Subject: [OpenLayers-Users] How to select WMS layers on one
	OpenLayer.Layer.WMS layer dynamically?
Message-ID: <jdqm64$i3r$1@dough.gmane.org>

Hello,

is there some kind of "layer switcher" which allows me to select the WMS layers 
for one WMS layer?

Of course it would be possible to create one WMS layer for each of the layers, 
offered by the WMS server, I want to use, but IMHO it would be more elegant to 
just need *one* request to the WMS server and let the WMS server do the work.

Yours

Manuel

AFAIK there isn't any specific control, i.e. layer switcher, but it's
easy to do the task you need.
Create a graphic list of your layers, as example using checkboxes (or
a treeview using extjs, or...)
and anytime a checkbox is checked/unchecked, simply call
   wmsLayer.mergeNewParams(...);
passing it an object with only the selected layers { layers:
'myLayer1, mylayer2 '}.
http://dev.openlayers.org/docs/files/OpenLayers/Layer/WMS-js.html#OpenLayers.Layer.WMS.mergeNewParams
then call
   wmsLayer.redwaw(true);

Subject: [OpenLayers-Users] Jquery Mobile - WMSGetFeatureInfo crashes
Message-ID: <1325531869.50192.YahooMailNeo@web121305.mail.ne1.yahoo.com>

Hello,

I have been trying to get the Mobile Jquery Demo to work with my own data.? Currently, I am trying to configure the application so that when a user clicks, the application will identify using WMSGetFeatureInfo as opposed to getting information from the sprinters layer.? Openlayers is crashing when I try to display the results of WMSGetFeatureInfo.? Has anyone had any luck configuring WMSGetFeatureInfo with the Mobile JQuery?? If someone could help me, I would appreciate it.? Thank You!

With help I have thus far:
* The click event to call WMSGetFeatureInfo
* Openlayers calls GeoServer to get WMSGetFeatureInfo
* The click event is registered to call a function named ShowWMSInfo
Unfortunately Openlayers crashes in the ShowWMSInfo, which is where I am trying to display the results from geoserver

Here is the code that I have thus far changed in mobile-base.js
#1? Changed the select control to use WMSGetFeatureInfo


??? //var selectControl = new OpenLayers.Control.SelectFeature(sprintersLayer, {
??? //??? autoActivate:true,
??? //??? onSelect: onSelectFeatureFunction});
// ** updated selectControl code**
??? var selectControl = new OpenLayers.Control.WMSGetFeatureInfo({
??? ??? url: 'http://demo.opengeo.org/geoserver/wms', 
??????? title: 'Identify features by clicking',
??????? layers: [water],
??????? queryVisible: true,
??? ??? autoActivate:true
??? ??? //onSelect: onSelectFeatureFunction
??? });

#2? Registered the recoded select control from #1 to call a function called ShowWMSInfo.


selectControl.events.register("getfeatureinfo", this, ShowWMSInfo);
#3? NOT WORKING - ? On each click the ShowWMSInfo function is called. According to firebug, GeoServer is returning a result for WMSGetFeatureInfo.? However, I cannot figure out how to display the results in openlayers.


function ShowWMSInfo(e) {
??? ??? var html = '<table class="getfeatureinfo">';
??? ??? var html += '<tr><th colspan=2" class="layerTitle">' + "</th><th></th><tr>"
??? ??? if (e.features && e.features.length) {
??? ??????? var val = e.features[0].attributes.id;
??? ??????? document.getElementById('WATER_TYPE').value = val;
??? ??? }
??? ??? return html += '</td></tr>'';
??? ??? return html;
??? }

Add vectorLayer to map perhaps?
map.addLayer(vectorLayer);

Other causes may be that other default controls is activated on your map.
These may be blocking for you select feature control.

If cross origin resource sharing is supported is only determined by
your browser, not OpenLayers. If you can control what your server
provides, you can either set the appropriate
Access-Control-Allow-Origin header and live with the fact that some
browsers don't support it, or use JSONP and OpenLayers.Protocol.Script
to make things work in all browsers. See
http://openlayers.org/dev/examples/cross-origin.html for an example.

This does not seem to be working either.

var state = new OpenLayers.Layer.Vector("K", {

Hi Aparna,
what Arnd wrote is that you can create an OGC filter for your WFS as in

var ogcFilter = new OpenLayers.Filter.Comparison({
     type: OpenLayers.Filter.Comparison.EQUAL_TO,
     property: "id",
     value: someId
});

and then use it in your protocol:

var state = new OpenLayers.Layer.Vector("K", {
                 strategies: [new OpenLayers.Strategy.Fixed()],
                 protocol: new OpenLayers.Protocol.WFS({
                     version: "1.1.0",
                     url: "http://localhost:8085/geoserver/wfs",
                     params: {CQL_FILTER: 'SCHCAT = 3'},
                     featureType: "karf",
                     featureNS: "http://opengeo.org/India",
                     defaultFilter: ogcFilter
                 })
             });

Or have a look here: http://openlayers.org/dev/examples/wfs-filter.js

Thank you for your answers.
Unfortunately it does not work yet...
I've added this to the php providing data:

<some functions here>
if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {
    // return only the headers and not the content
    // only allow CORS if we're doing a GET - i.e. no saving for now.
    if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD']) &&
              $_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD'] == 'GET') {
        header('Access-Control-Allow-Origin: *');
        header('Access-Control-Allow-Headers: X-Requested-With');
    }
    exit;
}
<other code calling functions above etc.>

Otherwise the php code is the same (fetching data and creating a
geoJSON output).

JS code for vector layer looks like this (MyVector is only overloading
drawFeature from Vector):

  var poi = new OpenLayers.Layer.MyVector("Istoriniai", {
      strategies: [new OpenLayers.Strategy.BBOX({resFactor: 1.1})],
      protocol: new OpenLayers.Protocol.HTTP({
               url: "someserver.lt/poi.php?type=monument",
               format: new OpenLayers.Format.GeoJSON({ignoreExtraDims: true}),
           })
       });
  poi.setVisibility(false);
  map.addLayer(poi);

Browser used is firefox 9.0.1 on f16/f15. Everything works just fine
if I'm using a proxy or placing poi.php on the same domain (which is
only possible in development environment).

I will check http://openlayers.org/dev/examples/cross-origin.html to
see if I can use the code/ideas there.

Thank you

Thanks Christoph,

OGC filter is working with the vector layer (WFS, didnot work with the
geojson). Though with more complex filter combinations one has to convert to
CQL and then refresh the map. 

layer.refresh({force:true});

was needed. Thanks to all for your help.

Aparna

In the ne_10m_populated_places_simple.shp I have a lot of points which
indicate a city and its name is into the SHP file.

Now, I want when some user click's in one of this poins, he can read a
message with the name of the city.

Thanks!

I would use the Control.WMSGetFeatureInfo, rather than your own custom 
click handler. It should do exactly what you want, and save you a fair 
amount of typing.

The overviemap is a special map created by the overview control.
But it is still a normal map that can have layers and so also vectors on
top.
To acces the map of the overview control you have to use the ovmap property
of your ov-control

i.e.

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

  var overview = new OpenLayers.Control.OverviewMap();
  map.addControl(overview);
  
  //this is the overview map
  var ovMap = overview.ovmap;

Subject: [OpenLayers-Users] Use single OL file with rotated labels in IE8 
Message-ID: <1325754730.15469.YahooMailNeo@web29702.mail.ird.yahoo.com>

Hello list,
I use Openlayers 2.11 and applied a modification to rotate labels (from http://osgeo-org.1803224.n2.nabble.com/How-to-rotate-a-label-in-IE-td4834932.html).
Everything works fine (multifile in chrome, firefox, IE8; single file in chrome, firefox), but if I use the Openlayers.js single file in IE8 no labels are displayed. There is no error message. While debugging I detected one difference:
With multi file the label object is created after 

??? ??? ??? this.textRoot.appendChild(label);
??? ??? ??? label.appendChild(textbox);?? 
??? ??? ??? label.appendChild(path);
So label has fields like 'stroke' and 'coordorigin'. E.g. 'coordorigin' has the attributes 'x' and 'y'.

With single file these label fields are not created. Later on the 'coordorigin' will be set. But instead of label.coordorigin.x=100; labelcoordorigin.y=200; there is only an entry label.coordorigin="100 200"; - so if I call label.coordorigin.y I get 'undefined'.


I think this could be the reason for the missing label. But why is the label object not created correctly?


I found out that there was a similar problem with labels and single file in IE8 (http://trac.osgeo.org/openlayers/ticket/1910), but this patch is already included.

Has someone another idea?

Thanks,
leene

Subject: [OpenLayers-Users] Filtering a vector Layer
Message-ID: <CAJSds0Nfu5XSJima+2buMUf1JH9g9BT1Fnbs6Fae2VJL8sm=Jw@mail.gmail.com>

Finally, was able to filter the vector layer,. The biggest problem was to
use multiple values and/or multiple filter options and could not create
permulation combination of OGC filters(logical, comparison, ..). This
seemed rather difficult at first. Eventually created CQL filters
which were converted. This is the layer

var state = new OpenLayers.Layer.Vector("Karnataka", {
                strategies: [new OpenLayers.Strategy.BBOX()],
                filter:"",
                protocol: new OpenLayers.Protocol.WFS({
                    version: "1.1.0",
                    url: "http://localhost:8085/geoserver/wfs",

                    featureType: "karf",
                    featureNS: "http://opengeo.org/India"

                }),


            });

and then logical OR or Logical AND was wrapped with comparison Filters and
converted to OGC.

Hello

  The only missing part in php code was handling of non preflight, so
the final code in php should be like this (note the "else" part):

 if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {
    // return only the headers and not the content
    // only allow CORS if we're doing a GET - i.e. no saving for now.
    if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD']) &&
              $_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD'] == 'GET') {
        header('Access-Control-Allow-Origin: *');
        header('Access-Control-Allow-Headers: X-Requested-With');
    }
    exit;
 } else {
   header('Access-Control-Allow-Origin: *');
 }

  And now it works.  Thank you for help!

Message-ID: <1325847343996-7157998.post@n2.nabble.com>

Hi List

I am trying to initiate popups for point features rendered via MapServer /
PostGIS. The code is based on the openlayers example:
http://openlayers.org/dev/examples/getfeatureinfo-popup.html

Initially using firebug the "map" parameter was not being passed to the
request and I have managed a work around by adding the vendorParams
variable. This now produces a getfeatureinfo request that when entered
manually works perfectly and returns the requested information.

I Am now however getting the Firebug error: "this.size is null" followed by
the line:

if((origTL.x+this.size.w)>(mapSize.w-t....paddingForPopups.right-this.size.w;} 


My Code is listed below:

     info = new OpenLayers.Control.WMSGetFeatureInfo({
           url: '*HOST*/cgi-mapserv/mapserv?',
           vendorParams: {
                         map: 'mapfiles/fhf_test/booth_points.map'
                        } ,
            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();


Any help much appreciated.

Mike

Subject: [OpenLayers-Users] Introducing mapshup
Message-ID: <CALP+WC_k-Ci=r6O9-qGy40DSPgOwegUb-vDOVmZSKH3KYvtx6w@mail.gmail.com>

Dear OpenLayers users,

Last year i presented jeobrowser application. As of today, this
application is no more and it is replaced by the mapshup application
framework.
This application is released under the opensource CeCILL-B license
(basically a kind of BSD licence)
and source are immediately available at http://code.google.com/p/mapshup/

A running demo is available at http://engine.mapshup.info
(hidden functionality : try to drag&drop a valid file or layer url
(wms, wfs, csw, etc.) on top of the map and the application will try
to automatically add it to the map :)

Best regards

Jerome

Subject: [OpenLayers-Users] strange behavior with wrong click event
	coordinates and drag pan
Message-ID: <695DB8FA-ABBB-40DC-AC17-085D9B314F96@gmail.com>

I am experiencing a strange behavior that perhaps someone can help me troubleshoot. I am trying to make some custom mods to OpenLayers 2.11 -- nothing fancy, nothing in the JavaScript, only some of the buttons and images. So, I made a copy of my OL installation, and called it OpenLayers-copy, and replaced my OL script line in my web page like so

    - <script type="text/javascript" src="path/to/lib/OpenLayers-2.11/OpenLayers.js"></script>
    + <script type="text/javascript" src="path/to/lib/OpenLayers-copy/OpenLayers.js"></script>

    var map = new OpenLayers.Map("map", {
        "controls": [
          - new OpenLayers.Control.LayerSwitcher(),
          - new OpenLayers.Control.Navigation(),
          - new OpenLayers.Control.PanZoom(),
          + new OpenLayers.Control.LayerSwitcher({
          +     "roundedCornerColor": "rgba(0,0,0,0.8)"
          + }),
          + new OpenLayers.Control.ZoomPanel(),    
            new OpenLayers.Control.MousePosition({
                  "div": document.getElementById("coords"), 
                  "numDigits": 2
            })
        ],
        "projection": new OpenLayers.Projection("EPSG:900913"),
        "displayProjection": new OpenLayers.Projection("EPSG:4326"),
        "units": "m",
        "maxResolution": 156543.0339,
        "maxExtent": new OpenLayers.Bounds(-20037508, -20037508, 20037508, 20037508)
    });
    
    map.events.register("click", map, collections);
    
    "collections": function(e) {
        var lonlat = map.getLonLatFromViewPortPx(e.xy).transform(
            new OpenLayers.Projection("EPSG:900913"),
            new OpenLayers.Projection("EPSG:4326")
        );
        
        .. do something with lng/lat ..
    }


That is the extent of my OL changes. I am now seeing the following two behaviors that are foxing me --

1. The mouse display shows the correct mouse position in lng lat, however, the actual point clicked on (for further querying is off by several tens of degrees. For example, if I click at [-78.71, 43.33], the actual point calculated by the click event listener is [-61.45, 61.61]. Why?

2. I am unable to drag and pan the map. On the other hand, if I bring back Control.Navigation and Control.PanZoom then I am able to drag pan the map. I want to be able to drag pan the map, but I don't want to show the PanZoom controls. How can I achieve that?

Many thanks,

I changed the OL library to the original, as downloaded from OL servers. The click reported by the mouse position display is off from the click reported by the map listener even with the original OL library, albeit, by a smaller amount. For example, I clicked on [-78.35, 43.45] as shown in the mouse position display. The click event reported [-77.97, 49.61]. A very small lng shift but a fairly large lat shift.

This is quite perplexing, and definitely very erroneous.

OL maps are being displayed with white grid lines around map tiles in groups
of 2x3, 3x3 and 4x3 tiles (depending on scale) in Google Chrome only -- at
least the same issue does not exist in FireFox or IE.  It looks like Chrome
was updated to v16.0.912.75 yesterday at 15:00 EST, but this issue occurred
earlier in the day than that for me (also occurred on v16.0.912.63).  It
occurs for Bing base maps, Google, etc. and does not occur in Chrome when
hitting maps.google.com or www.bing.com/maps directly.  My map was created
w/ default options, i.e. a simple "var map = new OpenLayers.Map('map');" and
then added Bing/Google layers.

Has anyone else experienced this?

Hi.

Big thanks for application! But my colleague reported me application not
works. See screenshot:

Hi Denis,

Thank you for your feedback. Application automatically detects the
browser lang. I completely forget to put the russian translation on
the server that's why your friend get an error. It's corrected now
(everything should be displayed in english).

Regards

Jerome

Hi,

are you using fractional zoom values? What does map.getZoom() return?
If it's an integer, you should not be seeing these gaps.

Andreas.

Subject: [OpenLayers-Users] OL vector/wfs trouble with GeoServer
Message-ID: <1325880902572-7159749.post@n2.nabble.com>

Hello, my first post on an online forum, so I appoligize if I fail at the
info!

