Now we switched to EPSG:900913 in order to be able to use GoogleMaps
EPSG:900913 is our internalProjection, whereas data is saved in the 
backend as EPSG:31467.
There are nearly no problems while joining, splitting and creating 
multipolygons.
The trouble starts, whenever we modify a feature using a 
ModifyFeatureControl.
After removing or moving a point data is send to the server in 
EPSG:31467 declared as EPSG:900913.
Data is send via WFS-T to our GeoServer-Backend.

Any suggestions where my problems come from?

TIA
Carsten

Thank you Gabriel,

I tried your suggestion, but I get an error saying that response.priv is 
null (and it exists, but is null when looking in firebug).
Do I need to add something to the layer definition in order for this to 
work?

Subject: [OpenLayers-Users] Can't restrict Openlayers.Layer.OSM to use
	specific zoom levels
Message-ID: <4C3476C1.1070501@romtelecom.ro>

Hello,

I have a map that uses just 12 zoom levels by defining numZoomLevels: 12 
and an array of allowed resolutions. All base layers (Google, Yahoo and 
Mapserver) have a similar configuration (e.g. for Google: 
MIN_ZOOM_LEVEL: 7, MAX_ZOOM_LEVEL:19, RESOLUTIONS: res) and work as 
expected.

However, the OSM layer allows me to zoom beyond these resolutions if I 
define it like this:

var osm = new OpenLayers.Layer.OSM.Osmarender('OpenStreetMaps', 
{numZoomLevels: 12, minZoomLevel: 7, maxZoomLevel: 19});

If I add the resolutions parameter something interesting happens: the 
zoom is restricted, but I loose the tiles, because they can no longer be 
found (404 errors):
var osm = new OpenLayers.Layer.OSM.Osmarender('OpenStreetMaps', 
{numZoomLevels: 12, minZoomLevel: 7, maxZoomLevel: 19, resolutions: res});
My "res" array is: var res = [2445.9849046875, 1222.99245234375, 
611.496226171875, 305.7481130859375, 152.87405654296876, 
76.43702827148438, 38.21851413574219, 19.109257067871095, 
9.554628533935547, 4.777314266967774, 2.388657133483887, 
1.1943285667419434, 0.597164283];

The tiles requested have the following URLs: "NetworkError: 404 Not 
Found - http://a.tah.openstreetmap.org/Tiles/tile/1/76/42.png" (this is 
for a zoom level 1, which coresponds to a normal zoom level of 7 (I think))

My question is - is this a bug, or is there a way to instruct the layer 
to "adjust" the value of zoom by a constant (6+x)?

I've looked over the OpenLayers.Layer.OSM definition, and I should be 
able to adjust the url attribute, but I have no idea how to force it to 
do an addition, or if this is the right way to go:

OpenLayers.Layer.OSM = OpenLayers.Class(OpenLayers.Layer.XYZ, {
      name: "OpenStreetMap",
      attribution: "Data CC-By-SA by <a 
href='http://openstreetmap.org/'>OpenStreetMap</a>",
      sphericalMercator: true,
      url: 'http://tile.openstreetmap.org/${z}/${x}/${y}.png',
      CLASS_NAME: "OpenLayers.Layer.OSM"
});

Regards,
Adrian

There is no way to do this with the current OSM layer.

Hello,

I loaded several KML-Files into Openlayers and they are all showing
Anchorbubbles with the info. (this is working greate).

Now I want to add a control, where I can select a layer and only the
selected layer is showing the Anchorbubble. I do n not know where to go now
further. Any help would be nice.

Regards

Subject: [OpenLayers-Users] KML doesn't display from Http response
Message-ID: <20100707164810.0ddf066a@garfield>

Hi,

I've got a problem when loading a KML file. If I use an existing file
in my webapp, the layer appears correctly, but if I use a Servlet
returning a Kml as response, it doesn't work.

Here is the KML initialization where title and url are parameters of
initialize method put onLoad of the page : 

var kml = new OpenLayers.Layer.GML(title, url, {
            format: OpenLayers.Format.KML,
            formatOptions: {
                extractStyles: true,
                extractAttributes: true
            }
    });

In firebug, there is those results. The both contents are the same KML
file. The KML is valid and generated using JavaApiForKml [1]


KML file ------------------------------------------------

url = "temp.kml"

The request is the same

I have the same result with content-type = application/xml

-------------------------------------------------------------

I use OpenLayers with Apache Tapestry [2] Java Framework. I have a
simple page that returns a StreamResponse with content-type as
specified above.

If it's not possible, do you have any tips to display the KML without
creating explicitely the file on server or how to create it easily
directly in webapp and remove the file in javascript ?

Thanks for your help

Its a KMZ - zipped - file.  OpenLayers can't unzip files in javascript.
Try it as a KML.

Hi,

I have a map and some vector and markers layer on it.

When I resize the map for expand or collapse like in Google maps.Although 
my vector layers elments like point,line are correctly relocating.
but my markers layers markers couldn't.
 
when resizing the map  I am calling map.updateSize()  function when I look 
the code this function calls every layers onMapResize function and I think 
markers layer is not implementing this function.

Any idea to solve this.

Best Regards,
Tamer

Hi,

your analysis is right. 2 options to solve it:

1) create a patch to add onMapResize to the Marker layer
2) use a Vector layer with an externalGraphic, will look the same as your marker layer, but will properly resize.

Best regards,
Bart

Subject: [OpenLayers-Users] OpenLayers.Control.GetFeature with diffrent
	layers (typenames) and different servers
Message-ID: <AAD98904A979004F8FD29D8368C64638420958@SERVER-MAIL.le34.dk>

Hi everybody.

 

I have been using the OpenLayers.Control.WMSGetFeatureInfo with a
drill-down to get featureinfo from diffrent layers on different servers.


The control which worked fine, was configured like this:

 

var control = new OpenLayers.Control.WMSGetFeatureInfo(

{

    url: 'server1',

    layerUrls: ['server2'],

    layers: [Layer1_on_server1, Layer2_on_server1, Layer1_on_server2,
Layer2_on_server2],

    title: 'Get Feature Info',

    queryVisible: true,

    drillDown: true,

    infoFormat: 'application/vnd.ogc.gml',

    eventListeners:

    {

        getfeatureinfo: function(event) { handleGetFeatureInfo(event); }

    }

});

 

 

But one of the services, that I am using, have suddenly stopped
supporting WMS GetFeatureInfo request. So now I have to use their WFS
service to get featureinfo.

 

My question is then can I use the OpenLayers.Control.GetFeature to get
featureinfo from diffrent layers (typenames) and different servers?

 

Below is my code that works with two layers (typenames) on the same
server:

 

var WFScontrol = new OpenLayers.Control.GetFeature({

                             protocol: 

 
OpenLayers.Protocol.WFS({

                                                           readFormat:
new OpenLayers.Format.GML(),

 
formatOptions: {

 
outputFormat: "application/vnd.ogc.gml"

                                                           },

                                                           featureType:
['pdk:theme_pdk_lokalplan_vedtaget_v',
'pdk:theme_pdk_lokalplandelomraade_vedtaget_v'],

                                                           url:
'http://wfs.plansystem.dk/geoserver/wfs?', 

                                                           version:
'1.0.0', 

                                                           geometryName:
['geometri'],

                                                           srsName:
'EPSG:25832'

                             }), 

                             click: true,

                             box: true

});

 

Is it possible to get the GetFeature control to work like the
WMSGetFeatureInfo?

 

Any help or comment would be appreciated.

 

Regards Esben

No sorry this is not possible. Maybe multiple controls will work as a work-around.

The problem comes from Transfer-Encoding chunked. OpenLayers doesn't support
this encoding for KML file... Only a part of the KML is rendered.

It's ok I resolve my problem setting the Content-Length in response with
stream length bytes, so Transfer-Encoding will be not used and Kml layer is
displayed correctly !

You can nest panels using the items property. For example:

var myPanel = new Ext.Panel({
        title: 'Top level',
        layout: 'border',
        items: [{
            xtype:'panel',
            title:'Sub1',
            html:'Contents of sub panel 1',
            region: 'east'
        },{
            xtype:'panel',
            title: 'Sub2',
            html:'Contents of sub panel 2',
            region: 'center'
        }],
        width:300,
        height:200,
        renderTo:'panelDiv'
    });

The layout property on the outer container determines the position of the
items within it. Here, we have set the layout to be a border layout, which
requires that items be given a region property like ?center?, ?north?,
?south?, ?east?, or ?west?.

Subject: [OpenLayers-Users] MergeNewParams / redraw
Message-ID: <1278608673006-5271050.post@n2.nabble.com>


Hi all,

I use:
====
 - Openlayers 2.9.1
 - GeoExt 0.7
 - GeoServer 1.7.7

I want:
=====
... to use a new SLD for my WMS-Layer.
The Layer is inside a LayerTree, a map and inside a Legend-Panel.

Problem:
======
I use the below code to update the SLD. The Legend-Graphic inside the
Legend-Panel accepts the new Style. The map doesn't accept the new style.
There is still the old style for the layer.

Code:
====
node.layer.mergeNewParams(
   {
      format        : "image/png",
      transparent : "true",
      sld_body     : sld
   },
   {
      isBaseLayer              : false,
      unsupportedBrowsers : []
   }
);
node.layer.redraw(true);


I found a lot posts about this topic. But nothings helped. Now, I'm not sure
to use mergeNewParams() the right way. Can I use this Method with
OpenLayers.Layer.WMS? Is there anything else I have to consider?


Thanks

Sascha

Try using styles: instead of sld_body:.

No. sld_body is correct. But accompany it with
styles: ""
in the mergeNewParams object.

Subject: [OpenLayers-Users] Transparent Overlays
Message-ID: <AANLkTinbi-muIOoQGDKqPNXX3l1QggY8Ij4hEeod4JmP@mail.gmail.com>

Hello Group,

I have a base layer and a couple of overlays. The base layer has some
objects to display and both the overlays have nothing to display. But the
total map shows nothing but just a white sceen. I suspect the overlays
hiding the base layer. How do I set these overlays transparent so that I can
see the base layer and on top of that these overlays ?

My WMS layer definitions are as below

var gisLayer = new OpenLayers.Layer.WMS( 'Gis Layer' , wmsURL , { layers:
'gis', styles: 'Default', format: 'image/png' } , { buffer: 1 , isBaseLayer:
false } );
   var adminLayer = new OpenLayers.Layer.WMS( 'Admin Layer' , wmsURL , {
layers: 'admin', styles: 'Default', format: 'image/png' } , { buffer: 1 ,
isBaseLayer: false } );
   var cadLayer = new OpenLayers.Layer.WMS( 'Cadastre Layer' , wmsURL , {
layers: 'cadastre', styles: 'Default', format: 'image/png' } , { buffer: 1 ,
isBaseLayer: true} );

I am sorry, I have a very little knowledge in Java Script and so I keep
posting these little things.

Thanks,
Kalyan

Hi,

after "format: 'image/png'", add ", transparent: true".

That's it.

Regards,
Andreas.

Hi Andreas,

I tried your way.

node.layer.mergeNewParams(
    {
       sld_body  : sld, // sld is a var with the content SLD_BODY (see 
below in the table)
       'styles'      : ""
    }
);

The result is still the same. The Legend gets the new Style. The map not.
These are the Parameters Firebug gaves me, when I perform mergeNewParams().

EXCEPTIONS 	|application/vnd.ogc.se_xml|
FORMAT 	|image/gif|
LAYER 	|WL:Gewaesser|
PROJECTION 	|EPSG:31256|
REQUEST 	|GetLegendGraphic|

TRANSPARENT 	|true|
VERSION 	|1.1.1|


The Request ist 'GetLegendGraphic'. Is this right?

Is there a requirement, that the new Style has to be on the GeoServer?

Regards,
Sascha

Hi Andreas,

I changed the Name of the NamedLayer inside the sld.

<NamedLayer>
<Name>Gewaesser</Name>
  to

<NamedLayer>
<Name>WL:Gewaesser</Name>

Now, it works.

Thanks a lot!

Sascha

Subject: [OpenLayers-Users] RegularPolygon as a search polygon
Message-ID: <001301cb1f57$98372e00$c8a58a00$@com.au>

Guys,

 

I have been able to build a control to freehand digitize a polygon and then
launch a function to use the polygon as a search polygon in a WFS request. 

 

This works for me:

 

drawControls = new OpenLayers.Control.DrawFeature(vectorLayer,
OpenLayers.Handler.Polygon) ;

                // extend the drawcontrol with its behavior

                OpenLayers.Util.extend(drawControls, 

                {              draw: function (){

this.polygon = new OpenLayers.Handler.Polygon(drawControls,{"done":
this.notice});                this.polygon.activate();},

                                notice: function (polygon)

                                {

                                                // get vertices of polygon
into and array of coordinate pairs

                                                var polyString =
polygon.toString() ;

                                                

                                                // do whatever with polygon
linestring here

.                             

                                }

                });              

   map.addControl(drawControls);

 

 

I wanted to use the RegularPolygon feature to do the same but it does not
launch the function in the same way after the vector geometry is
successfully created.  

 

var polyType = 6;

var rad = '';

polyOptions = {sides: polyType, radius: rad, angle: 0}

shapeControl = new OpenLayers.Control.DrawFeature(vectorLayer,
OpenLayers.Handler.RegularPolygon, {handlerOptions: polyOptions});

                // extend the shapeControl with its behavior

                OpenLayers.Util.extend(shapeControl, 

                {              draw: function (){

                                this.polygon = new
OpenLayers.Handler.RegularPolygon(shapeControl, {"done": this.notice});
this.polygon.activate();},

                                notice: function (polygon)

                                {

                                                // get vertices of polygon
into and array of coordinate pairs

                                                var polyString =
polygon.toString() ;

                                                // do whatever with polygon
linestring here

                                                .


                                }

                 });

 

In both cases the polygon is created and drawn to the vectorLayer.

 

Can anyone see anything obviously wrong with the second piece of code?

 

Cheers,

Hi there,

You have a 3 MB javascript file for your map! that's HUGE! And the time to
proccess all that file is pretty much and that's why the browser is warning
you about it. You have to optimize your code somehow..

You should use a different datasource for such amount of information but not
your javascript file..!

Cheers,

Gilberto Ramos

Well, despite I'm not a pro I tell you that you should read more about GIS..
what it means to do, how it works, etc. If you don't have the concepts clear
you will take the very difficult way! So I suggest you to read about GIS
basic until you have a clear panorama.

And answering your question, take a look a this article 
http://www.ibm.com/developerworks/library/ar-gis1/ Building a geospatial
information system, Part 1: Understanding the basics 

hope that helps you,

Gilberto Ramos

You could serve transparent image tiles to overlay on ordinary maps ; so that
all the hard work is done server-side.   For fixed data, like borders, you
can produce the imagery ahead of time once only.   This is what WMS is for
in OpenLayers.

There might well be other problems with your map ... I can't get past the
enormous javascript to find out!

Took three minutes and a "script running slow" prompt in IE ; in Firefox
about the same time and eight prompts.  Not all PCs or browsers are alike.

The javascript file here is "only" 2Mb ... you've got to simplify.  Just
taking out whitespace would help.  Do you really need both google and yahoo
maps? Can you simplify the projections in use?  Would another data format
work quicker than WKT?  Do your points really need to be specified to better
than 1mm precision?

Seperating the data from the script is good practice, and should allow you
to at least show some kind of map while all the crunching is going on,
instead of the nothingness that currently greets visitors to your page.

As others have said you really should be doing the following:

1) Reproject the geometries on the server so that the web browser will not
need to do this for each geometry. Your geometries range from around 10,000
points to nearly 14,000 points.
2) If at all possible run a simplification on the geometries so that you do
not have so many points as that alone is an issue for most web browsers. It
actually made even Google Chrome feel sluggish when dong the hover events.
This can be done in PostgreSQL/PostGIS as well as a slew of desktop software
packages.
3) Try rounding your decimal places to 5 or 6 instead of going to 9, this
will at least help you on your download sizes so that the initial page load
occurs quicker.

Have you considered using the Douglas Peucker point reduction algorithm 
as a way of, well, reducing the number of points?  See

Try downsampling your image and using that for your overview map

1.5gb to a tiny little map is a lot of processing... ie like for say a 5k
image result

you need to precahe your image, you GeoWebCache. Its embeded in
Geoserver if you are using that

Guys,

 

Still need some help on this.

 

I have taken the simple app from examples and edited it to see if I can make
this work. It works but not the way I expect it to work?

 

See : http://staging.demos.numaps.com.au/shape_tester.html

 

I have extended the DrawFeature control to echo out the coordinates of the
vector generated polygon. When the control is deactivated (controlled by the
'navigate' radio) the notice function is triggered - not sure why? 

I am trying to trigger this function only when the control is activated. 

 

Its just not doing what I would have expected so I must be doing something
really stupid. 

 

Can someone have a quick look at this for me?

 

Cheers.

 

Brad..

Subject: [OpenLayers-Users] RegularPolygon as a search polygon

 

Guys,

 

I have been able to build a control to freehand digitize a polygon and then
launch a function to use the polygon as a search polygon in a WFS request. 

 

This works for me:

 

drawControls = new OpenLayers.Control.DrawFeature(vectorLayer,
OpenLayers.Handler.Polygon) ;

                // extend the drawcontrol with its behavior

                OpenLayers.Util.extend(drawControls, 

                {              draw: function (){

this.polygon = new OpenLayers.Handler.Polygon(drawControls,{"done":
this.notice});                this.polygon.activate();},

                                notice: function (polygon)

                                {

                                                // get vertices of polygon
into and array of coordinate pairs

                                                var polyString =
polygon.toString() ;

                                                

                                                // do whatever with polygon
linestring here

.                             

                                }

                });              

   map.addControl(drawControls);

 

 

I wanted to use the RegularPolygon feature to do the same but it does not
launch the function in the same way after the vector geometry is
successfully created.  

 

var polyType = 6;

var rad = '';

polyOptions = {sides: polyType, radius: rad, angle: 0}

shapeControl = new OpenLayers.Control.DrawFeature(vectorLayer,
OpenLayers.Handler.RegularPolygon, {handlerOptions: polyOptions});

                // extend the shapeControl with its behavior

                OpenLayers.Util.extend(shapeControl, 

                {              draw: function (){

                                this.polygon = new
OpenLayers.Handler.RegularPolygon(shapeControl, {"done": this.notice});
this.polygon.activate();},

                                notice: function (polygon)

                                {

                                                // get vertices of polygon
into and array of coordinate pairs

                                                var polyString =
polygon.toString() ;

                                                // do whatever with polygon
linestring here

                                                .


                                }

                 });

 

In both cases the polygon is created and drawn to the vectorLayer.

 

Can anyone see anything obviously wrong with the second piece of code?

 

Cheers,

Message-ID: <AANLkTimsyvPHatvK9trGa6WoieEcE7P0rIUBGDBCZpBh@mail.gmail.com>

Hi,

I confiigured openLayers with WMS services to my server. Unfortunately, the
map caching at my server is not supported with WMS requests and is only
supported with my native map requests. So, I now have to develop/write a
custom function in openlayes that reads my native map response and presents
the map layer on openlayers. I am a novice in Java script and my timelines
are too short. I need you people help to write it.

My native map service response is as shown below

So, how difficult it is to write a custom function ( just like the WMS one )
that automatically sends the pan, zoom requests to my server.

Hi,

I managed to write a custom class that sends the native map requests to my
server.But, the problem is, the response I get from my server is in XML
format and I wanted to show the actual image files on the map. Could some
one tell me where to get handle of  map service reposne please ? so that I
can parse XML response and display images.

You can find the XML reponse down this mail .

Thanks,
Kalyan

Hi,

I`m trying to assign a custom mouse cursor to a styleMap.

this is how im trying to do it

var highlighted = new OpenLayers.Style({
																		  'strokeWidth': 1,
  																		'strokeColor': '#ff0000',
  																		'fillColor': '#ff0000',
  																		'fillOpacity':0.4,
  																		'cursor': 'url('openlayers/theme/default/img/pan.gif')'
  																		
																		}); // style for vector layer to be highlighted


but the cursor wont change, although it works for default built in cursors ,

Hi,

Is there a way how to get the coordinates of the box or the box object
itself drawn by a user with the GetFeature control?
Final goal is to display this box to the user.

Another thing very useful when you have a big javascript file is to minify

Subject: [OpenLayers-Users] RegularPolygon as a search polygon
Message-ID: <14429910.1278940034759.JavaMail.ngmail@webmail16.arcor-online.net>

 
Hello Brad,

I think the problem is your own separate EventHandler and the wrong handler "draw". The DrawFeature-Control has an eventhandler "featureAdded". Take this instead. 

e.g.

OpenLayers.Control.NoticeControl = OpenLayers.Class(OpenLayers.Control.DrawFeature,
{
    initialize: function(layer, handler, options) {

        OpenLayers.Control.DrawFeature.prototype.initialize.apply(this, [layer, handler, options]);

    },
    setMap: function(map) {
        this.handler.setMap(map);
        OpenLayers.Control.prototype.setMap.apply(this, arguments);
    },
    featureAdded: function(feature) {
        alert(feature.geometry.toString());
        this.deleteFeature(feature);
    },
    deleteFeature: function(feature) {
        feature.state = OpenLayers.State.DELETE;
        this.layer.events.triggerEvent("afterfeaturemodified",
                                           {feature: feature});
        this.layer.drawFeature(feature);
    },
    CLASS_NAME: "OpenLayers.Control.NoticeControl"
});

how to use:

var polyOptions = {sides: 4};
var noticeControl = new OpenLayers.Control.NoticeControl(polygonLayer, OpenLayers.Handler.RegularPolygon,
                                            {handlerOptions: polyOptions});
map.addControl(noticeControl);

hope that works

Tino

Hi there, 

Apparently not natively! But it doesn't mean it would be impossible.. You
might want to take a look at the last

I tried registering beforefeatureadded event as the definition for this
event says:

Triggered before a feature is added.  Listeners will receive an object with
a feature property referencing the feature to be added.  To stop the feature
from being added, a listener should return false.

My code:

    vectorLayer.events.register('beforefeatureadded', this,
function(feature){
        if(vectorLayer.features.length = 1){
            alert("false "+vectorLayer.features.length);
            return false;
        }else{
            alert("true "+vectorLayer.features.length);
            return true;
        }
    });

But even if I return false, the feature is added to the layer! :S

Any suggestion, please?

Thanks in advance!

Hi,

looks like your OpenLayers version is too old. This was fixed after the 2.9.1 release (http://trac.openlayers.org/changeset/10362), so you have to use a current development version.

Regards,
Andreas.

Hi Andreas,

I change my OL include (it was local) and I'm including OL from 
http://www.openlayers.org/api/OpenLayers.js
http://www.openlayers.org/api/OpenLayers.js  and still the same problem.

I modified my code to something like this:

vectorLayer.events.register('beforefeatureadded', this, function(evt){
return false; });

This event is registered just after the vectorLayer is defined.

The DrawFeature Control is this: 

dibujarPunto = new OpenLayers.Control.DrawFeature(
    vectorLayer, OpenLayers.Handler.Point,{
        title: "Dibujar",
        multi: false
    });


I got the same result! After I click the point is not shown on the map (but
the feature is added because I check the vectorLayer.features.length with
Firebug and in fact is there), if I zoom in or out the point appears.

What else may I check! I really don't know if I'm doing something wrong or
what..!

Thanks again for your time,

Gilberto Ramos

Thank you, Gilberto! 

I was wondering how I am able to use  http://ditu.google.com/ 
http://ditu.google.com/   other than  http://maps.google.com

Thanks a lot.

Well, I think this is still a bug.. I'm using the OL 2.9.1 and the solution I
found for this is:

vectorLayer.events.register('beforefeatureadded', this, function(evt){
        if(vectorLayer.features.length > 1){
           
vectorLayer.destroyFeatures([vectorLayer.features[vectorLayer.features.length-1]]);
            return true; // could be false too, does not make any difference
        }
    });

Not the sexiest way to solve the problem but it works for me.

Cheers,

Gilberto Ramos

I need to figure out what zoom level to use to be able to fully see a

Anybody ever done this? Any hints would be appreciated

You might want to look at : getZoomForExtent

http://dev.openlayers.org/releases/OpenLayers-2.8/doc/apidocs/files/OpenLayers/Map-js.html#OpenLayers.Map.getZoomForExtent

and zoomToExtent

http://dev.openlayers.org/releases/OpenLayers-2.8/doc/apidocs/files/OpenLayers/Map-js.html#OpenLayers.Map.zoomToExtent

Tino,

Thanks for that it really helped. This should be an example in OL as it
could help people like me. 

Anyway, I have one small issue which is most likely associated with my
application. I overlay a thematic WMS layer on top of my basemap and I use
this control to create a polygon to do a getFeature request against the
CubeWerx database. So I take the geometry returned in this control and turn
it into my own vector polygon to which I bind a drag control so the user can
drag it around and reuse it. I also make sure that the thematic map overlay
is set to a ZIndex that makes sure its lower than markers, other layers,
popups and this temporary vector layer etc. However, in the process of
dragging the polygon out, the display polygon appears below my thematic
overlay. Once I release the mouse it pops to the top. So is there a way of
manipulating (resetting) a control's stretching graphic?

Cheers,
Brad....

Hello Brad,

I think the problem is your own separate EventHandler and the wrong handler
"draw". The DrawFeature-Control has an eventhandler "featureAdded". Take
this instead. 

e.g.

