Subject: [OpenLayers-Users] Problem with lining up google map layers and
	MApServer served layer
Message-ID: <004d01c893d0$f67f5600$e37e0200$@gadenz@jrc.it>

Hi all!

 

When overlaying a mapserver layer to google maps data there is a shift. It
seems that the World Map data coming from http://world.freemap.in/tiles/
line up mwith the data source I am publishing (the yellow one) and they are
shifted of around the same amount respect to the base google map layers.

 

The same effect is visible on the spherical-mercator.html example file.

 

In MapServer I used the following string:

 

  PROJECTION

         "+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0
+y_0=0 +k=1.0 +units=m +nadgrids=@null +wktext  +no_defs"

  END

 

Any way to solve this?

Subject: [OpenLayers-Users] OpenLayers 2.6 RC1
Message-ID: <20080401122349.GE21204@metacarta.com>

The OpenLayers Development Team is proud to announce the first release
candidate of OpenLayers 2.6.  As of 2.6-RC1, the OpenLayers 2.6 release
closes 282 outstanding tickets, 75% more than any OpenLayers release to
date. 

For information on possible changes that will need to be made between
this version of OpenLayers and previous versions, please look at the
Release notes, available at the Release Notes information[1].

We invite you to help us test the 2.6 release candidate! To test 2.6 in
your applications, include the following tag in your OpenLayers-powered
page:

  <script src="http://openlayers.org/api/2.6-rc1/OpenLayers.js"></script>

As always, the source is available at http://openlayers.org/download/.
Bug reports can be filed in Trac, under the 2.6 version and milestone.

This is a large release: the largest of any OpenLayers release to date.
We encourage widescale testing in an effort to shake out any bugs in
upgrading existing applications to OpenLayers 2.6. This release features
a number of major developments, including:
  
  * Integration of the CloudAmber "Google Like" popups for advanced
    visual display of information in popups
    * Resulting improvements throughout all popup code, including
      autosizing popups to the content they contain.
  * Improved panning of commercial layers like Google Maps and Yahoo! Maps
  * Animated panning of the map, using OpenLayers.Tween support
  * Layer Image transitions, for keeping images visible when zooming
    to allow smoother transitions
  * Client side reprojection support using built in transformations for
    spherical mercator, or the proj4js library for other projections.
    * Support for reprojecting vector data layers
    * Support for reprojecting user-facing controls like mouseposition
    * Support for programatically reprojecting points and geometries 
  * Improved OpenLayers Styling, including:
    * OpenLayers.Style, OpenLayers.StyleMap, OpenLayers.Rule support
      for improved feature-attribute based styling
    * SLD read/write support 
  * Support for reading and writing multiple versions of WMC.
  * Improved KML support, including KML styling support.
  * Improved GeoRSS Format support, including GeoRSS GML read support.
  * New ScaleLine Control for displaying visual scale
  * New NavigationHistory control for map history navigation
  * Localization/Better Internationalization support
  * Layer support for MapGuide Open Source 
  * A number of new / improved handlers to make handling user
    interactions easier
     * Handler.Hover
     * Handler.Click
     
There are a number of people who have really made this release happen.

TOPP and MetaCarta worked together to arrange for several day long 'hack
session' in TOPP's office in New York City with myself, Erik, and Tim
Schaub: This session was extremely productive, and ended up producing a
huge amount of code for the relatively little amount of time we were all
able to get together. Without that several day long session, I think
we'd still be far from a release. Many thanks to Chris Holmes from TOPP 
and John Frank/Josiah Strandberg at MetaCarta for supporting that effort. 

A list of people who stic out to me as having helped especially to make
this release happen:
 * Andreas Hocevar (TOPP)
 * Tim Schaub (TOPP)
 * Roald DeWit (LISAsoft)
 * Bart van den Eijnden (OSGIS)
 * Erik Uzureau (MetaCarta)
 * Eric Lemoine (Camptocamp)
 * Pierre Giraud (Camptocamp)
 * Fred Junod (Camptocamp)
 * Paul Spencer (DM Solutions)
 * Mike Adair (DM Solutions)
 * All the other testers, commenters, etc.

This is by no means a complete list: There are dozens of people who I
have interacted with that deserve to be on this list, but these are the
ones who stick out in my mind as being a major boon to the current
release.

Additionally, I'd like to speak high praises about the users who helped
out during the hackathon during FOSS4G. Although it's hard to believe,
the FOSS4G hack session was during the current (2.6) release cycle, and
we picked up some really great additions to the library, like our new
Fancier examples list http://openlayers.org/dev/doc/examples.html  as a
result of the hard work put together in a single day by a bunch of
people who had never touched OpenLayers before. So thank you to those
people as well.

Further RC announcements will be sent only to the Developers list:
anyone interested in tracking the progress to a final release should
subscribe[2] to that list.

We look forward to your feedback on this release.

The attached image is a screen shot of an area in the South of Argentina. It
seems that the overlay layers (my mapserver layer and the worldmap) has a
shift toward North related to the base layer (the grey google map).

The link you sent
(http://openlayers.org/dev/examples/spherical-mercator.html?zoom=11&lat=-5.1
4976&lon=-35.69046&layers=B0000000000TT) does not work for me both in IE and

Message-ID: <200804012004.13618.research@leviathanchile.org>

Hi All,

I am new at OpenLayers and I think this is awesome. I am trying to build a 
small GIS for an ONG using the same layers used on the Openlayers homepage. 
The big step will be to connect it to a database to store the markers. But in 
a later step.
I am so sorry to bother you with such a question. It may be very simple but I 
have had nightmares looking for a solution... Here is my problem:

I have gotten two layers working using "map.addlayer()" for each layer instead 
of using "map.addlayers()" for all. I do not know why, if I use "AddLayers", 
I only get a blank map (white) with only the blue buttons on the left up 
corner.
Also, and maybe related, I got the center and zoom of the map working, 
however, the next controls do not work/show in the map:
ScaleLine, MousePosition, OverviewMap.

Here is my code (from: http://www.cmmrleviathan.org/ciencia_GIS2.htm):

<script type="text/javascript">
var map, ol_wms, jpl_wms;
function init(){
map = new OpenLayers.Map('map', {'maxResolution': 1.40625/2});
jpl_wms = new OpenLayers.Layer.WMS( "Mapa 
Satelital","http://labs.metacarta.com/wms-c/Basic.py?", {layers: 'satellite', 
format: 'image/png' } );
map.addLayer(jpl_wms);
ol_wms = new OpenLayers.Layer.WMS( "Mapa 
Vectorial", "http://labs.metacarta.com/wms-c/Basic.py?", {layers: 'basic', 
format: 'image/png' } );
map.addLayer(ol_wms);
map.setCenter(new OpenLayers.LonLat(-79, -29), 2);
map.addControl(new OpenLayers.Control.LayerSwitcher());
map.addControl(new OpenLayers.Control.ScaleLine());
map.addControl(new OpenLayers.Control.MousePosition());
map.addControl(new OpenLayers.Control.OverviewMap());
}
</script>

any help or idea would be very much appreciated...

Best regards,
Gian Paolo

I am using a geocoder to go to an address  but it always returns to me lat
longs which is normally just fine. However, I am also using a
shericalMercator base and would therefore like to transform the single point
from Lat Longs to Eastings Northings in sphericalMercator projection. Dose
anyone have a method or the formula to do this?

Are you using 2.6 yet? It's in there: just:

 lonlat.transform(new OpenLayers.Projection("EPSG:4326"), new
 OpenLayers.Projection("EPSG:900913"));

If not, of course, you can use the forwardMercator and inverseMercator
functions on your commercial sphericalMercator layer. (See
Layer/SphericalMercator.js.)

Chris,

Thanks for that. I upgraded to 2.6. and it is stable at least for what I am
doing and the transformation worked a treat.

When is 2.6 scheduled to be published?

As I'm sure you saw earlier today, 2.6 only reached RC1 this morning.

In general, our time from RC1 to release has ranged from 1 week to 6
weeks.

My hope is that this will be a short RC cycle. However, it is a
significantly larger release than any OpenLayers release in the past:
Although there is less change in core functionality, we may still have
unforseen problems / regressions in code that we want to fix in 2.6 that
slow the final release process.

I won't give a date: I would be wrong. I will say "As soon as it makes
sense" -- which means the more feedback we get from our users on things
that work, the better and sooner we can release. So thank you for your
feedback.

As always, the users list will be notified when the new release is
available.

Message-ID: <9C37154DC7C8074FBC34214363755B7C1EB341@ITB-SVR-01.itbeyond.local>

I have been following the development around FramedClould for the last
few days and now see that it is published in the trunk. Excellent piece
of work to all concerned.

 

I cannot profess to be a JS expert nor am I fully into OL code as yet -
I am getting there but thought it best to ask this question before I
start adjust the code. Is it possible to transfer support of the GEORSS
markers from popup to FramedCloud popups. This would sit closer to other
implementations. Maybe there is a simple way to do this however as I
stated I am not fully into it just yet.

 

Any help or thoughts on this would be great!

Doesn't "map.addLayers([jpl_wms, ol_wms]);" work?

I copied/pasted your code in OpenLayers' wms.html example and it just
worked. The controls are there.

When I load your web page in FF, FireBug shows this error:

OpenLayers.Control.ScaleLine is not a constructor
map.addControl(new OpenLayers.Control.ScaleLine());

It seems to me that you're missing controls in your OpenLayers.js
build. You can try to use
http://dev.openlayers.org/nightly/OpenLayers.js instead of your
(custom) OpenLayers.js build to make sure that's your problem.

Hi,

You can't use the ScaleLine control because you're using and old version of
OpenLayers (http://www.openlayers.org/api/OpenLayers.js version 2.5). The
ScaleLine control was added after the 2.5 release.

You have to use a more recent version of OpenLayers, the new stable release is
not ready yet but you can use the release candidate:
http://openlayers.org/api/2.6-rc1/OpenLayers.js
But this is not the final code !! When the final 2.6 will be released this url
will become obsolete ...

Message-ID: <b3b5e5690804012351p4effb730o1c42555e515191a2@mail.gmail.com>

The markers I'm currently using are those diamond shapes ones. Are there any
better looking free-to-use markers out there?

I am right to assume I can't just use Google's?

thanks

Message-ID: <9C37154DC7C8074FBC34214363755B7C1EB363@ITB-SVR-01.itbeyond.local>

Hi,

 

I was needed to add support for right mouse click events and also the
right mouse double click zoom out function. I have made the required
mods to the code to support this and was wondering (as I am un familiar
with the process) how to submit the mods for consideration in the
overall project. There may need to be a compliance check done 

 

There are updates to Events.js, Controls/Navigation.js, Handler/Click.js
and also a one liner in Map.js.