My setup:

Tomcat 7.0.22, localhost:8082
GeoServer 2.1.3, hosted via Tomcat (also :8082)
Oracle XE/Apex 4.1, running via embedded XDB gateway on :8080
Openlayers 2.10 (tried 2.11, not sure if that was the issue, currently back
on 2.10)
Python 2.7 (for my proxy script)
Using Firefox/Firebug for review

I'm attempting to offer a layer of point geometries from my XE DB as a
Vector layer on my map.  The layer displays fine in Geoserver
(workspace:BETA_ORCL, layer:CC_COUNTRIES); I can preview in all formats.  I
had first attempted the GeoServer Proxy (proxy-2.1-SNAPSHOP), but was
unsuccessful and deleted the .jar from my web-inf/lib.  Next, I tried the
proxy.cgi provided by Openlayers - it was origionally unsuccessful as well
(the section that rendered the 'qs' "QUERY_STRING" as an array set was
truncating my url request at the first &...I replaced with an lstrip('url=')
to clean my url instead), and I can successfully pass a getFeature request
using the proxy by manually inserting the url (proxy and getFeatures call)
into a browser; it returns what seems to be a valid xml of my feature set.

All this leads me to believe my Geoserver can offer this layer as a wfs
layer (wfs is enabled, getCapabilities checks out, etc.) through the proxy. 
Here's my layer call from javascript:

var countryLayer = new OpenLayers.Layer.Vector("WFS", {
    strategies: [new OpenLayers.Strategy.Fixed()],
    projection: new OpenLayers.Projection("EPSG:4326"),
    protocol: new OpenLayers.Protocol.WFS({
      url: "http://localhost:8082/geoserver/wfs",
      featurePrefix:"BETA_ORCL",
      featureType: "CC_COUNTRIES",
      geometryName: "CENT_GEOM",
      featureNS: "http://betaora.org",
      schema:
"http://localhost:8082/geoserver/wfs?service=wfs&version=1.1.0&request=DescribeFeatureType&typename=BETA_ORCL:CC_COUNTRIES", 
      srsName: "EPSG:4326",
      version: "1.1.0"
      })
});

When the page renders, the only activity I see in the GeoServer logs is the
request for WMS tiles (my base map, which displays fine).  Nothing at all
for WFS layer, no errors...nothing.  In FireBug, I get two warnings on the
console (regarding the xml.js and v1.js for openlayers) about null objects,
but no errors.  On the Net panel, the activity reads:

URL: OPTIONS cust.cgi?url=.... (on mouseover, changes to full
http://localhost:8082)
STATUS: 200 OK
DOMAIN: localhost:8082
SIZE: 0
Remote IP: localhost:8082

The response is completely empty.

I'm concerned because the net activity in Firebug for WMS layers starts with
POST/GET (vice OPTIONS); does this indicate the problem?

Also unsure of the paramater calls for Protocol.WFS - I've seen SOOO many
combos that all claim to work (using/not using featureNS, schema, etc.)...do
I have it right?

Finally; my Vector layer does create.  It is added to the layer selector,
and is under the dom objects.  However, there are no features; nothing
displayed, nothing in the feature array, and the final two <g> elements
(vroot and troot) have no children.  If I manually add a feature (using the
markup controls), they are successfully added to the map and dom.  Which
makes me think the layer IS working...just not getting data from Geoserver.

Any help is SERIOUSLY appreciated...I'm red-eyed from scouring forums, and
would love to get on with my life.  Thanks!

Neil

but when i update the data on the server they will not show soon. 
Shift+F5 (reload) will them not show soon. it takes some times.

can anybody tell me a possiblity to show intime the update-data ?

Phew.... solved this one. It was user error (a faulty call in the html5 location sensing routine).

The click reported by the mouse position display is off from the click reported by the map listener even with the original OL library, albeit, by a smaller amount.

I think the problem is that you are using Oracle APEX ;)

I get the same thing but only when viewing from localhost. Once I 
uploaded to the server the tile borders went away.

Dear Friends

 I support the right way to encode a WFS service generated by the ArcGIS Server 9.3.1
 to test intersection.
 
I tried several ways but I do not visualize the polygons of the WFS service.
 I managed to do so with Geoserver WFS and Mapserver, but I lack of ArcGIS Server.
 I am using Protocol.WFS class (as well as OpenLayers.Layer.Vector) but I think I'm the missing options for proper charging.
 
The route url is: http://192.168.1.98:8087/ArcGIS/services/SERNANPWFS/MapServer/WFSServer.
 The layer is called "ANPNacional", is composed of objects from a shapefile polygons,
 I have also:
 The route url is: http://192.168.1.98:8087/ArcGIS/services/SERNANPWFSFGB/GeoDataServer/WFSServer
 With Feature class: ANPNacional from File Geodatabase .
 If you're in a SDE geodatabase as well as serious.
 
I say goodbye to waiting for your help.

Then maybe your browser view is zoomed? Try pressing Ctrl+0 (or Cmd+0
if it's on a Mac) to set the zoom to 100%.

I can simply not drag the map around. I want to be able to drag the map without showing the pan controls on the top left. How can I do that?

Dear OpenLayers users,

Last year i presented jeobrowser application. As of today, this
application is no more and it is replaced by the mapshup application
framework.
This application is released under the opensource CeCILL-B license
(basically a kind of BSD licence)
and source are immediately available at http://code.google.com/p/mapshup/

A running demo is available at http://engine.mapshup.info
(hidden functionality : try to drag&drop a valid file or layer url
(wms, wfs, csw, etc.) on top of the map and the application will try
to automatically add it to the map :)

Best regards

Jerome

If your map's projection is not EPSG:4326 and not EPSG:900913 or one
of its aliases (like EPSG:3587), you'll have to include proj4js and a
projection definition file for your map projection to make this
transformation work.

Make sure your csv.phtml sends proper cache control headers (or maybe
an ETag header in your case), and things will be fine.

Subject: [OpenLayers-Users] Drawing overlays problem on Chrome and Win7
Message-ID: <4F0AE62C.4010007@ruptela.lt>

Hi, we are encountering drawing problem with overlays: strange artefacts 
are drawn on the map. Looks like something like fill shape function is 
broken and instead of filling required shape it fills big part of the 
screen. Screenshot here: http://oi40.tinypic.com/2lo5440.jpg
It happens occasionally only on Windows 7 and Chrome browser (maybe 
specific to hardware too?). Never on Firefox, or Linux or Windows XP. 
Not easy to reproduce, but it happens constantly, it's not a once in a 
lifetime occurrence.

Google did not help, or I don't know what to look for. Has anyone else 
experienced something similar? Should I provide more info, what exactly? 
Any ideas or suggestions?

Thanks in advance,
Arunas Noreika

Hi there,

I have had the exact same problem. I do think it's an issue with
Chrome, as when I tried the nightly "Canary" build I don't get those
problems. Have a go at that
(http://tools.google.com/dlpage/chromesxs) and see what happens. If
you're in luck then the next chrome update should fix it.

Hi,

Cool stuff. Very interesting extension for OpenLayers. 

I have created a more complex example to test some functions (Boundary,
Buffer, Centroid, ConvexHull, Union, Intersection, SymDifference) of the
jsts topology suite.

http://gis.ibbeck.de/ginfo/apps/OLExamples/OL210/JSTS_Example/jsts_example.a
sp

JSTS is easy to integrate to OpenLayers and the results are very impressive.

The page is based on the new release JSTS 0.11.1.

Hey OpenLayers folks!

JSTS 0.11.0 was just released:
https://github.com/bjornharrtell/jsts

JSTS is now a relatively complete port of JTS Topology Suite and is quite
stable, at least according to the 497 passing tests.

Some live examples of buffer,?overlay?and?triangulation operations:

Subject: [OpenLayers-Users] the right way to get lon/lat from pixel
Message-ID: <2C67DAD3-DF41-4995-8B29-ED710203B850@gmail.com>

I was using the following code without any errors

    [A]

    var lonlat = map
        .getLonLatFromViewPortPx(e.xy)
        .transform(proj.google, proj.latlng);

however, I can't find any reference to the above methods anymore in the API docs. On the other hand, I found the following commands, so I changed my code accordingly

    [B]
    
    var lonlat = map
        .getLonLatFromPixel( this.events.getMousePosition(e) ).
        .transform(proj.google, proj.latlng);
    
The above works well too, but I just want to confirm if [B] is indeed the way to do it, and if the method in [A] is deprecated.

Dear OpenLayers Users

Just wondering if it is possible to use complex symbology for line vector features, such as double-lines?

Many thanks,

[B] is the right way to do it - it uses an API function, whereas [A]
uses an internal function.

Subject: [OpenLayers-Users] Overlay WMS layer on OSM
Message-ID: <1326190262614-7171504.post@n2.nabble.com>

Dear all,

Below is the code of a very simple map that pretends to overlay a WMS layer
on OSM. I have a local MapServer instance from which I add the same layer in
two different ways: as a base layer and as an overlay. As a base layer the
WMS data is shown without trouble. As an overlay nothing is shown, just the
pink void tiles with the missing image icon. Using Firebug I can verify that
when I turn the overlay on no HTTP request is being sent, thus it must be
something wrong with the code.

This is going on with OpenLayers 2.11, btw. Any help appreciated, thank you,

Lu?s

Hi Luis,

I think EPSG:3785 is deprecated. You should use EPSG:3857 instead

Try

selectControl.setLayer((selectControl.layers||selectControl.layer).concat(newLayer));

where newLayer is the layer you want to add.

I have a problem identifying Objects on my OpenLayers map. I have added the control-definition for the WMSGetFeatureInfo 'control' and activated it, but somehow, nothing happens when I click on anything. For debugging, I have implemented an alert() call, but no popup shows up so I know it's not a problem with coordinates or something, but a fundamental problem.

If i change a features symbolizer angel, and position.
How do i make the changes visible on the layer?

If i just call drawFeature, or redraw layer, the old icons stay on the
map..... it's getting a mess.

Do i really have to remove and than add the features every time i edit its
attributes?

Hi, 

You can access the mouse modifier through /window.event/ object.

Example: 

myLayer.events.on({
  
  //...

  "featureselected": function(evt) {
     if (window.event.shiftKey)
        alert("shift pressed");
     if (window.event.altKey)
        alert("alt pressed");
     if (window.event.ctrlKey)
        alert("ctrl pressed");
  },

  //...
});

Good luck,
Florenta Poasca

OpenLayers are you using, and on which browser?

Subject: [OpenLayers-Users] cant select vector feature under label in IE8
Message-ID: <1326231137567-7173892.post@n2.nabble.com>

I have a WFS vector layer with a style/stylemap that defines a label.
If I try and select a feature that is under a label in IE8, nothing happens.
When I do the same in Firefox 9, the feature gets selected.
I am using OpenLayers 2.11 and GeoServer 2.1.2
Anyone else run into this?

Subject: [OpenLayers-Users] markers in vector layer not displaying
Message-ID: <1326242645639-7174448.post@n2.nabble.com>

I'm having a problem displaying markers in a vector layer.  If I change my
styleMap to be default OL graphics (and not markers) then it works fine. 
When my styleMap is the marker styleMap, if I view the properties for my
map.layers.layer.styleMap.styles.default.rules.0.symbolizer, the value of
'externalGraphic' is correct.  And in fact, as a troubleshooting option I
used the fully-qualified URL to the graphic file and that same URL displays
fine in a browser.  The features in my layer are all using a renderIntent of
'default'.   I've also set the graphicZIndex on my styleMap to 100, but
still no markers (in IE, FF and Chrome).

Here is the code in the order executed:

Hi @ all,

I'm new on this list and the developing with openlayer. I hope, that list is
the right way to get a solution for my problem. I have take a look on many
other list, for this theme, but i hope the fastes way for a solution is, to
get the information from the developers.
Ok, i use the version 2.11 of OpenLayer on windows XP in a MS
Internetexplorer version 8. My problem is, after i use the
"OpenLayers.Control.DragFeature" in my map, to move my POI, the left click
get lost and the "OpenLayers.Control.SelectFeature" can't catch them.
Exactly the "clickFeature" in the "OpenLayers.Control.SelectFeature" is not
called and i get a square as mouse pointer? 

Has anyone a idea where is the error??

Thanking you in anticipation, 
Tilo

Hello All,

I know this topic has been thoroughly discussed, but bear with me.

I have a kml layer with the url appended with a ?random="+Math.random();
The kml also has a refresh strategy.

The kml file is on the web server and is updated periodically by
another process, but the name always renames the same.

What I'm seeing is that the random number isn't changing. Should the
refresh strategy do this? Do I need to destroy the layer and recreate
it in another way to flush it out?

Regards,

Toby

Hi solve it!

To avoid this error it's important add the 'vendorParams' like this example:

info = new OpenLayers.Control.WMSGetFeatureInfo(
  {url: 'http://localhost:9000/cgi-bin/mapserv.exe',
   title: 'Identify features by clicking',
   layers: [Layer1, Layer2],
   queryVisible: true,
   *vendorParams: {map: '/ms4w/apps/mapserv-demo/mapfile.map'}*,
   eventListeners: {'getfeatureinfo': function(event) {
                                                     map.addPopup(new
OpenLayers.Popup.FramedCloud("chiken",


map.getLonLatFromPixel(event.xy),
   null,
  event.text,

                                                      null,
   true));}});
  map.addControl(info);
   info.activate();

Dear Friends

 I have a problem that can not be due.

 I have an application that loads fine in IE 8 with WMS layers and WFS Internet and created mine.

 The problem is that when I try to do with Firefox 9 and Firebug 1.9 displayed none of the WFS layers.
 Only WMS layer. May be due to this?

 I say goodbye to waiting for your prompt help.

Figured this out.  It was the way I was creating my vector features (which I
just noticed was the only part of my code that I didn't include in my
original post).  Basically the feature properties were applied directly to
the feature object instead of to the feature.attributes object, and the
styleMap rules look at feature.attributes.property.

Subject: [OpenLayers-Users] OpenLayers polygon fill on IE has black shading
 after setting opacity
Message-ID: <1326310960520-7177631.post@n2.nabble.com>

I apologize up front, but this is a cross-post from gis.stackexchange.  I
asked the question there, w/o much response, so I think this may be an OL
bug rather than a "how do I use it" question.  I'm going to duplicate the
post here and also available at 
http://gis.stackexchange.com/questions/18677/openlayers-polygon-fill-on-ie-has-black-shading

----

I have an odd problem on with OpenLayers on IE6, IE7 and IE8.  A newly drawn
polygon has odd black shading.  In fact, even the line (stroke) has the same
black outline.

Works great in Firefox, Chrome, Safari and even IE9.

I've tried everything from creating my own stylemap and symbolizers, to
removing all styles and using default layer, and it still has a problem.  

And to add to the puzzle, if you draw a second feature and intersect with
the first, the intersected area has *perfect* colorization/rendering.  

I've tried changing the basic style to have a different color (say blue) but
then the color is again the base blue plus the black shading/fill attached
to it.

http://osgeo-org.1803224.n2.nabble.com/file/n7177631/Uk1KH.png 

Have run the basic drawing example,

Edit 1/10 5p PST

I was finally able to create a stripped-down sample that reproduce the
error.

I wrote a page that accepts a URL param to enable the bug, and it'll be
broken in IE8,7,and 6.  All you have to do is draw a polygon, and you'll see
that it comes out black

http://dl.dropbox.com/u/47684/nc4/debug/RenderTest.html?break=1

And here's the source:

    

As you can see, just setting the layer OPACITY will break it. And this
actually breaks on IE6 and 7. It works on 8, but I have compatibility mode
set to 7, so yes that makes it break on 8.  

Why setting opacity is breaking?  I've traced the code down to `Util.js` and
the `modifyDOMElement` function, and it *looks* to be ok.  But... ?

Thank you.

Hi,

this is a bug in IE, and there doesn't seem to be a known workaround:

I found a similar ticket in OL's stack as well.  I'm guessing it's the same
issue.

http://trac.osgeo.org/openlayers/ticket/2810

And it'll probably be left unresolved if it's in the guts of IE and not OL.  