OpenLayers.Control.NoticeControl =
OpenLayers.Class(OpenLayers.Control.DrawFeature,
{
    initialize: function(layer, handler, options) {

        OpenLayers.Control.DrawFeature.prototype.initialize.apply(this,
[layer, handler, options]);

    },
    setMap: function(map) {
        this.handler.setMap(map);
        OpenLayers.Control.prototype.setMap.apply(this, arguments);
    },
    featureAdded: function(feature) {
        alert(feature.geometry.toString());
        this.deleteFeature(feature);
    },
    deleteFeature: function(feature) {
        feature.state = OpenLayers.State.DELETE;
        this.layer.events.triggerEvent("afterfeaturemodified",
                                           {feature: feature});
        this.layer.drawFeature(feature);
    },
    CLASS_NAME: "OpenLayers.Control.NoticeControl"
});

how to use:

var polyOptions = {sides: 4};
var noticeControl = new OpenLayers.Control.NoticeControl(polygonLayer,
OpenLayers.Handler.RegularPolygon,
                                            {handlerOptions: polyOptions});
map.addControl(noticeControl);

hope that works

Tino

Hello,

I try to use this :

var drawP_create=new
OpenLayers.Control.DrawFeature(polygon,OpenLayers.Handler.Polygon,{
        title: "Draw Polygon",
        //displayClass: "olControlDrawFeaturePolygon",

        }});

But when I'm drawing a polygon the line was not under the mouse.

How can I resolved this please.

Cheers.

Subject: [OpenLayers-Users] Is there a "LikeBing" layer out there?
Message-ID: <AANLkTincG8tf4E2whWbs02jfF9P0UQKb3srwzMo4y3Us@mail.gmail.com>

Hey,

If I want to serve the Bing tiles directly, without using the VirtualEarth
wrapper layer, has that already been coded up by anyone? I know it's just a
matter of extending Openlayers.Layer.XYZ and plugging in the correct geturl
function. It's just that Bing's tile urls are based on some quadtree
nonsense that makes it slightly more of a pain that just dropping in the
coordinates.

Nevermind about whether it's a good idea or not?has it already been done, or
should I just do it myself?

Thanks!

Mike

Mind that using Bing tiles directly is a violation of the Bing Maps terms of use.

Right! that is not the intent here. I have clients that are moving away 
from Bing but have apps that are built around this tile name scheme. 
They would like to create a cache using mapserver of tiles like this for 
their other apps. being about to browse the cache in OL makes it much 
easier to develop, review and build web apps all using the same cache.

The big issue I see with this is determining an appropriate directory 
structure that maximizes tile storage in dirs so you don't have 
excessive directory overhead and that you do not have too many files in 
a directory or run out of inodes.

The quadtree structure is a little wacky, but it's nice for being able to
selectively purge your cache based on regular expressions.

Anyhow, here's the working class. Bit of a hack, but it does the trick:

var VELayer = OpenLayers.Class(OpenLayers.Layer.XYZ, {
    name: "VirtualEarth",
    attribution: "Microsoft",
    sphericalMercator: true,
    url: '/tiles/a${n}.jpeg',
    CLASS_NAME: "VELayer",

    getURL: function (bounds) {
        var res = this.map.getResolution();
        var x = Math.round((bounds.left - this.maxExtent.left) / (res *
this.tileSize.w));
        var y = Math.round((this.maxExtent.top - bounds.top) / (res *
this.tileSize.h));
        var z = this.map.getZoom();
x = x.toString(2);
 y = y.toString(2);
while(x.length < z) { x = "0" + x; }
while(y.length < z) { y = "0" + y; }
 var n = [];
for(var i = 0; i < z; i++) {
  n.push((parseInt(x[i]) + parseInt(y[i]) * 2).toString());
 }
        var url = this.url;
        var path = OpenLayers.String.format(url, {'n': n.join('') });

        return path;
    }
});

Subject: [OpenLayers-Users] geoserver 1.7.4 to 2.0.1. doesn#t show WFS any
	more
Message-ID: <1279034244563-5287927.post@n2.nabble.com>


Hi out there!

I created a demo, where there are only objects that cause problems -> see
here: http://dili-online.de/map/demo-BasisTest_gs100714.html

when I use geoserver 1.7.4. with OL 2.8 with this patch to fix the error
NS_ERROR_NOT_INITIALIZED - [nsIXMLHttpRequest.send] ->
http://n2.nabble.com/attachment/3508031/1/xmlhttprequest.patch then every
thing is fine (you cannot test ist):
- I am able to use the select tool
- I am able to use the fake tool which fakes a database application
- I can see the vector layer named "vector"

When I use the same link but send it to geoserver 2.0.1 as is now
- I am still able to use the select tool
- the fake tool causes an error
- I cannot see the vector layer named "vector" though it exists in the DOM
and is shown in the Layerswitcher Control

I want to upgrade to geoserver 2.0.1. because it is more stable than the old
version, but I need the WFS and the fake tool

Any ideas?

Thanks for answering

Barbara

Oh, and just to clarify, if you want to be naughty and link it to the actual
VE tileservers, change the url line to be:

'http://ecn.t0.tiles.virtualearth.net/tiles/a${n}.jpeg?g=0<http://ecn.t0.tiles.virtualearth.net/tiles/a03022311030202132.jpeg?g=0>
'

An obvious reason to do this in the first place though, is so that you can
use an offline cache and serve the tiles from your own machine. Again,
naughty!

But totally possible.

Hello all,

When I clicked the popup will create correctly right on point in the layer.
So I am looking for a source code which how to show the values of the popup.

this is my some source code

popup.destroy();
popup = null;
}
var ux,uy;
popup = new OpenLayers.Popup.FramedCloud("chicken",

***How can I make this code?? ***
null, 
true);
map.addPopup(popup);
}	

Can anybody suggest me?

strokeOpacity: 1,

                                                               strokeWidth:

                               })

                }

The English Translation is maybe "XML Parsing Error: No Element found

I hope someone can help me.

I know there is an easy solution to this problem just haven't found what I'm
looking for. This is my situation, I'm using FeatureServer to load my
overlay points from shapefiles to .gml . I'm using an OSM baselayer with a
reprojection from UTM to lat/lon. What I want to do is display point symbols
using a ratio to the attribute value aka proportional symbols.Is there an
Openlayers.get.attribute or something along those lines that I can pull an
attribute value from the gml or is this a matter of hacking JavaScript to
get the results I'm looking for.

I want to add a form to openLayers just like the layer switcher. Could some

OpenLayers.Control ?

Hi,

I want to add a new control like LayerSwitcher, OverviewMap on the map with
a form in that control. This form enables the user to enter their search
queries. Is there a control like LayerSwitcher available to embed my form ?
Or any inputs to develop a new control ??

I find it very hard to read the OpenLayers.js as it is compressed to reduce
the size. Is there a way to get it back to a readable format ?

Thanks,
Kalyan

The source is in the package in lib/OpenLayers.
To debug your code you can link to lib/OpenLayers.js and use Firebug.

Hi,

your WFS configuration for 2.0.x seems to be different. You are using a wrong featureNS. Try http://www.dili-online.de:8090/geoserver/demo_kunde1 instead of http://www.dili-online.de/geoserver/demo_kunde1

Regards,
Andreas.

Hi

We are using OpenLayers in our application.  We are adding a Google map
layer to the map.  Using Openlayers, is it possible to perform Google Map
Directions as shown here:
http://code.google.com/apis/maps/documentation/javascript/services.html#Directions

If yes, which version of OpenLayers should we be using?  We are currently
using 2.8.

Message-ID: <AANLkTilPut0rw1DqwJe0Hre6XJKZo5sR4rAzUeGh5d0q@mail.gmail.com>

Hi list,

I`m tying to add a Geometry Collection which consists of a line
feautre and a point, the point is a arrow head to be place at the end
of line, however It seems the constructor is not taking a geometry
object, which seems to be adding to a simple vector layer, I tried the
code in FireBug, but it shows undefined. this is how I`m trying to do.


pointList is an array of OpenLayer points and works if the line string
is added to a feature.vector object,

pointList.toString() returns "POINT(73.13187817700006
33.59365778950007),POINT(73.12991075150003 33.59738348500005)"



var gc = new OpenLayers.Geometry.Collection([new
OpenLayers.Geometry.LineString(pointList)]);

what am i doing wrong here.

regards,
Imran

another method is to build an uncompressed file by using the python-script "buildUncompressed.py" in the Folder "build".

If you want to create a new form, then create a new class which inherits from control:

OpenLayers.Control.YourControl = OpenLayers.Class(OpenLayers.Control, {

    initialize: function(options) {
        
        OpenLayers.Control.prototype.initialize.apply(this, [options]);
    },
    
    .....

    CLASS_NAME: "OpenLayers.Control.YourControl"
});

If you need a container for your control, use the class "Panel".

hope that helps

Tino

I think that must be a security problem, because I can open the wfs source
with qgis and try some different openlayers codes.

 

Maybe the Port 8080 is blocked?!

I have seen that some people here use the 8090 port for catching the
geoserver wfs source.

 

Is here somebody had the same problem?

 corner to bottom-left corner
Message-ID: <4C3D9D73.3000103@romtelecom.ro>

Hello,

I'm trying to move the layer switcher button from the top-right corner 
of the map to the bottom-left corner. I have done this before with 2.8, 
but I ended up making changes in the openlayers API, but I can see now 
that 2.9.1 seems to have made changes in the LayerSwitcher's definition.
I'm trying to override just some CSS rules to move the button where I 
want it, and also, make changes to display the minimize button on the 
left side of the expanded div (instead of having it on the right side).

Before I show you my hacked-up code, I'd like to ask: has anyone moved 
it and can I get some sample code?

Thanks,
Adrian

Hello,

 

I want to get from a GeoServer WFS a Layer in OpenLayers

A very simple problem, but nothing is working. Sorry.

 

When I get the Data with WMS all is fine.

 

I have try the following Code:

 

new OpenLayers.Layer.Vector("WFS", {

                        strategies: [new OpenLayers.Strategy.BBOX()],

                        protocol: new OpenLayers.Protocol.WFS({

                            version: "1.1.0",

                            srsName: "EPSG:31467", // this is the default

                            projection: "EPSG:31467",

                            url:  "http://zimrob.com:8080/geoserver/wfs",

                            featureType: "pcd_incidents",

                            featureNS: "http://www.zimrob.com/crimewebgis"

                        }),

                        projection: "EPSG:31467", // specified because it is
different than the map

                        styleMap: styleMap

  })

 

http://zimrob.com:8080/geoserver/wfs still working.

My Map definition is this:



var map = new OpenLayers.Map('map', {

                               controls: [

                                               new
OpenLayers.Control.Attribution(),

                                               new
OpenLayers.Control.MouseDefaults(),

                                               new
OpenLayers.Control.PanZoomBar(),

                                               new
OpenLayers.Control.MousePosition()],

                               projection : 'EPSG:31467',

                               maxResolution: 800,

                               units: 'm',

                               fractionalZoom: true,

                               maxExtent: new OpenLayers.Bounds(3146150,
5223600, 4031150, 6108600)

    });

 

I hope your can help me.

Subject: [OpenLayers-Users] Creating styles based on the values of
	calculated variables.
Message-ID: <A7DF91C2-ED7D-4A49-A4A1-915C0050A68A@dheerajchand.com>

Hello, everyone!

First time poster, here.  I'm pretty new to JS, in general, and OpenLayers, particularly, but I'm really enjoying it so far. 

I am curious if anyone has done something like what I am trying to do.  My goal is to allow a user to select any two variables by means of a form.  These variables could be, say, the number of people in Texas, by county, from 1991 to 1999.   The goal is then to create a new variable, Var3, where Var3 = (Var1 - Var2) and then style  the entire map based on the value of Var3.  (Each variable would obviously represent an attribute of the layer) I have got everything down except how to build a style based on the value of a derived variable.  Any advice?

Thanks!

Not sure if this is exactly what you're looking for, but it's possible to have a
style that has function-backed portions:

Not to state the obvious but are  you adding the layer to the map?

 

var layer = new OpenLayers.Layer.Vector ...

 

map.addLayers([layer]);

Hello,

 

I want to get from a GeoServer WFS a Layer in OpenLayers

A very simple problem, but nothing is working. Sorry.

 

When I get the Data with WMS all is fine.

 

I have try the following Code:

 

new OpenLayers.Layer.Vector("WFS", {

                        strategies: [new OpenLayers.Strategy.BBOX()],

                        protocol: new OpenLayers.Protocol.WFS({

                            version: "1.1.0",

                            srsName: "EPSG:31467", // this is the
default

                            projection: "EPSG:31467",

                            url:

                            featureType: "pcd_incidents",

                            featureNS:
"http://www.zimrob.com/crimewebgis"

                        }),

                        projection: "EPSG:31467", // specified because
it is different than the map

                        styleMap: styleMap

  })

 

http://zimrob.com:8080/geoserver/wfs still working.

My Map definition is this:

var map = new OpenLayers.Map('map', {

                               controls: [

                                               new
OpenLayers.Control.Attribution(),

                                               new
OpenLayers.Control.MouseDefaults(),

                                               new
OpenLayers.Control.PanZoomBar(),

                                               new
OpenLayers.Control.MousePosition()],

                               projection : 'EPSG:31467',

                               maxResolution: 800,

                               units: 'm',

                               fractionalZoom: true,

                               maxExtent: new OpenLayers.Bounds(3146150,
5223600, 4031150, 6108600)

    });

 

I hope your can help me.

Hi,I have a bounding box with this coordiate:- minx miny;- maxx maxy.
So I would center my map on this coordinate.How I have to do it?
I have seen:map.setCenter();
but I don't know what kind of parameters I have to use.
How I can do it?
Thanks a lot.

Ok thanks, I have used:map.zoomToExtent(new OpenLayers.Bounds(parseFloat(coord[0]),parseFloat(coord[1]),parseFloat(coord[2]),parseFloat(coord[3]) ?));					And if I would draw a boundin box with these coordinate?
How can I do?

Sorry but I am not expert.
Thanks again.

Hi,

Use for your gml layer the option extractAttributes: true to get features
with attributes.

Use a styleMap for your layer, where your pointRadius is set by an attribute
:

var template = {
    strokeColor: "#0000FF",
    ...
    pointRadius: "${yourAttribute}"
};

styleMapRotation = new OpenLayers.StyleMap(new OpenLayers.Style(template));


or you use a styleMap with context, if you want calculate the radius by
other conditions :

function set_styleMapRotation()
{
    var context = {
        getPointRadius : function(ft){
            var zoomOffset = map.projection == "EPSG:4326" ? 1 : 8;
            var fktr=1;
            var diffZ = map.getZoom() - zoomOffset;
            return diffZ > 0 ? 7 + 3*diffZ*fktr : 8;
        }
    };
    var template = {
        strokeColor: "#0000FF",
        ...
        pointRadius: "${getPointRadius}"
    };

    styleMapRotation = new OpenLayers.StyleMap(new
OpenLayers.Style(template, {context:context}) );
}
set_styleMapRotation();

Example with pointRadius set by the attribute for the population of cities
and label size by zoomLevel

Betreff: [OpenLayers-Users] Proportional Symbols from

I know there is an easy solution to this problem just haven't found what I'm
looking for. This is my situation, I'm using FeatureServer to load my
overlay points from shapefiles to .gml . I'm using an OSM baselayer with a
reprojection from UTM to lat/lon. What I want to do is display point symbols
using a ratio to the attribute value aka proportional symbols.Is there an
Openlayers.get.attribute or something along those lines that I can pull an
attribute value from the gml or is this a matter of hacking JavaScript to
get the results I'm looking for.

I wonder what the value of 'radii' would be before any pan/zoom takes place.

Once set here, the 'radius' attribute won't be updated on pan/zoom.

Subject: [OpenLayers-Users] Scale dependent layer problems
Message-ID: <1279157834653-5295582.post@n2.nabble.com>


Hi, I'm just putting together my first OL map and have run into a problem.
The map is using Bing maps for the base and several WMS overlays. I'm trying
to make a layer scale dependent with no success and have been through all
the tips I could find in the forums. I'm obviously missing something and am
questioning whether I've configured the resolutions and extents correctly
also. Here is the relevant code:

//Configure map
	var options = {

Try using 'minScale': 1000000 or 'maxScale': 1000000

Hi,

thanks for the relpy, well I need this arrow to resize with the zoom
in... radii will remain between  1 to 10.. ,. so I`m just trying to
set to 10 when the map is zoomed in maximum. do I need to write an SLD
and import it? but my geometry type is collection a collection of line
and point feature, wonder how will sld react to that .. thanks
anyway.

regards,
Imran

@ Ralph: yes I had add the layer to the map.

 

The solution is to install a proxy.cgi.

Thanks Tino!

Not to state the obvious but are  you adding the layer to the map?

 

var layer = new OpenLayers.Layer.Vector .

 

map.addLayers([layer]);

Hello,

 

I want to get from a GeoServer WFS a Layer in OpenLayers

A very simple problem, but nothing is working. Sorry.

 

When I get the Data with WMS all is fine.

 

I have try the following Code:

 

new OpenLayers.Layer.Vector("WFS", {

                        strategies: [new OpenLayers.Strategy.BBOX()],

                        protocol: new OpenLayers.Protocol.WFS({

                            version: "1.1.0",

                            srsName: "EPSG:31467", // this is the default

                            projection: "EPSG:31467",

                            url:  "http://zimrob.com:8080/geoserver/wfs",

                        }),

                        projection: "EPSG:31467", // specified because it is
different than the map

                        styleMap: styleMap

  })

 

http://zimrob.com:8080/geoserver/wfs still working.

My Map definition is this:

var map = new OpenLayers.Map('map', {

                               controls: [

                                               new
OpenLayers.Control.Attribution(),

                                               new
OpenLayers.Control.MouseDefaults(),

                                               new
OpenLayers.Control.PanZoomBar(),

                                               new

                               projection : 'EPSG:31467',

                               maxResolution: 800,

                               units: 'm',

                               fractionalZoom: true,

                               maxExtent: new OpenLayers.Bounds(3146150,
5223600, 4031150, 6108600)

Thanks for replying Bryan,

min/maxScale isn't working either. It seems like a number of layer
properties are being ignored. I've even tried just setting visibility:
'false' to see what happens and the layer still loads.
I also tried to just do a work around using getResolution and an if
statement, but getResolution always returns null.

if (map.getResolution() < 1)
  {vis = 'false'}
else
  {vis = 'true'}

Hello list,

 

We use OpenLayers since 4 years and the results are very satisfactory. Nowadays, We are planning to make a step foreward using MapFIsh. Somebody has experience with this framework? What's your opinion versus OL?

 

In my first sight, I think MapFish too complex.

 

What do you think?

 

Thanks in advance.

Hi,

I think you need to differentiate between MapFish and GeoExt.

GeoExt adds a nice looking GUI to OpenLayers, it's all still javascript. GeoExt is also used by MapFish.

What is complex in your opinion?

MapFish is more than just a client webmapping package, it's a full web-mapping solution, so server-side + client-side.

With most map API's a person can track an object. If not by an ID at least by
a instance. So if I make a OpenLayers.Feature.Vector and need to update its
lat and lon, color, or find this objects id/reference later when mouse
overed or down, how is that done?

Subject: [OpenLayers-Users] Problem with Google layers positioning after map
	resize
Message-ID: <20100715141000.159350@gmx.net>

Hello

I stumbled over a problem with Google layers and a map resize that looks similar to the one described here:

http://trac.openlayers.org/ticket/1797

The problem appears if I have a Google layer activated, then switch to another non-Google base layer, change the map size via a GUI functionality (after resize of the map DIV the map.updateSize() method is applied), and then switch back to the Google layer. The Google layer has then not been correctly updated to the new map size, it means that the layer tiles are not moved correctly. If I then use the pan tool the map tiles are very strangely moved and the map extent is completely messed up.

You can find this affect on an application here:
http://cidportal.jrc.ec.europa.eu/imagearchive/main/

resizing the map is done with the thin bars at the left/bottom of the map.

The strange thing is that I noticed this behaviour only very recently, I mean in the last days. Before, neither me nor my colleague can remember having seen this behaviour. But our code and the OpenLayers library have not changed in the meantime. I tried the same now on a test server with the new OL 2.9 but still get the same strange effects.

I don't have a clue what could have happened and causes this problem. I could only think of a change in the Google API since this is always downloaded for every new access.

Any help or hint would be very appreciated. I can provide more details if required.

Best regards
Armin

Thanks Bryan, that did it, though I had to use minResolution rather than
minScale. Not to pester, but why did this work over setting all properties
in one set?

Thanks again,

Have a look at the OpenLayers.Layer.WMS Constructor documentation I
referenced in my post above.

OpenLayers.Layer.WMS Parameters:

name      {String} A name for the layer
url          {String} Base url for the WMS (e.g. 
http://wms.jpl.nasa.gov/wms.cgi)
params    {Object} An object with key/value pairs representing the GetMap
query string parameters and parameter values.
options    {Ojbect} Hashtable of extra options to tag onto the layer

The first set of params define the GetMap request while the second set of
options are OL specific API properties.

Because the first group are parameters for the WMS server and the
second set are options for OpenLayers. WMS knows nothing about
minScale (or minResolution) and isBaseLayer etc so it ignores them.

Ah, I see now. I didn't find this particularly clear in the documentation but
thanks enormously for setting me straight.

hey, thx. I think my bigger issue is this..

http://dev.openlayers.org/releases/OpenLayers-2.9/doc/apidocs/files/OpenLayers/Feature-js.html

vs

http://dev.openlayers.org/docs/files/OpenLayers/Feature-js.html

the top is a stripped down no option version of the bottom, what am I
missing here? The second link has what i would have expected. so what the
first link all about?

So SelectFeature  will get me my reference, can I get it during
construction.

"There are two types of properties/methods in the OpenLayers code: One set is the set of API Methods and properties. There are also additional internal properties which are not exposed to the API. Javascript does not have private members, so there is no technical limitation to using these non-documented methods in Application code. However, while we make every effort not to change APIs between releases, methods and properties which are not explicitly declared as API Methods may change in minor releases.

The documentation above only includes the API Methods. Full developer/internal library documentation is also available below, but methods which are not available in the API documentation above can not be depended upon to stay the same between releases. If you use methods included in these docs, you may have to make modifications in your application code to run between minor releases of OpenLayers."

Subject: [OpenLayers-Users] Doing something when the layer's features get
	deleted
Message-ID: <4C3F1CE5.1000108@romtelecom.ro>

Hello everyone,

I have a problem with popups and a vector layer  - if I trigger a forced 
refresh on the vector layer while a popup for a feature is opening, the 
popup's div will freeze and I am unable to close it (most likely because 
the feature it was bound to gets deleted by the time the popup opens). 
Is there any way I can catch a signal/event for layer refresh (just 
before the layer's features get deleted) and abort/close the popup opening?

Thanks,
Adrian

ok very good. 

Still not getting the result I'd expect with this code.
[code]
var linearRing = new OpenLayers.Geometry.LinearRing(points);
	 var obj = new OpenLayers.Geometry.Polygon([linearRing]);
     var polygonFeature = new OpenLayers.Feature.Vector( obj );

            shapeLayer.addFeatures(polygonFeature)
			return polygonFeature;
[/code]
I know the object gets put on the map(shapeLayer), as I can see it but the 
returned value.fid is null? Also according to some of what I read
"MapTools.shapeLayer.addFeatures(polygonFeature)" should return an array of
what was added, but its always undefined.

Subject: [OpenLayers-Users] Get the value of the element of an XML File
Message-ID: <AANLkTinZBo-lm2GQjc5aEFXZfC3nTpGF46GG_ta_aybO@mail.gmail.com>

Hi all,

I'm trying to get the value of an XML file  from an external server.
Below are the steps I do.

1/ I download this XML file with a classic Ajax request :

var getVesselsXML = new OpenLayers.Ajax.Request(
urlVessels,
                                {
                                  method: 'get'
                                  ,onSuccess : drawVessels
                                  ,extractAttributes: true
                                }
                        );

The result of the request is :

"<POSITIONS>
<V_POS LAT="42.35675" LON="4.2338452" N="RED COUGAR" T="9" H="43"
S="53" F="ES" M="225350000" L="32" E="5" />
<V_POS LAT="42.532299" LON="4.35115" N="AQUAGLORY" T="7" H="217"
S="157" F="GR" M="240119000" L="289" E="2" />...
</POSITIONS>"

2/ In the drawVessels method I parse the result  :

var XmlFormat = new OpenLayers.Format.XML();
vessels = XmlFormat.read(XmlvesselsRequest.responseText);

But I don't know how to get the attributes of a specific node. For
example, how can i Get the LON and the LAT of each node ?

I already tried somethings like that but it return me an empty string :

vessel = XmlFormat.getElementsByTagNameNS(vessels,'*','V_POS');

for (i in vessel){
   var LAT = XmlFormat.getAttributeNS(vessel[i],'*','LAT');
   console.log(LAT);
}



Thanks for your help


Best Regards

Arnaud

Hi,

I have a problem with my with WMS Layer:
?
I have a raster image in tif format. When I overlay it in the map, A

shown as black and annoys the visual appearance. Is it possible to 
switch it into transparent? 
?
I have tried to change the opacity and transparent:true in the layer params, but it does'nt work.

(I am using GeoServer and OpenLayers)

Any help is appreciated.