 

The updates I have developed add support for single and double right
mouse events. I have mapped the zoom out to double right click in
Navigaton.js. 

 

I noticed the ticket for this task and the expected release in 2.7
however I wondered if we may be able to sneak it into 2.6. Anyway can
someone tell me what the process is to have the mods evaluated and I
will gladly comply.

David,

you can attach your patch to the ticket.  The feature list for 2.6 has  
been frozen for a little while and now that RC1 is out, it is unlikely  
that this will make it in to 2.6 as it is a new feature, not a bug or  
regression.  At this point, only bugs (fairly critical ones) and  
changes in API behaviour from previous versions would be considered  
for inclusion in 2.6.

Nothing in /api/ Ever goes away: You can continue to use 2.6-rc1 for all
time, but it would not be wise to. However, it's only obsolete in the
same way that /api/2.4/ is: You can safely use this in your application,
you should just be aware that as soon as 2.6 is released, it will make
sense for you to switch.

What 'other implementations'?

So, I have a couple feelings on this. 

1. The way that we do Layer.GeoRSS right now is an unfortunate
   situation: if we were to 'do it all over again', we would do it very
   similar to the new examples/sundials.html, by having a single layer
   that wrapped up the data display and a selectfeature control to open
   a popup. I *highly* recommend looking at this example: It's a few
   more lines of code than setting up a layer.GeoRSS, but it's *way*
   more extensible, since you have complete control over just about
   everything.

2. If you don't like this, and want to use layer.georss with
   framedclouds, then you can do this at this time:

    OpenLayers.Feature.prototype.popupClass =
      OpenLayers.Popup.FramedCloud;

   I think this should work as a first order approximation. However,
   there could be problems with this, and it's not really 'supported'
   because we don't do it in our tests or examples, so it is, at the
   moment, somewhat at your own risk.

I still recommend #1 strongly for anyone doing work with GeoRSS for the
long term -- your next question will be "how do I use different icons
for entries from different categories?", and that one can't be answered
nearly so easily.

Good luck, and Best Regards,

Are you using trunk/2.6, or 2.5? I think the answer is the latter, and
if so, the answer is "Upgrade."

If the answer is "The former", then the answer is "We thought the code
did that: Please open a ticket for 2.7."

In general, the process for creating and submitting patches is outlined
at http://trac.openlayers.org/wiki/CreatingPatches . You should also
fill out and submit a CLA:

The feature freeze for 2.6 was 6 weeks ago: so unless you have a time
machine, this won't be in 2.6.

Thanks for your interest,

I'm using 2.5, thanks for the very quick response!

I don't think I'm in a position to upgrade right now,
but as I know that there is a solution, this shouldn't
be a major issue.

If you do find some alternative icons that are available free of use,
please let us know.
just like we will be setting up an addins/customPopups directory, I
think it would be
a good idea to have an addins/customMarkers

You might want to check out what ka-map has, it is likely we can use those.

You might also want to check out msCross, they have a simple clean 
balloon with a shadow thats looks nice. 
http://sourceforge.net/projects/mscross I would think that we can ask 
either of these for permission to use their icons.

Another option might be to ask the community if any of the graphic 
designers out there would like to create some sample icons that they 
would be willing to contribute to be a part of OpenLayers. Run a contest 
and have the community vote on them.

Jim,

The default build tools, used to create the 'shipping' versions of
OpenLayers, use a Python port of jsmin. (This file is available in the
tools/ directory.)

jsmin is not designed to be an obfuscator: just a basic compressor.

It is possible to use any Javascript compressor to compress OpenLayers
code, if jsmin does not fit your needs: simply use the
./buildUncompressed.py tool in the build directory to build and
uncompressed library, then run the result through your compressor of
choice.

Subject: [OpenLayers-Users] Problem with map server single tile
Message-ID: <004701c894cc$6addd020$40997060$@gadenz@jrc.it>

Hello!

I have a problem of positioning with a map server single layer over a
spheric mercator base layer.

The definition of the map server layer is:

// create dma default layer
dmadef = new OpenLayers.Layer.MapServer( "Digital Map Archive Default", 
 
"http://139.191.68.15:8000/cgi-bin/mapserv.exe?map=C:/MS_MapFiles/dmaclient/
dmadefault.map&mode=map", 
      {layers: '0,00,1,2,3', 
      reaspect: false, 
      transparent: true,
      isBaseLayer: false,
	wrapDateLine: true},
	{singleTile: true,
	ratio: 1,
	opacity: 0.3,
	transitionEffect: 'resize'}
      );

When the application starts (the initial extent is set using the
map.zoomToMaxExtent() method) the single layer is positioned on the right
side of the screen and it goes out of the page for half of its width.

When I zoom in thinghs work perfectly.

If I use a tiled layer every single tiles positions correctly.

In fact I would like to use tiles but in that case I have a lot of problem
with myltiple labels.

Suggestion?

Simone

My 2 cents:

I load the GeoRSs through a GML layer using a GeoRSS format. I modified a
bit the GeoRSS format class to give the user the possibility of defining the
field he wants to use for symbolizations.

This is the html that works for me:

var in_options = {
             'internalProjection': new OpenLayers.Projection("EPSG:900913"),
             'externalProjection': new OpenLayers.Projection("EPSG:4326"),
             'type':'eventType alertLevel'
        };
        
        // create a GeoRSS layer
        // Inorder to accomodate all the possible geometry type the layer
must be a GML layer with a GeoRSS format
        // defining styles
 	    var styleMap = new OpenLayers.StyleMap({
                fillOpacity: 1,
                pointRadius: 10
            });
        // create a lookup table with different symbolizers for 0, 1 and 2
        var lookup = {
            EQGreen: {externalGraphic: "images/eqgreen.jpg"},
            EQOrange: {externalGraphic: "images/eqorange.jpg"},
            EQRed: {externalGraphic: "images/eqred.jpg"},
            TCGreen: {externalGraphic: "images/tcgreen.jpg"},
            TCOrange: {externalGraphic: "images/tcorange.jpg"},
            TCRed: {externalGraphic: "images/tcred.jpg"},
            FLGreen: {externalGraphic: "images/flgreen.jpg"},
            FLOrange: {externalGraphic: "images/florange.jpg"},
            FLRed: {externalGraphic: "images/flred.jpg"},

            VOOrange: {externalGraphic: "images/voorange.jpg"},
            VORed: {externalGraphic: "images/vored.jpg"}
        }
        // add rules from the above lookup table, with the keyes mapped to

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

                                 "<div style='font-size:0.8em'><A

feature.data.description+"</div></div>",
                                 null, true, onPopupClose);
        feature.popup = popup;
        map.addPopup(popup);
    }
    
    function onFeatureUnselect(feature) {
        map.removePopup(feature.popup);
        feature.popup.destroy();
        feature.popup = null;

Message-ID: <000001c894d5$73fa7d80$5bef7880$@gadenz@jrc.it>

Hello again.

 

I'd like to modify the LayerSwitcher control to:

- include the management of the transparency of the layers directly in
there;

- add buttons for each layer for reading metadata and similar information

 

Anybody thought already about it? 

 

How is the list of the layer written into the component?

 

Thanks

Message-ID: <6e9b30fb0804020957g2bc432dfqda11c3915809a91c@mail.gmail.com>

I have several custom enhancements I have made to the source code.  With the
onset of a new release I would like to put these in a separate file and
"override" the code that is in the release.  For instance I might want to
add the following function, just an example, it might already be in there to
Map.js

getLayerByName: function(name) {
       var foundLayer = null;
       for (var i = 0; i < this.layers.length; i++) {
           var layer = this.layers[i];
           if (layer.name == name) {
               foundLayer = layer;
           }
       }
       return foundLayer;
   },
Would I do something like the following in a .js file to be called after
Openlayers.js?

Map.prototype.getLayerByName=function(name) {
       var foundLayer = null;
       for (var i = 0; i < this.layers.length; i++) {
           var layer = this.layers[i];
           if (layer.name == name) {
               foundLayer = layer;
           }
       }
       return foundLayer;
   }

How do you do this?

Message-ID: <47F3D65C.5020805@sms.ed.ac.uk>

Hey,

Has anyone managed to load georeferenced map tiles generated by 
gdal2tiles into OpenLayers?

This is the code generated by gdal2tiles: 
http://www.thematicmapping.org/maptiles/naturalearth/openlayers.html
Only pixel based view is supported, which makes is difficult to combine 
map tiles with other data layers.
Is there an alternative way of loading map tiles? Or is there a better 
alternative to gdal2tiles?

About GDAL2Tiles:

Thanks,
Bjorn

I saw this same thing mentioned in some blog posting somewhere, and I
thought "huh, someone is confused": in fact, this lines up exactly with
the TMS spec, and can be used with practically no changes by the default
TMS layer:

http://crschmidt.net/mapping/naturalearth.html
 
 You just need to specify a serviceVersion of '.' .  (This is pulled
 almost exactly from the TMS example that ships with OpenLayers.)

> Is there an alternative way of loading map tiles? 

Other than the TMS layer?

> Or is there a better alternative to gdal2tiles?

None needed, so far as I can tell.

For your information, there's currently a method (getLayersByName [1])
that is already written and might match your needs.

Wow - it works!

Thanks a lot! OpenLayers keeps impressing me.
And, I'm often very confused ;-)

Subject: [OpenLayers-Users] Openlayers 2.6 - zoomLevels.html
Message-ID: <6e9b30fb0804021413p733b032chc55c6a7306536051@mail.gmail.com>

I want to make the panZoomBar contain specific scales.  How do I do that?

I have tried the following the the zoomLevels.html

        var lon = 50;
        var lat = 0;
        var zoom = 0;
        var map, layer;
        function init(){
            OpenLayers.DOTS_PER_INCH = 72;
            var options = {
                          scales: [50000000, 10000000],
                            controls: [new
OpenLayers.Control.MouseDefaults()]
                          };
            map = new OpenLayers.Map( 'map' , options);
            map.addControl(new OpenLayers.Control.PanZoomBar());
            layer = new OpenLayers.Layer.WMS( "OpenLayers WMS",
                    "http://labs.metacarta.com/wms/vmap0", {layers:
'basic'});
            map.addLayer(layer);

            map.setCenter(new OpenLayers.LonLat(lon, lat), zoom);
      }

I expected to see only two bars in the PanZoomBar.  What do I need to do to
see that?