Thanks.

Hi,

This example may help you:
http://openlayers.org/dev/examples/hover-handler.html

BTW, it's recommended not to use Markers but to use a Vector layer with 
your features styled with an externalGraphic. Example here: 
http://openlayers.org/dev/examples/marker-shadow.html

Cheers, Roald

Hi,
I'm trying to create map with simple route planner. I need only to draw
route between two places (which coordinates I know) without text information
or anything. I find openrouteservice.org so I would like to use it in my
map. My idea was XMLHttpRequest, but openRouteService doesn't generate XML.
Do you have any idea how to use this service in my map? Is it evan possible?
Or any other idea how to create route planner in OL? :)

Thanks a lot
Dan

Hy all,

I've tried to install the ol4jsf proxy but i got some issues

Geoserver port : 176.31.233.151:8080

ol4jsf-proxy.xml:
<?xml version="1.0" encoding="UTF-8"?>
<ol4jsf-proxy>
    <use-environment id="desenv" />
    <environment id="desenv">
        <description>Development Environment.</description>
        <resources>
            <resource name="wms">
                <url>http://176.31.233.151:8080/geoserver/wms</url>
                <authentication>
                            <username>admin</username>
                             <password>geoserver</password>
                 </authentication>
            </resource>
        </resources>
    </environment>
</ol4jsf-proxy>

Geoserver strats correctly.

When I try the get capabilties :
http://176.31.233.151:8080/geoserver/OL4JSFProxy/wms?service=WMS&request=GetCapabilities

Geoserver returns me an error 400.
I would like to know what is the url to use the proxy ?

thanks a lot in advance

Hi,

Are you using a JEE 6 server? otherwise, you have to add the servlet
mapping in web.xml:

    <servlet>
        <servlet-name>OL4JSFProxy</servlet-name>
        <servlet-class>org.ol4jsf.proxy.servlet.OL4JSFProxy</servlet-class>
        <load-on-startup>0</load-on-startup>
    </servlet>

Best regards,

Robert

Subject: [OpenLayers-Users] IE 8/9 Click Handler Single Only triggered by
	Double
Message-ID: <9C37154DC7C8074FBC34214363755B7C6593E4@ITB-SVR-01.itbeyond.local>

I have been bashing my head against the wall and I think the problem is
in the Click Handler. I am using 2.11 but the problem also is visible in
http://openlayers.org/dev/examples/click-handler.html - using IE if you
select single only you get a double click event showing as a click - I
think this is wrong and it was not the way it used to be in versions
past. Has an issue resurfaced or do I need to do something else to get
double click not triggering a single click in IE.

 

I am using single to run an AJAX query to return features at the click
and I also use the Navigation control to handle double (left & right )
zoom in/out. I would have thought this typical so I am not sure why my
double click in IE is triggering a DB query.

 

Any help would be appreciated.

David Martin

Subject: [OpenLayers-Users] Drawfeature with multiple vector layers
Message-ID: <1326467947520-7184326.post@n2.nabble.com>

hey guys,

i like to draw polygons on a map, but it is important that i have several
levels. So my idea was to add a vector layer for each level. to change
between the layers i use the " map.removeControl(controls[key]);"  function
to remove all controls needed for drawing and re-add the controls with the
new selected layer. So my problem is now, that all works fine with the
initalized layer, but when i change to annother layer it the drawing feature
behaves strange and it is not possible to draw new polygons. So please help
me how i can use the drawfeature Control with multiple layers.

My pseudo Code:
//create multiple layers: one for each level
        var styleMapL1 = new OpenLayers.StyleMap({fillColor: "green"});
	vlayer1 = new OpenLayers.Layer.Vector("Layer 1", {styleMap: styleMapL1});
	layerArray[1] = vlayer1;
	var styleMapL2 = new OpenLayers.StyleMap({fillColor: "red"});
	vlayer2 = new OpenLayers.Layer.Vector("Layer 2", {styleMap: styleMapL2});
	layerArray[2] = vlayer2;
	var styleMapL3 = new OpenLayers.StyleMap({fillColor: "blue"});
	vlayer3 = new OpenLayers.Layer.Vector("Layer 3", {styleMap: styleMapL3});
	layerArray[3] = vlayer3;

        map.addLayers([vlayer1, vlayer2, vlayer3]);

        this.addControls(3);

//this method is called when i want to change the layers 
function switchControls(layerIndex)
		{
			this.removeControls();
			this.addControls(layerIndex);
		}
		
		function addControls(layerIndex)
		{
			if(layerIndex != null)
			{
				var layer = layerArray[layerIndex];
				controls = {
					    polygon: new OpenLayers.Control.DrawFeature(layer,
OpenLayers.Handler.Polygon)	 
					};

					for(var key in controls) {
									
					    map.addControl(controls[key]);
					    controls[key].activate();	
					    					    
					}
				
			}
		}
		function removeControls()
		{
			for(var key in controls) {
				
			    map.removeControl(controls[key]);						    
			}
			
		}


Greetings Peter

Subject: [OpenLayers-Users] Cartographic coordinates with Google Maps
Message-ID: <1326469595628-7184427.post@n2.nabble.com>

Dear all,

Bellow is the code of a simple map using a Google layer with the
MousePosition control. Even though I'm passing the 900913 projection for the
map projection and the map displayProjection properties the coordinates
shown in the MousePosition are Geodetical (lat,lon in degrees) instead of
Cartographic (x,y in meters). What am I missing?

Thank you,

Lu?s

function initMap(){

    map = new OpenLayers.Map("myMap",{
		projection: new OpenLayers.Projection("EPSG:900913"),
		displayProjection: new OpenLayers.Projection("EPSG:900913"),
		units: "m"
	});

	map.addControl(new OpenLayers.Control.MousePosition());
	map.addControl(new OpenLayers.Control.LayerSwitcher());

	var gphy = new OpenLayers.Layer.Google(
        "Google Physical",
        {type: G_PHYSICAL_MAP}
    );

    map.addLayers([gphy]);

}

Subject: [OpenLayers-Users] IE 8/9 Click Handler Single Only triggered by
	Double
Message-ID: <9C37154DC7C8074FBC34214363755B7C6593DA@ITB-SVR-01.itbeyond.local>

I have been bashing my head against the wall and I think the problem is
in the Click Handler. I am using 2.11 but the problem also is visible in
http://openlayers.org/dev/examples/click-handler.html - using IE if you
select single only you get a double click event showing as a click - I
think this is wrong and it was not the way it used to be in versions
past. Has an issue resurfaced or do I need to do something else to get
double click not triggering a single click in IE.

 

I am using single to run an AJAX query to return features at the click
and I also use the Navigation control to handle double (left & right )
zoom in/out. I would have thought this typical so I am not sure why my
double click in IE is triggering a DB query.

 

Any help would be appreciated.

David Martin

I use controls[i].destroy() to get rid of the controls

Message-ID: <0C3DFBD9-3168-435C-9C7A-528D870069D2@gmail.com>

I am trying to accomplish the following, and would appreciate advice on how to go about doing it --

1. the user click,click,click... double-clicks to create a polygon;

2. the map zooms to the polygon so that the polygon occupies the left half of the browser window.

Here is my attempt to draw the interface --

|                 .                |
|                 .                |

|                 .                |
+----------------------------------+

so, once a polygon is drawn, the map zooms so the drawn polygon is centered to its full extent within A above.

Suggestions welcome. Many thanks,

Subject: [OpenLayers-Users] SelectFeature onUnselect called for nested IE
	elements
Message-ID: <1326492718309-7185898.post@n2.nabble.com>

Hello, 

I have a custom popup I'm creating that has some buttons on it - I want the
user to be able to hover over my popup and push a button. This works great
in Chrome, but nested elements in this popup in IE cause the unSelect
function to be called, closing the popup. 

I tried to check if the mouse is within the popup with some additional event
handling, but in addition to being a messy solution, this wasn't working
(the events weren't firing and/or unSelect wasn't being called after the
mouse really left the popup). 

What is the correct way to handle this?

Thanks in advance, 
Craig

Hi,

register "featureadded" for the layer and create a zoom function

function zoomToLeftHalf(evt)
{
    var arrB = evt.feature.geometry.getBounds().toArray();
    var dx = arrB[2]-arrB[0];
    var bounds = new OpenLayers.Bounds(arrB[0], arrB[1], arrB[2]+dx,
arrB[3]);
    map.zoomToExtent(bounds);
}
map.layers[2].events.register("featureadded", map.layers[2],
zoomToLeftHalf);

so, once a polygon is drawn, the map zooms so the drawn polygon is centered
to its full extent within A above.

Suggestions welcome. Many thanks,

 TileCache wrapDateLine has pink tiles
Message-ID: <97FDCEA6D905154D94E20D02312C8A310D92F37869@mse18be1.mse18.exchange.ms>

Hi, all.  I just grabbed the latest and greatest OL from github and see that OpenLayers.Util.onImageLoadError is no more.  One thing I noticed off the bat is that my TileCache layers (wrapDateLine : true) show pink tiles outside of the usual -180,-90,180,90 bounds.  That used to be handled by the onImageLoadError, but I'm not sure where to look now.

I can reproduce this behavior in the tilecache.html example by commenting out the map's resolutions (so you can zoom way out) and adding wrapDateLine : true to the layer's config.  Not having the wrapDateLine works as advertised . . . no pink tiles.  But having it seems to break something.

Am I missing something obvious?

TIA.

Hey,

Thanks for the info, it seems to work quite well (a minor problem are
different output sizes in each browser if size is not expicitly specified)
except for IE9 where the icon just does not show up. 
I modified the GwtOpenLayersShowcase Labeled Features showcase for testing
(it uses a vector layer).
Since IE9 normally supports at least the most important subset of SVG
(tested it by rendering a simple SVG file in IE9), I wonder what might be
the issue with it. Is it maybe because openlayers assumes SVG is not
supported in IE and just takes a detour via VML for rendering (which seems
to fail in case of single SVG files)?

Regards,
fatzopilot

Hi,

to style the way tiles with unavailable images look, modify the
.olImageLoadError css class, e.g. like this:

.olImageLoadError { display: none; }

Now for the correct usage of wrapDateLine: true - it only works
correctly if set on the base layer, and if the base layer's
maxExtent's left and right bounds equal the world extent's. With other
words: don't use it for tile caches that only cover a subset of the
world in longitudinal direction.

Andreas.

Hi,

this is because you are using the GMaps v2 API, where the map uses
EPSG:4326 as projection. Please see
http://openlayers.org/dev/examples/google-v3.html for the correct
script resource to include GMaps v3, or configure the layer with the
"sphericalMercator: true" option and the map with

        maxExtent: new OpenLayers.Bounds(
            -128 * 156543.03390625,
            -128 * 156543.03390625,

            128 * 156543.03390625
        ),
        sphericalMercator: true,
        maxResolution: 156543.03390625,
        units: "m",
        projection: "EPSG:900913"

Hi,

OpenLayers.Layer.WFS is deprecated, and what you tried will only work
f you have a proxy configured. My suggestion would be to use
OpenLayers.Layer with a Protocol.Script to get the layer contents. See
http://openlayers.org/dev/examples/cross-origin.html.

I cannot reproduce this in OL 2.11 with the vector-features.html
example. Can you try with latest OL from github, and if the problem
persists provide a minimal example that shows the issue?

Thanks,

Hi,

I use this to calculate the number of acres enclosed by a linestring:

ring = new OpenLayers.Geometry.LinearRing(geometry.getVertices());
area = ring.getGeodesicArea(new OpenLayers.Projection("EPSG:900913"));
area = Math.floor(Math.abs(area*0.000247105381));

The calculated area consistently produces results that are 2-3% too 
small. Is this an error in my code or is my data the problem?

Thanks,

Message-ID: <1326652976338-7190368.post@n2.nabble.com>

Hi

Here's code for a button, that adds selected layer from
app.capabilitiesPanel to app.mapPanel.map (instance of OpenLayers.map), but
effect does not seems to work.

/bbar: [{
	text: "Add Layer",
	handler: function() {
	app.capsGrid.getSelectionModel().each(function(record) {
		var capabilitiesLayer = record.clone();
		capabilitiesLayer.getLayer().mergeNewParams({
			format: "image/png",
			transparent: true,
			transitionEffect = "resize"
		});
		app.mapPanel.layers.add(capabilitiesLayer);
		app.mapPanel.map.zoomToExtent(
			OpenLayers.Bounds.fromArray(capabilitiesLayer.get("llbbox"))
		);
	});
	}				
}]/

Any suggestions?
Many thanks.

Regards,
Tom

The above syntax is wrong.

And transitionEffect is not a WMS parameter, it is an option of the layer
instance.

Try: getLayer().transitionEffect = 'resize';

Solved! It's optional, so I did it this... litle bit ugly way.

/bbar: [{
				text: "Pridaj vrstvu",
				handler: function() {
					app.capabilitiesPanel.getSelectionModel().each(function(record) {
						var capabilitiesLayer = record.clone();
						capabilitiesLayer.getLayer().mergeNewParams({
							format: "image/png",
							transparent: true
						});
						app.mapPanel.layers.add(capabilitiesLayer);
						*var mapLayers = [];
						mapLayers = app.mapPanel.map.layers;
						mapLayers[mapLayers.length-1].transitionEffect = 'resize';*
						app.mapPanel.map.zoomToExtent(
							OpenLayers.Bounds.fromArray(capabilitiesLayer.get("llbbox"))
						);
					});
				}				
			}]/

Do you have the same issue if you just use ring.getArea() function?

I tried that first. It was way off. I think by a factor of cos(lat)**2.

Fair enough. I presume you aren't drawing the linestring by hand yes?
and that there are no obvious rounding errors?

I looked up some Mercator formula on Wolfram and I think my equation in 
not the correct one. That being said, the data is lat/lon from a third 
party program that was imported into PostGIS and then served by GeoServer.

Subject: [OpenLayers-Users] Read a wmc without destroy the map
Message-ID: <4F13E16B.9070304@valabre.com>

Hi,

I would like to read a Web Map Context to modify the options of my map : 
ZoomLevel, BoudingBox, layers visibility...
I followed the OpenLayers WMC example.
First I tried:

map = format.read(text, {map: map}); // the merge solution

But it creates new layers and doesn't refresh the map.

So I tried :

map.destroy();
map = format.read(text, {map: mapOptions});


But I have an error in my MapPanel and M. Matt Prior answered me that 
map.destroy() is the worse solution :
"NO! Never destroy the map unless you want it really and truly gone for 
good."

Do you know another solutions to load a WMC or do I have to parse the 
data to extract parameters ?

Thanks in advance

Regards
Arno

Subject: [OpenLayers-Users] Printing options for map w/ styled vector layers?
Message-ID: <1326813632729-7196710.post@n2.nabble.com>

Guys,

If I have a map with a WMS background layer and a several styled Vector
layers, is it possible to print server-side and still maintain all of my
vector stylings?  If so, approximately how much effort is this and is
MapFish the way to go?

I'm trying to decide if it's worth the effort to deal with styled vectors
server-side or just use the browser/javascript print() function and deal
with its issues.  I have read through the archives and read the wiki but I
didn't see much about maintaining styling when printing server-side.

Thanks!!!
Ashley

Hi Ashley

You have to be able to replicate the styled vectors in OpenLayers within your WMS server, and then write some Javascript code to capture the map extent from OpenLayers plus a list of all the layers displayed and then submit a GetMap request to the WMS to generate a composite map.

I use a Python script in my cgi-bin directory that sits between OpenLayers and Mapserver to request the WMS image and embed it in a PDF file.

Regards,

Robert

Subject: [OpenLayers-Users] creating a custom permalink
Message-ID: <8C734EB5-8B4B-482C-8BEC-4DAD7EC699E4@gmail.com>

I am looking for ideas on how to accomplish the following with the permalink control...