Thank you,

	with SLD style
Message-ID: <F8C1A631-56F2-4468-9C87-841BC6C0BF52@dheerajchand.com>

Hi, everyone,

I posted just the other day about a map that I'm building.  The idea has been changed to a simpler one.  Through a form, the user constructs a variable that represents the attribute to be considered, then a style is built and attached to the layer in question and the layer is redrawn.  It should be fairly simple, but my newness to JS and OpenLayers is getting in the way.

I seem to have all kinds of problems with this map,1) For some reason, battlegroundData is rendering as a base layer, not an overlay, 2) I think that something is wrong with the projection and 3) I'm not sure whether I read the documentation correctly for writing the style SLD and then attaching it.  

Mind helping a brother meet his deadline?  http://gulfcoaststrategicservices.com/maps/lrp/index.html

Dheeraj,

Check this thread to fix your overlay/basemap issue: 
http://osgeo-org.1803224.n2.nabble.com/Scale-dependent-layer-problems-td5295582.html#a5297365
http://osgeo-org.1803224.n2.nabble.com/Scale-dependent-layer-problems-td5295582.html#a5297365
.

Once you switch this to an overlay, it should reproject to match up with
your Google basemap layers.

    sld["namedLayers"][namedLayer]["namedStyles"] = [];

    var formatSLD = new OpenLayers.Format.SLD();
    return(formatSLD.write(sld).replace(/\n/g,""));

Hi,

I'm using the cluster strategy and selectFeature control on a vector
layer, and the selection is not sticking when I zoom in and out.  This
makes sense: if two features, one selected and one unselected, are
clustered the selection state is ambiguous.  But I'd still like to
come up with a solution.  Is there a way to do this or could anyone
suggest a direction to take.

Thanks a lot,

Hi I'm having the same trouble - I'm overlaying georss layers, but I'm
finding that if I have multiple markers at the same gps location, I am only
seeing one marker. Is there a way of "exploding" the results when the on
click event is fired (like google maps). Is this a bug in openlayers?

I am using some large images for baselayers. I want to calculate min/max 
resolution so that you can zoom out far enough to view the entire image 
and zoom in to the point where you have pixel for pixel match. I am 
finding this harder to calculate than I thought. Can someone give me 
some tips please?

Subject: [OpenLayers-Users] WFS reprojection help
Message-ID: <CA7F7D9E-5009-42CA-868B-D8A245C66B0C@nokia.com>

Hi,

I have a map that I think should work at:

 http://crschmidt.net/mapping/mas/wfs-states.html

This is a minimal modification of the wfs-states.html included in the examples. 

Specifically, I've added: 
 * Proj4js lib 
 *         <script src="http://spatialreference.org/ref/epsg/26986/proj4js/"></script>

And modified the layer to be a simple layer that requires reprojection.

    var wfs = new OpenLayers.Layer.Vector("States", {
        strategies: [new OpenLayers.Strategy.BBOX({ratio: 1.1})],
        protocol: new OpenLayers.Protocol.WFS({
            url: "http://giswebservices.massgis.state.ma.us/geoserver/wfs",
            version: '1.0.0',
            featureType: "GISDATA.CENSUS2000BLOCKGROUPS_POLY",
            geometryName: 'SHAPE',
            featureNS: "http://massgis.state.ma.us/featuretype"
        }),
        projection: new OpenLayers.Projection("EPSG:26986")
    });

The layer in question is being requested from the server with an srsName that matches
the projection, but the coordinates are wrong (EPSG:4326).

I've looked at the wfs-reprojection example; I've tried adding srsName
to the protocol with no additional luck.

Help?

Regards,

Subject: [OpenLayers-Users] Newbie Question about releases
Message-ID: <4C406CAC.921E.0047.0@justice.govt.nz>

Hi All,
 
Apologies for the Newbie question however I wanted to ask some questions about releases and checking openlayers out from subversion.
 
When I use the command:
svn checkout http://svn.openlayers.org/trunk/openlayers/ ( http://svn.openlayers.org/trunk/openlayers/ )
I get 405 access denied.  So can anyone tell me how you check out the trunk of openlayers?
 
Secondly I have read about 2 branches openlayers currently has going.
What are the release time frames for the
2.x branch
and for 3.0 branch
 
I have managed to check out 3.0 trunk from http://github.com/openlayers/openlayers.git 
However I am unable to figure out how to check out 2.x from this source system anyone tell me how to do that?
I tried http://github.com/openlayers/openlayers/tree/2.x this is obviously wrong.
 
Regards Wendy

Does SVN work for you at all? Usually this would mean your'e behind a
proxy which blocks PROPFIND access, so you can't check out any SVN;
have you tried on a different network, or using a different HTTP proxy
or anything else? 

This works for me.

"Whenever they're done." 2.x is likely "next 6 months", 3.x is likely
"before the sun explodes", but those are rough estimates.

OpenLayers core/trunk is not maintained in git, just our playground for 3.x.
As such, the way to checkout the current 2.x work is via SVN.

Hello all,

How can the popup show the information if I give the value of ux and uy.
If the function looks like this,

function popup_s(ux,uy)
					{										
					if (popup != null) {
            			popup.destroy();
		            	popup = null;
        				}															
						var ux,uy;					
					 	popup = new OpenLayers.Popup.FramedCloud("chicken", 
						new OpenLayers.LonLat(ux,uy), 						
						null,						
						event.text, <<----How could it be?
						null, 
                        true					
						);
					map.addPopup(popup);
					map.setCenter(new OpenLayers.LonLat(ux, uy), 2);
				}

Any suggestion? 
Thank you.

Hello Bart and Hugo,

 

I'm new with MapFish, I've just installed and done some basic tests. 

 

First of all, I don't understand how it works pylons virtual environment. Anyway, I'm interested in client side of MapFish to build a Rich web mappinng application. Now We use OL over an apache server and it's a clear and tipical structure of files and data. When We need to create a new component, we extends OL classes creating new js files. Server side components are created using servlets or php and client comunicates with them using ajax.

 

I don't understand how the same can be do it with MapFish. I think there are a great dependency with python server environment.

Hi,

 

I think you need to differentiate between MapFish and GeoExt.

 

GeoExt adds a nice looking GUI to OpenLayers, it's all still javascript. GeoExt is also used by MapFish.

 

What is complex in your opinion?

 

MapFish is more than just a client webmapping package, it's a full web-mapping solution, so server-side + client-side.

In my first sight, I think MapFish too complex.

 

What do you think?

 

Thanks in advance.

shown as black and annoys the visual appearance. Is it possible to 
switch it into transparent? 
 
I have tried to change the opacity and transparent:true in the layer params, but 
it does'nt work.

(I am using GeoServer and OpenLayers)

Any help is appreciated.

 
Thank you,

Hello all,

How can the popup show the information if I give the value of ux and uy.
If the function looks like this,

function popup_s(ux,uy)
                    {                                        
                    if (popup != null) {
                        popup.destroy();
                        popup = null;
                        }                                                        
    

                        var ux,uy;                    
                         popup = new OpenLayers.Popup.FramedCloud("chicken", 
                        new OpenLayers.LonLat(ux,uy),                         
                        null,                        
                        event.text, <<----How could it be?
                        null, 
                        true                    
                        );
                    map.addPopup(popup);
                    map.setCenter(new OpenLayers.LonLat(ux, uy), 2);
                }

Any suggestion? 
Thank you.

Hi,

did you see this (you can even look at examples pages of OL):
var infoControls =     
            new OpenLayers.Control.WMSGetFeatureInfo({ 
            url: 'http://xxxxx:8080/geoserver/wms?',
            title: 'Identify features',
            infoFormat: 'text/plain',
            queryVisible: true,
            eventListeners: {
            getfeatureinfo: function (event){ 
                        map.addPopup(new OpenLayers.Popup.FramedCloud(
                            "chicken",
                            map.getLonLatFromPixel(event.xy), 
                            null,
                            null,
                            event.text,
                            null,
                            true)); 
                    }
            }    
        });

Any clues about this?

I'm trying with:

myLayer = new OpenLayers.Layer.WMS('myLabel'
					WMSURL, 
					{layers: myMap.geotiff,
					transparent: 'true',
					opaque: 1,
					format: 'image/png8',
					bbox:
'1033428.6,5520587.9,1413779.3,5675907.9',//'9.22,43.8,12.7,45.15',
					srs: 'EPSG:900913'}
                     );

myMap.geotiff is far larger than the defined bounding box, but still the
entire map is returned.

Any idea?
Thanks.
Piero

Hi Tim,
ok so you can get the HTTP WMS request URL of a certain layer with that:

var request = layer.getURL(map.getExtent()); 

where you input the BBOX.

But whether I want to test which was the actual BBOX I requested when I did
the HTTP request?
How do I get the HTTP WMS GetMap request I did when I downloaded the layer?

Firebug does not track it in the console.

Any clue?
Thank you guys.
Piero

Subject: [OpenLayers-Users] OpenLayers in an Eclipse Workbench!?
Message-ID: <4C403B00.8000705@polymap.de>

Hello all,

my name is Falko Br?utigam. I'm a core developer of the POLYMAP3 project. I 
would like to introduce this project here to see what other OpenLayers users 
think about the idea of bringing together the power of OpenLayers, Eclipse 
Workbench, OSGi and GeoTools.

POLYMAP3 aims to provide a spatial data workbench and OGC server. We have been 
working on the project for 8 months now. It is a complete rewrite of an existing 
codebase. It is based on Eclipse/RAP, qooxdoo, OpenLayers, GeoTools, uDig, 
JGrass and a lot of other great open source software components.

   * uses OpenLayers as the map component
   * uses Eclipse Workbench UI
   * GeoTools core
   * extensible architecture based on Eclipse/OSGi framework
   * multi-user

OpenLayers is a great software project. It is one of the core components of our 
project. Many thanks the all the developers.

A lot of work has been done so far for the development of POLYMAP3. However, the 
project is in early stage and there are still a lot of things to do. Especially 
for advanced feature editing functions based on OpenLayers there are open 
issues. Any help with this or any other issue or feedback would be greatly 
appreciated.

POLYMAP3 is an open effort to build a web-based spatial data workbench for each 
and everything and nothing in particular. The UI is much like uDig but 
multi-user and runs in the browser. Based on Eclipse the architecture is very 
open. Basically it can be extended in any way.

Please check the project site at: http://www.polymap.org/wiki

Thanks,

Falko

Hi list

I'm trying to find info about how to customize the PanZoomBar

First I would like to customize the height of the default one, my map is in fractionnedZoom mode and I would like the zoom bar having a defined height, how I do that, I have to play with css styles I guess ?

How about changing the images  making the zoombar?

I tried to search the list using the Nabble search but it's broken, keep returning a java exception...

Subject: [OpenLayers-Users] working with features
Message-ID: <1279286987431-5301904.post@n2.nabble.com>


Here is the code I'm using to create

	 var linearRing = new OpenLayers.Geometry.LinearRing(points);
	 var obj = new OpenLayers.Geometry.Polygon([linearRing]);
     var polygonFeature = new OpenLayers.Feature.Vector( obj );
	shapeLayer.addFeatures(polygonFeature)
	return polygonFeature;

All I really need is a way to get and set very common data. For example lat
and lon position. If I try to use the Properties from JS I see most of them
are null? So this must not actually be Properties. Secondly if I trace a
function like createMarker the entire function is "return null;" So my guess
is the API is not complete. Surly there is a way to get and set the
position. Making  a feature work like a marker would be ideal as it seems
the marker class is complete.

I have been able to modify the style property, but generally speaking this
should be done via a function. The weird thing here is that I can create a
red shape, change it to blue just fine. Create another but this time I can
not change the color. 

It looks like the id property is working fine, is there a getById class that
has access to object control?

I think you'll need to use version 1.1.0 of the WFS spec to get
reprojection. 1.0 only supports 4326.

response:

                                             , 'styleMap': layerStyle
                                             , 'extractAttributes': true
                                            }
                                            );

map.addLayer(wfs);

But this one, that I found somewhere in the examples or forums, doesn't:

var layer = new OpenLayers.Layer.Vector("Guybrush Threepwood", {
                strategies: [new OpenLayers.Strategy.BBOX()],
                protocol: new OpenLayers.Protocol.WFS({
                    version: "1.1.0",
                    url: "http://localhost:2006/GetFeature.ashx",
                    featureType: "miwfs:MonkeyIsland",
                    featureNS: "http://www.mapinfo.com/wfs",
                    geometryName: "VL_GMTR",
                    srsName: "EPSG:4326"
                }),
                projection: new OpenLayers.Projection("EPSG:4326")
            });

map.addLayer(wfs);

If helps, my map object is:

var map = new OpenLayers.Map("map", {
        projection: new OpenLayers.Projection("EPSG:900913"),
        units: "m",
        maxResolution: 156543.0339,
        maxExtent: new OpenLayers.Bounds(-20037508.34, -20037508.34,
20037508.34, 20037508.34),
        numZoomLevels: 21
    });

and my baseMap is:

var myBaseLayer = new OpenLayers.Layer.Google("Google",
              { 'sphericalMercator': true
              , 'numZoomLevels': 21
              , 'minZoomLevel': 1
              , 'maxZoomLevel': 21
              });

    map.addLayer(myBaseLayer);

Sorry for the long post.

Without seeing your actual WFS it is hard to help.

But here it goes:

1) featureType should be MonkeyIsland
2) check if your featureNS does not end with / in the XML returned by your
WFS, this would also break the parser. So maybe
http://www.mapinfo.com/wfs/ instead of http://www.mapinfo.com/wfs

Reprojection should be working on the client side; there's an example
of it in:

  http://openlayers.org/dev/examples/wfs-reprojection.html

"In the case where the projection of a vector layer differs from the projection of the map, features are requested in the layer projection and transformed during parsing. It is assumed that the layer projection is "native" projection of the data (the coordinate reference system of the data on the server)."

Additionally, though this map doesn't work in Safari when I first load
it, when I zoom in or out, the map *does* load. (In Firefox, it doesn't 
at all.) So this seems like it's more complex than "ur doin it wrong",
though maybe I'm still missing something obvious.

Hi Christopher,

Maybe this will help: try using proj4js-compressed.js, instead of proj4js.
It worked for me, when I had trouble with compatibility (IE, FF, Chrome).

Zoran:

Perfect! That did what I needed. This is what I get for skipping
setting up my own proj4js lib. I figured it was a loading issue,
but couldn't figure out what it was.

I've made some changes in the request, namely the version and featureNS, and
now it looks like this:

var layer = new OpenLayers.Layer.Vector("Guybrush Threepwood", {
                 strategies: [new OpenLayers.Strategy.BBOX()],
                 protocol: new OpenLayers.Protocol.WFS({
                     version: "1.0.0",
                     url: "http://localhost:2006/GetFeature.ashx",
                     featureType: "MonkeyIsland",
                     featureNS: "http://www.opengis.net/wfs/",
                     geometryName: "VL_GMTR",
                     srsName: "EPSG:4326"
                 }),
                 projection: new OpenLayers.Projection("EPSG:4326")
             });

             map.addLayer(layer);


By the way, my WFS server has the following Features:

http://localhost:2006/GetFeature.ashx?service=WFS&version=1.0.0&request=DescribeFeatureType

<schema targetNamespace="http://www.mapinfo.com/wfs"

Hi there,

Try something like this:


    var wfs = new OpenLayers.Layer.Vector("wfs", { 
        strategies: [new OpenLayers.Strategy.BBOX()],
        projection: new OpenLayers.Projection("EPSG:4326"),
        protocol: new OpenLayers.Protocol.WFS({
            version: "1.1.0",
            srsName: "EPSG:4326",
            url: "http://192.168.224.128:8080/geoserver/wfs", 
            featureType: "khasra", 
            featureNS: "http://192.168.224.128:8080/geoserver", 
            schema:
"http://192.168.224.128:8080/geoserver/wfs?service=wfs&version=1.1.0&request=DescribeFeatureType&typename=CHANGETHIS:khasra",
            featurePrefix: "CHANGETHIS"
        }) 
    }); 


Obs.: The CHANGETHIS part you can look at the Preview Layers section in
GeoServer Admin..

Cheers,

Gilberto Ramos

Eduardo,

featureNS should be http://www.mapinfo.com/wfs in your case.

What do you see using Firebug? Does the request go off at all? Does the
WFS respond with a proper FeatureCollection? Can you share a snippet of
the response?

Best regards,
Bart

Bart, thanks for your time.

The request doesn't go off at all... firebug console is empty. No javaScript errors or warnings... 

It adds the layer name to the layer control but nothing else happens.

Edu

Subject: [OpenLayers-Users] Moving LayerSwitcher position from top-right
 corner to bottom-left corner
In-Reply-To: <34577.145.50.39.11.1279262703.squirrel@webmail.hostingdiscounter.nl>
References: <4C3D9D73.3000103@romtelecom.ro> <4C3FFF4C.4020304@romtelecom.ro>
	<34577.145.50.39.11.1279262703.squirrel@webmail.hostingdiscounter.nl>
Message-ID: <4C406F80.5020303@romtelecom.ro>

I studied CSS extensively the past two days, and I sort of managed to 
move it, but I still have two problems:

1. I can't position the layer-switcher-maximize button if I want to add 
an offset measured from the bottom (bottom: 40px). I can only display it 
if I specify an offset from the top - but my map size is not fixed, and 
I would like to have it linked to the bottom of the map. The rest of the 
div and the minimize button are displayed as expected.

Here is my CSS override code:
<style>
      .olControlLayerSwitcher {
         /*  position: absolute;
           top: 25px;
           right: 0px;
         */
           width: 20em;
           font-family: sans-serif;
           font-weight: bold;
           margin-top: 3px;
           margin-left: 3px;
           margin-bottom: 3px;
           font-size: smaller;
           color: white;
           background-color: transparent;

           position: relative !important;
           top: 350px !important;
           right: auto !important;
           bottom: auto !important;
           left: 0px !important;
           /* if I set top: auto !important and bottom: 40px !important, 
the div is no longer drawn on the screen */

      }
      .olControlLayerSwitcher .layersDiv {
          padding-top: 5px;
          padding-left: 0px !important;
          padding-bottom: 5px;
          padding-right: 0px !important;
          background-color: darkblue;
          width: 100%;
          height: auto !important;
     }

     .olControlLayerSwitcher .layersDiv .baseLbl,
     .olControlLayerSwitcher .layersDiv .dataLbl {
          margin-top: 3px;
          margin-left: 3px;
          margin-bottom: 3px;
     }

     .olControlLayerSwitcher .layersDiv .baseLayersDiv,
     .olControlLayerSwitcher .layersDiv .dataLayersDiv {
          padding-left: 10px;
     }

     .olControlLayerSwitcher .maximizeDiv,
     .olControlLayerSwitcher .minimizeDiv {
          top: auto !important;
          right: auto !important;

          position: absolute !important;
          bottom: 40px !important;
          left: 0px !important;
     }


2. It seems that the corner effect in the layer selection div is done by 
having some spans with variable margins - but the problem is - these 
margins are designed only to generate the left rounded corner. I need to 
adapt them to generate the rigth corner with the same margin as the left 
corner. Question is - since there are no classes or ids, can I do this 
without changing the OL API?
Here is how the current code looks like:

<div style="background-color: transparent;">
<span style="background-color: darkblue; display: block; height: 1px; 
overflow: hidden; font-size: 1px; margin-left: 5px; margin-right: 0px; 
border-left-width: 0px; border-right-width: 0px; opacity: 0.75;"></span>

And here's how it is supposed to look like in order to have rounded 
corners in the layer selection div on all sides (set the right-margin to 
the same value as the left-margin):

<div style="background-color: transparent;">
<span style="background-color: darkblue; display: block; height: 1px; 
overflow: hidden; font-size: 1px; margin-left: 5px; margin-right: 5px; 
border-left-width: 0px; border-right-width: 0px; opacity: 0.75;"></span>

I am not quite sure where these divs are set - so that I can override them.

Hope somebody can shed light on these problems,

Regards,
Adrian

Hi,

Always be sure to mention the OL version you are using! Try to use the last
version of course. 

If you have a doubt about what the API offers to you and how it works,
please take your time to read the documentation: 
http://dev.openlayers.org/releases/OpenLayers-2.9.1/doc/apidocs/files/OpenLayers-js.html
http://dev.openlayers.org/releases/OpenLayers-2.9.1/doc/apidocs/files/OpenLayers-js.html 

Apparently you're trying to get the properties values before the object is
ready.. I can't know that for sure as I can't know how you've coded it but
taking a look at the events you are available to use won't hurt you. ;)

Cheers,

Gilberto Ramos

Shall I create manually the HTTP request with OpenLayers.Ajax.Request?

It is anyway weird that in the params section of the OpenLayers.Layer.WMS
object you can set LAYER, FORMAT, TRANSPARENT, etc. of the HTTP request, but
not BBOX, SRS, WIDTH, HEIGHT.

All of those parameters should come from your map - if you hard code
them into your request they won't change when you zoom in or pan the
map.

Antoni,

   Have a look at GeoMoose (http://www.geomoose.org/).  It uses Openlayers, with 
some additional Javascript to provide a "starter" mapping application.  It also 
(optionally) uses some PHP along with Mapserver's Mapscript to do some 
server-side processing.

Best Regards,
Brent Fraser

Ok Ian, right. (Thanks)
So you mean that you would download also data outside the viewport in
certain cases?

But, especially if the BBOX is small, this wouldn't be a huge problem. 
Or am I missing something?

If you want the BBOX to be exactly the visible part, use ratio 1 and
buffer 0 in the layer options.

So:

var layer = new OpenLayers.Layer.WMS(null, url, {layers: 'foo'},
{singleTile:true, buffer:0, ratio:1});

Best regards,
Bart

What server are you using?


    var layer = new OpenLayers.Layer.Vector("Guybrush Threepwood", {
        strategies: [new OpenLayers.Strategy.BBOX()],
        projection: new OpenLayers.Projection("EPSG:4326"),
        protocol: new OpenLayers.Protocol.WFS({
            version: "1.1.0",
            srsName: "EPSG:4326",
            url: "http://localhost:2006/GetFeature.ashx",
            featureType: "MonkeyIsland",
            schema:
"http://localhost:2006/GetFeature.ashx?service=MXP-WFS&request=GetSchema&schema=miwfs:MonkeyIsland",
            featureNS: "http://www.opengis.net/wfs",
            featurePrefix: "miwfs"
        })
    });


Replace the schema value for the correct Schema URL of your feature.. I'm
not sure at all about how you get the schema in your server as I'm use to
GeoServer only..! 

For example I'd have something like this as the schema:
http://localhost:2006/geoserver/wfs?service=wfs&version=1.1.0&request=DescribeFeatureType&typename=miwfs:MonkeyIsland

Hope helps you,

Good point Bart,
but I'd like to select a small portion of the map instead.

Putting a ratio<1 the layer would be reduced indeed, but centered with
respect to the viewport.
I'd rather specify where exactly to extract the data.

Mapfish client = GeoExt + Openlayers
GeoExt = ExtJS + Openlayers

I use Mapfish just as client! It has very nice widgets that would safe you a
couple of hours coding.. The result is the same you would obtain coding with
GeoExt because both use ExtJS (BTW, now 
http://www.sencha.com/blog/2010/06/14/ext-js-jqtouch-raphael-sencha/ Sencha
).

I think you have already looked at the 
http://demo.mapfish.org/mapfishsample/1.2/ Mapfish examples  but here's the
link anyway.

It is not complex at all! Just download the client and enjoy! =)

Hi Gilberto,

can I correct one point you made?

ExtJS is *not* called Sencha. The product name is unchanged.

The company behind the product has changed its name, that's all.

Best regards,
Bart

And you're totally right! Thanks for clarifying the matter..!

Summarizing, I think you can use all this frameworks together.. Just use
them if you really need them! Sometimes OL is all you need to create an
information product..

I don't know to which extent the client side of MapFish is now GeoExt.  
I suspect there are still MapFish only widgets.  MF folks : correct me 
if I'm wrong.

A lot of MF widgets (e.g. the layertree) are now obsolete in favor of 
their GeoExt replacement widgets.  I just don't know to which extent all 
the MF widgets have been replaced with/ported to GeoExt.  But the plan 
is to eliminate most of the client side of MF in favor of GeoExt.

Cheers,

Yves

I managed to find this (and fix my problem) for myself - by using 
beforefeatureremoved event:

markers.events.on({
         "featureselected": onMarkerSelect,
         "featureunselected": onMarkerUnselect,
         "visibilitychanged": onMarkerToggle,
         "beforefeatureremoved": onMarkerBeforeFeatureRemoved
     });

function onMarkerBeforeFeatureRemoved(evt){
     if(evt.feature.popup){
         //kill the popup
         map.removePopup(evt.feature.popup);
         evt.feature.popup.destroy();
         delete evt.feature.popup;
     }
}

Now, the popups no longer remain stuck if the layer refreshes...

Thanks!