I think that the correct param is resolutions and not scales
so
resolutions: [50000000, 10000000],

Thanks Christopher.

On your example when I click on the zoom bar nothing happens.  The slider
works but the click on the zoom bar doesn't.

You can never click on the top 'rung' of a zoombar. If that's a problem
for you, feel free to open a ticket for 2.7.

Even when I slide the slider to the top rung and click on the bottom rung
nothing happens.

So I tried adding the following scales:

scales: [50000000, 30000000, 20000000,10000000],

Totally screwy mouse clicks.  When I click L2 it goes to L3.  I have to
double click some of the bars to get them to zoom.

Thanks for the input. I'll check them later on. I might also look into
commissioning a designer to create some markers for OpenLayers. That'd be
cool.

I found the problem.  Somebody changed this line in PanZoomBar.js

FROM:

var levels = Math.floor((y - top)/this.zoomStopHeight);

TO:

var levels = (y - top)/this.zoomStopHeight;

This is causing the problem.

Message-ID: <6e9b30fb0804030856q2a36128bh3bf2bda0746d5a57@mail.gmail.com>

What I was hoping for with 2.6 was the following:

        var map, layer;
        function init(){
            var options = {
               scales:
[55468034,13867008,3466752,108336,54168,27084,13542,6771],
                projection: "EPSG:900913",
                units: "m",
                maxExtent: new
OpenLayers.Bounds(-20037508,-20037508,20037508,20037508.34),
                controls: []
            };
            map = new OpenLayers.Map( 'map' , options);
   map.addControl(new OpenLayers.Control.PanZoomBar());
      layer = new OpenLayers.Layer.Google("Base",{'sphericalMercator':
true});
            map.addLayer(layer);
            map.zoomToMaxExtent();
        }

Should show 8 bars on the panzoombar.  But it still shows the default number
of zoom levels defined when you say sphericalMercator: true.

Is there any way to do this without customizing the panzoombar?

Thanks!

Math.floor is called (if your map doesn't have fractionalZoom) two lines
later, on the zoom. Can you explain why this is a problem in your setup? 

A more complete HTML example with the behavior you expect and the
behavior you're getting would be helpful.

Was there something that made you think it would?

There is no way to define anything other than factor-of-two zoom changes
on a Google Maps baselayer in OpenLayers: hacking the zoombar won't help
you here.

Subject: [OpenLayers-Users] Closebutton Callback on popup?
Message-ID: <40e43de90804030912r559a8eb7ic1c168e13e916796@mail.gmail.com>

Hello,

I am creating popups through the Feature object:

this.popupClass = OpenLayers.Popup.FramedCloud;
this.popup = this.createPopup(true);

The 'true' parameter sets a close button on the popup.
I need however to do other cleaning stuff when a popup is closed. Is
there an official way to set up a callback function during the
creation of the popup? I would like to avoid using
this.popup.addCloseBox if I can hepl it.

Thanks,
Guillaume

Try clicking on the third zoom level.  It does nothing.  Then you
click on the second and the zoom goes to the third.  It is off by one
every time.  Then go the other direction.  More havoc.

Actually I have quite the hack to do this.  But I was hoping not to
hack anymore!  It looked so promising to be able to define scales on
the map that I was hoping it would carry over.

Thanks!

There is no API through the feature.createPopup method. However, I would
recommend simply reading that code, and reimplementing it in your
application code (since you have a feature handle anyway): there is an
argument to popup creation, just not one to the feature wrapper around
it.

Hi all,

This might be my issue with not understanding the changes related to the 
themes and styles and overriding the editing toolbar.

http://imaptools.com/~woodbri/edit/index26rc.php?extent=-129,19+-60,60

It looks like two of my icons are missing because it is trying to pull 
them from the default theme instead of my override theme.

Did I miss this up somehow?

OK, as a work around, if I change all occurrences

olControlEditingToolbar   to   olControlMyEditingToolbar

in my code and override style.css it displays the right thing. But I 
think some of the override theme stuff is broken 2.6rc1.

The above url now works with these changes, but the following shows the 
case where it is broken:

Hi,

I'm currently testing the capabilities of doing thematic mapping with 
OpenLayers.

This is a proportional symbol map based on GeoJSON encoded data:
http://thematicmapping.org/experiments/openlayers_propsymb.htm

My question: Is there a way to keep the relative size of the symbols 
when the users zoom in/out?
(symbols should keep their size relative to the size of the countries).

Do you have their credentials? (I'd hope, for security reasons, that you
wouldn't, but if you do, what you want is possible. Otherwise, it's not.) 

If you do have their credentials, you can generate URLs like:

  "http://username:password@example.com/wms/foo"

And their credentials will be passed by the browser.

This isn't helpful for you. You can already do this for XMLHttpRequest
in trunk (though you'd have to try harder): this doesn't really fix
things in any way.

The latter.

Right answer: Use single signon: Kerberos, Active Directory, etc.  
Wrong answer: Integrate user credentials in the URL.

Answer that helps you: Depends on how you're doing auth. Would need more
information on that for you to get helped.

I've just checked: This code works exactly the same in 2.5. So
regardless of how broken it is, it does not appear to be a regression,
unless you can offer evidence otherwise.

(I downloaded broken.php, pointed the CSS to your files, and then
changed the OpenLayers file to reference 2.5 via /api/OpenLayers.js.)

Chris,

Thanks for your reply.  We don't have the credentials of the end user
that is logged into the web app, which is a good thing as you say, but
at this point we really just need to impersonate the user to the WMS
server based on a couple different authorization roles that apply.  So
we could pass credentials through the URL but our security standards
won't allow us to do it in clear text.

To answer your other questions, we do use Active Directory for
authentication but we do not yet have single sign-on.  Both the web
application using OpenLayers and the WMS server use AD authentication,
but they run on different web servers.  In fact, the web app runs on
Apache and the WMS server runs on IIS.  The web app uses an Open LDAP
interface to perform authentication and the IIS server uses the
out-of-the box Windows AD authentication when you disable anonymous
access to your web site.

Does that give you any other ideas?

Thanks again,

Paul

Right answer: Use single signon: Kerberos, Active Directory, etc.  
Wrong answer: Integrate user credentials in the URL.

Answer that helps you: Depends on how you're doing auth. Would need more
information on that for you to get helped.

Christopher,

Thank you for taking a look at this. I will accept your good judgement 
on this and try to dig into this a little more for my own education.

The one thing I noticed while poking at this in FireBug and Inspecting 
the DOM, was that the missing icons had the CSS from the 2.6rc1 
style.css while all the others had the CSS applied from my override CSS. 
So by changing the CSS class to olControlMyEditingToolbar I seem to have 
avoided that conflict. I guess I'm not sure how the CSS rules get 
applied in this case when you have two stylesheets both with the same 
class names.

Thank you again for your effort and assistance.

-Steve

AFAICT there's no way to style features based on the current zoom level.

But I guess you should be able to implement this in your application
code, by registering to the zoomend map event.

Hi Stephen,

you can also try using !important in the stylesheet you want to prevail, 
so you don't need to change the css class names, example:

.olXXX {
  width: 200px !important;
  height: 200px !important;
}

Best regards,
Bart

I'm pretty sure that the StyleMap/Style/Rule system is designed exactly
for that, but I have no idea how it's supposed to work.

I would say "look at http://trac.openlayers.org/wiki/Styles", but I see
that it's using Rules for styling, which I think was recently decided
would be unsupported in OpenLayers 2.6, so I don't know what you're
actually supposed to do.

A similar thing can be seen when using Internet Explorer to look at 
http://aardbodem.nl/node/3: when dragging a zoom box with the mouse, it 
will appear around 200 pixels to the left of the cursor.

I expect the reason lies in the theming of the site, but I don't know where to 
correct it.

There's no reason that credentials as I stated need to be in clear text:
the browser uses this username and password as auth for the request, it
doesn't send them as part of the URL to the server. But it probably
doesn't solve your problem anyway. 

If your application server has the ability to get to all the information
(as in: it has superuser access) then you might be best off simply
proxying the IIS requests through something on the Apache server. Apache
server uses the superuser credentials to access the IIS, download the
data, and must then enforce the security requirements of the remote
server.

I expect that what this means is: 
 * The Apache server is doing authentication using LDAP, not Active
   Directory (with the AD server as an LDAP backend)

 * What you actually want is:
   http://www.microsoft.com/technet/prodtechnol/WindowsServer2003/Library/IIS/523ae943-5e6a-4200-9103-9808baa00157.mspx?mfr=true

"""Unlike Basic authentication, Integrated Windows authentication does
not initially prompt for a user name and password. The current Windows
user information on the client is used for Integrated Windows
authentication."""

However, setting this up on both the IIS server and the Apache server
would probably be a lesson in active directory that you may not be
interested in:
http://www.onlamp.com/pub/a/onlamp/2003/09/11/kerberos.html
might be a starting point for understanding it and making that decision
on the Apache side.

My guess is that it's related to:

style.css (line 401)
body.sidebar-left #center {
margin-left:-210px;
}

or possibly the corresponding margin-left of 210px on '#squeeze'.

Since you say about 200px, and I know that IE has... 'issues' with
margin calculatino. Is it just IE6, or does IE7 suffer similarly?

I can think of another option, but it is a fairly big change of course.

Instead of sending RSS to OpenLayers and building the vector features, you
could use MapServer to create a transparent WMS layer with your features in
it.  That way, you could use LAYER SYMBOLSCALE to scale your symbols.

Bjorn
The correct way to handle this is to attach an event handler to the endzoom
event.
This event should manage the size of the symbols so that they are
propotionally sized.
Choose the zoom level at which the symbol renders at the right proportion,
this will be your refernece zoom level. Then size the symbol propotionally
the ratio of resolution @ current zoom level / resolution @ reference zoom
level. Depending on the event firing order, you may also need to call
redraw() on your vector layer.

Subject: [OpenLayers-Users] Markers vs Features?
Message-ID: <20080404140946.GA10631@fourddev.com>


Hi:

We have an application framework that we've decided to port from Google
Maps 2 to OpenLayers, and so far it's been pretty painless. From the map
perspective, our application provides for real-time marker updates via
GPS devices, user-created markers w/custom icons, user-created vector
features (lines, areas, polys), custom maptile sets, etc.