I have a map view constructed with the usual turn a couple of three layers on and zoom to a specific location. To this, I want to add a vector polygon constructed on the map which has, in turn, triggered an ajax call to the server and returned with the prescribed features within that polygon and the results of the call have done something in the map.

For example, say I have a div called "results" which displays the records from a "points" layer of the features within a polgyon. So, how would I go about extending the permalink control output to add all this? Eventually I would just want to save all the gobbledegook on the server side and generate a custom URI that can be emailed to other users.

Suggestion?

If you can bear with something browser-side I've made a Chrome extension
that screenshots the current tab, crops out the ol div and draws it in a
canvas for printing.
It's Chrome only and it's not exactly what you asked for but it occurred to
me somebody could use the idea.

It's on github:

Mapfish can print the features in a vector layer out-of-the-box keeping all
the styles.

Thanks this works. but my problem now is, that all the polygons i have drawn
are deleted when i destroy the control and i get an Error with:

so i any ideas how i can solve this?

Hi,

I've implementad a client with maxExtend (-1.53544921875, 37.81, 0.0000,
40.84) using MS4W.

When I work with the result, the layers are showed correctly, but qhen I
try load five layers (for example) the time is increase.

For each layer, over 9 DIV areas are called, so the total request are 9x5 =
30!!

How can I reduce the number of request and reduce the responde time? Thanks

Message-ID: <CAHkO3UDw9zo6A2+ih-zS=jA6jbeSynX3SBVn1v4055sN2PjvZQ@mail.gmail.com>

Hey guys,
  I'm trying to use a stylemap on a GeoJson datasource, and want to change
the color of the symbol based off of a field in the data.

My data looks like:

{
"type" : "GeometryCollection",
"geometries" : [{
"type" : "Point",
"_id" : {
"code" : "123",
"version" : 0
},
"coordinates" : [-86.586502, 34.731189],
"Status" : "W"
}, {
"type" : "Point",
"_id" : {
"code" : "234",
"version" : 0
},
"coordinates" : [-86.57294326, 34.73563314],
"Status" : "W"
}, {
"type" : "Point",
"_id" : {
"code" : "456",
"version" : 0
},
"coordinates" : [-86.45717254, 34.82754903],
"Status" : "A"
}
]
}


and my style stylemap:

        var styleMap = new OpenLayers.StyleMap({
            "default": new OpenLayers.Style({
                fillOpacity: 0.5,
                pointRadius: 5,
                fillColor: "#ee9900"
            })
        });

        var lookup = {
            "S": {fillColor: "red"},
            "A": {fillColor: "green"},
            "X": {fillColor: "blue"}
        };

        styleMap.addUniqueValueRules("default", "Status", lookup);

However, when I apply the addUniqueValueRules, no features are drawn.
 Tracing through the draw cycle,
line 117 of Comparison.js which is getting the value of "Status" from the
context returns undefined.  What do I need to do to get the "Status" into
the correct context?

Thanks,

John

It seems, that your features are only drawn on a temporary layer. 
And deleting the control or deactivating it, deletes also this layer and
causes the error.

it's nothing wrong with your code. But your GeoJSON object describes a
MultiPoint instead of three single points. 
And the properties should not attached to the geometry.
 
Try something like this to create single points: 
 
{
    "type": "FeatureCollection",
    "features": [
        {
            "type": "Feature",
            "properties": {
                "_id" :
                {
                "code" : "123",
                "version" : 0
                },
                "Status" : "W"
            },
            "geometry": {
                "type": "Point",
                "coordinates": [
                    -86.586502,
                     34.731189
                ]
            }
        },
        {
            "type": "Feature",
 
...
 
by the way Status="W" is not declared in your styleMap.

Hey guys, 
  I'm trying to use a stylemap on a GeoJson datasource, and want to change
the color of the symbol based off of a field in the data.

My data looks like:

{

"version" : 0
},
"coordinates" : [-86.45717254, 34.82754903],
"Status" : "A"
}
]
}


and my style stylemap:

        var styleMap = new OpenLayers.StyleMap({
            "default": new OpenLayers.Style({
                fillOpacity: 0.5,

                fillColor: "#ee9900"
            })
        });
        
        var lookup = {
            "S": {fillColor: "red"},
            "A": {fillColor: "green"},
            "X": {fillColor: "blue"}
        };

        styleMap.addUniqueValueRules("default", "Status", lookup);

However, when I apply the addUniqueValueRules, no features are drawn.
Tracing through the draw cycle,
line 117 of Comparison.js which is getting the value of "Status" from the
context returns undefined.  What do I need to do to get the "Status" into
the correct context?

I don't think OpenLayers's GeoJSON format can produce
OpenLayers.Feature.Vector objects from such a JSON doc. To produce features
the GeoJSON format should receive a doc whose root object is of type
FeatureCollection.

For your rules to work "Status" must be a property of the "properties"
object in each "feature" object of the GeoJSON doc.

So make sure you have correctly formed feature objects in your layer. Each
feature object should a "Status" property in its "attributes" object.

Hope this helps.

Arnd and Eric,

  Thanks for the quick help.  I was thinking that it was looking for the
properties off of the vector feature object, and was hoping passing in a
different context would allow me to keep the fields on the same level as
the coordinates.

  The current json document indeed does draw, but not not with the
addUniqueValueRules set.  Perhaps the formatter is creating a vector
feature good enough to draw, but not filter.

  The source is from a C# web service call to a MongoDB collection (table
in mongo parlance).  And performance is impressive, the 3 points was a
sample from the original 1800 points (hence a W status thrown in there),
which draw faster than the OSM basemap.  In fact performance doesn't start
to drop off until 30K points, far more than I expected.

  Converting the source from a GeometryCollection to a FeatureCollection
ins't a problem, but I have to figure out how to create an object from the
MongoDB document that has the properties object inside the feature object.
 Like I said, I was hoping the context would allow me to fake that :-)

Let me see what I can come up with.

Subject: [OpenLayers-Users] Customize Features
Message-ID: <1326915813580-7201367.post@n2.nabble.com>

Hello all 

I'm not sure where I should post this Q
I'm using a WFS protocol on Vector layer to display my vector features (
Cars ) on the map.

Now I need to customize every feature ( car in my case ) depending on its
type (e.g:small ) and direction (e.g: north ).

So, Which way is better to do that ?
I have found this but still am not sure

Message-ID: <1326921342037-7201670.post@n2.nabble.com>

Hello

I've got an annoying problem:
I use OL to display OSM "Mapnik" and when zooming to level 1 and scrolling
to the edge of the map i always get in firebug

"NetworkError: 404 Not Found - http://a.tile.openstreetmap.org/1/1/2.png"
or
"NetworkError: 404 Not Found - http://a.tile.openstreetmap.org/1/0/2.png"

which blocks the traffic because the browser wants to get the png and get
the png and doesnt get it....
Obviously the http address is wrong; in OSM docs i read that the address
template is

	http://[abc].tile.openstreetmap.org/zoom/x/y.png 

I think the address is evaluated wrong in the XYZ class and XYZ wants to get
a map which doesnt exist.
Can somebody give me a hint how to prevent the error?
By the way when looking at the OL examples there are similar errors.
Look at http://openlayers.org/dev/examples/osm.html, zoom to level 0 and
move the map to the upper/lower border.
And by the way now we see why the examples are initialized at level 10 and
not 0... ;-)

Thanks

It seem an issue with the maxExtent of the OSM Layer.

Try 20017508.34 instead 20037508.34 as ymax for the maxExtent, then the
error should go away.


OSMLayer.maxExtent = new
OpenLayers.Bounds(-20037508.34,-20037508.34,20037508.34,20017508.34);
OSMLayer.displayOutsideMaxExtent=false;

The issue was floated elements within my popup - IE was sending mousemove

Hi lists,

I have a simple question... I've got one vector layer, that might be
sometimes loaded by huge amount of data (hundreds/thousands of features).
What is the limit of features? Thank you!

the question might be simple, the answer it is not ;-)

According to my experience, I would say it depends...
... on the browser type, the complexity of the features, memory and 
CPU's of the PC, what you regard as still acceptable responsiveness of 
the application, etc.

If your features are quite simply structured, i.e. with few vertices 
(rectangle-like polygons, straight short lines, etc), then browsers like 
IE 7/8 (v9 should be faster I guess) should be able to handle a few 
100's. Chrome and Firefox maybe a few 1000's. With more features the 
application becomes more and more sluggish and pan actions become sticky.

If your features are complex then this will happen already with fewer 
features. I have not tried, but I would guess loading as vectors e.g. 
the coastline of Norway, digitized with decent details, can make an OL 
application virtually unusable because a single feature could have some 
100000's vertices.

Well explained, Armin.

Short version: it's not the features, but the vertices.

A significant factor there is the parsing of the vertices: GML/XML is 
significantly more "expensive" than JSON. If you're able to control the 
format of the data you're loading, try making a JSON representation of 
the data and including fewer attributes; this means less processing time 
figuring out the data, which may help raise your ceiling.

If you have control over the dataset you're trying to render, you can 
try a "simplify" on the data (this isn't an OpenLayers thing, it means 
fudging your data server-side). This removes vertices and accuracy, in 
exchange for raising the ceiling further. This can get dicey, though: it 
would be wholly unsuitable for surveying applications, but may work fine 
for indicating general areas such as state boundaries at large scales.

Message-ID: <CAGRA++1nBV3P19JcsgkZao9bm1BNdCe6k23+K1dwY9xQZ=zSHA@mail.gmail.com>

Hi,

I have the next code to show a popup when a user clicks over the map:


info = new OpenLayers.Control.WMSGetFeatureInfo({
url : 'http://localhost:9000/cgi-bin/mapserv.exe',
title : ' ',
layers : [ StatesWms ],
queryVisible : true,
vendorParams : {
map : '/ms4w/apps/demo-cv/demoCV.map'
},
eventListeners : {
'getfeatureinfo' : function(event) {
var popup = new
OpenLayers.Popup.FramedCloud("Datos",map.getLonLatFromPixel(event.xy),
null, event.text, null, true);
  popup.autoSize = true;
map.addPopup(popup);
}
}
});

map.addControl(info);
info.activate();

When I click over the map, the popup with the correct information appears
at the web client, but I want that if I click in another point, the first
popup will be closed and the new will be open. Some help?

Thanks

See the exclusive parameter to addPopup:

Subject: [OpenLayers-Users] Preserve map options when zoom in a map
Message-ID: <CAGRA++1ZhuPvisAB0CvMzA0w3BdDC+pj2Vmd1YGhAji5PMEBOg@mail.gmail.com>

Hi!

In my Ext.onReady(function() I have the next options to the map:

var options = {
controls : [new OpenLayers.Control()],
minExtent : new OpenLayers.Bounds(-1, -1, 1, 1),
maxResolution : 0.35,
maxZoomLevel : 10,
maxExtent : new OpenLayers.Bounds(-1.53544921875, 37.81, 0.0000, 40.84),
tileSize : new OpenLayers.Size(400, 550) //Tama?o de las "tiles" que
conforman el mapa
};

map = new OpenLayers.Map('olmap', options);

And the layers have {'buffer':1} property.

But when I use the toolbar OpenLayers.Control.ZoomBox component, the map is
draw with the default options.

How can I preserve the first configuration although I zoom the map? Thanks

Hello

when starting with OL i reflected on the same problem but finally i decided
to display features only when the user zoomed in to a specific level where
the amount of features wasnt too large...
perhaps this could be a "solution" for you, too.
Besides you can use clusters to combine a lot of features.

Hi all,
i'm wondering if there is a possibility (and how) to create a continuos pan 
(as openstreetmap do in all zoom level) to avoid block pan at the end of map 
extention so repeat tiles. Is there a parmeter to set into OpenLayer.Map 
object? at OpenLayer.Layer ?
Thanks.

Do you mean wrapDateLine?

Hi,

You shoud add a feature not a geometry

var vectorLayer = new OpenLayers.Layer.Vector("layer");

//as the funtion says, you get a geometry

var p = new OpenLayers.Bounds(0,0,10,10).transform(
    new OpenLayers.Projection("EPSG:4326"),
    new OpenLayers.Projection("EPSG:900913")
).toGeometry();  

//console.log(p.CLASS_NAME);

var ft = new OpenLayers.Feature.Vector(p);

map.addLayer(vectorLayer);
vectorLayer.addFeatures([ft]);

Thank you very much.

I'm affraid, my data are vast. I mean, data are measured with a maximum
deviation of two meters. My data consists of 50 thematic layers - small town
- so that means there are realy A LOT OF verticies. 

I presume that the most suitable rendering method will be SVG2. WFS layers
are published from GeoServer and GeoMedia WebMap Pro. Performance of virtual
drive are two cores (4 threads), 2GB DDR3 RAM. The question is, what is the
fastest browser (FireFox / Chrome).

Using BBox strategy will be necessarily. I must not force user to zoom to
see features/layers, so do you have any other ideas how to speed it up?

Regards,
Tom

Subject: [OpenLayers-Users] selectable grid control
Message-ID: <B0DA4309-BA33-4B15-A64C-EC686F76FA19@gmail.com>

I have finally managed to mock up a selectable grid control (see http://mumbai.geology.wisc.edu/test/svg_grid.html). The pseudocode is as follows

    // create styleMap
    var myStyles = new OpenLayers.StyleMap...

    // create and add grid_layer
    var grid_layer = new OpenLayers.Layer.Vector("Grid", {styleMap: myStyles});
    map.addLayer(grid_layer);
    
    // create grid cells
    var cells = [];
    for (var r = 0; r < rows; r++) {
        for (var c = 0; c < cols; c++) {
            ...       
        }
    }
    
    // add the cells to the grid_layer
    grid_layer.addFeatures(cells);

    // add and activate highlight and select controls

I have the following questions:

1. Seems like I am unable to make the grid line thinner. I have set strokeWidth: 1, but it looks rather thick. Can I make it thinner?

2. I want the grid to remain the same size whether I zoom in or out. Do I have to destroy the layer and re-make it on every map change, resize, etc.?

3. "double-click to zoom", "press shift and drag to zoom", or "click-hold and drag to pan" are no longer possible because selectControl takes over. Is there a way to accomplish both?

And, the over-arching question

0. Is there a better way to accomplish all this?


Many thanks in advance for your suggestions,

I am trying to remove a layer with

    if (map.getLayerIndex(layer) > 0) {
        map.removeLayer(layer);
    }

but no joy. How can I remove a layer?

A bonus question: if I want to reconstruct a  vector layer on map "zoomend", that is, redraw all the features on it so they are resized accordingly, should I remove the layer (hence, the question above), or simply remove all the features and redraw the features? If the latter, then how?

Many thanks,

I am completely at my wits end. I am trying to check if a vector layer exists, and if it does, I need to either completely remove it or remove all the features from it (whichever is more efficient from the point of speed and memory), and then redraw that layer. Have been trying all sorts of permutations and combinations, but am just not successful.

My latest code attempt is below, and the original attempt is below that from my OP.

    var arr = map.getLayersByName("Vector layer");
    
    if (arr.length) {
        //map.removeLayer(arr[0]);
        layer.removeAllFeatures();
    }
    else {
        layer = new OpenLayers.Layer.Vector("Vector layer", {styleMap: myStyles});
    }

Neither `map.removeLayer(arr[0])` nor `layer.removeAllFeatures()` works.

Would appreciate suggestions.

I am seeing the same thing today with ArcGIS Server v10 SP1 REST services.
I've tried several different labeling options on the server side ('Remove
duplicate labels', 'Place one label per feature', 'Only place label inside
polygon') but OL still displays several labels per polygon feature.  If I
view the same AGS service using the AGS JavaScript API, the labels are
rendered correctly, i.e. one per polygon.

Has anyone else found a workaround for this?

Thanks in advance.

I want to add the permalink control to the map, but I don't want to display it as is out of the box. Or, to be more precise, I want to build my own permalink link so that I can add a few more custom params to the link that the control builds, and then do something with that link, for example, store it in the db, or pop it in a window, etc.