Hi,

If you're using OL 2.9.1 you have plenty functions to access the data.. just
take a look at the OL Class Documentation for OpenLayers.Format.XML -> 
http://dev.openlayers.org/releases/OpenLayers-2.9.1/doc/apidocs/files/OpenLayers/Format/XML-js.html
http://dev.openlayers.org/releases/OpenLayers-2.9.1/doc/apidocs/files/OpenLayers/Format/XML-js.html 

If you're not using the lastest OL version, you should consider start using
it. =)

Regards,

Gilberto Ramos

Hi

I've updated my reques as you sugested. Now I'm having this error:

this.writers[prefix][local] is undefined
[Break on this error] var child=this.writers[prefix][local]....f(parent){parent.appendChild(child);} 
Openlayers.js (line 790)

At least is better than no error and no response :)

Thanks

Edu

What server are you using?


    var layer = new OpenLayers.Layer.Vector("Guybrush Threepwood", {
        strategies: [new OpenLayers.Strategy.BBOX()],
        projection: new OpenLayers.Projection("EPSG:4326"),
        protocol: new OpenLayers.Protocol.WFS({
            version: "1.1.0",
            srsName: "EPSG:4326",
            url: "http://localhost:2006/GetFeature.ashx",
            featureType: "MonkeyIsland",
            schema:
"http://localhost:2006/GetFeature.ashx?service=MXP-WFS&request=GetSchema&schema=miwfs:MonkeyIsland",
            featureNS: "http://www.opengis.net/wfs",
            featurePrefix: "miwfs"
        })
    });


Replace the schema value for the correct Schema URL of your feature.. I'm
not sure at all about how you get the schema in your server as I'm use to
GeoServer only..! 

For example I'd have something like this as the schema:
http://localhost:2006/geoserver/wfs?service=wfs&version=1.1.0&request=DescribeFeatureType&typename=miwfs:MonkeyIsland

Hope helps you,

Uhm... yes, I can see that you can specify the bounds of an Image layer.
But I don't have an URL of the raster (I'm trying to catch it without
success), I can retrieve it only via WMS.

I dont see how to figure that out, but I downloaded the latest's stable.
Anything that still does nto work I will just post a reply here. I know the
object is ready as some properties work and other seem not to be there.
Perhaps is was the version I was using as the js file size was not the same. 

Here is what is not clear at the moment. 

a) I can use move to set the new location but how to I get the location?

b)  how do I get the array of points (getVertices) from a feature? geometry
is a property but contain nothing ( its undefined ).

Actually with the OpenLayers.Layer.Image you download the WHOLE image then
you decide where to put it...
I'd like to exploit the WMS BBOX ability to extract portions of rasters...

Subject: [OpenLayers-Users] Noob question. I get my overlay when I have no
	base layer...
Message-ID: <F1D189FB-F289-4A1F-8182-1F292C493301@gmail.com>

I have the following code, which shows my overlay layer (news) when I take out the google layer, but doesn't show it when I leave the google layer in.  Have I done something wrong that should be obvious to me?  I assume it's either only loading the base layer or is layering them in the wrong order...

-- Jeff (code follows)

var map;
OpenLayers.ProxyHost = "/cgi-bin/proxy.cgi?url=";

function init() {

    map = new OpenLayers.Map('map');

    var gphy = new OpenLayers.Layer.Google("Google Physical",{type: google.maps.MapTypeId.TERRAIN}),
    var news = new OpenLayers.Layer.WMS("Renci News Stories", "http://descartes.renci.org:8080/geoserver/wms?SERVICE=WMS",
        {layers: "Renci_Internal:renci_communications",
         transparent: false,
         format: "image/png",
         srs: "EPSG:900913" },
        {isBaseLayer: false}
    );


    var hover = new OpenLayers.Control.WMSGetFeatureInfo({
                url: 'http://descartes.renci.org:8080/geoserver/gwc/service/wms?SERVICE=WMS',
                title: 'Identify features by clicking',
                layers: [news],
                hover: true,
                queryVisible: true
    });

    var showInfo = function(evt) {
            if (evt.features && evt.features.length) {
                for(var i in evt.features) {
                    alert("Story");
                }
            } else {
                $('responseText').innerHTML = evt.text;
            }
    }

    hover.events.register("getfeatureinfo", this, showInfo);
    map.addLayers([news,gphy]);
    alert(news.getFullRequestString());
    news.events.register("loadstarts",this,function() { alert("load started: "+ news.getFullRequestString()) });
    news.events.register("loadends", this, function() { alert("load ended") });

To make sure your features are already loaded when you call them, code within
the 'loadend' event function:

function functionName(event) {
    for (var i = 0; i < layer.features.length; i++){
        var featureGeom = layer.features[i].geometry;
        alert(featureGeom);
    }
}

layer.events.register("loadend", this, functionName);


You might have an idea with the example what you should do!

That seems to be exactly what you need to do, so that you can set your BBOX
completely unrelated to the current map's size or position.

Hi,

I tried to change the line "map.getLonLatFromPixel(event.xy)" to
"map.getLonLatFromPixel(ux,uy)"
It still don't work, I think because I want to show a popup without clicking
on the map. 
Otherwise I received xy from the users put in it. I think those codes are
processed when clicking on map.

How can I modify the code for receive the value xy from the users?


Thank you.

Arnaud,

I want to implement exactly the same thing in my project. I made a Ajax
request same as you with onSuccess function defined in the same JS file. The
problem for me is, the function defined for onSuccess event is not
recognized and the browser showing an error message saying that the function
is not defined.

I just don't know what's wrong with that function. I have my function
defined in the same file but is not recognized on  the request execution. Do
you have any experience with this issue or have any ideas on what's went
wrong ??

The excerpt from my XML request is as follows

searchAddress: function( e ){

         var swrequest = new OpenLayers.Ajax.Request(
 "http://siasporapv01:8080/gss/native?service=locate",
 { method: "GET", onSuccess: locateServiceResponse, extractAttributes: true
}
 );
 OpenLayers.Event.stop(e);
 },

locateServiceResponse: function(){

var xmlResponse = new OpenLayers.format.XML();
 console.log( xmlResponse );

},


Any help is appreciated.

Hello group,

Could some one share me their Tile Cache experiences please. I want

Hi,
The big advantage of tiling technologies is that you avoid data extraction
and rendering on the server side. This implies less server load and higher
performance. Disadvantages are that the tiles need to be pregenerated and
style is predefined. You can find more information here:
http://www.slideshare.net/cedricmoullet/tiling-state-of-the-art-2010
For the site http://map.geo.admin.ch/?lang=en, tiles have been generated for
about 50 layers. TileCache has been used and we didn't encounter any huge
problems with it (about 200 millions tiles generated).
Since WMTS is now a standard OGC implementation standard, I would consider
using it. Comparing to a TileCache tile structure, WMTS tile structure can
be seen as an URL redirection. And OpenLayers supports this new standard.
For example: http://map.geo.admin.ch/wmts.html
Hope this helps,
C?dric

Hi ...

I have the same problem like Edu.
But I have also a understanding problem. What is a featureNS? Why do I need
it?

My Layerdefinition is this:

	//VECTOR LAYER
	var wfs = new OpenLayers.Layer.Vector("WFS Vector Layer", {
        strategies: [new OpenLayers.Strategy.BBOX()],
        protocol: new OpenLayers.Protocol.WFS({
            url: "http://domain.com:8080/geoserver/wfs",
            featureType: "pcd_exportdata"
            featureNS: "http://domain.com:8080/geoserver/wfs"
        })
    });
    map.addLayer(wfs);

when I looking in the XML Response, then i can see all Point- data with all
feature.


Regards,
Robert.

Hi ...

I have the same problem like Edu.
But I have also a understanding problem. What is a featureNS? Why do I need
it?

My Layerdefinition is this:

	//VECTOR LAYER
	var wfs = new OpenLayers.Layer.Vector("WFS Vector Layer", {
        strategies: [new OpenLayers.Strategy.BBOX()],
        protocol: new OpenLayers.Protocol.WFS({
            url: "http://domain.com:8080/geoserver/wfs",
            featureType: "pcd_exportdata"
            featureNS: "http://domain.com:8080/geoserver/wfs"
        })
    });
    map.addLayer(wfs);

when I looking in the XML Response, then i can see all Point- data with all
feature.


Regards,
Robert.

Subject: [OpenLayers-Users] Noob question. I get my overlay when I have
	no base layer...

Well one thing I notice (may or may not be the reason), the option
isBaseLayer defaults to false according to the OpenLayers docs (
http://dev.openlayers.org/docs/files/OpenLayers/Layer-js.html#OpenLayers.Layer.isBaseLayer),
so that would mean that since you never explicitly state your google layer
to be your base layer by setting isBaseLayer to true, your map has no base
layer....perhaps the reason it works when there is only one layer is because
when there is only 1 layer, openlayers assumes that to be the base, but when
you have 2 layers, neither one set to base layer, it breaks.  Just a
thought, give it a try, I'm no pro though so it's really just an educated
guess.

I think I should describe with pictures.

http://osgeo-org.1803224.n2.nabble.com/file/n5307992/02.jpg 

In the popup you will see the numbers of the point, this point is contained
xy coordinate.
Question how can I show the rest of attribute data (like when you are
clicking on the map) from that point?

I'm using GeoServer+OL2.8


function popup_s(ux,uy)
                    {                                        
                    if (popup != null) {
                        popup.destroy();
                        popup = null;
                        }                                                            
                        var ux,uy;                    
                        popup = new OpenLayers.Popup.FramedCloud("chicken", 
                        new OpenLayers.LonLat(ux,uy),                         
                        null,                        
                        ux+","+uy,
                        null, 
                        true                    
                        );
                    map.addPopup(popup);
                    map.setCenter(new OpenLayers.LonLat(ux, uy), 2);
                }

Subject: [OpenLayers-Users] How to perform spatial search
Message-ID: <372666.21249.qm@web24308.mail.ird.yahoo.com>

Hi,
I am using OpenLayers for web mapping, GeoServer to serve maps as WMS and WFS & PostgreSql/PostGIS for database having spatial and non-spatial data.
I have cities & school data as point in their respective tables in the database which are publish through GeoServer. School table is linked with cities using cityID.
I want to develop a form that contains cities as text box and school as dropdown loaded from the database, so that a user can perform search on it and the map is zoomed to that particular area with non-spatial information display in a separate grid.
I don?t know how to load the data in the combo box / dropdown from the DB using the above software stack and perform some searching. How to zoom to a particular location based on the criteria and display non-spatial data in grid.
I need some guidelines or examples for the problem stated above.
Can somebody help me in achieving this?
Any help is appreciated.


Thank you,
--
Jehanzeb

HI,

I think you need to put in an html drop down list, you need to trigger a
function at an event occurent on this drop down list. Get the text and name
of layer, from which to search the feature from. The layer name should be in
drop down list. You need to programticaly generate a wfs with a cql filter
appended in the url . The response will contain the feature, you can get the
bounds of the feature, and simple use openlayers to zoom and pan to that
extent. I think you need to start looking for CQL filters, they will perform
the searching for you.

regards,
Imran

I think your previous post was closer to the more generalised question you
should be asking, more "How do I make a plugin for Sahana?"
That's a question to ask in 
https://lists.sourceforge.net/lists/listinfo/sahana-maindev

OpenLayers is just javascript ; if you want help making a webpage running a
map, yes this is the place to ask.

I would think you also wd want to look at Open Streetmaps for the map 
imagery- unless you're planning to stay with Google for that.  See

Hi

To solve the non calling issue, I've deployed the WFS and the Web application to the same server. Since they were in the same machine but in different ports it's necessary to setup the Openalyers.proxyHost, or make them work in the same Application Pool. I've done the latter and seen the (POST) request work, but not how I expected. My current request is:

var layer = new OpenLayers.Layer.Vector("MonkeyIsland", {
                strategies: [new OpenLayers.Strategy.BBOX()],
                projection: new OpenLayers.Projection("EPSG:4326"),
                protocol: new OpenLayers.Protocol.WFS({
                    version: "1.0.0",
                    srsName: "EPSG:4326",
                    url: "http://localhost/WFS/GetFeature.ashx",
                    featureNS: "http://www.mapinfo.com/wfs",
                    featureType: "MonkeyIsland",
                    geometryName: "VL_GMTR",
                    schema: "http://localhost/WFS/GetFeature.ashx?service=WFS&version=1.0.0&request=DescribeFeatureType&typename=miwfs:MonkeyIsland"
                })
            }
There are 2 things concerning this call:
1. I can only see the request being made (via Firebug) after I change the zoom level
2. The WFS response is: <ServiceException code="-1">Missing namespace prefix for PropertyName VL_GMTR</ServiceException>

So I believe that I'm missing one or more options in my request but, maybe a namespace, but I don't know how to set it...

Can someone help?

Answering Robert's question, I believe the featureNS is the namespace of the feature described in the WFS GetCapabilities. In my case I have the miwfs:MonkeyIsland feature, so the namespace prefix is miwfs and the corresponding namespace is identified in the root node of the GetCapabilities of the WFS (xmlns:miwfs="http://www.mapinfo.com/wfs").

Hi ...

I have the same problem like Edu.
But I have also a understanding problem. What is a featureNS? Why do I need
it?

My Layerdefinition is this:

	//VECTOR LAYER
	var wfs = new OpenLayers.Layer.Vector("WFS Vector Layer", {
        strategies: [new OpenLayers.Strategy.BBOX()],
        protocol: new OpenLayers.Protocol.WFS({
            url: "http://domain.com:8080/geoserver/wfs",
            featureType: "pcd_exportdata"
            featureNS: "http://domain.com:8080/geoserver/wfs"
        })
    });
    map.addLayer(wfs);

when I looking in the XML Response, then i can see all Point- data with all
feature.


Regards,
Robert.

Subject: [OpenLayers-Users] SphericalMercator and SRS aliases epsg:900913,
 epsg:3857, epsg:3785, epsg:102113
Message-ID: <4C44259B.1030800@geodan.nl>

  Hello list,

OpenStreetMap and also some popular commercial mapservices (google, 
bing, yahoo) are using the so called sphericalmercator projection.
OpenLayers has built-in support for this type of layer, inherited from 
OpenLayers.Layer.SphericalMercator.

If you use a sphericalmercator layer as a baselayer, you may want to 
combine this with other layers. By default,  the openlayers 
sphericalmercator baselayer uses SRS projection-code 'EPSG:900913' . So, 
if you try to open an overlay, the overlay layer will be called with 
parameter SRS=EPSG:900913.

EPSG Code 900913 happens to be a bogus code, based on the word 'google'. 
Perhaps due to the resemblance of '900913' and 'google' or due to other 
reasons, there are now several other codes in use for the same projection:
EPSG:3857
EPSG:3785 <= maybe because of a typo by someone somewhere?
EPSG:102113

Some map-services have stopped supporting SRS=EPSG:900913 and this 
raises a problem for openlayers sphericalmercator users. Instead of 
displaying a map, these mapservices will respond with something like 'no 
support for EPSG:900913'.

The problem of overlaying sphericalmercator layers that do not support 
epsg:900913 can be (partly) solved as follows:
Override the default srs code for sphericalmercator layers by explicitly 
resetting the projection before adding the layer to a map:

var osmLayer = new OpenLayers.Layer.OSM("OpenStreetMap"); // osmlayer is 
now sphericalmercator with default epsg:900913
osmLayer.projection = new OpenLayers.Projection ("EPSG:3857"); // 
osmlayer is now sphericalmercator with epsg:3857
map.addLayers ([osmLayer]);

Overlay layers will now be requested with SRS=ESPG:3857

However, resetting the code for the baselayer projection, causes trouble 
for the controls for MousePosition and MeasureControl: distances and 
coordinates are no longer presented in the correct projection.

I solved this by adding the following lines of code to file 
lib\OpenLayers\Layer\SphericalMercator.js
OpenLayers.Projection.addTransform("EPSG:4326", "EPSG:3857",
     OpenLayers.Layer.SphericalMercator.projectForward);
OpenLayers.Projection.addTransform("EPSG:4326", "EPSG:102113",
     OpenLayers.Layer.SphericalMercator.projectForward);
OpenLayers.Projection.addTransform("EPSG:4326", "EPSG:3785",
     OpenLayers.Layer.SphericalMercator.projectForward);

OpenLayers.Projection.addTransform("EPSG:3857", "EPSG:4326",
     OpenLayers.Layer.SphericalMercator.projectInverse);
OpenLayers.Projection.addTransform("EPSG:102113", "EPSG:4326",
     OpenLayers.Layer.SphericalMercator.projectInverse);
OpenLayers.Projection.addTransform("EPSG:3785", "EPSG:4326",
     OpenLayers.Layer.SphericalMercator.projectInverse);

Questions:
- is this the way to support aliases for 900913 and support 
MousePosition and MeasureControl at the same time?
- if yes, shouldn't the above lines be part of the standard OpenLayers 
distribution?

Hello

i'm having some trouble finding how to set the namespace for the geometry in
the WFS request.
My request is:

var layer = new OpenLayers.Layer.Vector("BootyIsland", {
                strategies: [new OpenLayers.Strategy.BBOX()],
                projection: new OpenLayers.Projection("EPSG:4326"),
                extractAttributes: false,
                protocol: new OpenLayers.Protocol.WFS({
                    version: "1.0.0",
                    srsName: "EPSG:4326",
                    url: "http://localhost/WFS/GetFeature.ashx",
                    featureNS: "http://www.mapinfo.com/wfs",
                    featureType: "BootyIsland",
                    featurePrefix: "miwfs",

                    schema:
"http://localhost/WFS/GetFeature.ashx?service=WFS&version=1.0.0&request=DescribeFeatureType&typename=BootyIsland"
                })
            }); 

but the response that I see in Firebug is:
<ServiceException code="-1">Missing namespace prefix for PropertyName
VL_GMTR</ServiceException>

How can I set the namespace prefix for the geometry?

Thanks in advance

Edu

  Hello Bart,

I am not sure if

http://trac.openlayers.org/ticket/2665

takes care of the side effect that Control.Measure and MousePosition are 
no longer working properly after resetting the projection code?

Subject: [OpenLayers-Users] Cluster strategy different styles
Message-ID: <AANLkTinBMwmTaREFOEZsQy4t409jR_BAwsE_8Wd8m_Cp@mail.gmail.com>

Hello all,

In my application I use a cluster strategy to aggregate my data.

 I would like to know if it's possible to use a specific style for :
    * the data they are not clustered
    * the data they are clustered

For example, here is the code I use actually :

   var vesselStyle = new OpenLayers.Style({
           'externalGraphic': '${iconURL}',
           'graphicHeight'  : 24,
           'graphicWidth'   : 24,
           'pointRadius'    : "${radius}"
       },{
           context: {
               'radius' : function(feature){

               }// EOF iconURL
           }// EOF context
       });// EOF vesselStyle


As you can see, I use a png for the feature that are not aggregated.
And I would like to draw a circle when the feature's count are more than one.

Do you think it's possible to mix two styles at the same time ?

Hi Anne,

check the example (first couple of lines in comments):

http://trac.openlayers.org/browser/trunk/openlayers/examples/web-mercator.js?rev=10384

So that's up to the application to provide (at least for now). But I can
also see that's not really easy for end-users.

What do other people think about providing the EPSG aliases by default in
the OL library?

Best regards,
Bart

  Hello Bart,

My 2 cents:
In my opinion it is quite difficult for users to discover:
- OpenStreetMap, Google, Bing, Yahoo etc. use a projection called 
'SphericalMercator'
- 'SphericalMercator' in OpenLayers uses code 'epsg:900913'
- there exist multiple aliases for 'epsg:900913' and some services 
prefer alias epsg:3857 or epsg:102113 over epsg:900913
- how to override the default openlayers sphericalmercator epsg code 
with an other epsg code
- discover that the override produces side effects in measurement and 
mouseposition (and other functions, such as click-events...?)
- how to solve the side effects, by adding code:
OpenLayers.Projection.addTransform("EPSG:4326", "EPSG:3857", 
OpenLayers.Layer.SphericalMercator.projectForward);
OpenLayers.Projection.addTransform("EPSG:3857", "EPSG:4326", 
OpenLayers.Layer.SphericalMercator.projectInverse);

But instead of solving this in the library, this can also be part of the 
documentation. Maybe that documentation already exists and I've 
overlooked it?

Cheers,

Anne

I think this is reasonably well documented in 
 
  http://docs.openlayers.org/library/spherical_mercator.html 

and if you search for:

 http://docs.openlayers.org/search.html?q=google+projection

You get that as one of the results. (Not as highly ranked as I would
like, I'll admit, but it is there.)

This being supported is something I'd question ;) Until very recently,
I'm pretty sure it was not at all possible to do this, so it's not really
a surprised that it isn't well documented, in my opinion.

No documentation like this exists at this time that I'm aware of.

Are you sure your featurePrefix is geoserver? Check your Workspace name in
GeoSever Admin; go to Layer Preview and see the corresponding Name for your
feature. Well, assuming the data you provide is ok you should change your
code to something like this: 

    var wfs = new OpenLayers.Layer.Vector("wfs", { 
        strategies: [new OpenLayers.Strategy.BBOX()],
        projection: new OpenLayers.Projection("EPSG:4326"),
        protocol: new OpenLayers.Protocol.WFS({
            version: "1.1.0",
            srsName: "EPSG:4326",
            url: "http://192.168.224.128:8080/geoserver/wfs", 
            featureType: "khasra", 
            featureNS: "http://192.168.224.128:8080/geoserver", 
            schema:
"http://192.168.224.128:8080/geoserver/wfs?service=wfs&version=1.1.0&request=DescribeFeatureType&typename=geoserver:khasra",
            featurePrefix: "geoserver"
        }) 
    });

  Thanks for pointing to this fairly complete documentation. However, 
the subject of why and how to use the epsg:900913 aliases and the 
caveats is not yet included. I've added a section "SphericalMercator and 
EPSG aliases" to http://trac.openlayers.org/wiki/SphericalMercator.

I don't think users can edit documentation such as

http://docs.openlayers.org/library/spherical_mercator.html

directly can they?

ok This does not make sense to me, and I hope its just me and not by
design...

I do somthing like this
			polygonFeature.style = {
                    pointRadius: "${type}", // sized according to type
attribute
                    fillColor: "#0000ff",
                    strokeColor: "#ff9933",
                    strokeWidth: 2,
                    graphicZIndex: 1
            };

and I can sent my color . but Doing this.

			polygonFeature.style = {
                    pointRadius: "${type}", // sized according to type
attribute
                    fillColor: "#0000ff",
//strokeColor: "#ff9933",
                    strokeWidth: 2,
                    graphicZIndex: 1
            };

will set the stroke to black. So its like I have to set all attributes each
time. Is there a way to just set one attribute, am I miss-using this?

I guess that whether you create your own styleMap, the values that you don't
explicitly set are then set to their default.
I think it's a standard way of working, but maybe I didn't get 100% your
intentions...

Hi all,

I set up a proxyhost for my WFS layers which were working fine without any
problems in OpenLayers application. I upgraded my GeoServer to the latest
version 2.0.2 and tested my application and everything seemed to be ok.
However, for some reason, my proxyhost is not working with the following
errors showing up in the log file or when I click on  WFS 1.0.0
(http://156.61.47.12:81/geoserver/ows?service=wfs&version=1.0.0&request=GetCapabilities
) link in my GeoSever home;

I am running the OpenLayers client application on windows 2003 with IIS and
GeoServer is being run from Apache server2.2 and Tomcat 5.5. In addition,
the OpenLayers homepage shows up when I test the proxyhost URL

Hi Anne,

the best way for documentation fixes/additions is to create a patch (svn diff or unified diff) on the rst document (available in svn) and create a Trac ticket with the patch attached. TIA.

Best regards,
Bart

Hi,

To change only some properties without repeating all others you can use

polygonFeature.style = new OpenLayers.Util.applyDefaults({pointRadius:20},
polygonFeature.style);

ok This does not make sense to me, and I hope its just me and not by
design...

I do somthing like this
			polygonFeature.style = {
                    pointRadius: "${type}", // sized according to type
attribute
                    fillColor: "#0000ff",
                    strokeColor: "#ff9933",
                    strokeWidth: 2,
                    graphicZIndex: 1
            };

and I can sent my color . but Doing this.

			polygonFeature.style = {
                    pointRadius: "${type}", // sized according to type
attribute
                    fillColor: "#0000ff",
//strokeColor: "#ff9933",
                    strokeWidth: 2,
                    graphicZIndex: 1
            };

will set the stroke to black. So its like I have to set all attributes each
time. Is there a way to just set one attribute, am I miss-using this?

Subject: [OpenLayers-Users] Empty Base Layer?
Message-ID: <AANLkTilKJwU-7A1VDYdeXzea24ewEOCDcahruN96NzFn@mail.gmail.com>

Hi,

I currently have a map that uses an OpenLayers.Layer.Image as the baselayer,
and then draws a bunch of vectors on top of it. However, the image in
question is simple enough that I'd really rather just do away with it and
use vectors for my background as well.

What's the best way to do this? I can make a dummy XYZ layer that just uses
blank gifs for all the tiles, but that seems like an enormous hack. What's a
simple way of specifying some bounds and a number of zoom levels, and just
having it be a blank baselayer?

Thanks,

Mike

You could just use a tile layer that always returns a blank image. Something
like this should work :

var vzl = new OpenLayers.Layer.TMS(
    'test', 'http://google.com',
    {
        getURL            : function(bounds){ return "
http://yourserver.com/blank.gif"; },
        buffer            : 0,
        isBaseLayer        : true,
        numZoomLevels    : 22,
        transitionEffect: 'resize'
    }
);
map.addLayers([vzl]);

Not sure if this falls into your hack category, but it's simply re-using an
existing layer type, so you don't have to create a new one.

good idea. AGS uses 102113 and I use an override to manage this 
projection issue. eg

             Ext.override(OpenLayers.Layer.WMS, {
                 getFullRequestString:function(newParams, altUrl) {
                     var projectionCode = this.map.getProjection();
                     if (this.url == null) isAGS ==0;
                     else var isAGS = this.url.search(/arcgis/);
                     if((projectionCode == 'EPSG:900913') && (isAGS >=0)) {
                         this.params.SRS = 'EPSG:102113';
                     } else {
                         this.params.SRS = (projectionCode == "none") ? 
null : projectionCode;
                     }

                     return 
OpenLayers.Layer.Grid.prototype.getFullRequestString.apply(

In both those cases I get global coordinates, though, don't I?