Coming from the GMap2 world, I initially ported our code to work with the
OpenLayers.Marker class, where it had been previously using GMarkers. I
knew that I would be using Features to support the vector functionality,
but when I started looking at how to make certain user-created Markers
draggable (as we had before with GMap2), I started getting lost.

I guess my question is, coming from a Google Maps 2 world, it seems like
a GMarker is more like an OpenLayers.Marker except for being able to
drag it around, in which case it looks like I should use
OpenLayers.Features instead for everything. But then I'm getting
confused by the fact that a Feature attaches to a particular Layer, when
we intended to have multiple base layer options for the user to pick
from.

And finally, I don't understand why a Feature has it's own lonlat that
could be different from the one the Marker has....?

Can anybody help clear this up for me?

Thanks for your time.

Is it possible to have FramedCloud popups autosize with images without
specifying img width/height?

The images I am using do not all have the same size. It would be great if it
did autosize.

If not, is there a work around? Or any advice on how to change the existing
code would also be appreciated.

Is there a reason that you treat Markers (icons) and vectors
(points/line/polys) differently?

If we were to look at The Way Things Should Probably be, I would say
that Markers are only there as a historical thing. "Everything should be
using Vectors" -- *including* things that you want graphical images for.

As an example of that: 

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

These are vector features, with an external graphic styling object. 

(Style properties are, specifically:

{"graphicOpacity":1,
 "externalGraphic":"http://maps.google.com/mapfiles/kml/shapes/sunny.png",
 "graphicXOffset":-19.2,
 "graphicYOffset":-18.2,
 "graphicWidth":38.4,
 "graphicHeight":38.4,
 "id":"sn_sunny_copy68",
 "strokeLinecap":"round",
 "strokeOpacity":1,
 "fillOpacity":1,
 "pointRadius":0}
)

These markers are easily draggable using the existing
OpenLayers.Feature.Vector dragging tools.

Note that OpenLayers.Feature in and of itself doesn't get you
draggability: just OpenLayers.Feature.*Vector* does. But yes.

This is another GMaps misconception: In GMaps, all overlays are on a
single layer. In OpenLayers, the "layer" you attach features to is
*just* for the features. You will have multiple base layers (Google, Not
Google, Map tiles, whatever) and an *overlay* layer (which can be turned
on and off).

In general, you can even have, for example, all your lines on one layer,
all your points on another.

At the current time, only one layer can be 'selectable' (and therefore
draggable) at a time -- therefore there are technical limitations
blocking this, but that's at least the idea.

> And finally, I don't understand why a Feature has it's own lonlat that
> could be different from the one the Marker has....?

It shouldn't ever be different. Just two different levels of
abstraction: Feature has a lonlat, and you shouldn't need to think about
a marker at that point.

Hope this helps,

No. A ticket is filed for 2.7: http://trac.openlayers.org/ticket/1469

This should have enough description to work with, I believe.

Ticket above should help.

also note that if you preload the images, it should work.

this may or may not be easy to do, but if you look at the
examples/popupMatrix.html example,
you will see that the four images it uses are preloaded (offscreen) in
the body of the html

Historical, really. We had GMarkers working way before we needed lines and
areas in GMap2. But there's no reason now to treat them differently.

Ok, that's kinda the feeling I was getting looking at the code.

Good, I'd already started heading down that road.

Well, then let me ask this. All our markers (draggable or not) currently
can be clicked to open a GMap2 infowindow for details about that marker.

If I split the markers into draggable and non-draggable, and create a
separate layer for each, does that mean only the selected layer will
receive click events?

Ok, so it sounds like what I should do is use a Vector feature w/a Point
geometry and appropriate styling, instead of using a Marker or a base 
Feature w/a Marker.

Yes, this is a huge help, thanks.

Yeah, that is the current state.

You can have two different SelectFeature controls attached to the map;
the problem them is switching between them becomes a deliberate user
action.

You can also collect click events explicitly with a Click Handler, and
on a click, loop through your non-active select layer, and test for
Geometry intersection. This would essentially mimic the way that I would
advise building a more advanced SelectFeature that supported selecting
features from multiple layers.

Yep, that's what I would recommend.

Hi, thanks so much!!!

After Eric, Frederic and Christopher 's support, the map is looking a lot 
better!!!  Thank you all for this great work.

With http://openlayers.org/api/2.6-rc1/OpenLayers.js
the ScaleLine and OverviewMap controls, are still not working; neither with 
http://dev.openlayers.org/nightly/OpenLayers.js

I am using Firefox (with FireFTP) and Konqueror as browsers, and Kompozer for 
html editing, all under OpenSuSE 10.3's Linux distro. Under XP I see the same 
symptoms.

Maybe I should wait until 2.6... However MousePosition and 
addLayers/LayerSwitcher are doing great. Also, the markers are not where they 
should be (in land when they should be on the water) but after zooming in 
they are just right.

It is a lot better. You can see the changes on:
http://www.cmmrleviathan.org/ciencia_GIS.htm

GPSanino

The Overview Map is causing you problems. (I don't really know why.) If
you drop the OverviewMap out, the ScaleLine should work. 

> Maybe I should wait until 2.6... 

That won't help you here.

That probably means that your iconOffset isn't actually what you mean
for it to be. As far as I can tell, the anchor point of the markers
isn't changing, so I think you're just suffering from an iconOffset that
isn't actually what you mean.

Thanks Chaps.

Email preloading works like a dream. It's pretty easy to do for what I'm
doing.

Hi Matt,

I'm currently implementing your suggestions. I'm able to size the 
symbols as a function of the initial zoom level, but I can't figure out 
how to attach an event handler to the endzoom event. How can I add an 
event handler which makes a function call?

http://localhost/thematicmapping/experiments/openlayers/propsymbols.html
(the hover effect still needs some improvements).

Subject: [OpenLayers-Users] How to change style['select'] in OL 2.6
Message-ID: <E1JiBxQ-00064d-00@smtp06.web.de>

Hi,

First, a great compliment to all the developers of OL. And best, only some
easy changes needed to update own applications from 2.5 to 2.6.

But some behaviour I'm used to in 2.5, I could not solve for 2.6.

In OL 2.5 I do this to draw red features and draw select features in yellow:

    OpenLayers.Feature.Vector.style['select']['fillColor']    = 'yellow';
    OpenLayers.Feature.Vector.style['select']['strokeColor']  = 'yellow';

    var layer_style = OpenLayers.Util.extend({},
OpenLayers.Feature.Vector.style['default']);

    style_red = OpenLayers.Util.extend({}, layer_style);
    style_red.strokeColor = "red";
    style_red.fillColor   = "red";

    vector = new OpenLayers.Layer.Vector("Editable Vectors", {style:
style_red});


With OL 2.6 I have no luck. The features will drawn in red, but the selected
features are also in red.

How can I change the default style for selected features in OL 2.6?


With OL 2.6 the SelectFeatureControl allows to edit the vertices. I would
like the previous behaviour. 

Is there a way to disable the edit function for the SelectFeatureControl?


And last. Also a compliment for solving the problem with the flickering of
the Google layers, but is there a reason that OL sticks to only 19
zoomlevels for the Google layer? Google have 22 zoomlevels and especially
for where I come from (Wuppertal), it's possible to get images for
zoomlevels > 19. I use this patch to get all levels:

OpenLayers.Layer.Google.prototype.RESOLUTIONS =
[1.40625,0.703125,0.3515625,0.17578125,0.087890625,0.0439453125,0.0219726562

Hi Arnd,

Thank you for sharing this solution!
It seems to work on: 
http://localhost/thematicmapping/experiments/openlayers/propsymbols2.html

Do you think that this solution will have some performance issues due to 
more "complex" polygons?
The good thing is that no event handling is needed when the user zoom 
the map.

Hi David,

I will consider thematic mapping with WMS at a later stage.

"European Interactive Atlas Explorer" is a good example:
http://karlinapp.ethz.ch/wms_client/

The disadvantage is lack of interactivity on the client.

Hi Bjorn,

It seems that the 200 regular polygons behave as the 200 circles. I have
also thought, that the complex polygons would slow down the application. I
think up to 500 features the performance will be ok.

You can also think about WFS instead of WMS.

Hi Arnd,

Thank you for sharing this solution!
It seems to work on: 
http://localhost/thematicmapping/experiments/openlayers/propsymbols2.html

Do you think that this solution will have some performance issues due to
more "complex" polygons?
The good thing is that no event handling is needed when the user zoom the
map.

Bjorn,

your requirement is covered by the new OpenLayers.StyleMap.

First of all, have a look at the styles-context example 
(http://www.openlayers.org/dev/examples/styles-context.html). The second 
example there (the points in the southern hemisphere) are created with 
an advanced template. The same can be done for your use case.

If I take your original code for the calculation of the size:

feature.style.pointRadius = 3 + (pop * (40 / 1312978855));
feature.style.fillColor = feature.attributes['colour'];

I can create the following template:

var context = {
    getSize: function(feature) {
        return feature.attributes["population"] * someFactor * map.getScale();
    },
    getColour: function(feature) {
        return feature.attributes["colour"];
    }
};
var template = {
    fillOpacity: 0.9
    pointRadius: "${getSize}", // using context.getSize(feature)
    fillColor: "${getColour}"  // using context.getColour(feature)
};

var style = new OpenLayers.Style(template, {context: context});
vectors = new OpenLayers.Layer.Vector("Vector Layer", {
    styleMap: new OpenLayers.StyleMap(style)});


You only have to find an algorithm to derive your pointRadius from 
(using map.getScale() or map.getResolution() and someFactor).

Also, there is no need to set any feature styles in the onload method. 
You're all set with the above definition of the styleMap in the 
constructor for your vector layer.

Regards,
Andreas.

You're right. The solution does not even involve rules.

Well, the wiki page will have to be changed once it is decided how to 
continue with the rules/filters issue.

The solution is in the styles-context.html example. I already posted a 
detailled answer as reply to another posting in this thread.

The simplest way would be

var selectStyle = OpenLayers.Util.applyDefaults({
    fillColor: "yellow",
    strokeColor: "yellow"}, OpenLayers.Feature.Vector.style["select"]);

var selectFeatureControl = OpenLayers.Control.SelectFeature(yourLayer, {
    selectStyle: selectStyle});

Thanks for this detailed explanation Andreas. The style/rule framework
is so rich that it's kinda hard to keep up with all of its features.

In this case, though, there are no rules or filters to worry about; I'm
just not knowledgable to know any better :)

Thanks for the detailed response later in the thread: I'll add that one
to my repitoire of knowledge about styling: I just didn't want to
misdirect in this case (as I would have, had I not waited for you ;)). 