How can I do that?

Here is an example where are add additional parameters:

I think the correct function is

layer.destroyFeatures();

which will empty the vector layer. You should not remove or re-initialize
the layer. It makes sense to remove the layer from the map if you do not
need it further.

When I specified the original poster's 1005.svg as the externalGraphic
along with graphicWidth: 90 and graphicHeight: 90, it rendered
for me no problem at all in ie9.

Strange, even using the op's SVG all I get in IE9 is a missing image frame,
while it works flawlessly in FF and Chrome. It might be a problem with
GWT-Openlayers. Do you know of a public example (showcase maybe) that uses
(GWT-)Openlayers and SVG as externalGraphic and that works for you?

Subject: [OpenLayers-Users] Find out when rendering of vector features
 (using externalGraphic) is completed
Message-ID: <4F19858A.30509@uni-koblenz.de>

Hi all,

I'm trying to implement a heatmap based on olheatmap
(http://olheatmap.sourceforge.net/). First, an intensity circle is drawn
for each feature using a radial gradient image with differnt alpha
values. Afterwards, the alpha values in the layer's canvas are mapped to
the heatmap's color gradient.

The problem is that rendering the features is not finished yet before
the heatmap transformation starts and I could not find any event which
indicates that the rendering is completed.

I registered listeners for all events of the layer but all I get is
'beforefeatureadded', 'featureadded', 'featuresadded' and mouse events.
I don't observe any 'sketchcomplete' or 'loadend' event.

Is there any way to find out when rendering of the features is done?
(Interestingly, if the mouse cursor is not on the map, it seems that a
'mouseout' event is triggered just after the rendering finishes).

Below is the minimal code I use for generating the heatmap.

Thanks for your help,
Olaf

Hi,
i would like to insert in my map a logo image and a label. For the label i 
used:

var test = new OpenLayers.Layer.OSM("Background",

			"http://localhost/${z}/${x}/${y}.png",

			{

Subject: [OpenLayers-Users] Problem to show tiles of maperitive-render-tiles
Message-ID: <4F199D8F.3060008@tappenbeck.net>

hi !

i have render some tiles for the area of europe - names only by 
zoom-level 4->10.

the layer is include by

var newLayer = new OpenLayers.Layer.OSM.Local("NewLayerLocal");
map.addLayer(newLayer);

additional in OpenStreetMap.js

OpenLayers.Layer.OSM.Local = OpenLayers.Class(OpenLayers.Layer.OSM, {

     initialize: function(name, options) {

         var url = [
             
"http://www.tappenbeck.net/osm/ferry2011/tiles/${z}/${x}/${y}.png"
         ];

         options = OpenLayers.Util.extend(
             { numZoomLevels: 19, isBaseLayer: false}, options);
         var newArguments = [name, url, options];
             OpenLayers.Layer.OSM.prototype.initialize.apply
             (this,newArguments);
     },

     CLASS_NAME: "OpenLayers.Layer.OSM.Local"
});



and you can show in 
http://osm.tappenbeck.net/ferry2011/deu/ferry_iframe_debug.php

the problem now is when the zoom-level is 5 and higher the names of the 
north will repeat - but only in the vertical to the north.

did anyone have a idea ??

Thanks, but nope, that does not work. here is my pseudocode triggered "onzoomend"

    var layer, features = [];
    
    function foo() {
        if (features.length > 0) {
            layer.destroyFeatures();
            features.length = 0;
        }
        else {
            layer = new OpenLayers.Layer.Vector("A vector layer");
            map.addLayer(layer);    
        }
        
        // add features and store in array
        for (var i = 0; i < n; i++) {
            var feature = createFeature();
            features.push(feature);    
        }
        
        layer.addFeatures(features);
    }
    
Everytime I zoom in or out, the above is triggered. features[] has n elements all the time showing that it is emptied and refilled, but the layer from previous iteration is still visible on the map. Any other suggestions?

This should not be so difficult but is confounding me. Maybe it needs its own special entry on a wiki or an FAQ.

Have you got <!DOCTYPE html> at the start of your page?  If missing
that could possibly be the reason IE is behaving differently.

Currently there is no clean way to do this, but the following should
work in all browsers except IE < 9 (untested):

layer.events.register("tileloaded", this, function() {
    if (document.getElementsByClassName("olImageLoadError").length) {
        /* your error handling code here */
    }
});

Note that if you only want to change the appearance of a broken tile,
it is enough to add some css for the .olImageLoadError selector.

Andreas.

Subject: [OpenLayers-Users] minScale maxScale doesn't work
Message-ID: <1327173949694-7211677.post@n2.nabble.com>

Hi,
I'm trying to set min and max scale for layer. I used this part of code:

kontiky_layer = new OpenLayers.Layer.GML("GML",
"kontikyVrstva/kontikyFinalGML.gml", {projection: map.displayProjection,
styleMap: styleKontiky},{minScale: 60000, maxScale: 10000})

But unfortunately layer is still visible in all scales. Whole map with code
is here:  http://vrbikdan.xf.cz/kontiky/kontiky.html
http://vrbikdan.xf.cz/kontiky/kontiky.html . Can you tell me what is wrong?

Thanks,
Dan

Subject: [OpenLayers-Users] WMS requests  executed twice
Message-ID: <4F1B1FA2.5060002@uva.nl>

Hi all,

I made a very simple OpenLayers test site, displaying a simple local 
MapServer map as an untiled WMS service. Works fine, but when I look in 
the server log, each OpenLayer GetMap request results in *two* identical 
requests to the server. Can anyone confirm this, and why does it happen?

Have you made sure you've only got a bounding box OR a fixed strategy on
your wms layer? That has caught me out once or twice. If not, post some
code.

Great help, thanks. That got me started, but I don't have a working solution yet. Here is what is going on... I am trying to customize the permalink control using the following function

    var state = {};
    
    new OpenLayers.Control.Permalink(
        "permalink", 
        uri, 
        {
            "createParams": function() {
                var args = OpenLayers.Control.Permalink.prototype.createParams.apply(
                    this, arguments
                );
    
                // add my args here
                if (state) {
                    for (var s in state) {
                        args[s] = encodeURI(state[s]);
                    }
                }
                
                return args;
            }
        }
    );
            
and then, in my map I have buttons that invoke different functionality. For example, one functionality is like so
    
    "doThat": function(a, b, c) {
    
        // update state
        state = {
            action: "doFoo",
            params: {
                a: a,
                b: b,
                c: c
            }
        };
        
        .. do something ..
    };
    
My intent is to generate a permalink that looks like so

    http://server/app?zoom=6&lat=-1.35&lon=-38.14&layers=TB000TTTTT&action=doThat&a="foo"&b=43&c="bar"
    
The problem is, by the time doThat() is called and it updates state, the permalink has already been formed, so it doesn't yet have the updated values from "state". If I now move the map or do something else, that is when the permalink gets updated with the values from "state" but it is always one action behind ? how do I get around this phase lag? In other words, I want to update the permalink *after* the "state" has been updated so that when "createParams" is called, it creates the correct permalink.

anyone, any suggestions? I am stuck on this for a couple of three days now. Briefly, I want to remove all the features from a vector layer so I can draw them anew on every "zoomend"

Many thanks in advance.

Subject: [OpenLayers-Users] simple text or html control
Message-ID: <CACEnT=eRKCSgs3agb96TX7JeKDOQm546z0LQD5JRiaEibfZ_PA@mail.gmail.com>

I'm converting a fairly complex GoogleMaps V3 app to use OpenLayers.
So far, so good - seems to work well.

I've been looking through the documentation / examples for a way to add a
control within the map div where the control contains either simple text or
else it contains html (tables, forms, etc).  The control would be
positionally fixed on the screen, not tied to a geo position

So far I haven't found an example of a way to do this.  It's probably
staring me in the face but...

Can someone point me at the solution?

Thanks

one additional note: I don't want the actual link that the user would click to get the permalink to have the updated link. Instead, I want to actually fire off a function to do something with that link. Right now I am using something like so, which actually does work. Just want to confirm if there is a better way

	<a href="" id="permalink">permalink</a>

	$("#permalink").click(function() {
		doSomethingWithPermalink($(this).attr("href"));
	   	return false;
	});

For example, I might want to replace the href with '<div id="permalink"></div>'. In which case, how would I get the current value of permalink?

Hi,  whenever I want to display a Vector Layer in a scale range I always
add Rules to my mapStyle.
I modify your code to achive this.


var defaultStyle = new OpenLayers.Style();

var template = {'pointRadius': 10,
'externalGraphic': 'png/symboly/plastAlpha.png'
};

var rule = new OpenLayers.Rule();
rule["minScaleDenominator"] = 60000;
rule["maxScaleDenominator"] = 10000;
rule["symbolizer"] = template;
defaultStyle.addRules([ rule ]);

var styleKontiky = new OpenLayers.StyleMap({'default': defaultStyle,
'select': selectStyle});

Hope it's usefull.
Regards
Nacho

Ignore my answer. That would only apply to vector layers.

There was <!DOCTYPE HTML PUBLIC &quot;-//W3C//DTD HTML 4.01

Does anybody have an idea how to solve this problem?
It is been braking my head for a couple of days already.

Cheers,

Subject: [OpenLayers-Users] Performance issues (memory leak?) with WFS
Message-ID: <D7383CD4D59FEA4DA879EF5096A5A8CB15993CE0CE@exvic-mbx03.nexus.csiro.au>

Hi all,
I'm building a web application to display data that is updated in real-time (ship's navigation/sensor underway data). I'm using WFS (served up by a Geoserver/PostGIS backend). The core of it looks like this:

underwayWfsProtocol = new OpenLayers.Protocol.WFS.v1_1_0({
    url:  "http://ss-geospatial-hf:8080/geoserver/visage/wfs",
    featureType: currentVoyage,
    featureNS: "visage",
    geometryName: "position"});
        
underwayLayer = new OpenLayers.Layer.Vector("Underway Data", {
    strategies: [new OpenLayers.Strategy.BBOX(), new OpenLayers.Strategy.Cluster({distance: 10}), new OpenLayers.Strategy.Refresh({interval: 300000, force: true})], //Refresh screen every 60 seconds, cluster points //TODO - performance issues
    protocol: underwayWfsProtocol,
    styleMap: new OpenLayers.StyleMap({ //TODO - dynamic styling based on zoom level etc, make latest point different
    pointRadius: 3,
    fillColor: "#ff0000" })});

map = new OpenLayers.Map({
    div: "map",
    layers: [baseLayer = new OpenLayers.Layer.WMS(
        "Bathymetry",
        "http://ss-geospatial-hf:8080/geoserver/visage/wms",
        {layers: "visage:bathytopo2005tif"})],
        center: baseLayerBounds.getCenterLonLat(),
        zoom: 4});
    
map.addLayer(underwayLayer);

I also have some other standard bits and pieces, like a graticule, popups on feature select and so on. Nothing too unusual. 

My problem is with performance - my development platform is Firefox 9.0.1, Win7 64. The map and features load fine initially, however after a number of updates (via the refresh strategy) Firefox's memory usage will balloon, crashing Firefox (and sometimes my whole system) in fairly short order. I've tried with both OpenLayers 2.11 and the latest trunk version.

Any advice would be great - I'm at a bit of a loss. If at all possible I'd like to stick with the WFS approach, as the functionality is a good fit for my application vs WMS - just not the performance.

Cheers,

Hugh Barker

Rendering the points isn't the issue. I'm happy with the performance, especially using clustering.

The issue is with the refresh strategy, which causes memory issues (it looks like a memory leak) across subsequent updates. Memory usage increases roughly linearly with each update, until the browser crashes.

You simply can't render large amounts of vector data in a browser, Firefox and Chrome can handle a lot more vector data than IE, but you will always have problems

ah, ok...

do you see the same leak issue with firebug completely disabled?

That did the trick, thanks!
There was <!DOCTYPE HTML PUBLIC &quot;-//W3C//DTD HTML 4.01
Transitional//EN&quot;> in the GWT-Openlayers showcase startpage which does
not work. Omitting the doctype does not work either.
<!DOCTYPE html PUBLIC &quot;-//W3C//DTD HTML 4.01 Transitional//EN&quot;
&quot;http://www.w3.org/TR/html4/strict.dtd&quot;> and <!DOCTYPE html PUBLIC
&quot;-//W3C//DTD HTML 4.01//EN&quot;
&quot;http://www.w3.org/TR/html4/strict.dtd&quot;> for example work as well.
As far as I can judge it, it seems like it does not work in Quirks mode in

Hmm, that seems to have fixed the issue - memory stays at a reasonable level.

I should have thought of disabling it before - I knew there was a memory overhead associated with Firebug, but I kind of assumed it would just be a constant overhead - instead it almost looked as if Firebug was preventing garbage collection or something. Oh well, you live and you learn. Thanks for your help.

What if you set minScale and maxScale in the same object as where
projection and styleMap are set?

Note: Layer.GML is deprecated, you should use a Vector layet configured
with a Fixed strategy and an HTTP protocol. Look at the OpenLayers example.

Subject: [OpenLayers-Users] Find out when rendering of vector features

Hi,

the problem is that you're using an external graphic, which is added
to the canvas in an onload handler. So try to render your circle just
with pointRadius, fillColor, strokeWidth and strokeColor, and not
externalGraphic and offsets, and you'll be fine.

Andreas.

Subject: [OpenLayers-Users] Styling polygons with an externalGraphic
Message-ID: <CAJmUSVgccOqEuuooz=7TiDktD8CArqzd6fDJvQnxMXXWNhM8nw@mail.gmail.com>

Hi all,

I have a vector layer containing polygon features that I'm quite
happily styling with coloured outlines and fills.

However, I would like to display an externalGraphic instead of the
normal fill/outline.
http://osgeo-org.1803224.n2.nabble.com/Show-polygon-vectors-as-points-td1829267.html
hints that it's possible, but I can't get it working. Are there any
examples out there of polygons symbolized with externalGraphics?

Thanks in advance for any pointers, or even if it's not possible, some
confirmation on that!

Cheers,
Andy

Message-ID: <1327342157541-4333123.post@n6.nabble.com>

We are using snap to edge for feature editing. But when using this, features
do not snap precisely. After committing (through Geoserver), the resulting
vertex falls about 1-3 meters from the real edge which violates our topology
rules. What could this be connected with? Can this be related to current
zoom level (although we didn't see a correlation)?

In-Reply-To: <1327156900220-7211128.post@n2.nabble.com>

Message-ID: <4F1EC0620200003700011E17@gate1.asurequality.com>

I am using OpenLayers v2.11, and have a vector layer loaded from  geometry in WKT format separated from attributes using pipe delimited text from a database (via a Python cgi-bin script).

I am trying to write a function that iterates through all of the features and then POST updates back to the database when certain conditions are met.
 My difficulty is that layer.features.length is returning double the number of features.

Here is my code that creates the layer and loads the features:

function setHTML4cr(response4) {
	var cropnum = 0;
    var lines, line;
    var cropid, name, crds;
    var cropgeom;
    if (response4.responseText.toUpperCase().indexOf('ERROR') != -1) {
      alert(response4.responseText);
    }
    else {
      crops = new OpenLayers.Layer.Vector("Crops",
                  {isBaseLayer: false,
                   styleMap: crop_style,
                   rendererOptions: {zIndexing: true},
                   extractAttributes: true });
      var lines = response4.responseText.split('\n');
      for ( var i=0;i<lines.length;i++) {
        line = lines[i].split("|");
        if ( line.length == 3 ) {
          cropid = line[0];
          name = line[1];
          crds = line[2];
          cropgeom = wkt_format.read(crds);
          cropgeom.attributes.id = cropid;
          cropgeom.attributes.name = name;
          cropgeom.attributes.pstate = "pre";
          crops.addFeatures(cropgeom);
		cropnum = cropnum + 1;
        }
      }
      map.addLayer(crops);
      alert("Crops layer loaded and ready for digitising with " + cropnum + " features!");
}

This is reporting the correct number of features, and the features are drawn on the map.