My Image layer is like so:

    baseLayer = new OpenLayers.Layer.Image( "Image",
    "/static/img/gridmap.png",
    new OpenLayers.Bounds(0, 0, 3, 3),
    new OpenLayers.Size(600, 600),
    {});

It's a 600x600 image, and the coordinate system of the map scales that from
0..3. Is there a straightforward way to get this effect with either of the
two above solutions?

Thanks.

What effect are you referring to? Why do you care to restrict the bounds of
the layer if you're just displaying blank tiles?

Well, I'm only displaying blank tiles on that layer, but there are a number
of items in the vector layer above?I would like to restrict the viewport to
the region containing these items.

Subject: [OpenLayers-Users] ArcGIS Online Cached tiles datum shift
Message-ID: <1279583586297-5314596.post@n2.nabble.com>


Hi,

Does anyone have the _exact_ proj4js definition for ESRI projections
EPSG:102100 and the older EPSG:102113?  

My maps have a y-coordinate shift (both north and south at different zooms)
off by many map pixels.  Always close, but no cigar. X-coordinate is always
dead on.  

I can add in ArcGIS online content as dynamic layer without any problems. 
But when adding cached tiles, there's always this shift.  Has anyone seen
this before and/or been able to resolve it?  I need to be able to use the
cached tiles.

I've used the one from spatialreference.org, as well as set it directly to
be equal to Google's EPSG:900913 but there's always a shift.  I've tried
many different variations with  +a and +rf and others but I feel like the
definition is missing a +towgs84=...  adjustment to properly correct for the
shift on the map but I have no way of knowing what those parameters should
be and whether it should be the 3-parameter adjustment or the 7-parameter
one.

Here's my current definition:  

Proj4js.defs["EPSG:102100"] = "+proj=merc +lon_0=0 +x_0=0 +y_0=0 +a=6378137
+b=6378137  +units=m +nadgrids=@null";

+towgs84=0,0,0,0,0,0,0  doesn't help, but I feel like the right values in
there will fix the problem.

Thank you,

-Vadim

When you intialize your map, pass it a "restrictedExtent" so that it will
only show your area of interest. See this example :

http://openlayers.org/dev/examples/restricted-extent.html

Also, it should be possible to use one of your vector layers as a basemap,
rather than creating a layer that does nothing.

Robert,

I've made good progress with your suggestion.  I created a new class
and just extended XYZ.js with the 2 methods you provided.  But I still
have a problem.

Old Code: locations where close, but kept jumping around north or
south of the right location

New code: locations are almost exactly 41.0 miles North of where they
should be. But they are off by a fixed amount.  So when I zoom in and
out they are staying put where they are, but they are still off.  So
if I try to put a point on the beach in Santa Monica, on the map it
looks to be between Santa Clarita and Palmdale.   As soon as I change
base maps to Google or a epsg:4326 map, all is well and points are in
perfect location.

So it's 1 step forward (locations don't jump) and 1 step back
(locations are pretty far north).

I read tileOrigin from the AGS layer spec, e.g.
http://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer.
 And I've made sure it is correct by testing in firebug and just
dumping out map.baseLayer.tileOrigin.

Did you do anything else to modify XYZ to make this work?  Does 41.0
miles mean anything?  to me it doesn't look like 1 degree, or anything
else.  But it's a fixed distance difference between plotted and viewed
points.  Some kind of error in calculation or my setup of the layer?

Thank you!

-Vadim

You might also keep in mind, that they are using arcgis.com now. Perhaps
some more info is there?

Ok, now I'm confused.  How do I initialize the ArcGISCache layer with
this service

http://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer

??

Previously I was going after

 http://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer
+ "/tile/" + "${z}/${y}/${x}"  tiles.

This goes after completely different scheme of tiles.

Hi Paul, what did you mean with that "the fourth paramter" ... ?

I set the transitionEffect to a Google base layer without success, no smooth
zoom/pan yet.

	        var gmap = new OpenLayers.Layer.Google(
	            "Google Streets", {
                          sphericalMercator: true, 
                          numZoomLevels:
OpenLayers.Layer.Google.MAX_ZOOM_LEVEL, 
                          transitionEffect: 'resize'
	        });

Any clue?
Piero

It seems it's not an OL feature for Google layers.
http://osgeo-org.1803224.n2.nabble.com/Zoom-effect-like-google-map-possible-td3898241.html#a3898393

OL developers: do you know if it will be an available feature for Google
Layers also, some day?

Thank you anyway.

Hi,

with the GMaps v2 API, we do not have smooth zooming in OpenLayers. If you use the GMaps v3 API (supported by OpenLayer trunk, see http://openlayers.org/blog/2010/07/10/google-maps-v3-for-openlayers/), you may have animated zooming, depending on your browser (e.g. Safari has it, Firefox does not - try http://www.openlayers.org/dev/examples/google-v3.html). But the GMaps API does not give us control over it. 

See (and vote for if you care) http://code.google.com/p/gmaps-api-issues/issues/detail?id=2011

Regards,
Andreas.

Hi Ian,
I am trying to apply your method.

I think I misunderstood something about it because in the end I get a
"OpenLayers.Control.AM_Navigation is not a constructor", as I create the
map.

I'm linked to the online OL library.
I have anyway a copy of it in my file system in ./OpenLayers dir: I copied
the OpenLayers.Control.Navigation class into a
./OpenLayers/Control/Navigation.js file, and then I created AM_Navigation.js
in the same directory.

I included ./OpenLayers/Control/AM_Navigation.js in my HTML page.

Do you guess where I did go wrong...?
Thank you in advance.
Piero

Sorry, I made a mistake in the javascript include.
It works.

You can also register a click handler, and stop the double click event from
propagating.

http://openlayers.org/dev/examples/click.html

Here is a quick example I modified from code :

OpenLayers.Control.Click = OpenLayers.Class(OpenLayers.Control,
{
    defaultHandlerOptions: {
        'single': true,
        'double': true,
        'pixelTolerance': 0,
        'stopSingle': false,
        'stopDouble': false
    },

    initialize: function(options) {
        this.handlerOptions = OpenLayers.Util.extend(
            {}, this.defaultHandlerOptions
        );
        OpenLayers.Control.prototype.initialize.apply(
            this, arguments
        );
        this.handler = new OpenLayers.Handler.Click(
            this, {
                'dblclick': function(e){
                    this.handler.stopDouble = true;
                }
            }, this.handlerOptions
        );
    }
});

Ok almost there?

this.style = new OpenLayers.Util.applyDefaults(
{fillColor:"#"+color},
{fillOpacity:a},
this.style);

then later

this.style = new OpenLayers.Util.applyDefaults(
{strokeOpacity:a},
this.style);

This works but using this 

this.style = new OpenLayers.Util.applyDefaults(
{strokeColor:"#"+color},
{strokeOpacity:a},
this.style);

turns it all black. The strokeColor seems not to work.

Message-ID: <227907.65401.qm@web55904.mail.re3.yahoo.com>

Hi,

I am new to openlayers and wondering if there is any tool(s) to pre-generate a 
bbox attributes for all features to make queries faster. 


Thanks,
Ravi.

Subject: [OpenLayers-Users] How to use Other Projections in a stand alone
	client side environment
Message-ID: <AANLkTiliGLKuu6P6HReZdNCGfLYclZwtG2iGTgnR1Ese@mail.gmail.com>

Hello All, I recently came across, the site
http://spatialreference.org/ref/epsg/24378/  which can show coordinates of
projection EPSG:24378 once we click on the map, I am interested to put the
same functionality on my locally hosted html file and perform the coordinate
calculation client side, i.e no server side calculations from
http://spatialreference.org   . The code referred was map.js in the HTML
file which is as follows:

function init(code) {
    m = new OpenLayers.Map('map', {'maxResolution': 360/512});
    m.addLayer(new OpenLayers.Layer.WMS('',
'http://labs.metacarta.com/wms-c/Basic.py', {'layers':'basic'}));
    m.addLayer(new OpenLayers.Layer.Markers(''));
    m.zoomToMaxExtent();
    m.marker = new OpenLayers.Marker(new OpenLayers.LonLat(0,0));
    m.layers[1].addMarker(m.marker);
    if (window.bounds) {
    m.addLayer(new OpenLayers.Layer.Boxes());
    m.layers[2].addMarker(new OpenLayers.Marker.Box(bounds));
    }
    m.events.register('moveend', m, function() {
        var c = this.getCenter();
        this.marker.moveTo(this.getLayerPxFromLonLat(c));
        document.getElementById("out").innerHTML = "Waiting...";
        document.getElementById("in").innerHTML = [c.lon,c.lat].join(", ");
        var json = '{"type":"Feature", "geometry":{"type":"Point",
"coordinates":[' + c.lon + ', '+ c.lat + ']},"properties":{}}';
        var s = document.createElement("script");
        s.src = "/projection/?json=" + escape(json) +
"&inref=EPSG:4326&outref="+code+"&callback=project_out"
        document.body.appendChild(s);
    });
    if (window.bounds) {
        m.setCenter(bounds.getCenterLonLat());
    } else {
        m.zoomToMaxExtent();
    }
}
function project_out(data) {
    if (data.coordinates) {
      document.getElementById("out").innerHTML = data.coordinates.join(", ");
    } else if (data.error) {
        if (window.console) {
            console.log(data.error);
        }
        document.getElementById('out').innerHTML = 'An error occurred.';
    }
}

while the html only has following script:

var bounds = new OpenLayers.Bounds(70.329999999999998, 28.0,
97.450000000000003, 35.549999999999997);

defining bounds of this specific projection:

How can i use this code locally, i want to place it in e.g examples
folder of OL 2.9 source, and make it work, but the projection
information is missing which is as follows in WKT:
PROJCS["Kalianpur 1975 / India zone I",
    GEOGCS["Kalianpur 1975",
        DATUM["Kalianpur_1975",
            SPHEROID["Everest 1830 (1975 Definition)",6377299.151,300.8017255,
                AUTHORITY["EPSG","7045"]],
            TOWGS84[295,736,257,0,0,0,0],
            AUTHORITY["EPSG","6146"]],
        PRIMEM["Greenwich",0,
            AUTHORITY["EPSG","8901"]],
        UNIT["degree",0.01745329251994328,
            AUTHORITY["EPSG","9122"]],
        AUTHORITY["EPSG","4146"]],
    UNIT["metre",1,
        AUTHORITY["EPSG","9001"]],
    PROJECTION["Lambert_Conformal_Conic_1SP"],
    PARAMETER["latitude_of_origin",32.5],
    PARAMETER["central_meridian",68],
    PARAMETER["scale_factor",0.99878641],
    PARAMETER["false_easting",2743195.5],
    PARAMETER["false_northing",914398.5],
    AUTHORITY["EPSG","24378"],
    AXIS["Easting",EAST],
    AXIS["Northing",NORTH]]
.

Any help or source code will be highly appreciated.

OpenLayers is set up to use Proj4js internally which will do the 
coordinate conversion for you on the client side.. Have a look at 
http://trac.osgeo.org/proj4js/

                projection: new OpenLayers.Projection("EPSG:4326"),
                protocol: wfsProtocol
            });

map.addLayer(layer);
layer.refresh({ force: true });

The response of the request is:

I'm starting to believe that this error has something to do with the fact
that VL_GMTR is a complex type.

Can you help me, please?

Subject: [OpenLayers-Users] Don't want two Control.Panel activate in the
	same time
Message-ID: <397830.26849.qm@web114409.mail.gq1.yahoo.com>

Hi,

I have a map with two Control.Panel and I don't want  that two control  can be 
activate in the same time
For example when I click on the control_A in the Panel_1, I want that all  the 
controls of the Panel_2 be deactivate.

I search on Internet and don't find a solution. I try to use the onClick 
function of Control.Panel but without success.
So if someone have an idea or at less can explain me how the onClick function 
work, it's will be great

Thank you

Beno?t

Hi,

instead {fillColor:"#"+color}, {fillOpacity:a}
You should use
{fillColor:"#"+color, fillOpacity:a}

new OpenLayers.Util.applyDefaults.(arg1, arg2) is the correct use

arg1 and arg2 are something like {property1:value1, property2:value2)

Ok almost there?

this.style = new OpenLayers.Util.applyDefaults( {fillColor:"#"+color},
{fillOpacity:a}, this.style);

then later

this.style = new OpenLayers.Util.applyDefaults( {strokeOpacity:a},
this.style);

This works but using this 

this.style = new OpenLayers.Util.applyDefaults( {strokeColor:"#"+color},
{strokeOpacity:a}, this.style);

turns it all black. The strokeColor seems not to work.

Subject: [OpenLayers-Users] Override 'click' event of RegularPolygon handler
Message-ID: <1279648295628-5317744.post@n2.nabble.com>


Hi all,
I was trying to personalize the behaviout of my DrawFeature control, but I
can't find the function defining the 'click' trigger in the RegularPolygon
handler.

I tried to define separately an OpenLayers.Control.Click
(http://openlayers.org/dev/examples/click.html) but it's not working
whenever a OpenLayers.Control.DrawFeature is set.

I tried to override the OpenLayers.Handler.Drag.click function (the
RegularPolygon handler descends from it), but it seems the click function is
never called by the RegularPolygon handler.

Any suggestion?
Thank you for reading.
Piero

Well I know it loaded, I can seem them. I have my code in button events. But
I do know what your are saying. Still I can find the functions pr properties
to get the info I need( see above ). I'm sure there is a good reason for
this, but normally you have get and set function for this kind of stuff. 

add a doohickey. 
doohickey.dothis()
doohickey.setthis()
doohickey.getthis()

At least that is normally what SDK's do, I'm sure its just me.

Subject: [OpenLayers-Users] IE8 not showing the move cursor during pan
Message-ID: <4C4605CC.4030405@telenium.ca>

In the website[1] I'm working on right now, whenever you pan the map your cursor
will change to the "move" cursor (four arrows) if you're using IE6, Chrome, or
Firefox. Unfortunately, the cursor does not change if you're using IE8. I expect
this is a problem with my JavaScript, since when using IE8 on OpenStreetMap.org
the mouse cursor changes properly during a pan.

I've made sure that the theme files and the OpenLayers.js are the most recent
stable versions (2.9.1). I've also tried turning off all the SelectFeature
controls just in case there was some interaction, but it didn't help.

Any assistance would be appreciated.

This method worked perfectly, thanks very much. I used maxExtent and
maxResolution to set my desired limits.

Message-ID: <3F643797A078EB4FB02880080968098402050319@langouste.zhaw.ch>

Hello list,

I try to show a legend for my base WMS layer. But I don't know how to realsie it. Is there a possibility in OpenLayers to show a legend in a div?
I want to have a legend like this:

0 - 0.5
>0.5 - 1
>1 - 2
>2 - 3
>3 - 4

I know the GetLegendGraphic Parameter for WMS, but if I use this my legend always looks like this:

0 - 0.5
0.5 - 1
1 - 2
2 - 3
3 - 4

But with this you don't know which is the class for 0.5. Is there a dynamic way to create the legend, My data is in an postgres database and I use UMN Mapserver for the WMS.

Thank you
Hanno

Correct, this would have to be done via patches.

I have integrated your changes into the main documentation:

Hello Group,

I want to change the map bounds dynamically based on the user selected
object bounds from a form. This  bounds change should not affect the
maxExtent of the Map so that the user is further allowed to zoom out from
the dynamically set bounds. In one line , How do I make my current map zoom
to the bounds I have while retaining the same maxExtent bounds.

I am sorry, I am new to OpenLayers and a beginner in Java Script.

What is mzp here ??  Is it a class like OpenLayers or a function in
OpenLayers ?

Hello Kalyan,

this is an object/instance from the map-class "OpenLayers.Map".

Hello list,

I have a Layerswitcher in my OpenLayers Map. But in this LayerSwicther div is the title "overlays". I want to show the LayerSwicther without this title. Is it possible? How can I delete this title?

Hi,

I think you have to change your .css (or.js) file. Do a search for "overlays".

Hey Hanno,

check the function "loadContents" in LayerSwitcher.js . There is a div "this.dataLbl = document.createElement("div");". This will be added to DOM in this function (2 X this.layersDiv.appendChild(this.dataLbl); ). Removing this line/s will solve this problem. You should create an own class which inherits from LayerSwitcher and overwrite the loadContens-function.

Another solution is to use localisation and change the value for the key 'overlays'.

Message-ID: <AAD98904A979004F8FD29D8368C6463846F0EC@SERVER-MAIL.le34.dk>

Hi everybody.

 

 

In OpenLayers 2.9.1 my map options is defined with a maxResolution,
minResolution and a MaxExtent like below:

 

var mapOptions = 

{

    projection: 'EPSG:25832',

    units: 'm',

    maxExtent: new OpenLayers.Bounds(100000,6000000,1000000,6500000),

    minResolution: '0.125',

    maxResolution: '768',

    restrictedExtent: new
OpenLayers.Bounds(100000,6000000,1000000,6500000),

    controls: 

    [

    ]

};

 

This works fine in OpenLayers 2.9.1 but doesn't work with the nightly
build (version 19-07-2010 and 14-06-2010)

In the nightly build I get this error in firebug when adding the first
layer to the map:

this.resolutions is undefined: zoom = Math.max(0, Math.min(zoom,
this.resolutions.length - 1)); (Layer.js (line 1061))

 

 

When I define the resolutions in my map options like below the map works
fine again:

 

var mapOptions = 

{

    projection: 'EPSG:25832',

    units: 'm',

    maxExtent: new OpenLayers.Bounds(100000,6000000,1000000,6500000),

    minResolution: '0.125',

    maxResolution: '768',

    restrictedExtent: new
OpenLayers.Bounds(100000,6000000,1000000,6500000),

    resolutions: [768, 384, 192, 96, 48, 24, 12, 6, 3, 1.5, 0.75, 0.375,
0.185],

    controls: 

    [

    ]

};

 

I can see that there are some issues with the resolutions: 

http://trac.openlayers.org/ticket/2427

 

My question is now do I always need to add the resolutions in map
options or can I use maxResolution, minResolution and a MaxExtent?

Hi all,
I've been reading about different ways on how to override an existing
method.
That are, e.g.:

* OpenLayer.Control.myControl = OpenLayers.Class.create();
* OpenLayers.Control.myControl.prototype = OpenLayers.Class.inherit(
OpenLayers.Control.Navigation, {
*
*     defaultDblClick: function (evt) {
*         // ...my defaultDblClick overridden code...
*     },
*
*     CLASS_NAME: "OpenLayers.Control.myNavigation"
* });

Or simply:

* OpenLayers.Control.myControl =
OpenLayers.Class(OpenLayers.Control.Navigation, {
*
*     defaultDblClick: function (evt) {
*         // ...my defaultDblClick overridden code...
*     }})

Is there any difference between these methods?
I would really appreciate an explanation, thank you so much.
Piero

Hi again. 

 

I just found a solution to my problem.  The Layer.initResolutions has been rewritten in the nightly build and now it checks if maxResolution and minResolution is a number. So when I remove the quotation marks from maxResolution and minResolution in my map options like below the map works fine again:

 

var mapOptions = 

{

    projection: 'EPSG:25832',

    units: 'm',

    maxExtent: new OpenLayers.Bounds(100000,6000000,1000000,6500000),

    minResolution: 0.125,

    maxResolution: 768,

    restrictedExtent: new OpenLayers.Bounds(100000,6000000,1000000,6500000),

    controls: 

    [

    ]

};

 

maxResolution and minResolution can be set to 'auto' so I assumed it could only be a string. My mistake...

Subject: [OpenLayers-Users] Draggable (Gunsight) Control?
Message-ID: <AANLkTilh5E2rifH3uYQfran7exrD8G9KtGzn2gVmcRzt@mail.gmail.com>

Hi All,

I have a unique requirement that I need help with. Perhaps this is something
new...

The best way to describe it is to look at this:
http://www.youtube.com/watch?v=sXotq-W5HmA&feature=channel  but the gunsight
is not always in the center, you can drag it around in the map viewport.

So,
+ I need a Gunsight control (which uses Map.getLonLatFromPixel() to work out
the geographical focus of where the gun is pointing).
+ The Gunsight does not move when the map is panned/moved (it's tied to
pixel position - not geographical)
+ The Gunsight needs to be draggable within the map view port <div> (can't
drag outside the viewport) a non-draggable/fixed pixel position solution
(i.e. center of map viewport) would be an unacceptable.


Thanks && Cheers :)

Well, the fact that you need this does not mean that anyone here is entiteled to make it for you..

I think a good starting point could be looking at the OverviewMap control, which uses a div placed on top of the map, and then make a control yourself based on somewhat the same concept.

Good luck!



	Thanks && Cheers :)

So, should my call be like

OpenLayers.map.mzp.zoomToExtent(new OpenLayers.Bounds(left, bottom, right,
top));

"mzp" is a typing error and means the map-object. You have to call "map.zoomToExtent(new OpenLayers.Bounds(left, bottom, right, top));"

My goodness.

It's a typo error in Christopher's mail

mzp.zoomToExtent(new OpenLayers.Bounds(left, bottom, right, top));

I was thinking that there's another class of MZP :)

I think, I now can use it.

I would have thought that draggable markers would be a better place to start
than the overview. This is very similar identical to a draggable marker
except it doesn't pan/follow the map.

Well, I guess both approaches could work, but markers (or vector features) is rather closely tided to moving with the map, and you then would have to override a lot of that behaviour..

Subject: [OpenLayers-Users] Rule Filter and Context
Message-ID: <AANLkTilLLazUV7MQLlgIpSsx7ID65rZ5qOP6afVrjfMr@mail.gmail.com>

Hi All,

I'm trying to use a Rule with an context object.
The rule without the context object works fine. But each time I try to
define a context the rule is no more applies.
Do you know what I am doing wrong ?

Here is my code. In this one I would like to apply a specific style
when the features are clustered and a normal style when they are not.

var oStyle = new OpenLayers.Style();

var oStyleMap = new OpenLayers.StyleMap({
            "default": oStyle
});

var ctx = {
    'radius' :function(feature){
        console.log(oStyle);
        if (feature.attributes.count>1){
            return Math.min(feature.attributes.count,7) + 4;
        }
    }
};
var noCluster = new OpenLayers.Rule({
    elseFilter: true,
    filter: new OpenLayers.Filter.Comparison({
      type: OpenLayers.Filter.Comparison.EQUAL_TO,
      property: "count",
      value: 1
    }),
    symbolizer: {pointRadius: '3', fillColor: "red",
               fillOpacity: 0.7, strokeColor: "black"}
});

 var cluster = new OpenLayers.Rule({
    context : ctx,
    elseFilter: true,
    filter: new OpenLayers.Filter.Comparison({
      type: OpenLayers.Filter.Comparison.GREATER_THAN,
      property: "count",
      value: 1
    }),
    symbolizer: {pointRadius: '${radius}', fillColor: "green",
               fillOpacity: 0.7, strokeColor: "black"}
});


oStyle.addRules([noCluster, cluster]);


var vessels =   new OpenLayers.Layer.Vector("vessels", {
                        strategies:[
                           new OpenLayers.Strategy.Cluster()
                        ],
                        styleMap: oStyleMap
                });

Thanks your help.

Message-ID: <5994f17510572c8a109c9c0b5957a701.squirrel@mail.peterse-uithuizen.com>

Hello all,

it looks like I have a problem with loading tiles. When I change my zoom
level, I see (with firebug) tiles being downloaded which I can't see
direct on my screen.
My TMS options are:
 { type:'jpg',
   getURL:get_osm_url,
   border:0,
   transitionEffect: 'resize',
   projection:new OpenLayers.Projection("EPSG:28992")
 }

Am I right that the option border mean that tiles which are out of my
window shouldend be downloaded jet?

An other question is, how can I enable caching the downloaded tiles?

Thanks for your help.

Regards,
Peter.

I am using a vector layer to highlight certain areas on a mapping application of I've created.  Each click resets the protocol url to a new location and refreshes the layer, pulling down a new feature (in GML, from GeoServer).

I'm having a strange issue - one of those GML files being pulled down by the vector layer is very large (800K).  When I'm zoomed way into the map, the vector layer doesn't highlight - whereas the smaller areas (smaller gml files...around 70K) around it highlight without issue.  So I'm not sure what's going on - I was using the GML (deprecated) layer, but I switched over to the Vector layer and I'm seeing the same issue.  Does anyone have any ideas?  I don't think my code will be particularly helpful, but I'll include it anyway....