Thanks again,

Papers and Workshops
To: announce@lists.osgeo.org


If you attend just one GIS conference in 2008, make it FOSS4G 2008! It
promises to be the highlight of your year.

The 2008 Free and Open Source Software for Geospatial (FOSS4G)
conference, incorporating GISSA 2008, is on the horizon.

WHERE: Cape Town, South Africa, at the Cape Town International
Convention Centre. Cape Town is one of the Top 5 worldwide tourist and
conference destinations.

WHEN: Monday 29 September to Friday 3 October. Extend your stay with a
holiday in beautiful South Africa and make the trip even more
worthwhile.

Theme: "Open Source Geospatial: An Option for Developing Nations"

FOSS4G is presented annually by the Open Source Geospatial Foundation
(OSGeo) and in 2007 gathered 700 developers and users of open source
geospatial software as well as managers and decision makers from around
the world to discuss new directions, exciting implementations, and
growing business opportunities in the field of open source geospatial
software.

Incorporation of GISSA 2008 this year opens FOSS4G to a wider field of
GIS practitioners and decision makers. GISSA is the GeoInformation
Society of South Africa and we want all players from South Africa to
join their peers from around the world at this international event. Come
and present your work, learn about Open Source GIS and participate in
the FOSS-Proprietary debate.

South Africa's recent adoption of a National Open Source Policy in
Government and the introduction of GIS into our school syllabus this
year make FOSS4G an especially important conference for South Africa and
other countries in a similar position.

Major features include Hands-on Workshops and Labs, Presentations and
Academic Papers, a live Demo Theatre, large exhibition hall, Outreach
activities, Technical visits and a great social programme including a
gala dinner at Moyo in Stellenbosch.

Visit the website http://www.foss4g2008.org to find out more. Register
or submit an Abstract or Workshop Proposal. This year there will be an
Academic Track in addition to non-peer-reviewed presentations, catering
for a wide range of topics.

Autodesk and Google have already come on board as sponsors. If your
organisation is interested in supporting the conference or exhibiting,
please download the Prospectus from the website.

Please circulate this widely.

I'm looking forward to seeing you in Cape Town!

It works.

But i'm not able to set the color of the vertices and the radius. Is there a
way to change these values as well?

And when I move a vertice, the feature will change to red (cleared the
selection?).

And the code works not for the ModifyFeature.Control.


Apart from this. With the SelectFeatureControl I can't toggle the selection
( i have to click outside the feature to unselect), but with the
ModifyFeature.Control it's possible. Shouldn't it be for both the same way?

The simplest way would be

var selectStyle = OpenLayers.Util.applyDefaults({
    fillColor: "yellow",
    strokeColor: "yellow"}, OpenLayers.Feature.Vector.style["select"]);

var selectFeatureControl = OpenLayers.Control.SelectFeature(yourLayer, {
    selectStyle: selectStyle});

Bjorn,

your requirement is covered by the new OpenLayers.StyleMap.

First of all, have a look at the styles-context example
(http://www.openlayers.org/dev/examples/styles-context.html). The second
example there (the points in the southern hemisphere) are created with an
advanced template. The same can be done for your use case.

If I take your original code for the calculation of the size:

feature.style.pointRadius = 3 + (pop * (40 / 1312978855));
feature.style.fillColor = feature.attributes['colour'];

I can create the following template:

var context = {
    getSize: function(feature) {
        return feature.attributes["population"] * someFactor *
map.getScale();
    },
    getColour: function(feature) {
        return feature.attributes["colour"];
    }
};
var template = {
    fillOpacity: 0.9
    pointRadius: "${getSize}", // using context.getSize(feature)
    fillColor: "${getColour}"  // using context.getColour(feature) };

var style = new OpenLayers.Style(template, {context: context}); vectors =
new OpenLayers.Layer.Vector("Vector Layer", {
    styleMap: new OpenLayers.StyleMap(style)});


You only have to find an algorithm to derive your pointRadius from (using
map.getScale() or map.getResolution() and someFactor).

Also, there is no need to set any feature styles in the onload method. 
You're all set with the above definition of the styleMap in the constructor
for your vector layer.

Regards,
Andreas.

This would be the virtualStyle property of Control.ModifyFeature. But 
there is a bug which prevents that from working 
(http://trac.openlayers.org/ticket/1495). This should be fixed soon, 
probably before the final release of OL 2.6.

Andreas.

Thank you!

The circles are now scaling properly on each zoom level:
http://thematicmapping.org/experiments/openlayers/propsymbols_stylemap.html

How can I adjust the hover effect (keep the same size)?

Subject: [OpenLayers-Users] registering a click on a marker
Message-ID: <47F9925D.7080809@alt2is.com>

I am confused about how to register an event on a marker.
I have a marker layer at a coarse resolution, with markers assigned to 
different variables.
I would like to have a click on the marker cause  a zoom in to that 
location, plus a replacement of the makers with a new set of markers 
that show more detail for that location. I am using code like this

        function handleMarkerClickEU(evt) {
        map.setCenter(new OpenLayers.LonLat(13.000000,51.000000), 3);
        var vols_cyball = new OpenLayers.Layer.Markers( 'volunteers 
living in Europe (balloons)');
        var vols_cynumb = new OpenLayers.Layer.Markers( 'volunteers 
living in Europe (numbers)');
        var vols_cytext = new OpenLayers.Layer.Text( "text", {location: 
"../data/volsTextCYEU_utf8.csv"});       
        map.addLayers([vols_cyball, vols_cynumb, vols_cytext]);
        <?php include 'volsBalloonsAndNumbersCYEU_utf8.php';  ?>
       
        map.removeLayer(vols_ctball);
        map.removeLayer(vols_ctnumb);
        }

var markerEU = new OpenLayers.Marker(new 
OpenLayers.LonLat(13.000000,51.000000),icon);
vols_ctball.addMarker( markerEU);
markerEU.events.register("onclick" , markerEU, handleMarkerClickEU);

which doesn't show any errors, but nothing happens.

The event handler worked OK when I registered it to the map, but not 
when I register it to a marker.

Thanks for your help, Tara

Hi, try "click" instead of "onclick" ?

Subject: [OpenLayers-Users] Deactivate Draw-Control after feature added
Message-ID: <47F9D7A8.3030700@kevinkempfer.de>

Hi,

I'm trying to let the user draw a line feature and deactivate the draw 
feature after the feature was added to the map. Here's my code:

var drawControls = {
                 point: new OpenLayers.Control.DrawFeature(vectors,
                             OpenLayers.Handler.Point),
                 line: new OpenLayers.Control.DrawFeature(vectors,
 
OpenLayers.Handler.Path,{featureAdded: 						toggle }
			),
                 rectangle: new OpenLayers.Control.DrawFeature(vectors,
                             OpenLayers.Handler.Box),
                 select: new OpenLayers.Control.SelectFeature(vectors),
             };

             for(var key in drawControls) {
                 map.addControl(drawControls[key]);
             }


function toggle(feature){
	var linecontrol = drawControls['line'];
	linecontrol.deactivate();
}

I get an error as soon as the control gets deactivated:
this.point has no properties
-> this.point.destroy();

Here's the trace from FireBug:
destroyFeature()Point.js (line 128)
destroyFeature()Path.js (line 81)
finalize()Point.js (line 139)
dblclick(dblclick clientX=0, clientY=0)Path.js (line 240)
triggerEvent("dblclick", dblclick clientX=0, clientY=0)Events.js (line 612)
handleBrowserEvent(dblclick clientX=0, clientY=0)Events.js (line 640)
bindAsEventListener(dblclick clientX=0, clientY=0)

Looks like the control gets deactivated too early in the feature-adding 
process. Is there any advice on how to deactivate a draw control after 
drawing a feature?

Thanks,

Kevin

Message-ID: <BAY102-W49E254C07A5AB7E9F31707CCF30@phx.gbl>


Hello,

I have a stupid error when trying to delete a vector feature. I've updated OpenLayers from 2.5 to 2.6 (latest from trunk) and when trying to delete a feature I have the corners of the polygon that stay on the map.

I've added a control like this :

// Delete feature
var deleteTool = new OpenLayers.Control.SelectFeature(layer_vector,
{
           onSelect:deleteFeature,
 });

And the called method is like this :
function deleteFeature(feature) {
    getEditableLayer().removeFeatures(feature);
}


The problem seems to be that when getting the vector layer (thru the getLayersByName() method) the feature is set to "modification mode".

I've tried to look around for the "renderIntent" property of the selectfeature control but I don't know the clean way to use it.

Thanks,

Benoit Pesty

Message-ID: <4ca668230804070903y56d621e6o8c4005dfc6b5e912@mail.gmail.com>

Hi all,

I have generated TMS pictures with the gdal2tiles.py tool from a
PNG+WLD. I got a tilemapresource.xml and PNG named x/y/z.png with
x<5,y<10 and z<10. I placed them on my webserver and added a TMS layer
to my OL map.

But I can see with FireBug that OL is looking for pictures like
0/1258/973.png that I don't have. I guess that OL doesn't read the
tilemapresource.xml and I have to tell him the origin and bounding box
of the tiles. I tried to set the maxExtent and tilesOrigin attributes
of the TMS layer, but it doesn't help.

Could you tell me what I should do? I presume it's obvious.
Thanks,
Gerald

Hello,

On the OpenLayers home page (http://openlayers.org/) there is a link to the
latest release (http://www.openlayers.org/api/OpenLayers.js) which is the
2.5 release.  At the top of the same page it has a link titled "Class
Documentation" which leads to
"http://dev.openlayers.org/apidocs/files/OpenLayers-js.html".  

It is clear to me now that the class documentation is not the 2.5 API
documentation, because I continue to get errors when I use some of the
properties/methods listed in the API when using the 2.5 JS file.  This is
extremely frustrating because now I do not know what my API options are.

Is there a 2.5 API documentation page somewhere?

Thanks for your help - Peter

Subject: [OpenLayers-Users] How to obtain reference to map layer in 2.5????
Message-ID: <16545652.post@talk.nabble.com>


Hello,

I am using OpenLayers 2.5.  Our situation is that we are getting a handle to
the map after someone else has loaded some WMS map layers.  So, by the time
I can do anything with the OpenLayers map, another group has added 10 or 11
map layers through calls like:

var ol_wms = new OpenLayers.Layer.WMS( "OpenLayers WMS", 
                "http://labs.metacarta.com/wms/vmap0?", {layers: 'basic'},
                options); 

I want to get a handle to a particular layer and I think I have to use the
OpenLayers API to get the layer.  For example, the 2.5 API has a
map.getLayer([layer_id]); and then a map.setBaseLayer(OpenLayers.Layer);
 
My question is that you have to have the layer ID as the argument for the
getLayer() function.  Since I did not load any of those layers, I don't know
how I would get the ID for the layer I am interested in.  There is no
generic function which returns an array of all the layers to which I could
just cycle through and check each layers name, for example.  Version 2.6 has
more functions to obtain layer data but we must use 2.5 for the time being.  