However, this function is reporting double the number of features:

function savecrop() {
	var f;
    alert(crops.features.length);
	 var allf = [];
    for (i = 0; i < crops.features.length; i++) {
	f = crops.features[i];
	allf.push(f.attributes.id + "|" + f.attributes.name + "|" + f.attributes.pstate + "|" + f.state);
    }
    alert(allf.join("\n"));
}

Many thanks,

Robert

Message-ID: <4F1EE5BE0200003700011E1D@gate1.asurequality.com>

THis appears to be due to a synchronisation issue between OpenLayers and a Ext.grid.GridPanel loaded with a GeoExt.data.FeatureStore tied to the vector layer. I am looking for a way to force an update to the GridPanel when an attribute was modified, and was using:

cropStore.unbind(); 
cropStore.bind(crops); 

but this seems to be causing the features to b re-added to the layer, resulting in a doubling.

Can anyone suggest how to get GeoExt to re-read the features so the GridPanel is updated with the new attributes?

Many thanks,

Robert

                   styleMap: crop_style,
                   rendererOptions: {zIndexing: true},
                   extractAttributes: true });
      var lines = response4.responseText.split('\n');
      for ( var i=0;i<lines.length;i++) {
        line = lines[i].split("|");
        if ( line.length == 3 ) {
          cropid = line[0];
          name = line[1];
          crds = line[2];
          cropgeom = wkt_format.read(crds);
          cropgeom.attributes.id = cropid;
          cropgeom.attributes.name = name;
          cropgeom.attributes.pstate = "pre";
          crops.addFeatures(cropgeom);
		cropnum = cropnum + 1;
        }
      }
      map.addLayer(crops);
      alert("Crops layer loaded and ready for digitising with " + cropnum + " features!");
}

This is reporting the correct number of features, and the features are drawn on the map.

However, this function is reporting double the number of features:

function savecrop() {
	var f;
    alert(crops.features.length);
	 var allf = [];
    for (i = 0; i < crops.features.length; i++) {
	f = crops.features[i];
	allf.push(f.attributes.id + "|" + f.attributes.name + "|" + f.attributes.pstate + "|" + f.state);
    }
    alert(allf.join("\n"));
}

Many thanks,

Robert

Michal,

 

It looks like there are problems in Opera too.

 

Anyway, try playing with the debugging console of IE9. It reports some
errors on init:

 

SCRIPT5007: Unable to get value of the property 'notrack': object is null or
undefined 
portal.js, line 57 character 198

 

SCRIPT5009: 'Math' is undefined 
www-embed_core_module-vflv9x8EB.js, line 4 character 263

 

SCRIPT5009: 'yt' is undefined 
8eoKYGknXxo, line 33 character 5

Hi Guys!

 

I have serious problem with my app on IE (I am not the only one I suppose:)

http://www.webgis.24gis.pl/coi_kielce/index.php

 

On FF nad Chrome it works fine but on IE, map and conrols do not want to
show at all...

I ask you for spending couple of minutes to examine a code or indicate a
place where is an error...

 

Thanks a lot!

Michal

Hi everybody,

is there a way to use the map.raiseLayer function for the visible layers 
only?

If i use it like this: "map.raiseLayer(activeLayer, 1);" i have to click 
once for every layer in the webgis, and not only once for every visible 
layer.

Kind regards

Message-ID: <4F1EB29F.4020401@terrestris.de>

Hi list,

I currently fail at implementing the following:

Build a map that has a OpenLayers.Layer.OSM-layer, but which will only 
display some of the possible zoomlevels, e.g. only the zoomlevel 11 
(resolution = 76.43702827148438) and the zoomlevel 13 (resolution = 
19.109257067871095).

This sounds easy at first... but yet I am struggling with this. I tried 
numerous combinations of resolutions, serverResolutions and zoomOffset 
but without success. Is this doable with current 2.11-API?

Thanks for any help on this.

Best regards,
Marc

Hi,

This is because OpenLayers requests tiles, and the server doesn't know
about neighboring tiles. An easy fix would be to request the content
in a single image. To do so, configure your layer with the

singleTile: true

option.

Andreas.

Hello, 

I've got .map in my html and that's got width and height. 
The map shows up fine, but throws these errors: 


Unexpected value NaN parsing width attribute.
Unexpected value NaN parsing height attribute.
Unexpected value 0 0 NaN NaN parsing viewBox attribute.


I had a look at the code in Firebug and looks like this line is causing
these errors

<svg id="OpenLayers.Layer.Vector_27_svgRoot" width="NaN" height="NaN"
viewBox="0 0 NaN NaN"/>

Does anyone know why it's happening?

Thanks

Hi Andreas,

helpfull as always! This is indeed a very cool addition to OpenLayers. I 
will see if the application in question can move to git-master.

Thanks a lot and kind regards,

Message-ID: <4F1FE4030200003700011E27@gate1.asurequality.com>

Solved this, with the help of Andreas Hocevar:

In my definition of the FeatureStore, I removed autoLoad:true

cropStore = new GeoExt.data.FeatureStore({
        layer: crops,
        fields: [
            {name: 'id', type: 'int'},
            {name: 'name', type: 'float'}
        ]
      }); 

To refresh the GridPanel after modifications of feature attributes I call:

cropStore.loadData(crops.features, false);

Regards,

Robert

>>> Robert Sanson 24/01/2012 5:09 p.m. >>>
THis appears to be due to a synchronisation issue between OpenLayers and a Ext.grid.GridPanel loaded with a GeoExt.data.FeatureStore tied to the vector layer. I am looking for a way to force an update to the GridPanel when an attribute was modified, and was using:

cropStore.unbind(); 
cropStore.bind(crops); 

but this seems to be causing the features to b re-added to the layer, resulting in a doubling.

Can anyone suggest how to get GeoExt to re-read the features so the GridPanel is updated with the new attributes?

Many thanks,

Robert 

>>> Robert Sanson 24/01/2012 2:29 p.m. >>>
I am using OpenLayers v2.11, and have a vector layer loaded from  geometry in WKT format separated from attributes using pipe delimited text from a database (via a Python cgi-bin script).

I am trying to write a function that iterates through all of the features and then POST updates back to the database when certain conditions are met.
 My difficulty is that layer.features.length is returning double the number of features.

Here is my code that creates the layer and loads the features:

function setHTML4cr(response4) {
	var cropnum = 0;
    var lines, line;
    var cropid, name, crds;
    var cropgeom;
    if (response4.responseText.toUpperCase().indexOf('ERROR') != -1) {
      alert(response4.responseText);
    }
    else {
      crops = new OpenLayers.Layer.Vector("Crops",
                  {isBaseLayer: false,
                   styleMap: crop_style,
                   rendererOptions: {zIndexing: true},
                   extractAttributes: true });
      var lines = response4.responseText.split('\n');
      for ( var i=0;i<lines.length;i++) {
        line = lines[i].split("|");
        if ( line.length == 3 ) {
          cropid = line[0];
          name = line[1];
          crds = line[2];
          cropgeom = wkt_format.read(crds);
          cropgeom.attributes.id = cropid;
          cropgeom.attributes.name = name;
          cropgeom.attributes.pstate = "pre";
          crops.addFeatures(cropgeom);
		cropnum = cropnum + 1;
        }
      }
      map.addLayer(crops);
      alert("Crops layer loaded and ready for digitising with " + cropnum + " features!");
}

This is reporting the correct number of features, and the features are drawn on the map.

However, this function is reporting double the number of features:

function savecrop() {
	var f;
    alert(crops.features.length);

Subject: [OpenLayers-Users] Vector layer not drawn when panned with the mouse
Message-ID: <CA+FC_hw-82+9-PrqSzXXDGkZhwQE2FDHqwy8Dua6_adt1bEYyA@mail.gmail.com>

Good day,

I'm using a KML overlay, and am having an odd problem: When you pan the map
with the mouse, the vector layer is not drawn on the newly visible areas.
If you zoom in or out it will appear. Also, if you pan with the panzoombar
it will display correctly.

As a possible workaround, I added an event:

map.events.on({moveend: function(evt) { alert("Hey"); return true;
trackLogKMLLayer.redraw();} });

The alert & return false I added after to see if it was being triggered.
The interesting thing I found was that this event is not being triggered
when I pan with the mouse, but is when I use the panzoombar.

The layer is being added as follows:

	function activateUploadedTrackLog(f)
	{
		var n = document.getElementById('gpsTrackName').value;
		document.getElementById('gpsTrackName').value = '';
		document.getElementById('gpsTrackFile').value = '';
		trackLogKMLLayer= new OpenLayers.Layer.Vector(n, {
			projection: map.displayProjection,
			strategies: [new OpenLayers.Strategy.Fixed()],
			protocol: new OpenLayers.Protocol.HTTP({
			    url: f,
			    format: new OpenLayers.Format.KML({
				extractStyles: true,
				extractAttributes: true
			    })
			})
		    });

		 map.addLayer(trackLogKMLLayer);

Thoughts?

Thanks

Paul

Hi Shadin,

Have a look at 
http://openlayers-buch.de/beispiele/chapter-10/layer-lineDirection.html 
(which is working on an older version of OpenLayers), which might be of 
help. This is the source code: 
http://openlayers-buch.de/beispiele/chapter-10/OpenLayers.Layer.LineDirections.js.

Best regards,
Marc

Hi Shadin,

Interesting timing - I just finally got on this list, and this is the first
message I received, and I just was working on just that in my project.....

Here's what I've done:

In my PHP code I'm creating a KML file that I'll be loading, and I do the
following:

                                ## Divide the bearing by 22 to get a value
from 0-15 for icons
                                $p->setStyleUrl('#track-' .
round($this->bearing[$c] / 22));

This sets the style in my KML to reference "track-4.png" (or any other
number from 0-15)

In my style declarations in the KML I have:

<Style id="track-0">
<IconStyle>
<hotSpot x="19" y="0" xunits="pixels" yunits="pixels" />
<color>8800aa00</color>
<colorMode>normal</colorMode>
<scale>1</scale>
<Icon>
<href>img/KMLIcons/track-0.png</href>
</Icon>
</IconStyle>
</Style>
<Style id="track-1">
<IconStyle>
<hotSpot x="19" y="0" xunits="pixels" yunits="pixels" />
<color>8800aa00</color>
<colorMode>normal</colorMode>
<scale>1</scale>
<Icon>
<href>img/KMLIcons/track-1.png</href>
</Icon>
</IconStyle>
</Style>

Also there is "track-none.png" for a non-directional marker.

I just remembered that the hotspot is wrong there - change it so x and y
are 0.5, and use "fraction" for the units to have it align over the centre
of the location.

If you want the icons, there's a zip file with them at
http://vint.ca/dumps/directionalKMLIcons.zip

Cheers

Paul

Subject: [OpenLayers-Users] Find out when rendering of vector features

Hi Andreas,

thanks for the hint and the advice. I'm quite new to javascript and
openlayers. So there are some (internal) things I don't understand yet.

Finally, I found a solution (in another heatmap implementation) which
draws radial gradients directly on the canvas. This works much better
than the olheatmap approach using external graphics.


var rad = 1000 / (1.1 * Math.pow(2, 16 - map.getZoom()));
var ctx = heatmapLayer.renderer.canvas.canvas.getContext('2d');
var grd = ctx.createRadialGradient(rad, rad, 0, rad, rad, rad);
grd.addColorStop(0.0, 'rgba(0, 0, 0, 0.5)');
grd.addColorStop(1.0, 'transparent');

for (i=0; i<200; i++) {
	var point = new OpenLayers.LonLat(1270000+Math.random()*30000,
6120000+Math.random()*24000);
	var pos = map.getLayerPxFromLonLat(point);

	ctx.fillStyle = grd;  // must be set anew in every loop
	ctx.translate(pos.x - rad, pos.y - rad);
	ctx.fillRect(0, 0, rad << 1, rad << 1);
	ctx.translate(rad - pos.x, rad - pos.y);
}


Cheers,
Olaf

Hi,

Has anyone successfully used MBTiles to server basemaps in Openlayers?
Do any live example exist if yes?

Hi,

I have a map which returns some data in a PopUp when the user clisk over
it. The problem is that when the click is in one area outside the map, I
obtain the next error:

Uncaught TypeError: Cannot read property 'w' of null


var mapSize = this.map.getSize(); in "Popup.js" at the API returns

Hi Robert,

You can do this through the OpenLayers.Layer.XYZ() class with some
code server side to mimic a standard XYZ grid.
I've done this within the mapshup framework (http://mapshup.info).

Server side, you need to create a script that converts XYZ requests to
mbtiles requests.
See http://code.google.com/p/mapshup/source/browse/server/utilities/mbtsrv.php
for an example of this script.

Suppose that you access this script on http://localhost/mbtsrv.php,
you should set your layer like this client side :

var newLayer = new OpenLayers.Layer.XYZ("mbtile",
'http://localhost/mptsrv.php', {isBaseLayer:true});

Regards

Jerome

You need server-side software to open the MBTiles file and fetch the 
tiles. TileStache and TileStream are two popular servers for doing this.

TileStache is Python and I found it fairly easy to set up. It runs under 
Apache as CGI, mod_python, or WSGI. If you have an existing web server 
and web content, this is probably the easiest way to go.

TileStream is written in Node JS and takes a bit more setup. It does not 
run under Apache, but is its own server with its own service port and it 
has some behaviors regarding the hostname of incoming requests -- 
running it on port 80 with your other web content is not simple.

Thanks for the reply,

So TileStache?can serve and render the MBTiles to use with openlayers? Would you know if there are possibilities for exporting mapcontent from the openlayers mappanel?


This is one of the reasons i?m looking in this directory as I can?t do pdf exports with geowebcache served from geoserver.

Thanks,

Rob

I suspect you might have the same problem. We have solved this by
calling the appropriate WMS layer from the geoserver to do the print
request. The problem with any tiled base approach is that either you
have to cut down the tile parts that run outside of your export area,
or you have to go to the closest tile, which at lower resolutions is
quite a big geographical distance.

Correct. http://tilestache.org/doc/TileStache.MBTiles.html

It can serve up an existing MBTiles file. But according to the docs, it 
will not save tiles to a MBTiles file -- you need an existing MBTiles 
file, or can use tilestache-seed to create one.

This seems independent of your MBTiles question. TileStache and other 
map servers probably won't get involved with loading the content of your 
map and then creating a PDF.

Check out some of the resources here:
    http://trac.osgeo.org/openlayers/wiki/Printing

Our current favorite method is wkhtmltopdf. You basically write a new 
page using JavaScript and OpenLayers as usual, have it set the map's 
zoom and center and basemap -- so that when the page opens it's showing 
exactly the map you want. Dump the HTML to a file, have wkhtmltopdf 
convert the HTML file to a PDF (yes, wkhtmltopdf speaks JavaScript, even 
jQuery, Bing Maps, and OpenLayers). Really slick.

Thanks Tobias.

I remember your forum post from November last year...


"...So to get this working, you might be able add quite a simple loop.In your printprovider.js in line 367 there is a loop to populate the
json object with the layers that you are wanting to get printed.
So onto line 369 add:
if (layer.url == "http://maps.zgb.de/geoserver/gwc/service/wms"){
layer.url = "http://maps.zgb.de/geoserver/zgb/wms")
else
{}

(untested code, probably missing ;'s and other stuff!)...

Toby.

..."

This never did work for me....and I decided to enjoy christmas and start the whole thing again in 2012. Unfortunately we are already in 2012 and the niggly little jobs which I need to solve have appeared again!

If you have time to help me crack this one I?d be much appreciated. ?ps..i?m located in D-31822.

yours,

Rob

Wow, what a cool tool!   Am I correct in my (brief) reading of the license
that it is more permissive than GPL?

http://www.cecill.info/licences/Licence_CeCILL-B_V1-en.html

I have a client that needs a map to integrate with some of our tools,
although I'm guessing that I'd be able to do this without actually
modifying the mashup code, simply configuring the widgets and search, etc.