  Creating the layer...

            gmlLayer = new OpenLayers.Layer.Vector( "GML", {strategies: [new OpenLayers.Strategy.Fixed()],
                protocol: new OpenLayers.Protocol.HTTP({
                    url: "ajax/ajaxProxy.cfm?proxyURL=http%3A%2F%2Fmywebsite.com%3A8080%2Fgeoserver%2Fwfs%3Frequest%3Dgetfeature%26service%3Dwfs%26version%3D1.0.0%26srsname%3Depsg%3A900913%26typename%3Dpg_service_area%26filter%3D%3Cogc%3AFilter%20%20xmlns%3Aogc%3D%22http%3A%2F%2Fogc.org%22%3E%3Cogc%3AFeatureId%20fid%3D%22service_area.12342%22%2F%3E%3C%2Fogc%3AFilter%3E",
                    format: new OpenLayers.Format.GML()
                })
            });

Each time a click occurs, a new url is passed in.  I've verified that the URL for the large GML file returns a valid GML file.  There's nothing particularly strange about it.

    setUrl = function(url){
        gmlLayer.protocol.options.url = url;
        gmlLayer.refresh();
    };

Let me know if there's anything else that would be particularly diagnostically helpful.

Message-ID: <AANLkTin7Xm8zxAKs0Nd6RMYbTqP-mQ3RVoN-35uXHQ-0@mail.gmail.com>

Hello everyone,

I have defined 2 layers on OpenLayers map. One as a base layers and the
other as a normal layer with 'background' parameter set to 'transparent' in
it's request. When I open the map in Chrome, I could see the normal layer on
top of Baselayer ( transparent).But, when I open it in Internet explorer,
the normal layer is hiding base layer. Is it a bug with IE ? Is there
someone experienced similar problem or any suggestions ??

Thanks,

Peter,

you are looking for buffer: 0 and ratio: 1 in the layer options. There is no border option. Check the API docs for details.

Bart

Yes. My image_format is 'PNG' and I am using IE 8.

Here is how my request looks

It's working perfect with Chrome. Some how IE is not able to show
transparent tiles

Hello,

I am trying to understand how the SVG renderer works.
What I am not understanding is that there is SVG inline even if my webpage
is declared has HTML and not XHTML.
I am not able to understand how this is possible.

I am looking to that, because in the same time I try to use a clipPath
between two polygons in the SVG render of a layer.
Even if I add a valid SVG, nothing is displayed.

If someone can help me

Hi.
Is geoserver and your webpage in different domains? if Yes? then are
you request wfs response in XML format (e.g) GML, if Yes? then it will
not work because XML data can only be retreived through same domanin.
This is called SOP , same origin policy that all browsers follow, if
your page came from www.abc.com it cannot post xmlhttp request to
www.xyz.com .. in your case you should use JSON

Imran

Register a listener for the "changelayer" event on the map I guess is what you want.

Something along the lines of

map.events.register("changelayer", this, changelayer);

function changelayer(evt){  
    if(evt.property == "visibility" && evt.layer.getVisibility()){
        console.log("layer " + evt.layer.name + " activated");
    }
    
}


hope this helps you along

Hi Imran/All,

Thanks for your response,

Just for your more clarity, I have a setup like this:

internal ip1 --- geoserver running
i am behind a proxy .. at proxy server apache is running at proxy server i
have added reverse proxy for geoserver

http://mydomain.com/geoserver     internal ip1

WMS request for geoserver inside the proxy is working fine but whenever i
query for getfeature info it is not giving the result .....
i.e. the request  www.someDomain.com/geoserver  is displaying the map from
inside the proxy but not giving the feature info on clicking . ALso it is
not showing any error in firefox error console ..
>From certain forum I got to know that we should add PROXY_BASE_URL in our
web.xml ... I tried adding it but still no result..

Also I have another problem ....when i open  www,.somedomain.com/geoserver
from outside the proxy ... the WMS request also stops working...

So in this case, are they 2 from different domains?
Will json be helpfull in this case?

Regards,
M. Rizwan Khan

Hello Bart,

thank you very much.
buffer:0 helps to minimize the number of tiles which will be downloaded.

Regards,
Peter.

Try requesting the image in gif format and see if transparency works in IE.

Message-ID: <AANLkTikcPRK-oYe1nXPydiAAqxAdrqSXZfYEnFVsrM9L@mail.gmail.com>

Hi all,

I was wondering if there is a way to manually select a feature, i.e. when a
feature is clicked, I want to select a feature next to it as well.
I can't seem to find any documentation on this, unfortunately.

Thanks,

Alex.

You can use:

OpenLayers.Layer.Vector.getFeatureById()

or the undocumented/private/I can't find it in the api docs

OpenLayers.Layer.Vector.selectedFeatures array.

Hi,

There's a rather long and recent thread you might be interested in on 
the OSGeo-discuss mailing list : Drupal GEO mailing list proposal.  I 
suspect that would be a good place to look for info on the use of OL in 
Drupal.

HTH,

Yves

Then I recommend doing more research into how browsers work. :)

I'm not sure I understand what you're doing. Can you share
the OpenLayers JavaScript you are attempting to use?

Is there any way to make this work with the /rest/... URL?

I took the code you (Robert) provided from ArcGISCache and changed how
it was generating the URL.  not calculating, that is left in place,
but generating - and I just removed all the "L" and "R" prefixing, and
padding with 0's and so on.  And made that work with the /tile/z/x/y
scheme, but tiles are still mis-aligned.

Do you know of any efforts to make ArcGIS tile/cached services work on
top of XYZ.js with the /rest/... URL.

Thank you,

-Vadim

Message-ID: <201007221858.40417.mgleahy@alumni.uwaterloo.ca>

Hello list,

I'm taking a look at OpenLayers again, and I'm just trying to figure out how to 
effectively capture various mouse events.  Based on the examples provided, it's 
fairly straightforward to get click and double-click events.  But I don't seem 
to be able to figure out how to handle the right click event, or 
mouseup/mousedown events.

I've tried cobbling together a sample...and although I seem to be able to make 
something happen with mouseup and mousedown, these end up appearing as 'click' 
events.  As for a right-click event, I can't seem to capture that at all.  I'm 
sure this can be done, but I just don't understand the OpenLayers classes well 
enough to implement it.  Can someone look at the attached html file and 
identify where I'm going wrong?  If you drop it into the examples of the dev 
version of OpenLayers, it should work (at least in FireFox), and it'll write 
messages into a Firebug console.

Mike

Message-ID: <E9C5DB35C2B612479A61E70C3D9DEA8E062F6C2B@TEAM.idir.bcgov>

Hi,
	I'm trying to create an editable map based upon the OpenLayers
wfs-protocol-transactions example. On some occasions (for example when
other users have updated features) I want to abandon the outstanding
edit on a feature and redraw it as it was originally obtained from the
base WFS service. I couldn't work out how to do that and have reverted
to trying to redraw the entire layer using the layer.redraw and
layer.refresh functions. Unfortunately nothing seems to work. The
features stay as drawn, which no longer matches what is in the geoserver
service. How do I do some equivalent of "undo this feature and cancel
any pending changes on it", or alternatively "refresh this feater (or if
necessary all features) from the WFS service.  The code fragment I have
at this point is:
   
    var saveStrategy = new OpenLayers.Strategy.Save
	({
		onCommit: function(response)
		{			
			if (response.success())
			{
				alert("Good");			
				alert(response.priv.responseText);
			} else 	{
				alert("Bad");				
				alert(response.priv.responseText);

			} 
			if (confirm("Do you want to abort this request
?"))
			{
				alert("Abort request here");
				this.layer.refresh(true);
				this.layer.redraw();

			}			
		}
	});		
 
    wfs = new OpenLayers.Layer.Vector("Editable Features", {
        strategies: [new OpenLayers.Strategy.BBOX(), saveStrategy],
  	
  	
  	AND SO ON...

	Any Suggestions ?

Not sure how OpenLayers handles it, but fir html, how  about 
onContextMenu event? For mouse handling, I am pretty sure you can only 
reliably pick right button in onMousedown event

That does work for right-click, although it's not as tidy.  What confuses me 
is that it would seem that based on the documentation that there are specific 
functions meant for handling these events in the click handler class:  
http://dev.openlayers.org/docs/files/OpenLayers/Handler/Click-js.html

Am I misinterpreting that?

My Web Service doesn't accept 'gif' value for image format. However, it
accepts another parameter called 'image_transparency' with values of either
'rgb' or 'argb'. Setting it to 'argb' solved the problem. Now, the
transparency of the outer layers working perfect with IE.

Now the problem is solved.

Thank you all for your responses.

Cheers,
Kalyan

My apologies. By mistake I hit enter and it sent out with incomplete details

In my previous mail, it complains G_SATELLITE_MAP is not an object.

Could some one suggest me on how to use google satellite or other layers in
Open Layers please.

Ok...a bit more on this.

I am able to capture right clicks by disabling the contextmenu action, then 
checking for the right-click event on mouseup.

map.div.oncontextmenu = function(){return false;};
map.div.onmouseup = function(e){
	if (OpenLayers.Event.isRightClick(e)){
		alert("Right button click"); // Do stuff here...
	}
};

From here, though, I'd want to get the event variable 'e' to have the various 
properties that are normally prepared through OpenLayers events (e.g., to have 
the 'xy' property).  Can anyone recommend a better way to do this?  Is there a 
problem with taking over the mouseup event on the map div?  If so, what other 
approach might work here (e.g., would using jQuery to bind events work 
better)?

Regards,
Mike

Hello,

It seems to me that you're not checking the problem where you're 
supposed to.
onCommit returns the reply from the server, so it's the server's job to 
accept or reject the changes. If the server rejects the changes, you can 
do just this.layer.refresh({force: true}); and you will get the old data 
(and the new data will be discarded).

Good luck

Subject: [OpenLayers-Users] Help with changing the color of drawn features ?
Message-ID: <1279870697665-5328663.post@n2.nabble.com>


Hello everyone, I am currently teaching myself OpenLayers and managed to draw
Polygons, dots and lines so far. -Along with styling- What I have a hard
time figuring out is, is there a way to select the color we want to draw
these figures in ? I mean, I have set an HTML Option menu that has some
colors and selecting one will help me draw the features in that color but I
haven't been able to come up with a way despite tinkering with styles for
the past 2 days. If there's anyone who can help me out with this, I would be
grateful. Thanks.

Cheers,
Koveras

Well, regarding the mouse 'clicks' you should take a look at the source of
this example:
http://openlayers.org/dev/examples/click-handler.html
It's something about defining a class OpenLayers.Control.Click inheriting
from OpenLayers.Control, then defining the click Handlers.

Whether you'd like instead to manage mouse moves you can just register the
event, e.g.
myMap.events.register('mousemove', this, MouseMove);
where myMap is your OpenLayers.Map and MouseMove is your own function that
is called at every mouse movement.

Take a look here for the supported event types (of a map):
http://dev.openlayers.org/apidocs/files/OpenLayers/Map-js.html#OpenLayers.Map.EVENT_TYPES

I'm not OL expert so I don't give 100% certainty that these are the best
ways to go... they worked for me!

Hi Koveras, have you tried:

var myFeatures = new OpenLayers.Layer.Vector("myVectors", {
			styleMap: myStyleMap,
                        strategies: [myStrategy],
                        protocol: etc.....
}

Then:

var myStyleMap = new OpenLayers.StyleMap({
			new OpenLayers.Style({
				fillColor: '${color}',
				strokeColor: '${color}',
				[...]
			}, {
				context: {
					color: function(feature) {
						// Here define your JS function that picks the color from the HMTL
element?
						[...]
						return selectedColor;
						}
                                }
});

Could this be?
Piero

Hello Piero, many thanks for your reply. I implemented the code you gave me
-only applied the styles so far, leaving the strategy for the defaults-
however, the HTML part can't reach the function since it is wrenched in the
init() part that sets up the map. And when I move the vector and the styling
-along with the function- outside the init() part -actually, when I move it
right under the <script type=text/javascript>, this time the compiler tells
me that "color" is not a function. What should I do ? Thanks again.

But what if the HTML sets it user-defined color, without caring about
OpenLayers, and instead is OL itself going to read the color in the HTML
div? 
I mean, from the function inside the context of the style, you read the
color. ?

With JQuery for example you can do it simply. 

I just don't know if the color of the features would change as the div color
changes, however.
Have a trial... :)

Through something as Mapserver or Geoserver.

You can get them as raster via WMS (if you have a web map service...), or as
vector features via OpenLayers.Layer.Vector or OpenLayers.Layer.WFS.

I used to get the PNG raster of my shapefile like this (I have GeoServer as
WMS):

		var myShapeFile = new OpenLayers.Layer.WMS('Name',
				WMSURL, 
				{layers: WORKSPACE + ':' + ,
				transparent: 'true', // Visualize all rasters at the same time
				opaque: 1,
				format: 'image/png8'},
				{opacity: 0.4, singleTile: true, transitionEffect: 'resize'}
			);

	        OLmap.addLayer(myShapeFile);

Take a look at the examples code, it may be useful (e.g.
http://openlayers.org/dev/examples/wfs-protocol-transactions.html)

Hi Piero,
      Thanks for giving response. Actually i'm using TerraGate SFS Manager.
I have a couple shape files. I need to get those shape files(wfs) on to the
map using openlayers. so, how can i do this using TerraGate SFS Manager??

Hi,
Does anyone know if it's possible to "enforce" labelling all polygon objects
using SLD, even if the labels overlap? (sth like "Place overlapping labels"
option in ArcGIS). Does OpenLayers support such things?
Best regards,

I can see
(http://www.skylinesoft.com/SkylineGlobe/Corporate/Products/TerraGateSFSServices.aspx)
that TerraGate SFS Manager provides WFS/WMS services, so it's just a matter
of getting the WFS URL (or WMS URL), and the name of the shapefile as it is
stored in TerraGate.

If you want to retrieve the shapefile as vector feature (and not raster),
you can try:

		var myshapeFile = new OpenLayers.Layer.Vector("Name", {
			styleMap: myStyleMap, // optional
			strategies: [wfsOpenLayersStrategy], // e.g. new
OpenLayers.Strategy.BBOX()
			filter: myFilter, // see
http://dev.openlayers.org/apidocs/files/OpenLayers/Filter-js.html
			protocol: new OpenLayers.Protocol.WFS({
				url: WFSURL,
				featureType: SHAPEFILE_NAME,
				featureNS: NAMESPACE_URI,
				srsName: "EPSG:900913", // your map projection (here is for Google Maps)
				version: "1.1.0" // : supports reprojection from ShapeFile SRS to OLmap
SRS
				})
		});

Usually you have less problems by getting the PNG raster of the shapefile,
but you hav less skills.
Have some trial, and be patient. :)

Thanks Piero,

The first link is definitely a good example to rely on for most typical click 
events (with the left/default mouse button).  But it still lacks the ability 
to catch a right click.  I tried to mimic this in the html file I attached to 
my first message, but the 'rightclick' method that is noted in the 
documentation doesn't actually seem to do anything...while similar 
mouseup/mousedown events are also treated as single-clicks.

It's not a big deal I guess...it would just be nice to handle all these events 
through the same set of objects if possible, rather than working around it.  
But in any case, here's what I've got so far, using a bit of jQuery:

$(map.div).bind('contextmenu',function(e){
	e.preventDefault();
});

$(map.div).mouseup(function(e){
	if (OpenLayers.Event.isRightClick(e)){
		console.log("Right button click up");
		e.xy = map.events.getMousePosition(e);
		e.geoxy = map.getLonLatFromPixel(e.xy);
		// Do more stuff...
	}
});

That seems to be enough to get me going for now - unless anyone can make any 
further recommendations.

Thanks for the help.

Mike

Subject: [OpenLayers-Users] Displaying images even at the edge of the screen
Message-ID: <1279885436321-5329187.post@n2.nabble.com>


Hello!

I'm wondering if it's possible to make images display even if it is not in
the middle of the screen.

I display the image through a stylemap in a vector layer with a vector
feature deciding the coordinates that it's drawn at (In addition to that, is
there maybe a way that performs better than that?). I'm trying to draw floor
plans on a building, and for the floor plan to be displayed I have to move
the map to the middle of where it's drawn before its actually visible, then
after that I can pan around the whole image without it being a problem.

So if there's a way to make images show even if its just a tiny bit of it
that should be visible on the current viewport of the map then I'd be very
happy if someone could tell me.

OpenLayers has no label collision detection; all labels will always be displayed,
regardless of any collisions. I don't know if this is an option in SLD,
but if it is, we don't do anything with it, as far as I know.

Hi people, how are you doing?

I'm having troubles to find the way to zoom to a polygon WMS layer that is
dinamically filtered.. 

Let's put this on an example:
You have the USA states map and you have an ID for each state; you define
your WMS layer to something like this:

    var stateID = funcToGetFromURLParam("stateID");

    states = new OpenLayers.Layer.WMS(
        "States", "http://server:8080/geoserver/wms",
        {
            transparent: 'true',
            layers: 'Workspace:states',
            srs: 'EPSG:4326',
            format: 'image/png',
            filter:
"<Filter><PropertyIsEqualTo><PropertyName>ID</PropertyName><Literal>"+stateID+"</Literal></PropertyIsEqualTo></Filter>"
        });
    map.addLayer(states);

How would you zoom to this layer (to it's maximum extension, to it's
bounderies.. got what I tried to say?) after is filtered and loaded? I tried
in so many ways but I could not. :S

Thanks for your time folks!

Best regards,

getFeatureById() and OpenLayers.Layer.Vector.selectedFeatures both return

I do something like:

var obj = new OpenLayers.Geometry.LineString(points);
var polygonFeature = new OpenLayers.Feature.Vector( obj );

It shows up find but goes away on zoom and does not come back, even on the
same zoom level. Do You have to redraw them?

You didn't share enough code to know, but my guess is that you call 
drawFeature, rather than addFeatures(). addFeatures adds it to the 
layer + tracks it going forward; drawFeature just draws it once.

Hi,

OpenLayers have no possibilties to get the extent from the WMS. 

You can try to get the extent 

by WMS GetFeatureInfo (if you have a point, that indicates the state) or 
by WFS using the stateId for filter the WFS GetFeature.

and then
map.zoomToExtent(Bounds);

Hi,
 
you can use the OpenLayers.Control.SelectFeature. There is a function select
with a feature to select as argument.
 
ctrlSelectFeatures = new OpenLayers.Control.SelectFeature(...);
 
function radioSelectFeature(idx)
{
    var vlyr = map.layers[1];
 
    try{
        ctrlSelectFeatures.unselect(vlyr.selectedFeatures[0]);
    }catch(err){document.getElementById("featDesc").innerHTML='error'};
 
    ctrlSelectFeatures.select(vlyr.features[idx]);
}

You can use:

OpenLayers.Layer.Vector.getFeatureById()

or the undocumented/private/I can't find it in the api docs

OpenLayers.Layer.Vector.selectedFeatures array.

Sorry, I forgot to mention the undocumented select(), as Arnd already

Hi all,

Is it possible to show postgis data in openlayers?

If yes can some body points me to some links or upload a working example to 
illustrate.

A usecase can be:
Consider a road table (road_id, geom, road_name) in the postgre/postgis 
database. In SQL the select statement can be [SELECT road_id, 
ST_AsText(road_geom) AS geom, road_name FROM roads;] to select all the roads. 
Now how to give it to openlayers to show them on the map.


Thanks,

George,

You need some application on the server side like:

- mapserver that can connect to the database and render a map image. 
There are other application that can do this, some in java if you prefer.

- or you can do the query on the servlet and format the results into GML 
or GeoJSON, but this in only viable if you have under 1000 features that 
you are rendering at any give time. And 1000 might be pushhing the limit 
depending on the browser performance and memory.

Thanks, Steve for your reply.

Ok if your are talking about a mapping server, than lets put it this way. I?have 
installed and configured?GeoServer and using the postgis option available in it, 
the layers are published. Now using WMS or WFS services,?layers are requested 
and shown on the map.

Some question arises:

(1) What is the benefit of using PostGIS then? Where the use of postgis can 
benefit me? These layers can be easily published in the same way through shape 
files and shown on the map. OR may be I misunderstood it.

(3) About searching: suppose there is a textbox on the page through which the 
user can search and zoom to?a specified feature. (Relating to my example, 
suppose user enters the name of a road). How this can be achieved. Would the 
postgis or geoserver sort this problem out?

(4) If there are multiple layers (For e.g roads, cities, train stations, 
schools, etc). How can the functionality of searching through a single textbox 
be implemented.

(5) How one can perform some spatial analysis and show it on the web? (e.g. A 
user wants to view major roads with in 5km radius reference to his home)

I have seen question/topic related to these issues on the forum, but 
unfortunately no satisfactory answer was given.

What are your suggestions?

Thanks,
--
Matt

- mapserver that can connect to the database and render a map image. There are 
other application that can do this, some in java if you prefer.

- or you can do the query on the servlet and format the results into GML or 
GeoJSON, but this in only viable if you have under 1000 features that you are 
rendering at any give time. And 1000 might be pushhing the limit depending on 
the browser performance and memory.

I agree with Phil, their should be built-in support for spherical mercator
aliases after all. The (now) documented work-around does not work if you
need to overlay multiple layers from providers that each support a different
alias.

The idea that Phil published seems to be the best solution I've seen so far.
As long as this type of solution is not part of OpenLayers, this kind of
override can do the trick. The code that Phil provided depends on Ext and
the word 'arcgis' in the Url. I modified it slightly to remove the
dependencies and support a new layer option 'sphericalmercatoralias'. 

// override OpenLayers.WMS.getFullRequestString class member function
OpenLayers.Layer.WMS.prototype.getFullRequestString = function(newParams,
altUrl) { 
	var projectionCode = this.map.getProjection(); 
	if (this.options.sphericalmercatoralias)
	{
		if(projectionCode == 'EPSG:900913' || projectionCode == 'EPSG:102113' ||
projectionCode == 'EPSG:3857') { 
			this.params.SRS = this.options.sphericalmercatoralias; 
		} else { 
			this.params.SRS = (projectionCode == "none") ? null : projectionCode; 
		} 
	}
	return OpenLayers.Layer.Grid.prototype.getFullRequestString.apply( this,
arguments); 
}

After this override, you can set a new layeroption 'sphericalmercatoralias'
to tell OpenLayers to use that instead of the default as follows:

layer = new OpenLayers.Layer.WMS(title, url, {layers},
{sphericalmercatoralias: "EPSG:102113"});

Quite obvious, but with a database, you have the possibility to use SQL
(spatial SQL for PostGis).
For data extraction, WMS or WFS are not very performant. Several web mapping
applications are using REST services. These REST services are quite easy to
implement with a database in back end and can be fine tuned if you use a
database (indexing, spatial indexing)

In this case, I would implement a search service. Postgres Full Text Search
is very performant. SQL queries can also be used, of course.

Which level of performance do you want to reach ? It's clear that searching
in multiple table and in multiple attributes can be quite slow. As solution,
you can store everything in one table (only for search purpose. Materialized
view can be of interest). Or you can multithread the search, but, in this
case, you have probably to take in account the server load.

Again, with a web service using spatial capabilities of the database. WPS
can be of interest in that regard.

Again, your questions are very general and can be solved in various ways.
The answers depend also of the expected number of users of your web mapping
application, the use cases you want to cover, the expected performance and
ergonomy, the technology context of your company etc, etc.. This explains
also why the OSGEO groups several project (http://www.osgeo.org/) that
partially overlaps.

Hmm, 

I didn't test my code properly, (layers without option sphericalmercator
stopped working). The following code should do better (Version >= 1.3 not
yet tested):

// override OpenLayers.WMS.getFullRequestString class member function
OpenLayers.Layer.WMS.prototype.getFullRequestString = function(newParams,
altUrl) { 
	var projectionCode = this.map.getProjection();
	var value = (projectionCode == "none") ? null : projectionCode
	if (this.options.sphericalmercatoralias)
	{
		if(value == 'EPSG:900913' || value == 'EPSG:102113' || value ==
'EPSG:3857') { 
			value = this.options.sphericalmercatoralias; 
		} 
	} 
	if (parseFloat(this.params.VERSION) >= 1.3) {
		this.params.CRS = value;
	} else {
		this.params.SRS = value;
	}

	return OpenLayers.Layer.Grid.prototype.getFullRequestString.apply(this,
arguments);
}


After this override, you can set a new layeroption 'sphericalmercatoralias'
to tell OpenLayers to use that instead of the default as follows: 

layer = new OpenLayers.Layer.WMS(title, url, {layers: layernames},
{sphericalmercatoralias: "EPSG:102113"});

Hi,

I wouldn't restrict it to sphericalmercatoralias. I use a similiar approach
to add WMS Server, which use a different EPSG code than my map, but describe
the same projection.

Why not use options.projection to request the WMS in this projection?

OpenLayers.Layer.WMS.prototype.getFullRequestString =
function(newParams,altUrl)
{
    try{
        var projectionCode = typeof this.options.projection == 'undefined' ?
this.map.getProjection() : this.options.projection;
    }catch(err){
        var projectionCode=this.map.getProjection();
    }

    var value = (projectionCode == "none") ? null : projectionCode
    if (parseFloat(this.params.VERSION) >= 1.3) {
        this.params.CRS = value;
    } else {
        this.params.SRS = value;
    }

    return OpenLayers.Layer.Grid.prototype.getFullRequestString.apply(this,
arguments);
},

Hello Arnd,

An option named "sphericalmercatoralias" is indeed very specific to
sphericalmercator.
Maybe, an option named "projection" is not specific enough. Users could
think that such an option would somehow magically allow reprojecting the
overlay projection to the map projection. Things would get mixed up, when
sending bounding box coordinates using the wrong projection.
So maybe an option named "projectionalias" would be a better name than
"sphericalmercatoralias" or "projection"?
"projectionalias" stresses the fact that the projection itself should not be
different, just the code that is being used for the projection.