Any thoughts how I can programmatically go through the layers?

Thanks - Peter

I would imagine that you can use something like:

for (var i=0; i<map.layers.length; i++) {
     var layer = map.layers[i];
     //do something with the layer?
}

Dear Developers,

I'm considering using the following code in an production environment, but I
read in this thread, that this shouldn't be used in production environments,
because isn't stable enought.

I've researched about measure tools, and I saw many differents attempts of
implementations, but this seems to be the most up-to-date one, as far as I
can see.

What's the problem in using this is a production environment? Does anybody
has another better solution to point me out?

regards,

Pedro Simonetti.

PS: Congratulations for this amazing project!

I am trying to get the following simple map to work so that the user can 
zoom in to the maximum level available for each layer, and when 
switching between the two base layers there are not any jumps in the 
zoom level. I see several posts in the forum about this issue, but none 
seem to have the complete solution. This would make a great example map 
to add to your list, if someone could help get this working.
Thanks, Tara

Subject: [OpenLayers-Users] 2.6 problem with vectors in IE
Message-ID: <JCEJKDEMIHKMMHKNOHNNCENMEHAA.brad@cubewerx.com.au>

List,

I have been using 2.6 because of a new feature I wanted. However, I have
found that in IE when creating vectors (i.e. drawing of the edges of a
mouse-Shift selection box in my case) they are always drawn in the top left
corner of the map Div. The vectors look correct just located in wrong place.
And when you zoom out it stays in the left corner i.e. moves to the left top
corner. Aspect ratio and dimensions of box are correct and the coordinates
used were fine for centering and zooming over the collection. Just the box
(or vectors) are in the wrong place. Works OK when I go back to 2.5 and
works OK in FF.

Just thought you might like to know as this took me awhile to twig what was
happening.

Okay, so what should we do? What would be more helpful to you?

My standard assumption is that anyone using OpenLayers seriously is
going to download the code. With the code ships a full set of
documentation in the 'doc' directory. If you read those, they are teh
docs for the version you downloaded. 

Apparently this isn't the case. 

Note that before a couple months ago, we didn't *have* versioned docs:
this is an improvement in our process, which is constantly evolving.
Although I understand that you are frustrated, there is only so much
developer time that can be invested into things like this without
negatively impacting active development of the project: doubly so
because, at the moment, I'm one of two people with access to change
things on the server.

Direction on exactly what you think would be more useful than the
current situation would be helpful: What text you would change, what
link you would change, etc. This is much more helpful than claiming "You
must do better!": to be honest, a fair amount, if not all, of the code
for the website is in svn, so if you have a problem that you think you
can change, the answer is the same as always:
  
  "Patches welcome."

Pretty sure this is #1477, which is fixed in trunk (and will soon be
released in RC2): can you try pointing to
http://dev.openlayers.org/nightly/OpenLayers.js and see if it's fixed?

Paul,

Thanks for the reply.  That worked fine but my frustration with some of this is that the API (http://dev.openlayers.org/releases/OpenLayers-2.5/doc/apidocs/files/OpenLayers/Map-js.html) does not list a "layers" property for the map object.  How is someone suppose to know that it is available to use?

Thanks for your insight - Peter

The page works perfectly if opened through the browser but not using the OL

How is someone suppose to know that it is available to use?

Peter,

In general, we take a very conservative position as to what is an API
property vs. what is not an API Property. The reason for this is that in
general, we have no specific ideas on how we might need to change the
code in the future to support a particular use case.

As an example:

In OpenLayers 2.5, we had controls which had multiple '.fooHandler'
properties. Things like 'zoomWheelHandler', etc. In 2.6, in order to
protect ourselves against memory leaks, we moved these handlers into a
'.handlers' object, with multiple keys ('foo', 'bar', 'baz'), so that
they could be automatically destroyed by the base control class, thus
ensuring that their DOM elements were properly decoupled from the
Javascript.

If we had made the .fooHandler property an API property, we wouldn't
have been able to make this change, and would have had to make a much
more significant change which was more fragile.

This is the case despite the fact that using handlers as an API property
is absolutely useful -- I use it in some of my own applications.

The lack of something being an API property does not mean "Absolutely do
not use it." It means "This may change in a future release of
OpenLayers: you should use it with caution."

For that reason, we include a full set of documentation of the *other* 
properties on objects:
http://dev.openlayers.org/releases/OpenLayers-2.5/doc/devdocs/files/OpenLayers/Map-js.html#OpenLayers.Map.layers
, in this particular case. 

If you are not comfortable with the fact that something is *not* an API
property, then the right thing to do is to make a proposal to the dev
list that it be made an API property.

In the case of map.layers, I have no problem making it an API property
upon being asked: the biggest reason we don't make things API properties
is so that people *will* ask, and we'll know what they're doing with it.

By doing this, for example, we were able to determine that what people
actually typically want is not direct access to the layers object
itself, but instead the ability to, for example, fetch a list of layers
by name. So OpenLayers 2.6 -- while keeping map.layers out of the API --
adds an OpenLayers.Map.getLayersBy() function, which allows for you to
get a layer by any property it has: for example:

  map.getLayersBy("name", "My WMS Layer");

Additionally, since getLayersByName seems a common use case, we have a
wrapper:

  map.getLayersByName("My WMS Layer");

Now, if we find out in the future we need to split layers into
.baseLayers and .overlayLayers for some reason, we can do so -- and we
haven't broken the API. Additionally, we've added functionality which is
common to more than one application, and I believe we've met most of the
needs that an application would have to loop through the layers
property, without exposing ourselves to possible holes in backwards
compatibility. 

This conservatism has served us well through many releases, and although
I understand that it may make life slightly more difficult, we do our
best to meet both sets of needs: those who need a very stable API
between versions can use the API properties, those who are willing to
take a bit more risk and do testing before upgrades to ensure their
application still works can do so, and the developers can make the
explicit decision to include things in the API as they become neccesary,
rather than simply by guessing what makes sense ahead of time.

Hopefully this helps to explain our policy such that it is reasonably
understandable without causing too much difficulty.

Best Regards,

The reason why you were advised not to use this code in a production
environnement is probably because it comes from a sandbox.
As you probably already know, sandboxes are there to let developers
play with OpenLayers code and new features.

That said, the considered code may still need work, or may be based on
an old version of OpenLayers. It will therefore be somewhat difficult
to upgrade to a new OpenLayers version (2.6 when it will be out for
example) when you'll need to.
I think that there's no other constraints. And you're free to use this
code either way.
You just need to be aware of what precautions you'll have to follow.

For this particular feature (measuring tools), it would have been
easier if they were provided as an OpenLayers addin. But I'm pretty
sure that addins came after this code was initially written.

Regards,
Pierre

Are you using a ProxyHost? the proxy.cgi that OpenLayers ships with
doesn't do anything smart with auth.

The gdal2tiles.py tools generates a sample openlayers.html which works
perfectly with the script http://www.openlayers.org/api/OpenLayers.js.
As soon as I replace it by the 2.6rc1 release, I get an error
"this.projection.getUnits is not a function" in the setMap function of
the Layer class.

I think it comes from the way maxExtent and projection options are
initialized in the example:
       var options = {
            controls: [],
            maxExtent: new OpenLayers.Bounds(0, 0, 2770, 2270),
            maxResolution: 16,
            numZoomLevels: 5,
            units: 'pixels',
            projection: ""
        };
        map = new OpenLayers.Map("map", options);
        map.addControl(new OpenLayers.Control.PanZoomBar());
        map.addControl(new OpenLayers.Control.MouseDefaults());
        map.addControl(new OpenLayers.Control.KeyboardDefaults());
        // OpenLayers 2.5 TMS driver
        layer = new OpenLayers.Layer.TMS( "TMS",
                "", {layername: '.', serviceVersion: '.', type:'png'} );
        map.addLayer(layer);
        map.zoomTo(3);

Did someone used this gdal2tiles.py tool?
How can I mix this TMS+strange SRS with a classical WMS layer+EPSG:4326?

Thanks for your help,

Yeah, if you drop "projection":"" from that, it should work okay.

Is your original image a worldwide map in EPSG:4326? If not, it's likely
that the answer is "You can't.", because OpenLayers doesn't support TMS
with different maxExtent and so on (though there is a Summer of Code
proposal to improve this.)

No, the page is on the same server but protected using windows

Thanks for the explanation, I was looking for a solution to improve
performance. I'll have to keep my WMS layer and search for
improvements on the GeoServer side.

Done! Thanks!! 


Using firebug I saw the page was loading but I had done an error passing the
name of the functions for success and failure management. Everything works
fine now!?

Christopher,

Thanks for info.  I definitely see where you are coming from and now that you have supplied me with a link to some docs that list non-API items, I am good.  At least now I can see what other things are available.

Thanks - Peter

That worked fine but my frustration with some of this is that the API (http://dev.openlayers.org/releases/OpenLayers-2.5/doc/apidocs/files/OpenLayers/Map-js.html) does not list a "layers" property for the map object.

Message-ID: <013601c8998d$af421080$0dc63180$@gadenz@jrc.it>

Hi all again! 

 

I am experiencing some problems using multiple layer having attached popup
to the onSelectFeature method.

 

In fact I have a map showing  georss feeds on top of a google layer and I
attached a popup to the georss elements using the onSelectFeature method. 

Then I create the same structure for another layer that is supposed to be
the container for markers returned by a dynamyc a geocoding process. In
other words I ask the google geocoder to locate an address and then I plot a
marker into that layer in the returned position.

 

I have two problems:

 

- after the geocoder provies a couple of coordinate the  setCenter function
is invoked to recenter the map and a new feature is added to the geocoded
points container but the other georss layer does not reposition

- clicking on the different features only the ones in the top layer open a
popup. To access the features in the layer below the upper lavel has to be
switched off.

 

Anybody is aving the same?

 

Simone

I took a quick look at your problem by trying to load the ViaMichelin
API beside OpenLayers (in lite.html example).
An error is raised in Events.js where OpenLayers tries to call push()
on an array.