The license mentions "External Modules".  Is their documentation or a
mailing list for developing those?

Thanks, and thanks again for a great tool, is it on the OpenLayers example
page somewhere? (http://openlayers.org/dev/examples/)  It's a great site
for showcasing OpenLayers' capabilities.

Subject: [OpenLayers-Users] Tile stitching with a server-side program
Message-ID: <1327565360.55752.YahooMailNeo@web24104.mail.ird.yahoo.com>

Hi,

I am trying to sort out a satisfactory printing mechanism for slippy maps in openlayers.

My set up is Ubuntu 10.04 / Tomcat6 / Geoserver2.1.2 / Openlayers / GeoExt

My Baselayers are either TMS WTMS or GeoWebCache.....these cannot be printed with the mapfish print module ( only wms)

So...I am looking at the "Tile stitching using a server-side program" - script found here

http://trac.osgeo.org/openlayers/wiki/Printing?


Has anyone managed to get working? ? I am having a problem understand the Javascript..

My alert below is always empty...I tried putting in the name of the layer, but this also returns null!

for (layername in map.layers) {
? ? ? ? // if the layer isn't visible at this range, or is turned off, skip it
? ? ? ? var layer = map.layers[layername];
alert(layer);
? ? ? ? if (!layer.getVisibility()) continue;
? ? ? ? if (!layer.calculateInRange()) continue;



If anyone has done something similar, please report!

yours,

Rob

I really appreciate that you like this application :)
Yes the license is more permissive than GPL. It can be compared to the
BSD license : you can do what you want with the code without giving
back the modifications to the community. The main difference with BSD
is that you need to expressively mention mapshup in your software -
let the mapshup logo within the map for example.

It's a very generic licence so "External Modules" do not refer
specifically to mapshup. However the application architecture is based
on a "plugin" approach to allow people to develop their own
functionality. Unfortunately i had no time yet to write documentation
so for the moment you need to look at the code to understand how it
works.
To have some idea about what you can by configuration, you should look
at the default configuration file
(http://code.google.com/p/mapshup/source/browse/client/js/mapshup/config/default.js).

I'm preparing some minimal documentation to explain how the tool works
and how you can configure/modify it to suits your needs.
For example, there are some hidden functionalities that are not
visible at first sight :
 - you should try to drag&drop an url on the map (WMS, WFS, GeoRSS) or
a file (GeoJSON, JPEG with GPS information stored in EXIF, etc.)
 - when you click for more than 200ms on the map, a popup menu appears

I think that the examples page is dedicated to OpenLayers examples
only and not to "OpenLayers based application".
But i'll be pleased to showcase OpenLayers capabilities through mapshup !

Hi Andreas

I was just going to send a follow up post. 
It's been fixed. 

This is a bit of insights..

Background: 
We have two tabs, fist one shows up a static map image, another shows
the OL map. 

To achieve these tab navigations, we needed to add "display:none" by
javascript to hide one of the containers.

Issue:
As the second tab contained OL map and the tab container defaults to
display:none when loading, width and height assigned to map div was
getting removed and throwing an error.

So we did:
Create a function to makeMap then only triggers it when the second tab
was clicked. 

Thanks as always for your support. 

takako

Subject: [OpenLayers-Users] mousewheel jumps two zoom levels
Message-ID: <784FAC631C0CB14CAE68764151D5DA410B68E195@CORRIOL.icc.local>

Hi list,

 

I've an OpenLayers.control.Navigation with following config options:

 

        var navControl = new OpenLayers.Control.Navigation({

            type: OpenLayers.Control.TYPE_TOGGLE,

            zoomWheelEnabled: true,

            mouseWheelOptions: {interval: 1}

        });

 

But when user changes map zoom level using mousewheel, map zoomlevel jumps from 0 to 2 and then to 4, etc.

 

Is possible to change this behaviour and force change zoomlevel one by one ?

 

Thanks in advance.

Hi Jeff,

Nice posts. Very clear !
One remark : in the "Introduction to OpenLayers" post you mention the
EPSG:3785 srs. I think it is deprecated an replaced by EPSG:3857 srs
(see http://wiki.openstreetmap.org/wiki/EPSG:3857)

Regards

Jerome

Subject: [OpenLayers-Users] Catching WMS errors when using
	OpenLayers.Layer.WMS... can it be done?
Message-ID: <CABmnCf4PBfjpKqoHn5Kp5XJVLkHeaWE7TQfsimX6idkDZb_Yzw@mail.gmail.com>

Hi!

I am working with OpenLayers 2.10 and I have a question regarding error
trapping when using OpenLayers.Layer.WMS (or OpenLayers.Layer.WMS.Post). My
goal is to provide some validation that a WMS layer has been configured
properly and that the custom SLD being dynamically applied is also valid.
I'm open to suggestions as to how to accomplish this, however to date my
efforts have involved setting the EXCEPTIONS parameter in the WMS params to
return application/vnd.ogc.se_xml and then attempting to intercept the WMS
response in order to check. In a success situation the WMS will return a
.gif image. If there's an error the WMS will send the little snippet of XML.

I have included a functional WMS link below that has a deliberate error
with the SLD reference given. I have also included the XML response.

My issue is that I cannot for the life of me figure out how to get my hands
(programmatically speaking of course) on that XML error response when the
tiles are loaded by the OpenLayers.Layer.WMS object. I would like to
intercept the response to the call made by the OpenLayers.Layer.WMS class
to the WMS server when loading the tiles. It appears as if the events
provided that would be of possible use in my case are limited to 'loadend'.
With a little trickery I was able to get a 'tileloaded' event listener to
fire, however both listeners only promote the OpenLayers.Layer.WMS instance
to the listener function and do not give access to the request/response
made to/from the WMS server.

Any thoughts?

Thanks in advance for your help!
Paul


The pertinent params:
SLD=http://somethingbogus
EXCEPTIONS=application/vnd.ogc.se_xml

My guess is that you have two Navigation controls. One that is added
to the map by default unless you configure it with your custom array
of controls, and the navControl you added.

You can check in the javascript console by trying

map.getControlsByClass("OpenLayers.Control.Navigation");

and see if it returns an array of length 1 or 2.

The obvious fix is to configure the map with your own default set of controls.

I'm facing a similar problem, but for my app its a cross-browser issue 
on windows machines only! on linux its fine and the map has only one 
Navigation Control.

does this help to spot the problem?

Hi,

whether one tick on the mouse wheel is one zoom level or not depends
on the mouse sensitivity, which is a system-wide setting. You can,
however, pass something like

mouseWheelOptions: {interval: 20, cumulative: false}

to the Navigation control, and it will only change the zoom by 1 for a
20ms drag. You can try this setting online here:
http://openlayers.org/dev/examples/mobile-wmts-vienna.html

Message-ID: <CANb4N3kD=nOCOggJK7piVTHfzENvz_5HOQnp88ARBcmDgxP-1w@mail.gmail.com>

Hello list,

I've been trying to get a WMS layer that I'm serving from geoserver to show
up over bing as a basemap. My layer appears at the first zoom level
but disappears when I zoom in. I'm playing with the minResolution and
maxResolution and the scales figuring that it needs to match the base
layer. Any advice on how to get up to speed on the relevant bits to make
this work?

Thanks,

Kjel

Subject: [OpenLayers-Users] How to test if a point is within WMS layer?
Message-ID: <1327602659260-4341265.post@n6.nabble.com>

I have a multipolygon layer in GeoServer that I can show as a WMS in
OpenLayers. I want to geocode a location and place a marker on the map (got
this working) and determine if that marker is inside or outside the
multipolygon layer. 

I thought I could use WFS to get all the features of the polygon layer then
use OpenLayers.Format.GML.parseGeometry.multipolygon to turn it into a
polygon object in OL. Then I could use
OpenLayers.Geometry.Polygon.containsPoint to test if the point is within the
polygon. First Question: is this logic sound?

The next issue is that I can't get the WFS for this layer to work. It hangs
my GeoServer when I request it. I guess the layer is too big? Does anyone
know how I could use OpenLayers to display the layer as a WMS but query on
the back end (GeoServer) if my 'point' is within the layer?
Thanks, 
Matt

Is your bing layer imagery? I've had nothing but issues combining layers with
Bing Imagery layers.
Anyhow, can you post the relevant code so we could take a look?

Looking at it now I see the version that is working "best" is with the wms

Yes, it is sound and also easy to implement. But you may have an issue 
if it's more than a few thousand vertices. You may hang the browser 
simply parsing the GML.

The server-side method you are already attempting, sounds like your best 
bet. I'm sorry I have no help for you on the hanging problem.

Hi,

you only need the bounding box of the layer, which you can get from
the WMS GetCapabilities response. Use
OpenLayers.Format.WMSCapabilities to parse it, and look for the llbbox
or bbox properties inside the layer object.

Andreas.

Hi,

you put most layer options in the layer params object, and you should
set the maxExtent on the WMS layer. Something like

            tiled = new OpenLayers.Layer.WMS(
                "dwt_lata_proj - Untiled",
"http://localhost:8080/geoserver/wms",
                {
                    layers: 'DWT:dwt_lata_proj',
                    styles: '',
                    format: format,
                    transparent:true,
                }, {
                    numZoomLevels:19,
                    maxExtent: new OpenLayers.Bounds(
                        -19840232, 2028971.375,
                        -7262943, 11534410
                    ),
                    minResolution:0.5971642833948135,
                    maxResolution:156543.03390625,
                    singleTile: true,
                    ratio: 1
                }
            );

The above should work both with singleTile: true and without.

Andreas.

Hmmm. No dice with these changes incorporated. I'm not sure what is going
on. For the curious there is a live link here:

Message-ID: <CAKPYEgf7=BZwmVhPGxG9k4D+Rm-qiTK-XnDeaCdMW4dLv21Q6w@mail.gmail.com>

Hi List,

I'm using openlayers to send a WMS query based on a user-chosen extent of a
rectangular polygon. My javascript is as follows:

    // request raster layer
    rasterLayer = new OpenLayers.Layer.WMS(
           "Road layer..... ",
           "http://mysite/mapserv.cgi?map=roads.map&",
           {    layers: 'roads',
                transparent: true
                },
           {    maxExtent: centralBounds, // extents of rectangular polygon
drawn on-screen
                displayOutsideMaxExtent: false, // this is false by
default, but I tried adding it anyway
                tileSize:new OpenLayers.Size(80,80), // by default this is
256
                opacity: 0.5,
                gutter: 0}
       );

I am trying to return information from a raster using Mapserver.The query
returns a WMS layer, but only three of the four sides of the polygon have
the correct extents, and the WMS layer is a square. I've tried to
illustrated this in the below diagram:

X = requested
_____________
|                       |
|       XXXX       |
|       XXXX       |
|                       |
---------------------

Y = returned
_____________
|       YYYY        |
|       YYYY        |
|       YYYY        |
|                        |
----------------------

The extents are definitely correct, as I've used them for querying non-WMS
data that is displayed in-browser. When I make the tileSize smaller (e.g.
tileSize:new OpenLayers.Size(10,10), it fills the box perfectly. Initially,
I noticed that I was getting the following error message in Firebug:
"NetworkError: 404 Not Found - http://mysite.com/js_libraries/img/blank.gif".
My openlayers javascript is stored in the 'js_libraries' folder. I added a
folder 'img' with 'blank.gif', and my problem temporarily disappeared,
before the next page reload.

I asked a very similar question on the Mapserver list yesterday, thinking
it was a mapserver problem. I thought I had resolved it, but I have not,
and I don't think it is related to Mapserver. I'd appreciate any
suggestions - I'd prefer not to reduce tilesizes as it makes the raster
very slow to load.

Thanks,
David

You still forgot to set the maxExtent on your WMS layer!

That's still not doing it but I'm noticing that the layers turns on when I
pan to the edge of the map. What controls that?

You know, Bing is incidental in this whole thing. I'd rather be using OSM
as the background layer but I couldn't get that to work at all. Does anyone
have a working example of this with any base layer?

You didn't make the changes that we recommended. The key to solving
this is the maxExtent on the WMS layer. Here's a fiddle with a
simplified version of your code and your layer, to show that it works:
http://jsfiddle.net/ZVaXh/

It doesn't matter if it's Bing or OSM, you have to configure your WMS
layer the right way.

That's awesome and super helpful. I'm still not sure where I went wrong. I
believe that I did incorporate your maxExtent bit. Can you enlighten me? Or
point me to a resource that can help me understand?

Thanks Andreas,
Wouldn't the bbox only get me the 'rectangular' extent of the polygon and
not each actual polygon face?

Thanks Greg,
It sounds like using WFS is out of the question. The thing is I wouldn't
know how to pass the point-in-polygon client query to the server and utilize
the response. Can anyone show me how to do that?

you could use a spatial filter to let the WFS do the work
http://dev.openlayers.org/apidocs/files/OpenLayers/Filter/Spatial-js.html
eg. Intersect with the point

essentially you would send the filter then, on returning from the WFS,
test the response for a geometry, if it has one, the point is within a
polygon.
check out the examples for filter.

Hi,

the problem with the maxExtent of an overlay layer is this: if not
configured, the map's maxExtent is used. If not configured on the map,
it defaults to -180, -90, 180, 90. In Web Mercator (EPSG:900913), this
is not the whole world, but a very small area west of Africa. Usually
this results in only one tile being rendered when zoomed to the world
extent, and nothing rendered at all if zoomed to the US.

When working with base maps like Bing or OSM, it is always a good idea
to set the following in the map options:

                maxExtent: new OpenLayers.Bounds(
                    -128 * 156543.03390625,
                    -128 * 156543.03390625,
                    128 * 156543.03390625,
                    128 * 156543.03390625
                ),
                maxResolution: 156543.03390625,
                numZoomLevels: 19,
                units: "m",
                projection: "EPSG:900913"

Then at least layers without a configured maxExtent will be rendered
on the whole world. If you want to restrict the area that users can
view on the map, you can configure the map's restrictedExtent. And for
layers that are not available for the whole world, configure the
layer's maxExtent - like in the fiddle I posted.

Andreas.

topology rule enforcement. I assume you want to persist the user
generated geometries on your GeoServer as well? That can be done as
part of WFS transactions, using pre- and post-transaction hooks on the
server. The first step would be to see why your GeoServer does not
respond to WFS request, but that's a question for the geoserver-users
list."

I don't have any user generated geometries for this scenario. I simply want
to test whether a point is within a polygon geometry sitting on GeoServer. I
figured out the GeoServer is actually responding to the WFS request for the
polygon but there are LOTS of vertices so it not feasible to use the WFS
approach to determine whether the point is within the polygon.

So I created a test polygon in GeoServer called test:allPoly and a test
geometry point in OL called 'point'. Currently the point is outside the
polygon but the wfstest layer still shows up. Shouldn't the wfs polygon be
'filtered out' with the code below?

var wfstest = new OpenLayers.Layer.Vector("Flood Vector Test", {
	strategies: [new OpenLayers.Strategy.BBOX()], visibility: false,
	protocol: new OpenLayers.Protocol.WFS({
		url:  url,	
		featurePrefix: "test",
		featureType: "allPoly",	 						 
		version: "1.1.0",
		srsName: "EPSG:900913"
		}),
            filters: [new OpenLayers.Filter.Spatial({
		type: OpenLayers.Filter.Spatial.INTERSECTS,
		value: point}) 
		]
});

That's actually a good approach to proceed. I was about to recommend
WPS and the JTS:interects process that GeoServer ships with, but what
you came up with is easier.

Having said that, you only have one small typo that keeps this from
working: it's "filter" (singular), not "filters".

Andreas.

Instead of wfs you can use a WMS GetFeatureInfo Request.

I use this approach to determine which country the user clicked.