Anne

Subject: [OpenLayers-Users] Adding radiobuttons to LayerSwitcher
Message-ID: <AANLkTikAHUsMwZwAuRqy+CUD+Cz_7pdiv7fDafM6on-L@mail.gmail.com>

Hi,

when adding a layer to the map, it is displayed with a checkbox in the
layerswitcher. Now I want to add radiobuttons right to the layernames in
layerswitcher. And then, when selecting one of them, a event should occur.
Yes I know there is Geoext for stuff like this, but after I looked at the
LayerTree example and didn't understand a thing... I want to stay with
OpenLayers.
which possibilities are there to realize this with OL?

I hope you have any ideas..

Hi,

what would people think about the following:

layer.projection -> the SRS to use in OpenLayers internally
layer.params.SRS (or layer.params.CRS etc.) -> the SRS to send to the server

Currently, we overwrite params.SRS/CRS/... with layer.projection. Nobody says we have to.

Opinions?

Regards,
Andreas.

hi,
that's exactly what I need! But I want use it with the layer-group function
.
So now I have layer-grouping via :
http://www.cnblogs.com/iswszheng/archive/2009/12/15/1625069.html and
additional radiobuttons via
http://gis.ibbeck.de/ginfo/apps/OLExamples/OL26/examples/javascript/LayerSwitcherRadioReg.js(
http://gis.ibbeck.de/ginfo/apps/OLExamples/OL26/examples/labels_radiobtn.html).
Is there someone, who has time to merge these both functions (because I'm
not able of developing OL source code), so that every layer in the
layerswitcher with group functionality has a radiobutton ?

...would be awesome :)

Message-ID: <OF6FFB45EB.2A7951D2-ONC225776C.003BF1C3-C225776C.003D613F@LocalDomain>

Hi all,

I have problem in VirtualEarth ,

I have some markers and circle layers on my VirtualEarth ,in zoom level 
0,1,2 when I pan the map my markers and circles are sliding independent 
from map when I increase the zoom level markers and circles relocate 
successfully.

I think problem is releated to in VirtualEarth  there is no enough panning 
area in zoom level 0,1,2 .So when you pan the map only our custom layers 
are moving.

There is no such this problem in our google or custom tile layer.

Any ideas or settings for this?


Best Regards
Tamer

Hi Anne,

I agree, something like 'projectionAlias' is better to understand than
projection.

Hello Arnd,

An option named "sphericalmercatoralias" is indeed very specific to
sphericalmercator.
Maybe, an option named "projection" is not specific enough. Users could
think that such an option would somehow magically allow reprojecting the
overlay projection to the map projection. Things would get mixed up, when
sending bounding box coordinates using the wrong projection.
So maybe an option named "projectionalias" would be a better name than
"sphericalmercatoralias" or "projection"?
"projectionalias" stresses the fact that the projection itself should not be
different, just the code that is being used for the projection.

Anne

Hi,
 
I wouldn't take code from that example. It's a terrible hack by me to get
the functionality of set the active layer. I have only replaced the code of
the OpenLayers.LayerSwitcher without the right understanding what's going
on.

when adding a layer to the map, it is displayed with a checkbox in the

Yes I know there is Geoext for stuff like this, but after I looked at the

OpenLayers.

which possibilities are there to realize this with OL?



I hope you have any ideas..

var linearRing = new OpenLayers.Geometry.LinearRing(points);

OpenLayers.Geometry.Polygon([linearRing]);
	 if (type == "poly" || type == "Poly") var obj = new

I have a few features on my map and they tend to jump around after I move the
map and let go of the mouse button. They stay glued well when dragging, its
button up that makes it jump. The X is not bad, but the Y seems to jump
about 100 px or so. what could I have wrong?

Using Google Maps/Virtual Earth without using spherical mercator, is my guess.

ah then that explains it I had to remove that as it made the map still. Any
idea why using sphericalMercator would cause the map to stay stationary and
not allow moment? Zoom seems to load the right detail zoom layer but its
always set to 0,0 and I can not move outside of that.


here is what I have.


GoogleAerial = new OpenLayers.Layer.Google(	"Google Streets" ,	{type: 
G_NORMAL_MAP, 'sphericalMercator': true,  numZoomLevels: 22} );

You didn't set the maxExtent on your Map object:

indeed that helped.

now I set a point something like

var proj = new OpenLayers.Projection("EPSG:4326");
var point = new OpenLayers.LonLat(-71, 42);
point.transform(proj, map.getProjectionObject());


how can I use getCenter so that it runs lot and lan. It seems now to return
the transformed?

Subject: [OpenLayers-Users] map with position:absolute not displayed in ie
	<= 7
Message-ID: <20100726213532.GA23375@localhost>

Hi,
I want to have displayed on the whole page except a 2em height footer.

So, I've tried to set my css to :

#map {
    position: absolute;
    top: 0; left: 0; right: 0;
    bottom: 2em;
}

It works fine in every browser I tested except in ie6 and ie7.
For those browsers, I absolutely need to set a width and height css 
properties. For example: width: 100% and height: 100%, otherwise the map does 
not show at all: it stays a white area. But as height: 100% - 2em does not 
exist, I can't have the behaviour I want.

What's strange is that a "normal" div (not an ol map) is correctly displayed 
with { position: absolute; top: 0; left: 0; right: 0; bottom: 2em; } in ie.

What's strange also is that map images are downloaded from the tile server.

Here is an example of a map showing correctly except in ie6 and ie7:

http://renevier.net/bugs/ol_absolute.html

Do you have any clue of why this problem happens, and/or any workaround ?

regards
arno

Unfortunately, I don't have any advice for you (I'm not currently set up to
debug IE), but I did want to thank you for such a concise and well-written
explanation, with simplified example, of the problem you're having. This is
an excellent example of exactly how to ask a good question.

I do feel kind of bad I can't provide a good answer in response :)

Arno,

I have also encountered this issue. The solution I came up with was to
switch the div to position:fixed and to have a helper JavaScript function to
resize the div every time the window changed size. If you plan on having
items on the page other than just the map you may need to adjust your CSS
positioning for those items as well if you end up going this route.

function windowResize() {
        /* Do Resizing events through JavaScript */
        /* Detect Height and Width of page */
        /* Do whatever adjustments you wish to add to the height and width,
then set to the div */
        /* div.style.top = "0px"; // How far from the top you wish the div
to start at
        div.style.left = "200px"; // How far from the left you wish the div
to start at
        div.style.height = newHeight+"px";
        div.style.width = newHeight+"px";*/
}
window.onresize = windowResize;

Thank you so much C?dric for an elaborative reply.

I want to perform online spatial analysis and show it on the map.

(1) Suppose I enter a buffer zone in a textbox now I want to see how many parks 
are inside that buffer zone near my house. The parks inside the buffer zone 
should be highlighted.

(2) As there can be different types of parks, like national park, muncipal park, 
etc. How to?highlight that area having only?national parks.

The data of parks and houses are stored in the postgresql/postgis database as 
point features.

How to implement it using OpenLayers, GeoServer, PostGIS and if required Server 
side technology like PHP or Java can also be used.


Thanks,
--
Matt

Hi,
There is for sure not only one answer to your general questions, so let me try 
to provide one possible answer for them.

Quite obvious, but with a database, you have the possibility to use SQL (spatial 
SQL for PostGis). 

For data extraction, WMS or WFS are not very performant. Several web mapping 
applications are using REST services. These REST services are quite easy to 
implement with a database in back end and can be fine tuned if you use a 
database (indexing, spatial indexing) 


(3) About searching: suppose there is a textbox on the page through which the 
user can search and zoom to?a specified feature. (Relating to my example, 
suppose user enters the name of a road). How this can be achieved. Would the 
postgis or geoserver sort this problem out?
>

In this case, I would implement a search service. Postgres Full Text Search is 
very performant. SQL queries can also be used, of course.? 


(4) If there are multiple layers (For e.g roads, cities, train stations, 
schools, etc). How can the functionality of searching through a single textbox 
be implemented.
>
Which level of performance do you want to reach ? It's clear that searching in 
multiple table and in multiple attributes can be quite slow. As solution, you 
can store everything in one table (only for search purpose. Materialized view 
can be of interest). Or you can multithread the search, but, in this case, you 
have probably to take in account the server load.? 


(5) How one can perform some spatial analysis and show it on the web? (e.g. A 
user wants to view major roads with in 5km radius reference to his home)
>
Again, with a web service using spatial capabilities of the database. WPS can be 
of interest in that regard. 


I have seen question/topic related to these issues on the forum, but 
unfortunately no satisfactory answer was given.
>
Again, your questions are very general and can be solved in various ways. The 
answers depend also of the expected number of users of your web mapping 
application, the use cases you want to cover, the expected performance and 
ergonomy, the technology context of your company etc, etc.. This explains also 
why the OSGEO groups several project (http://www.osgeo.org/) that partially 
overlaps.

?? 

What are your suggestions?

Subject: [OpenLayers-Users] Resolutions with Geowebcache and
 WMSGetFeatureInfo [Sec=Unclassified]
Message-ID: <A83C532A23D1BB4B874F48AD3013F43302E87AE4B554@EX2K7-CCR.AAD.GOV.AU>

Hi,

I've been debugging a problem that I've been having with using the WMSGetFeatureInfo control and GeoWebCache.

Basically I am setting OpenLayers.DOTS_PER_INCH to 90.71428571428572 which is what GeoWebCache expects by default, however when the WMSGetFeatureInfo request goes through to GeoWebCache it is like it's using the default 72 for DOTS_PER_INCH, because all of the resolutions are about 21% out.

GeoWebCache responds with messages such as :"400: Requested horizontal resolution: 0.54931640625 , best match: 0.703125 exceeds 10% threshold. Perhaps the client is configured with an incorrect set of scales (resolutions), or the DPI setting is off compared to the one in GWC ?"

I've actually just dropped the WMSGetFeatureInfo control into a GeoWebCache OpenLayers demo, so the resolutions are definitely set up to match. The full source (pretty short and simple) is at http://pastebin.com/JENnAPC9.

I've brought it up on the GeoWebCache mailing list but now thinking that it's more likely something to do with OpenLayers. Here's a link to my messages: http://tinyurl.com/38jvcva

It seems like the resolution would be calculated incorrectly by about that amount if the DOTS_PER_INCH were still at 72, so I'm wondering if there's another setting that I need to change or if there's a bug somewhere.

Your comments are appreciated.

I fumbled with the controls for a while and then managed to do it the way you
proposed, adding the vector.redraw() made it work. But now, when it draws
the polygons with the colors I select, now I can't draw polygons -the ones
without specifying the number of sides-, lines and points. I can only draw
the regular polygons-with specified sides- and also, if I have drawn two
polygons with different colors, the selected polygons turn into the color of
the last one drawn. How can I tackle this ? I'm posting the code below: 


var myStyleMap = new OpenLayers.StyleMap(
                        new OpenLayers.Style({
								fillColor: '${color}',
                                strokeColor: '${color}'},
                                //call attribute of style in order to modify
                         {
                                context: {
                                        color: function(value) {
										if(value == "purple")
													{
														selectedColor = "purple";
														
													}
													else if(value == "blue")
													{
														selectedColor = "blue";
														
													}
													else if(value == "yellow")
													{
														selectedColor = "yellow";
														
													}
													else if(value == "red")
													{
														selectedColor = "red";
														
													}
													else if(value == "orange")
													{
														selectedColor = "orange";
														
													}
													else if(value == "green")
													{
														selectedColor ="green";
													}
														
                                                // Here define your JS
function that picks the color from the HMTL element
                                                
													return selectedColor;
													vector.redraw();
													kamap.redraw();
                                                },
                                },

Oh I forgot, kamap is the base layer and color selection is called in HTML
part.

<select id="colors" onchange="color(this.value)"><!-- call problem FIXME -->

_________________________________________


I have in a website a list of species (Reptils) with a short description and
I want to show each species on a map. Then, when I click on one
"Acanthodactylus erythrurus", I want to expand automatically, for example,
from "Reptils" -> "Acanthodactylus erythrurus" -> "Scenario A2" -> "2020"
and check "2020", to know which layer is active.


Is this possible?


Thank you very much,
Ferm?

You can't return AND then execute some more code.

Hi,

the problem I see with your approach is that OpenLayers.Control.GetFeatureInfo creates a GetFeatureInfo request for the map extent, not for a tile. I would recommend sending GetFeatureInfo requests to the underlying WMS, as explained in http://getsatisfaction.com/opengeo/topics/error_in_wmsgetfeatureinfo#reply_2612983

Regards,
Andreas.

Hi Chris,

*> Then I recommend doing more research into how browsers work. :)*

I am quite sure my question is stupid ! But look to this simple code:

<?xml version="1.0"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "
http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<body>
<h1>Just a Rectangle</h1>
<svg
   xmlns:svg="http://www.w3.org/2000/svg" xmlns="http://www.w3.org/2000/svg"
version="1.0" width="150" height="150" id="svg1341">
  <rect width="90" height="90" x="30" y="30"
style="fill:#0000ff;fill-opacity:0.75;stroke:#000000;stroke-width:1px"
id="rect1353" />
</svg>
  </body>
</html>

 if this code is in a file with filename
- test.xhtml it's working
- test.html nothing displayed.

My current understanding is that if you want to add SVG to a HTML page, you
need to use createElementNS and NS = "http://www.w3.org/2000/svg"
in this case it will works even if the page  is declared a HTML and not
XHTML.
You cannot insert SVG in a HTML page except in the SVG is added via
javascript

Is that correct ?
*

>I'm not sure I understand what you're doing. Can you share
> the OpenLayers JavaScript you are attempting to use?*

I finally manage to realize what I wanted. Maybe there is a better way.

My Use case:
In a KML file, I have two polygons. One is a mask, the second is the polygon
I want to clip

How I did:
To realize that I want to use the "clipPath" of SVG
First I need to add <defs><clipPath>mypolygonmask</clipPath><defs> to the
SVG renderer
Then I need to add clip-path attribut to my second polygon.

          GMLlayer.events.register("loadend", GMLlayer, function() {
                        id = this.id;
                        id = id.replace(/\./g, '\\.');

                        //Add <defs> to SVG Renderer when the layer is
loaded
                        var defs = document.createElementNS("
http://www.w3.org/2000/svg", "defs");
                        var clipPath = document.createElementNS("
http://www.w3.org/2000/svg", "clipPath");
                        clipPath.setAttribute("id","decoupe");
                        var path = document.createElementNS("
http://www.w3.org/2000/svg", "path");
                        path.setAttribute("id","decoupepath");

                        features = this.features;
                        //Mask polygon is identified in the KML by name =
Mask
                        for(i=0;i<features.length;i++) {
                            if (features[i].attributes.name == "Mask") {
                                maskid = features[i].geometry.id;
                                maskid = maskid.replace(/\./g, '\\.');
                                pathO = $("#"+maskid).get(0);

                                #Path0 can be NULL, if the polygon mask is
not in the current viewbox
                                if (pathO)

path.setAttribute("d",pathO.getAttribute('d'));
                                continue;
                            }
                        }

                        clipPath.appendChild(path);
                        defs.appendChild(clipPath);

                        root = $("#"+id+"_svgRoot").get(0);
                        root.appendChild(defs);

                        # Add clippath attributes
                        $("#"+id+"_root").attr('clip-path',"url(#decoupe)");
                    });


          //Any time the zoom is changed, the polygon is the SVG are
regenerated by openlayers, so the mask should be updated too
          map.events.register("zoomend", GMLlayer, function(e) {
                        id = this.id;
                        id = id.replace(/\./g, '\\.');

                        features = this.features;
                        for(i=0;i<features.length;i++) {
                            if (features[i].attributes.name == "Mask") {
                                maskid = features[i].geometry.id;
                                maskid = maskid.replace(/\./g, '\\.');
                                pathO = $("#"+maskid).get(0);
                                //alert(maskid);
                                //alert($("#"+id+"_vroot
path:first").attr('id'));
                                pathClip = $("#decoupepath").get(0);
                                if ((pathClip)&&(pathO))

pathClip.setAttribute("d",pathO.getAttribute('d'));
                                continue;
                            }
                        }
                    });

Hi all,
I'm drawing polygon over a Google base layer.

Even though I set wrapDateLine to true in the Google base layer, the Vector
layer AND the temporary layer created by the RegularPolygon handler, still
when I draw a polygon I cannot cross the IDL. 

Any idea guys?
Thank you,
Piero

Hi,

That way you have to set the SRS in the params and the projection in the
options. 

I would think, it's better, the params get the projection from the map and
if you want to overwrite the SRS use projection or projectionAlias in the
options.

That way you have only one change not two. 

Also I think, it's better, that one could only overwrite WMS params, which
OpenLayers couldn't set by itself like version, layers etc.

Arnd

If you have set a projection in the map options, you don't have to set it again on the layer.

Are you sure that the src URL is a valid license for your server? 
http://code.google.com/apis/maps/signup.html

After that you can use Firebug and break somewhere in your code to ensure
the globals like G_SATELLITE_MAP are shown in your Watch tab (this.)

hi!

what about expanded: true ?

Ok. Then it's regardless, which way to use. I would prefer 'projectionAlias'
in the options.

If you have set a projection in the map options, you don't have to set it

Hello OpenLayers users,

I sent this email previously, but do not believe it went through -
apologies in advance for any duplication. I realize the users
list-serv is for more technical aspects but considering the low volume
on the Announcements list-serv, I wanted to make sure this message
reached the full developer community.

I am writing to you all as an Editor of Global Pulse, the
international health journal of the American Medical Students
Association. We are an open-access, 100% volunteer, student run
journal.

We are interested in using OpenLayers to develop a map or the archives
of our journal, dating back to its inception in 2005.  We seek to
georeference each story that has appeared and create a webmap page on
the site for readers to explore our stories. We also want to bring in
feeds from other geotagged content, such as  Wikipedia and Photos from
flickr, etc. We would like to be able to toggle by year and content
type (research, reflection, photoessays).  We estimate the total time
for the project to be around 40 hours.

Though we would need to rely on volunteer power to complete this
project, we hope to utilize it as a pilot to apply for grants in order
to create a larger, wiki style map (we estimate this project to
require 5k-10k+ in funds to develop) so your volunteer with this
project could lead to future work.  If you or anyone you know would be
interested in helping with this project in any way, please feel free
to contact me directly. Again, this would be a volunteer project with
the possibility of future paid work.

Sincerely,
John Pearson

Subject: [OpenLayers-Users] externalGraphic anchoring points?
Message-ID: <4C4EB794020000C70003F405@PLUTO.UND.NODAK.EDU>

All,

Hi, new user.  I'm using a vector layer for placing markers on the map, and I'm using the externalGraphic property to specify a marker of my own.  How is that image anchored with respect to the lat/lon coordinates that it represents?

That is, if exactly one pixel in the external graphic corresponds to the point on the map, is it:

a) The top left corner pixel
b) The top right corner pixel
c) The bottom left corner pixel
d) The bottom right corner pixel
e) The exact center pixel
f) A pixel halfway along one edge
Or g) something else entirely?

I need to know so that I can figure out the correct offsets to use with my graphic.

I tried to figure this out by using an external graphic for the marker which was a 1x1 pixel animated GIF blinking red/white/red/white and then defining another marker for the same coordinates with a translucent version of the regular image.  But the 1x1 graphic refused to show up, even when I disabled the other marker so that it was on its own.  Weird.

Thanks!

I believe the origin of an image is the upper-left corner, so you need 
to specify your offsets based on that point.

I don't think so. I believe externalGraphics center, by default, on the 
center of the image. (I don't know what happens for images where this is
a half pixel; I assume we round somehow, but I don't know how.)

It's the center of the image.

Easy to see if you connect two images with a line :-)

Make sure the line feature is added to the layer before the two images(point
features), then the line will usually show up on top.

See example:

Message-ID: <005f01cb2db6$2e2fbf50$8a8f3df0$@de>

I want to draw a WFS Source from GeoServer. 

It's working, but very slowly. Firefox stop the script because it?s slow. 

There are only 16 polygons with some rules. Is that speed normal? Can i
speed up it?

Have somebody a idea?

 

 

var style_11 = new OpenLayers.Style();

var rulenr17 = new OpenLayers.Rule({

  title: "5000-<6000",

  filter: new OpenLayers.Filter.Comparison({

        type: OpenLayers.Filter.Comparison.BETWEEN,

        property: "d_wert",

        lowerBoundary: 5000,

        upperBoundary: 6000}),

  symbolizer: {fillColor: "#FEE5D9",

       fillOpacity: 0.9, strokeColor: "black"}

});

var rulenr18 = new OpenLayers.Rule({

  title: "6000-<7000",

  filter: new OpenLayers.Filter.Comparison({

        type: OpenLayers.Filter.Comparison.BETWEEN,

        upperBoundary: 7000}),

  symbolizer: {fillColor: "#FCAE91",

        fillOpacity: 0.9, strokeColor: "black"}

});







style_11.addRules([rulenr17,rulenr18,rulenr19,rulenr20,rulenr21]);

var haeufigkeitsverteilung = new OpenLayers.Layer.WFS(
"H?ufigkeitsverteilung 2009",

        "http://zimrob.com:8080/geoserver/wfs",

        {typename: 'crimewebgis:pks_haeufigkeitsverteilung_2009'},

        {extractAttributes: true,isBaseLayer:true,visibility:false}

);

map.addLayer(haeufigkeitsverteilung);

haeufigkeitsverteilung.styleMap = new OpenLayers.StyleMap(style_11);

Hello Piero,

You may have to adjust the coordinates to 'saddle' the IDL.  For example, a
rectangle with the coordinates:

170, 10  -------+------  -170, 10
   |            |            |
   |            |            |
   |           IDL           |
   |            |            |
   |            |            |
   |            |            |
170, -10  ------+------  -170, -10

May extend the "wrong way" around the globe.  If you manually adjust the
coordinates so they are all on the same side of the IDL, it will probably
work:

-190, 10  --------------  -170, 10
    |                         |
    |                         |
    |                         |
    |                         |
    |                         |
    |                         |
-190, -10  -------------  -170, -10

or:

170, 10  --------------  190, 10
   |                        |
   |                        |
   |                        |
   |                        |
   |                        |
   |                        |
170, -10  -------------  190, -10

Notice that in the last two examples, the X coordinates are either all
positive, or all negative. I have found this to work quite well; you can
even extend this to keep adding features to 'globes' that are beyond -180.
There is one thing to be wary of, though: when you do cross the date line,
the entire geometry will jump to the left or right by 1 globe
circumference.  I don't have a workaround for that, but you can trick OL by
adding features to the neighboring 'globes'.

I have always thought the anchorpoint is left-top. But your nice example
suggest it's the center of the externalGraphic.

Looking at the code, it seems to be a bit complexer. 

SVG.js, similiar for VML.js
var xOffset = (style.graphicXOffset != undefined) ? style.graphicXOffset :
-(0.5 * width);
var yOffset = (style.graphicYOffset != undefined) ? style.graphicYOffset :
-(0.5 * height);

If you declare the properties graphicXOffset and graphicYOffset in your
style, then these values are taken for drawing. If you omit these
properties, then an offset of half the width or height are taken.

Because I use always the properties graphicXOffset=0 and graphicYOffset=0 in
conjunction with externalGraphic, I have the anchorpoint always at left-top.
 
If you want to use an offset to move the image, then you have to calculate
from left-top and not from the center as your example seems to show.

Arnd

Hey-

The OpenLayers.Layer.WFS layer cannot be used with a style map.

Use the OpenLayers.Layer.Vector layer instead (as do all of our WFS 
examples): http://openlayers.org/dev/examples/?q=wfs

Though you may have a small number of features, they look to have a 
large number of coordinates.

 From where I sit, the document below took 10 seconds to load (4 seconds 
waiting, 4 seconds receiving, and about 2 seconds parsing).  That's the 
time required before the OpenLayers GML parser even has a chance to start.

http://zimrob.com:8080/geoserver/wfs?request=GetFeature&typename=crimewebgis:pks_haeufigkeitsverteilung_2009

You may have to do some work on the server side (simplifying features) 
before you can expect better performance on the client.

Subject: [OpenLayers-Users] extract attributes from a geoserver wms
Message-ID: <AANLkTinck9KZ24XAVF_x3PkaQR1jqp=Z6OYw=eC8qjV2@mail.gmail.com>

Hi all,
my problem is:
I have a map with two wms layers served by GeoServer, and would like
to display in a pop-up some attributes of the second layer.
I would also like to customize the pop-ups.
I tried several ways but the one I work is:
#info = new OpenLayers.Control.
#WMSGetFeatureInfo ((
#            url: 'http://10.0.0.161:8080/geoserver/wms',
#           title: 'Identify features by clicking',
#            queryVisible: true,
#            eventListeners: (
#                getfeatureinfo: function (event) (
#                    map.addPopup (new OpenLayers.Popup.FramedCloud (
#                        "Chicken"
#                        map.getLonLatFromPixel (event.xy)
#                        null
#                        event.text,
#                        null
#                        true
#                    ));
#                )
#            )
#        ));
#        map.addControl (info);
#        info.activate ();

With this code, however, I see the pop-up with "all" attributes in a table.
There is an alternative way, which doesn't uses GML, KML and other
formats, but uses only wms or wfs?