But it seems that the ViaMichelin API modifies/extends the Array
prototype to provide a new "ci" function (bad! bad!).

This is a quick investigation and I have no workaround at the moment.

Pierre

This is a known behavior. There is no simple workaround at this time.
(SelectFeature only works for the top layer.)

If there is a documentation link on the OL site, people will use it,  
and very possibly then ignore downloaded docs.  I assumed also that  
the docs link on the site was for v2.5, though I didn't run into any  
problems, maybe because I'm doing simple stuff so far.

There is also the bonus online of the search feature.  At least for  
the unversioned link (v2.5 link doesn't have the search).

As Barend says, the problem I see with any of the docs is that they  
don't mention what version they are for.  Fine if you look at the  
downloaded docs, but not when viewed on the OL site.  I think that's  
fairly explicit about what needs changing: add visible version text to  
the docs, and shouldn't take much time to do.  How about in the upper- 
left title text, which appears on all pages:

"
OpenLayers
JavaScript Mapping Library
version: [full version goes here]
"


Note: I couldn't find a direct link on the OL site to the v2.5 docs  
you mentioned, or any other "versioned" docs.

Thanks Pierre,

Actually, I'm using it in 2.6 RC1, and it's working well. And since this
feature is provided by a single external js file
(Openlayers/Control/Measure.js), I think that will be easy to put this as an
openlayers addin. There's no need to change other openlayers files, except
the "openlayers.js", where you need to add a single line to make this
feature loaded, like:

        var jsfiles = new Array(
            ...
            "OpenLayers/Control/Measure.js",
            ...

The only problem I found is that the measure tool is kinda slow in IE, but I
think this is a problem of IE rendering vectors. But, I'm fine, I don't see
this as a real problem.

I saw many people asking about this feature here at the forum, so I think
that will be great see this tool as an addin of the final 2.6.

regards,

Pedro Simonetti.

Hello

I understand that most experts are saying it is far better not to load
images in a database but rather to serve them from a file based system.
There are two commercial products that I know of ER Mapper - Image Web
Server and ArcGIS Image Server what OSS products provide comparable
functionalities.  If these are available are there any bench mark studies
done and also I would like to integrate such products with ArcGIS Server.

Yes this fixed the problem - you guys always seem to be one step ahead!
Thanks for that.

Should I download the latest version of 2.6 to get this fix?

Pretty sure this is #1477, which is fixed in trunk (and will soon be
released in RC2): can you try pointing to
http://dev.openlayers.org/nightly/OpenLayers.js and see if it's fixed?

Subject: [OpenLayers-Users]  Strange behaviour after panning
Message-ID: <16575710.post@talk.nabble.com>


Dear developers,

I'm trying to develop a query feature in my project, but I'm getting a
strange behaviour. I'm using 2 kaMap layers, one raster satellite image, and
one vector shape file.

Please visit:

http://189.52.176.118:8080/teste/?zoom=5&lat=7756661.87151&lon=364887.48481&layers=BT

Then click in the map inside the polygon named "Jardim da Penha". Note that
the query will result the right response, showing the text "Jardim da Penha"
in the lower right corner of the screen.

But, then, click and drag, moving the mouse to the right. And then click on
another polygon, for example, the named "Itarare". The result will be wrong.
Here I got "Jardim da Penha", but clicking in other areas you will got
different results.

It seems when you pan the map, it looses the correct coordinates. It's like
the "map.getLonLatFromLayerPx" still thinking it is in the same coordinates
that before panning.

What I'm doing wrong??

I have limited english skills, so if my message isn't clear enought, please
ask me about specific details.

I'm using the 2.6 RC1. I'm making the query through PHP mapscript.

NOTE: The images i'm using are very big, and my development server is kinda
slow. So, if the images don't load properly, please press F5, and they
should appear.

regards,

Pedro.

Hi John,

I would imagine that you could use GDAL with

John,

If you just want a hillshading effect, GoogleMaps has an optional map called
'type: G_PHYSICAL_MAP' - I'm not sure how extensive this is across the
globe.

This looks good in a hilly area but is not very useful as a DEM with
geometry.

Hope that helps.

Cheers,

Brad Spencer

After some investigations, I found how to fix it.

I've changed the piece of the code where it calculates the coordinates,
from:

  var lonlat = map.getLonLatFromLayerPx(evt.xy);

To:

  var lonlat = map.getLonLatFromViewPortPx(evt.xy);

Now it works fine. 

I'm just wondering, what's the difference of "getLonLatFromLayerPx", and
"getLonLatFromViewPortPx"? I've looked at the docs but I still don't get it.
At first glance, I thought that these methods were similars.

my best regards,

Pedro Simonetti.

I have two layers that when I switch between them the performance is
so bad that there is a noticeable delay.  How would I implement an
hourglass cursor to indicate to the user that the application is
working and then put the cursor back to normal when the layer is
loaded.

I'm looking for an already operating tool that exposes the actual
elevation data -- maybe as a third dimension in the mouse coordinate
control.

Perhaps I should ask on geowanking.

I am also interested in the answer to this question. I have some users 
on dial-up so they have a delay for just about everything.
I have used the basic DOM commands
document.body.style.cursor = "wait";
document.body.style.cursor = "default";

for the initial map load, but don't know how to do this for a layer switch.

Hi Linda,

you could have a look at the LoadingPanel Control. Something similar could
be done to change the map cursor.

See:
http://trac.openlayers.org/ticket/102

and:
http://trac.openlayers.org/browser/sandbox/bartvde/loadingpanel/lib/OpenLayers/Control/LoadingPanel.js

In maximizeControl you could set the busy mouse cursor on the map div, and
in minimizeControl change the cursor back.

example:
http://dev.openlayers.org/sandbox/bartvde/loadingpanel/examples/loadingpanel.html

Best regards,
Bart

Where does the discussion for the OpenLayers Documentation Team occur? I 
don't see a Documentation Mailing List on the website.

PS. I have changed the links on the wiki documentation page to point 
towards the docs (api and dev) for 2.5.  If the home page documentation 
links (two of them) are changed to point to this wiki page, then this 
would be the only one that needs to be updated when a new release comes 
out, and then all neophyte OpenLayers users would be pointed to the 
stable docs, even if they don't download the code.  Sure wish I had 
known about these links during the last year while I tried to understand 
OpenLayers!

Actually, you don't really need to add a new line in your OpenLayers.js file.
Adding a new link to your Measure.js would do the job.
<script src="path/to/your/Measure.js"></script>

That way you don't modified anything in OpenLayers.

Is this the same reason causing the lower georss layer to not reposition the
markers when the setCenter method is invoked?

This is a known behavior. There is no simple workaround at this time.
(SelectFeature only works for the top layer.)

Discussion about documentation takes place on any of the channels that
we have, dev or users mailing list and/or the #openlayers IRC channel
at Freenode.
Because docs are written mainly by devs, it hasn't been necessary a
specific mailing list for documentators. I'm sure that if it's needed,
it will be done, but I don't feel that.

I modified it so it includes both now, the latest stable (2.5) and the
trunk version.
The problem now is that every time a release is done, we should change
it. I hope we can improve this process soon.

Thanks for your suggestions.

Dear all,

 

I would like to modify the style of a feature to a dashed border style.
I try the following code, but it doesn't work. Can you please help me to
solve this problem?

 

Var my_style = {

            strokeColor : <blue >,

            strokeWidth : 1,

            fillColor : < blue >,

            fillOpacity : 0.2,

            borderStyle : < dashed > 

}

 

...

 

feature.style = my_style

 

To complete my question: is it possible to have a filling lined
rendering?

 

Thanks,

Julien

Unfortunately, I'm pretty sure that this is something OpenLayers will
never address.
The main reason is that OpenLayers vector renderers rely on SVG for
Firefox/Safari browsers and VML for InternetExplorer.
I had a look into it a while ago, and, as far as I know, none of those
browsers rendering engine support border styles (pattern).

As for Firefox, patterns are supported by SVG but Firefox doesn't
implement the patterns.

Subject: [OpenLayers-Users] parallel loading of tiles from same url
Message-ID: <563584839@web.de>

hi list,

i have the following problem:

i want to use the openlayers to display 2 wms layers, one as a baselayer and another one as a (semitransparent) overlay. during testing i noticed that, if i use different wms urls to load the wms images there is no problem with parallel loading of the tiles. but if both wms layers come from the same wms url the api begins to load *all* tiles of the baselayer and only after it has finished with loading all of them it starts loading the tiles for the overlay, which makes loading the map slower.

as i am not a too deep insider in the api code i am not sure where to adapt this.

i appreciate any advices. thanks in advance,

stefan

Well, I needed an excuse to play with the Control.Hover, which is the
basis for http://wardrobe.dhs.org/jrf/index.html.  The code is rather
crude, but it works on Debian and FF (no performance features like
multi-urls or TC so the server might be slow ).

No. I actually have no idea why that would happen: It makes no sense to

The answer is actually: "THey're the same insofar as you shouldn't need
to use either one of them" :)

Both of these are really designed to be internal methods: I've just
changed their definition from APIMethod to Method. The one you *shoul*
be using is the more nicely named getLonLatFromPixel: this hides the
fact that you have to worry about any of this stuff.

In reality, "FromLayerPx" is designed to work in the pixels of the
layer: the pixels of the layer are *not* shifted when you drag, but are
instead kept the same until you zoom (only the map container is shifted
when you drag). End result is that you'll be off until you zoom, if you 
use the FromLayerPx.

In any case: We providedd getLonLatFromPixel as the main 'API' property
so that people wouldn't have to use a funky-named property: it's a
wrapper around getLonLatFromViewPortPx.

Awesome :) Suggestion: use untiled (and transitionEffect: 'resize') to
give it a shorter loading time for zooms/pans/etc.

You know what the doctor says:
 
  If it hurts when you do that, don't do it!

The solution you had -- of loading from a different URL -- is the
recommended way to solve this problem. The only thing that matters is
the domain name: You can set up multiple DNS aliases pointing to the
same system to achieve the speed up. (Like tile.example.com,
overlay.example.com.)

In this way, you can use the same server, but load things in parallel.

I highly recommend this over trying to change the code: switching back
and forth between layers in an effort to load tiles would seriously
complicate things and make your life more difficult, and it would be
somewhat unlikely that we would integrate such a change into OpenLayers
unless it was really nicely done.