Message-ID: <1327615029-056933aca80ecd5b59a6362adfe2dbaf@infogeo.ch>

Hi all,

Is there a mean to use user-defined svg symbol for rendering vector point? I've seen a ticket about it here:

http://trac.osgeo.org/openlayers/ticket/2403

But I don't know if anything has been implemented yet. Any additional information or ressource would be greatly appreciated.

Regards,

R?my

Hi,

you can use user-defined symbols. Not defined in SVG though, but easy
to create. See http://openlayers.org/dev/examples/graphic-name.html
for an example.

Andreas.

Thanks for your response Andreas. I forget to mention I wanted to use  svg to make a basic animated symbol. I know i could achieve an animated  symbol with an externalgraphic, but I would rather use svg. Is there any mean to add an animated svg symbol to a vector symbol?

regards.

Subject: [OpenLayers-Users] wrong displayed projection
Message-ID: <20120127072740.72e0632f@vocs.unideb.hu>

Dear all,

I have a problem with projections in wms layers,
I have two wms layers from mapserv and i have two data sources
an shp and a postgis. I produced the postgis table from the shp.
When I load these two layers in qgis, they are overlapping as I
expected, but if you check it here
(http://biomaps.unideb.hu/openlayers/mapserv_test.html) the postgis
layer center is 0,0 while the shp data layer is right.



Where is the error?

Thank you very much, Miklos

An externalGraphic *can* be SVG (just reference an svg file), but then
it won't work in IE versions older than 9.

Hi,

Yes Andreas, using console as you said, I get two navigation controls, one added to map as a control, and a seccond added as a geoext action to get a pan button in the toolbar.

I've dropped the seccond because is not necesary.

Anyway, I've configured control with: mouseWheelOptions: {interval: 20, cumulative: false}

Tema: Re: [OpenLayers-Users] mousewheel jumps two zoom levels

My guess is that you have two Navigation controls. One that is added to the map by default unless you configure it with your custom array of controls, and the navControl you added.

You can check in the javascript console by trying

map.getControlsByClass("OpenLayers.Control.Navigation");

and see if it returns an array of length 1 or 2.

The obvious fix is to configure the map with your own default set of controls.

Andreas.

Hi,

Your layer declarations are a bit out of order.

lyrWMS = new OpenLayers.Layer.WMS(title, url, paramsWMS, lyrOptions)
lyrMS  = new OpenLayers.Layer.MapServer(title, url, paramsMS, lyrOptions)

Params are added to the server request, options are instructions for
OpenLayers.

paramsWMS = {
    map:'/home/banm/maps/minimal.map',
    layers:'0605',
    format:'image/png',
    transparent:true
}
WMS layers are explicit regarded as BaseLayers
if the param "transparent" and the option "isBaseLayer" is not set. 

paramsMS = {
    map:'/home/banm/maps/minimal.map',
    layers:'0605',
    map_imagetype:'png'
}

lyrOptions = {
    isBaseLayer: false,
    visibility:true,
    opacity:1.0
}

Your Mapfile should hold some more informations. 

In the layerblocks are the projection of the data not set.
PROJECTION
  "init=epsg:4326"
END

In the metadata block you should set
wms_srs 'EPSG:4326 EPSG:900913'
to support a reprojection with MapServer for these projections.

You should do a WMS GetCapabilities Request for your services to get some
configuration informations like: 

<!-- WARNING: Mandatory mapfile parameter '(at least one of) MAP.PROJECTION,
LAYER.PROJECTION or wms_srs metadata' was missing in this context. -->

Request:
http://biomaps.unideb.hu/cgi-bin/mapserv?map=/home/banm/maps/minimalp.map&Se
rvice=WMS&Request=GetCapabilities&Version=1.1.1


If you do these modifications, your postgis layer should also displayed at
the right position.
But you should declare it as OpenLayers.Layer.WMS.

Best luck
Arnd

Betreff: [OpenLayers-Users] wrong displayed projection

Dear all,

I have a problem with projections in wms layers, I have two wms layers from
mapserv and i have two data sources an shp and a postgis. I produced the
postgis table from the shp.
When I load these two layers in qgis, they are overlapping as I expected,
but if you check it here
(http://biomaps.unideb.hu/openlayers/mapserv_test.html) the postgis layer
center is 0,0 while the shp data layer is right.



Where is the error?

Hi,

I tried your Text layer in an OpenLayers sample and it worked without 
any error. The only thing I changed is your layer.txt. Your lat and lon 
column are inverted.

Best regards,
Julien

Hello all,

I'm looking to replicate the table styles on the OL examples list.

I cannot seem to get my results table to display in this "transposed"
format (where table columns become rows).  Can anyone help me achieve this?
 I can't seem to figure it out or identify it in the sample code.

Thanks,

Hi,

"type" has to be an attribute of the features.

Your code snippet works for me, if i add pointRadius or the other.

Why not use a GetFeatureInfo request using your x,y inside a small bbox and see if you get attributes returned relating to one of the polygon geometries in the WMS layer? Take your x,y point, create a small bbox round it and then use the width and height parameters to represent your point in the middle of the bbox eg.

respond to WFS request, but that's a question for the geoserver-users
list."

I don't have any user generated geometries for this scenario. I simply want
to test whether a point is within a polygon geometry sitting on GeoServer. I
figured out the GeoServer is actually responding to the WFS request for the
polygon but there are LOTS of vertices so it not feasible to use the WFS
approach to determine whether the point is within the polygon.

Subject: [OpenLayers-Users] How to Create buffer around point?
Message-ID: <1327910810.77199.YahooMailNeo@web24107.mail.ird.yahoo.com>

Hi,

?I need to implement a "simple" buffer tool. The tool should simply place a Buffer zone around the position clicked in the map when the tool is activated.

...the tool should work like this...

1. Activate tool in toolbar
2. Set Radius in map units ??
3. Click in map ?
4. buffer polygon based on the set radius is created and rendered in the map



My system is Geoserver 2.1.2 / Postgis 1.5

I have done this with an sld and also in postgis ...but I really need the real-time effect in the map!

any help or examples would be great,

yours,

Robert

We can request Geo-registered map images from one or more distributed

Try JSTS. It integrates very well with OpenLayers and contains the 
Buffer-function client side in javascript. That means it works on 
features in a vector-layer. I'm not sure if that is what you're looking 
for though.

Good luck!

Hi list !

I'm new to OpenLayers and I don't manage to display my WFS vector
layer on a OSM base layer.
So what I DO manage to do is :
- my WFS data are correctly set. I use Geoserver to provide WMS / WFS
for cadastral data.
- my js and my WMS server ARE running on the same webapp (as the final
application will be a JEE application, I use TOMCAT for both geoserver
and my app)
- I manage to display a WMS layer with the same data and transparency
- The request generated by OL and the answer of the geoserver seem
correct (some data are transfered, the GML format seems correct)

But if I don't display the WMS layer, I got nothing displayed for the WFS layer.
Last info on my conf :
- my WMS / WFS data are projected in Lambert93.
- i'm using OL 2.11 and GeoServer 2.1.3


So hope you don't mind a snippet of my code...

Hi,

you can do this with OpenLayers as well.

To get a clicked position use something like this:
http://openlayers.org/dev/examples/click.html

To render a circle buffer around the clicked position use this function:
http://dev.openlayers.org/docs/files/OpenLayers/Geometry/Polygon-js.html#OpenLayers.Geometry.Polygon.createRegularPolygon

Best regards,
Chris

Well if your server supports it, I doubt you could beat a DWITHIN WFS 
query, just make sure the distance is in native units if using geoserver.

Subject: [OpenLayers-Users] WFS not displayed (GML looks fine)
Message-ID: <1327960864781-4352042.post@n6.nabble.com>

Hi 

I have a problem with OpenLayers 2.11 talking to  WFS server provided by an
ArcGIS 10.2 server. The XML comes back from the server properly (as far as I
can tell), the features are added to the map (173 of them show up when I
examine/debug the map object in Chrome), and the number of features grows
and shrinks as I would expect it to when I zoom in and out or pan to move
features our of the map extent, but there are no features shown at all. The
styles are the defaults styles, but I have tried other default styles to no
avail.

The points come back as such:

geometry: OpenLayers.Geometry.Point.OpenLayers.Class.initialize
     bounds: OpenLayers.Bounds.OpenLayers.Class.initialize
     id: "OpenLayers.Geometry.Point_145"
     x: 4715701.3611736
     y: -11422711.075058



What is going wrong here? I can post some GML from the GetFeature request if
it would help...

Subject: [OpenLayers-Users] Printing WMS Layers - Opacity causing issues
Message-ID: <94816848A8EB3941B1E8592F425827A9B9CA440263@chex2.crdnet.ca>

Good afternoon,

I am having an issue printing layers when using opacity for WMS layer. It seems that when 2 of my area features are added to the same map only 1 of them can have opacity for both to print properly. If I add opacity to both layers, none of them print. If however only 1 layer has opacity then they both show up. Has anyone encountered this before and has any solution? The only thing I have that works is to combine both the WMS layers into one single layer  (using typenames of both to combine) except now this only has 1 opacity when both layers originally have different values.

Appreciate any advice,

My map is declared as -

map_print = new OpenLayers.Map("map", {
                controls: [],
                maxExtent: new OpenLayers.Bounds(-5621.0164289504, 5778375.8585485, 31216.186095582, 5808291.3979497),
                maxScale: 100,
                allOverlays: true,
                minScale: 125000,
                maxResolution: "auto",
                numZoomLevels: 31,
                fractionalZoom: true,
                units: "m",
                projection: new OpenLayers.Projection("EPSG:3776"),
                displayProjection: new OpenLayers.Projection("EPSG:3776")


And my WMS layers get added like so -

                        layer_Print = new OpenLayers.Layer.WMS(original.layers[num].name, wms, {
                                    layers: typenames,
                                    VERSION: "1.3.0",
                                    transparent: true
                                    },{
                                        isBaseLayer: false,
                                        singleTile: true,
                                        visibility: true,
                                        buffer: 1,
                                        ratio: 1,
                                        title: "Ortho Image"
                                    });
                                    layer_Print.setOpacity(opacity);
                                    map_print.addLayer(layer_Print);

Subject: [OpenLayers-Users] zoom to map by name of place
Message-ID: <025F41FB-0E50-4D0B-8FD6-00E190B0BE6F@gmail.com>

a'ite, this question is neither mapserver-specific nor OL-specific (two technologies that I am using gung-ho right now), but both would be involved in developing something that I describe below --

you know, how in Google Maps you can type pretty much any location's name, and if it finds a match in its database, Google Maps zooms to the boundary of that location. For example, if I type 

	http://maps.google.com/maps?q=Zurich,+Switzerland

or 

	http://maps.google.com/maps?q=Dane+County,+WI

or 

	http://maps.google.com/maps?q=New+York+City

the map zooms to the bounds of that location. This is what I want to develop, for the entire world. I guess the starting point would be the geonomes database, except, if I understand correctly, geonames does not have the bounds of locations. Instead, it has only the centroids of locations.

A better way might be something like the following --

I am using Google Maps as my base layer anyway. Could I somehow submit a search through my application to the Google Maps base layer, return the bounds and zoom to that?

Thoughts? Suggestions?

Hi,

I have created one OpenLayer script with several layers. One of this layers
comes from a remote Map Server. Now, I have achieve show all the layers,
but when I try obtain information from the remote layer, the function do
not returns anything.

Exists some meaning to read two or more url's at the same time? Thanks

My code is like this,

var RemoteLayer =
   new OpenLayers.Layer.WMS("Remote",
              "http://ovc.catastro.meh.es/Cartografia/WMS/ServidorWMS.aspx

                         transparent : true},
             {isBaseLayer : false,
              singleTile:true,
             ratio: 1});

...

info = new OpenLayers.Control.WMSGetFeatureInfo({
                  url : '/cgi-bin/mapserv.exe',
  title : 'Info',
  layers : [ LocalLayer1, LocalLayer2, RemoteLayer],
queryVisible : true,
vendorParams : {map : 'mapfile'},

     if(event.text!="")
     {
 var popup = new OpenLayers.Popup.FramedCloud("Datos",
    map.getLonLatFromPixel(event.xy),
 null,
 event.text,
 null,
 true);

popup.autoSize = true;

map.addPopup(popup, true);
}
}
}});

Message-ID: <C2601C366739884D80955B2A51F8DF98054535@Hermes.columbia.ads.sparta.com>

I have a vector layer being created from a KML file via an HTTP protocol, and I'm trying to figure out how to get a custom icon to be displayed for all point in the KML file.

Example URL to icon: http://www.mysite.com/icon.png

How I create the KML Layer:

var layer = new OpenLayers.Layer.Vector('mylayer', {
    strategies: [new OpenLayers.Stategy.Fixed()],
    protocol: new OpenLayer.Protocol.HTTP({
        url: 'http://www.mysite.com/kml.kml',
        format: new OpenLayers.Format.KML({
            extractStyles: false,
            extractAttributes: false,
            maxDepth: 0
        })
    })
});

I've tried creating a style and a style map and adding it to the layer, but I can't seem to get anything to work.

Hello,

I want to fire the getfeatureinfo event of the

I have x and y of a point (from Google geocoder) and want to display the
featureinfo at this point without clicking on the map.

Has anyone an idea?

Any idea?

The stock android browser pre-honeycomb is absolutely woeful! It doesn't
support touch events and has lots of quirky interactions with JQuery Mobile.
I expected better from a WebKit-based mobile browser (and from Google, the
same people who made Chrome!).

Anyway, they cleaned up their act since and the browser in ( Honeycomb / Ice
Cream Sandwich ) is top notch.

Sad to say, those on gingerbread (ie. The majority of Android users) will
have to deal with the degraded touch-less experience. So you should keep
basic navigation controls in your map viewer as a fallback.

The problem also apply on maps.google.com, so it's not related to open
layers

Subject: [OpenLayers-Users] Move listener curious behaviour
Message-ID: <CAPitpCb2Ka-5cor-vU+-N4bSiOP-jcDEmXHgDjpP-fkK53qUxw@mail.gmail.com>

Hello all,

I have spotted some curious behaviour with the move listener on the
map object. (using OL 2.11).

The code is pretty simple..

map = new OpenLayers.Map({
    controls: [new OpenLayers.Control.Navigation() ],
    div: "map",
    eventListeners: {
        "move": updateCoord
    }

});

and the updatecoord function is just this:
   function updateMap() {
                 var tlPixel = new OpenLayers.Pixel(10,10);
                var tl = map.getLonLatFromLayerPx(tlPixel);
                document.getElementById('output').innerHTML = tl.toString();
}


The problem I'm seeing is that the coordinates are only updated every
time I zoom, rather than everytime I pan / drag etc...

Any ideas?

Thanks,

Toby

Hi,

getLonLatFromLayerPx is an internal function that does not what you
want and should not be used by applications. Try getLonLatFromPixel
instead.

Hi,

the least dirty way to do it is to fire a click event on the map:

map.events.triggerEvent("click", {xy: map.getPixelFromLonLat(lon, lat)});

Hi,

I am searching for a solution exactly the same as described it in the
previous post.
After 18 TMS zoom levels i want to change to zoom level 19 in an WMS.

Any new suggestions?

Cheers

Thank you Andreas,
but when the the lon, lat coordinates are outside of extent of the map?
I think about a auxiliary map with a big extent...

In this case you could open a popup at the xy position. This will pan
the map into view. And on moveend, you fire the click event. Not sure
if this workflow meets your requirements though. If not, you'd have to
pan the map into view programmatically before firing the click event.

KML specifies its own icons using <IconStyle> etc.
You could edit the KML.
But if you want to override the KML, you'll have to create your own custom
KML renderer by editing the OL code.

Hi, I appreciate the response.

This is actually inly happening when I use Internet Explorer 8 to print (which unfortunately is still the default browser here). I have also tested the exact same code using Chrome, Firefox and Internet Explorer 9  and the print works. But when I use two layers on a map and both have opacity then only one shows up properly when printed using IE8. Any work around for this?