Another problem:
I tried with wfs but even I can not see nothing on the map!
I've tried with this code:

#var wfslayer = new OpenLayers.Layer.Vector("WFS", {
#   strategies: [new OpenLayers.Strategy.BBOX()],
#   protocol: new OpenLayers.Protocol.WFS({
#             url:  "http://10.0.0.161:8080/geoserver/wfs",
#             featureType: "aeroporti",
#             featureNS: "http://geoserver.org",
#             srsName: "EPSG:4326",
#             version: "1.0.0"
#             })
#});


thanks to all

Subject: [OpenLayers-Users] pb with Strategy.Refresh
Message-ID: <4C4FE161.4050001@meteo.fr>

hi all,

Some pbs with Strategy.Refresh :
Imagine the following layer :

var layer = new OpenLayers.Layer.Vector("FIR+Sigmets", {
		strategies : [ new OpenLayers.Strategy.BBOX()
		              ,new OpenLayers.Strategy.Refresh(
				{force: true, interval:  10000  } )] ,
		protocol : new OpenLayers.Protocol.HTTP( {
			url : "./xml/data.xml",
		  	params: { 'key': Math.random()},
			format : myformat
				}),
		styleMap : new OpenLayers.StyleMap(style),
		renderers : [ "Canvas", "SVG", "VML" ],
		projection : map.displayProjection
	});

I noticed *2 pbs :

1/ If i add a control select : selectControl = new 
OpenLayers.Control.SelectFeature(layer), with an open popup on feature 
selection. The pb is that when the layer is refreshed, the popups are 
not erased...The layer changed, and it is not possible to access to the 
layer used to create popup...

2/ In the example, note that the url of protocol.HTTP includes a 
Math.random() key. Refresh process does not seem to generate again the 
key param...

any help during  this hot summer ?

Thank you David,
ok so: isn't it the behaviour of a layer with wrapDateLine = false, i.e. the
default behaviour?

Moreover, I was trying to see the effect of maxExtent property of the map (I
think I have to set it wider to just 1 globe, so to go beyond the IDL), but
nothing changes, even for very small maxExtents.
...So what does the maxExtent stand for?

Piero

Message-ID: <1280309230218-5345406.post@n2.nabble.com>


I'm trying to enable VEMapStyle.Birdseye mode for VirtualEarth layer in my OL
app 
using
if (mapObject.IsBirdseyeAvailable()) {
	                          
mapObject.SetMapStyle(VEMapStyle.BirdseyeHybrid);
}
Birdseye scene displayed, but it seems that panning (moving center) doesn't
work: view changed to some faraway place. 
How can I fix it?

Thanks for your answer.

I added a fresh function that close the popup open on the layer before 
refresh it :
new OpenLayers.Strategy.Refresh(
	{ force: true,
	  interval:  60000,
	  refresh: function()  {
	   if (this.layer && this.layer.refresh) {
	    while( this.layer.map.popups.length ) {
	     this.layer.map.removePopup(this.layer.map.popups[0]);
	    }
	    this.layer.refresh({force: this.force});
	   }
	  }
	 }

Subject: [OpenLayers-Users] Help with color-vector problem ?
Message-ID: <1280311488099-5345442.post@n2.nabble.com>


Hello everyone, I am currently working on creating a map for personal use. In
my code, I can draw regular-irregular polygons -including defining the sides
of the polygons- , lines, points. Also I can navigate the map and modify the
drawings I have drawn -resize, reshape, drag and rotate-. I also wanted to
add the color feature so that I can draw different colored features. I have
implemented the code as following but there are two quite big problems:
Whenever I draw with selected color, all polygons turn into the color of the
last drawn vector's color -in case of refreshing the layer or zooming- and
also I can't modify the vectors in this case -rotate,resize etc.- And as if
this isn't enough, the code doesn't call the color change function in the
context of style but the function I wrote just under the text/javascript
part. And deleteing either one of these causes the coloring feature to be
inactivated. I have been fumbling with this for the past 2 days and it has
become quite frustrating since there are no examples or even tiny bit of
info about coloring vectors. Does anyone have any ideas ? The codes for
color, styling and vector are below: 
var selectedColor;
	function color(value){
		if(value == "purple")
		{
		   selectedColor = "purple";
		}
		else if(value == "blue")
		{
			selectedColor = "blue";
		}
		else if(value == "yellow")
		{
			selectedColor = "yellow";
														
		}
		else if(value == "red")
		{
			selectedColor = "red";
														
		}
		else if(value == "orange")
		{
			selectedColor = "orange";
														
		}
		else if(value == "green")
		{
			selectedColor ="green";
		}
		
		
		return selectedColor;
    }
--------------------------------------------
styling part: 
var value;
var myStyleMap = new OpenLayers.StyleMap(
                        new OpenLayers.Style({
								fillColor: '${color}',
                                strokeColor: '${color}', strokeOpacity: 0.5,
fillOpacity: 0.5},
                                //call attribute of style in order to modify
                         {
                                context: {
                                        color: function(feature) {
										if(value == "purple")
													{
														selectedColor = "purple";
														
													}
													else if(value == "blue")
													{
														selectedColor = "blue";
														
													}
													else if(value == "yellow")
													{
														selectedColor = "yellow";
														
													}
													else if(value == "red")
													{
														selectedColor = "red";
														
													}
													else if(value == "orange")
													{
														selectedColor = "orange";
														
													}
													else if(value == "green")
													{
														selectedColor ="green";
													}	
													return selectedColor;
                                                }
                                }
}));




and the html part that shows options to change colors:
<select id="colors" onchange="color(this.value)">
			 <option value="purple">purple</option>
			 <option value="blue">blue</option>
			 <option value="yellow">yellow</option>
			 <option value="red">red</option>
			 <option value="orange">orange</option>
			 <option value="green">green</option>
		</select>


P.s: if the code is not detailed enough, I can e-mail the actual version.

Thanks and cheers

Thank you David,
ok so: isn't it the behaviour of a layer with wrapDateLine = false, i.e. the
default behaviour?

Moreover, I was trying to see the effect of maxExtent property of the map (I
think I have to set it wider to just 1 globe, so to go beyond the IDL), but
nothing changes, even for very small maxExtents.
...So what does the maxExtent stand for?

Hi, I'm not bringing answers. :)
I can't see the OpenLayers.Layer.OSM class in the API reference, nor it gets
recognized whether I implement it.
Guess the last stable OL version 2.9.1 is not supporting this class yet...?

Hello Piero,

This is my understanding of how wrapDateLine works:

The wrapDateLine property is used by tile layers when determining which
tiles to display.  If your layer contains "wrapDateLine: true", the layer
adjusts it's tile coordinates if the IDL is in the map viewport. If your
layer contains "wrapDateLine: false", the layer will not adjust tile
coordinates. I think that this does not apply to vector layers, only tiled
layers.

I have not had success with setting maxExtent to include multiple globes,
either.  I have only had success setting the map maxExtent to a smaller
extent that the globe, and using restrictedExtent to constrain the map
navigation within that extent.

I read somewhere, and tested too, that this does not have effects on Google
layers. Still no continuous zooming is achieved.

OL developers: is it an available skill now that OL has support for the V3
Google APIs?
Will it ever be?

Thank you.

I want to combine two separate filters using a logical filter, the objective
is to use a comparison filter to set the point radius of a marker from
feature "attribute1" and use another filter to set the color of that marker
from "attribute2". Thanks for the help

Here's what I have

                      var rule = new OpenLayers.Rule({
                      filter: new OpenLayers.Filter.Comparison({
                        type: OpenLayers.Filter.Comparison.GREATER_THAN,
                        property: "attribute1",
                        value: 5

                    symbolizer: {graphicName:"circle",
                                     pointRadius: 7
				     }

                    var rule1 = var rule = new OpenLayers.Rule({
                      filter: new OpenLayers.Filter.Comparison({
                        type: OpenLayers.Filter.Comparison.LESS_THAN,
                        property: "attribute2",
                        value: 2
                    }),
                    symbolizer: {graphicName:"circle",
                                    strokeColor: '#000000',
				    strokeWidth: 1,
				    fillColor: "#0000FF"
				     } 
                    });

                   var rules = new OpenLayers.Filter.Logical({
                                    filters: [rule1,rule2],
                                    type: OpenLayers.Filter.Logical.AND})

These are just some code snippets I have written, any help on how to put
them together would be great

I think you're on the right way.
Maybe you now have to create a rule on the 'rules' logical filter you
created, then add it to the style of the feature layer.
                                    
Think you should read here:

	OpenLayers.Control.WMSGetFeatureInfo with tiled WMS
Message-ID: <AANLkTim6txz5_P4YMKtHXdmtVwbqqupQJcQx4uJq2jfc@mail.gmail.com>

Dear listers,

I have a tiled Mapserver WMS which I use in an Openlayers environment. It
contains a lot of points (polling stations) that are clickable, and a popup
appears with the point info.
The strange thing is: when I click on a single point, I get no results, and
sometimes a dbf error message. But when I click on a place on the map where
there are more points, I do get results (maxfeatures = 2).
I also have the same data in a non-tiled version, and there everything works
fine.
Now my question is: is this a Mapserver problem, or an Openlayers problem?
The tiled WMS map can be found here:
http://speeltuin.nrc-handelsblad.com:8888/TILE_OpenlayersTK2010stembureaus.html
The non-tiled WMS map is here:
http://mapserver.nrc-handelsblad.com/OpenlayersTK2010stembureaus.html

I hope you can help!

I believe it already works in V3 of the api :
http://openlayers.org/dev/examples/google-v3.html

I read somewhere that it still doesn't work in some browsers though
(couldn't find link). I just tried in IE and FireFox and it didn't work.
Safari and Chrome gives you the smooth zoom in though.

Here is the V3 announcement btw :

So should it work

create filterComparison1 for attribute1

create filterComparison2 for attribute2

create filterLogical with above filters

add filterLogical as filter to the rule


var filterComparison1 = new OpenLayers.Filter.Comparison({
    type: OpenLayers.Filter.Comparison.GREATER_THAN,
    property: attribute1,
    value: 5
});

var filterComparison2 = new OpenLayers.Filter.Comparison({

});

var filterLogical=new OpenLayers.Filter.Logical({
        type: OpenLayers.Filter.Logical.AND,
        filters:[filterComparison1, filterComparison2]
});

var rule = new OpenLayers.Rule({

    }),
    symbolizer: {graphicName:"circle", pointRadius: 7}

Hi Paul,
is there a specific place where to put the overwritten prototype?
Because I'm trying to, but the default method is still called.

Thanks.

I do this

OpenLayers.Control.SelectFeature.prototype.myDownfeature = function() 
{
   //your code 
    this.downfeature() 
}

But this only works if you can allow a function rename.

Hi Andreas,

Thanks. That method works, but I was hoping I could get geowebcache to work so that clients that consume data from us can access both maps and getfeatureinfo from the one url. Ideally I would like to have geoserver completely inaccessible from outside the firewall, with geowebcache being the only way to access it. Your suggestion will do the trick for the time being though.

Regards,

Miles

The content of a GetFeatureInfo response is determined by the WMS - you have very little control over what it outputs from the client side apart from applying CSS to it.

Assuming you are using Geoserver, you can create a template for what the getFeatureInfo response should look like either on a global or per-feature type level.

Subject: [OpenLayers-Users] Security issues dealing with openlayers
Message-ID: <000501cb2ee8$87c731a0$2400a8c0@argongra.local>

Hi all,

 

I am not sure if this is the right place to ask this question, but I am sure
many of you have dealt with this problem at one time or another.

 

I am working with openlayers together with Mapserver CGI (caching with
tilecache). I am configuring a public site and I was wondering about the
serious security issues dealing with mapserver instances. I am assuming that
if too many users try to reach my website to view one of my maps
concurrently, or even if a malicious user finds the way too make too many
openlayers requests, my Apache server may eventually collapse. Is there a
way to limit the number of openlayers child threads created
(mapserver/postgis instances) by my server without disturbing in the overall
server performance? Is there a way to bound the maximum number of
mapserver/postgis instances my server can handle? Or even more, is there a
way to deny service to users which overload the system? Any help within this
topic will be more than welcome.

 

Thanks in advance,

 

Manu

Hello, 

I'm working with Geosever (2.0.2). I need to activate a Geowebcache for my

I'm using Openlayers to put the WMS services.

I consulted the documentation in

don't know because don't work.

Any suggestion?

Thank's a lot !

Well I'm doing like Paul suggested, without renaming the function:

OpenLayers.Layer.prototype.getLonLatFromViewPortPx = function (viewPortPx) {
alert('Overwritten!');
}; 

No way.

But if it is the correct way, I'll manage somehow.
Thank you guys!

I'm seeing that functions are not overwritten if the function is not directly
on a certain OL class, but on an inherited class.
I mean, if I overwrite a function in OpenLayers.Layer, it's not seen by
OpenLayers.Layer.Google for example.

Any clues?

Subject: [OpenLayers-Users] Online spatial analysis
Message-ID: <960565.77970.qm@web24904.mail.ird.yahoo.com>

Hi,

I am developing a web based?GIS application. Following tools are used in the 
development:

(1) PostGIS database that contain the exported shape file data (i.e Geometry and 
attribute data) in table form
(2) GeoServer to publish maps and layers as WMS and WFS services
(3) OpenLayers for mapping
(4) Java (JSP) for Server side scripting.

I want to perform online spatial analysis and show it on the map.

(1) Suppose I enter a buffer zone in a textbox, now I want to see how many parks 
are inside that buffer zone near my house. The parks inside the buffer zone 
should be highlighted.

(2) As there can be different types of parks, like national park, muncipal park, 
etc. How to?highlight that area having only?national parks.

The data of parks and houses are stored in the postgresql/postgis database as 
point features.

How to implement it using OpenLayers, GeoServer, PostGIS and if required Server 
side technology like PHP or Java can also be used.

It will be apprecited if some?examples?are posted or links are provided related 
to the stated problem.

Thanks,

Hi,

you should overrite function over implemented class not directly from
OpenLayers.Layer ,

when you overrite  a x functions in OpenLayers.Layer class and if your
implemented class is Google layer  syntax is,

OpenLayers.Layer.Google.prototype.x=function(){
    // your code
}

Message-ID: <784FAC631C0CB14CAE68764151D5DA41081D6998@CORRIOL.icc.local>

Hi list,

 

When OpenLayers.Control.Measure finish to draw a feature, I added to
vectorLayer to avoid to lost it if user draw another one measure. It
happens that last feature appears over the map "strong" because there
are two identical features, one drawned by measure control, and the
seccond drawned when is added to the vectorLayer. I supose that I can
call featureadded event to remove feature added from measure control and
get only the feature added to vectorLayer.

 

Is featureadded the place where to put the code? If yes, how can I
overwrite this function?

 

Thank's in advance.

Subject: [OpenLayers-Users] Spatial filter BBOX limitation?
Message-ID: <1280401802777-5347173.post@n2.nabble.com>


Hello everyone

I'm having a problem to apply a spatial filter. Imagine that I have one
layer with 2 polygons: Polygon1 is inside the BBOX and Polygon2 is outside
the BBOX (not currently visible in the map). I have a second layer with
points where some of them are inside Polygon1 OR Polygon2. Since I only need
the points that are within Polygon1 OR Polygon2 I've applied a SPATIAL
FILTER. The result is achieved, as expected, for the Polygon1 (the points
OUTSIDE Polygon1 disappears) but the points that are inside Polygon2
disappears as well. 

The error doesn't occurs if I have both Polygon1 and Polygon2 inside the
BBOX (both visible in the map).

One possible workaround is not to use the BBOX strategy but then the
performance would be horrible. Can someone give me some ideas on how I could
apply the spatial filter to all polygons of a layer, despite their
visibility?

Thank you very much

Edu

Yes but in geoserver if you open the geowebcache demos, it will show you 
examples of how to call your layers in different formats. You can use 
these examples directly in your code. For a finer definition of the 
layer you'll have to define the geowebcahce.xml yourself. The address 
for geowebcache demos as in docs yourserver/geoserver/gwc/service

openlayers use python script to build the classes together in one file. 
I take it that you want to minimize the openlayers.js and/or remove 
unused classes
Checkout the code from the svn, and you'll find the folder build, which 
contains the the python script and build profiles. At the top of each ol 
class there's one or more @requires tags which indicates class 
dependancy. So in your code add @requires to the ol classes you use and 
they in turn will include their dependancies and so on
Take a look also at related ol trac

	labeling
Message-ID: <AANLkTinrcVZc5EFS9Kcv=AGDsA1mwGGvrNtkff7Ccn2T@mail.gmail.com>

Hi, I'm simply labeling some features with  label : "The time :"+time,
...But I need linebreaks inside the label, because it is getting to
long. I tried things like \n or <br /> ..of course it does not help.

And my second question concerning labels: is there a way to use a
graphic as background-image for labels (it should be something like
the popup bubble) ? Or just a graphic beside the (point)feature in
which I can write some text..that's what I need:)

You have any idea?

Message-ID: <D951CC40C2BF764E834F21094E4A64A76945@ex-mail01.sjwater.com>

Hello all,

I'm encountering an issue in which a certain vector (GML) layer doesn't display when zoomed into my map.  When I'm zoomed out, I have no problems viewing the layer.  Here's my basic setup.  I'm happy to email the gml file to anyone who wants to have a look.  Does anyone know why this would occur?

        options = {
            projection : new OpenLayers.Projection("EPSG:900913"),
            displayProjection : new OpenLayers.Projection("EPSG:4326"),

        };
        map = new OpenLayers.Map('map', options);
        map.addLayer(new OpenLayers.Layer.Google("Google", {
            'sphericalMercator' : true,
            isBaseLayer : true
        }));

Hi Miles-

GeoWebCache supports the WMTS standard.  The WMTS standard defines a 
GetFeatureInfo method (with different semantics than the WMS 
GetFeatureInfo method).  OpenLayers (true) provides a WMTS layer.  I've 
got a patch outstanding to add a WMTS GetFeatureInfo control.  This, in 
my mind, is the way to get feature info from a tile service.

A few tickets need addressing before this would be entirely useful to 
you.  You can watch this one if you're interested:

http://trac.openlayers.org/ticket/2678

I'll try to find some time to finish that up in the near future.

Subject: [OpenLayers-Users] Vector layer returns entire data set
Message-ID: <002e01cb2f9f$91e79550$b5b6bff0$@parkes@pelicancorp.com>

I have a layer showing buildings in Singapore. I have it set up as a WMS
layer, but as I wanted to learn more about vector layers,  am trying to add
the same data as a vector layer just as an experiment.

At the initial zoom level, there are about 20 simple polygons, which
shouldn't be too large for the map.

However, the vector version of the layer is very slow to load, and when I
checked Fiddler and Firebug, found that is returning almost 3MB of data.
Checking the node count in the results against the database confirmed that
it's returning the entire layer.

The code for the vector layer was mostly taken from the OL demo pages. (I
found I had to add the geometryName parameter.)

var lyrBuildingsVector = new OpenLayers.Layer.Vector("Buildings Vec", {
        styleMap: ocStyleMap,
        strategies: [new OpenLayers.Strategy.BBOX()],
        protocol: new OpenLayers.Protocol.WFS({
            url:  GeoServerWFSAddress,
            featureType: "building_3414",
            featureNS:"http://mynamespace/demo",
            geometryName: 'geom_3414'
        })
    });

//Singapore's projection:
var options = {projection: 'EPSG:3414',
                displayProjection: 'EPSG:4326',
		    numZoomLevels: 10,
                maxExtent: new OpenLayers.Bounds(0, 14482.03459,
54313.2955286349, 60381.0195956435),
                units: 'm'
}

This is the  base layer:

var ags_map_service = new OpenLayers.Layer.ArcGIS93Rest(   
                "SNG", 
               	SNG_Server,
                {                                           
                    LAYERS: 'all:0',
                    IMAGESR: '3414',
                    BBOXSR: '3414',

                    FORMAT: 'jpg',                                          
                    TRANSPARENT: false
                },
                {                                                       
                    maxExtent: new OpenLayers.Bounds(0, 14482.03459,
54313.2955286349, 60381.0195956435),
                    units:'m',
                    maxScale: 255104,
                    minScale: 498,
                    projection: proSNG,
                    buffer: 1
                }
            );

The data is in a PostGIS database and runs on GeoServer. However, I was
using SHP files previously, and had the same problem.

Hi Tim,

Thanks for sharing that information. I actually had no idea that the WMTS and WMS getFeatureInfo methods were that different. I'll keep an eye on that ticket for updates.

Message-ID: <1280485471202-5354461.post@n2.nabble.com>


Hello!

Supposing that we have a wms service which converts some vector data (i.e.
gml data about road-network) into raster images,
is it possible to get coordinates of a certain feature (road) using the
standard wms function GetFeatureInfo?

Regards!

Hello,

I believe I'm the data source for the example you are looking at.  The
imagery is servered up via mapserver + PostGIS.  The imagery is stored
on disk with filenames based on their timestamps.  Then the database
stores the bounding box and times of the files on disk.  This may help
you out a bunch:

If it's your service, then you are responsible for the response of the
GetFeatureInfo request.

With MapServer I know, that you can get the geometry of matched features

[shpminx], [shpminy], [shpmaxx], [shpmaxy] 
Minimum / maximum X or Y coordinate of shape extent. Available only when 
processing query results.

But what about a WFS request?

Subject: [OpenLayers-Users] "position: fixed" map
Message-ID: <4C52D618.5080003@gmail.com>

Hi all,

I want a user to be able to bring a map up by clicking a button, and I 
want the map in a fixed position ("position: fixed" in css). This works 
fine on pages that can't be scrolled. If I have a page containing a lot 
of text, and the user scrolls down towards the bottom, then the 
mouse-wheel zoom feature doesn't zoom to the correct position.

As an example, if I take the osm.html example 
(http://openlayers.org/dev/examples/osm.html), add a couple of pages of 
lorem ipsum after the map, and put:

#map {
    position: fixed;

    top: 100px;
    left: 100px;
}

in style.css. Then scroll down to the bottom of the page, and try to 
zoom using the middle mouse button, the place I end up zooming to has 
very little to do with where the mouse is positioned. On the other hand, 
if I scroll to the top of the page, then everything works as expected.

Has anyone met this before, or know if I'm doing something wrong etc.? 
OpenLayers 2.9.1 on Iceweasel 3.0.6.

Thanks,
Ciaran

Subject: [OpenLayers-Users] WMS getFeatureInfo Popup
Message-ID: <1280502245252-5355333.post@n2.nabble.com>


I followed the OpenLayers dev example "Feature info in popup" to get info
about my Parcels layer, adding these lines to my html working page:

info = new OpenLayers.Control.WMSGetFeatureInfo({
	url: 'http://"+host+"/mapserverms4w/mapserv.exe', 
	title: 'Identify features by clicking',
	queryVisible: true,
	eventListeners: {
		getfeatureinfo: function(event) {
		map.addPopup(new OpenLayers.Popup.FramedCloud(
				"chicken", 
				map.getLonLatFromPixel(event.xy),
				null,
				event.text,
				null,
				true
			));
		}
	}
});

The WMS Server reply correctly if I try a manual request via browser, but if
load the openlayers html page and I click over the layer, nothing happens,
and it seems that the event is ignored.

Any ideas?

I guess these lines follow your code...
map.addControl(info);
info.activate();

If you don't specify any url: parameter does it work?

I created this control following this example and it is working well

Subject: [OpenLayers-Users] Vector layer returns entire data set
Message-ID: <4C52ED94.5090908@poczta.onet.pl>

Hi Rohan

1) include the Singapore?s projection proj4js definition :

	<script  src="proj4js/lib/proj4js.js  <view-source:http://mapakrakow.pl/%7Ebbarni/mk4/proj4js/lib/proj4js.js>"></script>
	<script  src="proj4js/lib/defs/EPSG3414.js  <view-source:http://mapakrakow.pl/%7Ebbarni/mk4/proj4js/lib/defs/EPSG2180.js>"></script>

2) Configure proxy server:
	OpenLayers.ProxyHost = "/cgi-bin/proxy.cgi?url=";
	
(geoserver work on port 8080)

3) featureNS - it should be the same URL you provided to GeoServer when you created the namespace.
4) check your stylemap object
5) don't use the namespace prefix in the featuretype.
(http://comments.gmane.org/gmane.comp.gis.openlayers.user/12319)
			{
				url:  "/MyApp/Proxy.ashx",
				featureType: "boundary",
				featurePrefix: "mystore",
				version: "1.1.0"
			})
	

6) use:

srsName: "EPSG:3414",

in Your protocol: new OpenLayers.Protocol.WFS

7) try to add: featurePrefix: and schema: parameters to OpenLayers.Protocol.WFS

Ok I see it, my label is a single pixel. If I max zoom it then goes a way.
Backing up one level it is a single pixel. If I change my font to red the
pixel is red. Why would it do that?

Subject: [OpenLayers-Users] Transition Effect Problem
Message-ID: <AANLkTinn4364E_s+KWcCdsxVb779BUnb=QqaHnaKYpgx@mail.gmail.com>

Hi,

I am using OpenLayers 2.8 and am trying to use the transitionEfftect for two
layers (both are tiled) in the map (one is the base layer and the other is
an overlay). The other layers in the map are not using the transition
effect. I DO see the transitioneffect happening when i zoom in/out sometimes
but sometimes all the tiles are re-drawn over a clean white map area. Why is
this so. I have noticed similar behavior even in the open layers examples
page at
http://dev.openlayers.org/releases/OpenLayers-2.9.1/examples/transition.html.
Even on this page sometimes the image is blurred because of the
transitioneffect until all new tiles are received and sometimes all fresh
tiles are drawn over a clean map area.

Any help or suggestion will be greatly appreciated

Thanks