Message-ID: <9C37154DC7C8074FBC34214363755B7C1EB47D@ITB-SVR-01.itbeyond.local>

Hi,

 

I have been working today on FramedCloud and have noticed that is works perfectly in IE7 and not in FF2. It appears that when text wraps FF does not resize the box to the correct size. In fact even when it does not have test wrap the bottom line of text if FF2 is chopped off.

 

I have some running examples published at here:

 

http://www.exploroz.com/Directory/Categories/Campers_Trailers.aspx?kw=

 

The OL code is ? the way down. A copy of the registerPopup script is as follows 

function registerPopUp() {

      popup = new OpenLayers.Popup.FramedCloud("ppnt_place", PlacePos, new OpenLayers.Size(200,200), '<h4>Camper Trailers WA</h4>Unit 21 No.8 Booth Place, Balcatta, WA, 6021<br /><a class="lba" href="/Directory/Customer/515.asp">View the full business details</a><br /><a class="lba" href="/Places/Directions.aspx?to=Unit+21+No.8+Booth+Place%2c+Balcatta%2c+WA">Get Driving Directions</a>', null, true, onPopupClose);

      popup.maxSize=new OpenLayers.Size(200,200);

      ppnt.map.addPopup(popup);

}

 

This site is using nightly build however I have also tested in the latest trunk 6826 and the same issue with FF2 is showing.

Hi all,

I am using the library "<script  src="
http://www.openlayers.org/dev/lib/OpenLayers.js"></script>"

but I have seen this post and I thought that is really a good idea to put a
loading panel but when I had the line:

map.addControl( new OpenLayers.Control.LoadingPanel({minSize: new
OpenLayers.Size(600, 600)}) );

the map don't appear!!!!!!

Is it because of the openlayers version I am using?

Thanks

Carlos

Yes, it's not in the standard library, I am hoping it can be an addin soon.
See also the Wiki:

http://trac.openlayers.org/wiki/Addins/LoadingPanel

You can add the following in a <script> tag after the OpenLayers.js <script>
tag:

http://dev.openlayers.org/sandbox/bartvde/loadingpanel/lib/OpenLayers/Control/LoadingPanel.js

Or build your own OpenLayers.js. See also the Wiki page for details. You
also need to use a bit of css to get the background-image. It's described in
the Wiki page.

Best regards,
Bart

Because of the way that OpenLayers determines popup size, it can not
take into account when aspects of the content have a margin set on them.
your <h4> has a margin of 6px on the bottom and 4px on the top. If you
override this:

.olFramedCloudPopupContent h4 {
    margin-bottom:0px;
    margin-top:0px;
}

*after* your Style170108.css (or after the h4 definition in that file)
then it should resolve the issue. (At least, it does for me.)

I don't think you want to do this: how can you be sure this will be big
enough? In this case, it looks like it might not be...

Cool Bill.  If you want pretty hillshade, you can use the USGS WMS

http://gisdata.usgs.gov/wmsconnector/com.esri.wms.Esrimap?ServiceName=USGS_EDC_Elev_NED_3

layers: "HR-NED.IMAGE"

See the layer-opacity.html example for use.

Subject: [OpenLayers-Users] Switching from OL 2.5 to OL 2.6 RC1 Popups
Message-ID: <F2CE622EE27B28478746251A0ED3F0C30408B785@ct11exm65.ds.mot.com>

I have an application that I've developed using OL 2.5 which displays
popups associated with markers, using this sort of approach:
 
var popup = new OpenLayers.Popup (popupName, popupLonLat, popupSize,
popupContent, false);
popup.setBorder ("1px solid");
popup.setBackgroundColor (colorCode[nextColor]); // colorCode is an
array of color strings
popup.setOpacity (1);
popup.hide ();
// Set mouseover and mouseout event handlers, etc.
 
I want to upgrade to 2.6 to pick up bug fixes and to take advantage of
the autoSize feature of the new popup boxes.
 
I tried pointing my application at the OL 2.6 RC1 code to see if it
would work without modification, but it doesn't. My popup boxes are
positioned correctly at the upper left, but their sizes are huge -
extending all the way down and right to the edge of my map. Also, none
of them are hidden nor respond to the mouseover/mouseout events.
 
Either I'm doing something wrong with the way I've created popups in 2.5
or something has changed in 2.6.
 
I assumed that there would be a popup.setAutoSize() method that I could
add to the above code snippet, but there doesn't seem to be one in the
current trunk. I also didn't see an options argument in the initialize()
function. But I did see an example that shows how to create a new popup
class and add an autoSize value at that point, along with using the
feature.createPopup() method, neither of which I'm doing with the 2.5
code - is that the right way to go about doing it?
 
What exactly is the proper method for constructing a popup and setting
the autoSize param in OL 2.6?
 
Thanks ...

Thanks Christopher,

I did as you suggested and it still is not 100%. I did the h4 override
and even took the h4 out and used plain text however when the title
(first line) and address (second line) is long causing wrapping it still
has the last line outside the popup. I have hard coded the program to
show a long address and long title which highlights the problem - this
hard code has also removed the h4 tags. Use FF to visit
http://www.exploroz.com/Directory/Categories/Campers_Trailers.aspx and
you will see it still happens. In fact IE appends a heap of white space
at the end in this example and FF drops off about 1.2 lines. 

The reason behind the popup.maxSize=new OpenLayers.Size(200,200); was an
effort to try to get the max width of the popup down so that after auto
pan it would be out of the way of the PanZoom control. I thought and
maybe incorrectly that if the box wanted to be larger it would auto have
scroll set to auto and thus would provide scroll bars. I have not looked
into the code to see how you are build the element as yet. So if the
maxSize is not the way to go is there a way to get the popup to index
over the PanZoom control? This will only happen on small maps or popups
with a large amount of content, it would be a nice feature as having the
popup half behind the PanZoom seems incorrect! The example posted above
will show the issue in all browsers.

One of my wishes is to be able to run a map in say 300px width and be
able to display all locations from the current page of business
addresses on one map. Similar to the Google search results map which has
the markers for the matching businesses, the example I have shown is
basically the start of this interface using only one specific business.

Hi,

I'm having a problem with hover styles using OpenLayers 2.6-rc1:
http://www.thematicmapping.org/experiments/openlayers/propsymbols.html

When you hover on of the circles the size is not preserved.
Is there a way to define the "default" and "select" styles to be the same?

In 2.6-rc2, this is fixed.

In 2.6-rc1, you can do:

StyleMap({'default': style, 'select': style});

If you want to only change (for example) the color, and not the size,
you can do (in either version):

StyleMap({'default': style, 'select': {strokeColor: '#0000ff'}});

Unfortunately, I'm pretty sure that this is something OpenLayers will
never address.
The main reason is that OpenLayers vector renderers rely on SVG for
Firefox/Safari browsers and VML for InternetExplorer.
I had a look into it a while ago, and, as far as I know, none of those
browsers rendering engine support border styles (pattern).

As for Firefox, patterns are supported by SVG but Firefox doesn't
implement the patterns.

Message-ID: <e666bc580804090951w269a7555j96e9052b3132e13f@mail.gmail.com>

Hi all,

sorry if it is a stupid question.
But unfortunately I can't install mapserver because the IT department don't
allow.
So the solution I have found is make the query to the database and write a
GML file. After that I pass the URL of the file to OpenLayers.
But I thought, maybe instead of writing the GML file I can have a webservice
and tell OpenLayers to receive the layer from the webservice, this way it
would be faster.
I understand that in a normal situation openlayers would use mapserver or
geoserver instead of calling a webservice.

Has anyone made this before?

Thanks

Carlos

Huh ?  stroke patterns are supported in both SVG and Firefox(2.0.12 
anyway).   Now a single stroke cannot have both solid fill and pattern 
border however you can make a rectangle (or polygon, ellipse, ....) that 
does have a solid fill and a stroke border that is dashed or whatever.   
You can always test something in Inkscape to see how the SVG is rendered.

Is it possible in OL to turn off the BaseLayer? In other words I'd like all my layers to be overlays. Looking at it another way, this would allow me to turn off all layers and just have a blank map. I'd also like to have the "Base Layer" portion of the LayerSwitcher disappear if all my layers are Overlays.

Good. I think this will help other users looking for some info about this in
the documentation.


In any case: We providedd getLonLatFromPixel as the main 'API' property

Just a suggestion. Considering that the "getLonLatFromPixel " is a
wrapper around "getLonLatFromViewPortPx", why not renaming it as
"getLonLatFromPixel", and use this in the rest of the library?

As JavaScript is a interpreted language, all function calls has a cost,
and because of this, is not recommended to use wrappers and getters
since they will just call another function, with a higher performance cost.

But, of course, changing this will require a refactoring and many files,
so one have to analyze well the benefits of making such a change,
before starting the refactoring.

Thanks for the helpfull answer!


my best regards,

Pedro Simonetti.

The biggest reason is the same reason we maintain a difference between
getPixelFromLonLat and its underlying function call: in that case, we
(just today) changed the underlying method to not round numbers, but we
can change the API wrapper so that it continues to behave the same, with
no affect on existing applications. If, for example, we wanted to change
the library in the future so that getLonLatFromPixel could, as an
option, transform from the map projection to an actual lon/lat, we could
do this in tis function without affecting the rest of the library.

This performance cost is not important in the big sheme of things. A
single DOM reflow can be hundreds of times more expensive than a
function call. There is no real reason to change this from the way it
currently is.

Nope.

you can use displayInLayerSwitcher as a layer option to turn off the
display of the base layer, and set a non-visible baselayer (like an
instance of the OpenLayers.Layer class) as the baselayer of your map for
a similar effect though.

Yeah, you're right. Such change would require a lot of work, and the
befenits would be almost imperceptible, since the bottleneck of
performance in web applications is more related to DOM operations,
as you stated. So, looking more carefully to it, I also think that it
wouldn't worth doing this.

But, anyway, I was just sharing my thoughts with you developers.

Thanks for your considerations.

Dear Developers,

I'm doing some investigation about the OL's KeyboardDefaults Control. I've
notice that this control isn't working in both IE and Opera, as it was
stated here in this thread and in another one:
http://www.nabble.com/Opera-and-KeyboardDefaults-tt12141147.html#a12141147

I've checked the tickets for this issue:
http://trac.openlayers.org/ticket/864
http://trac.openlayers.org/ticket/1108

There, someone suggest altering the "window" to "document", in two places in
the "KeyboardDefaults.js" file. And there was a comment suggesting to change
the event handled to "onkeypress" to "onkeydown", considering the problems
with "onkeypress" events in IE, as PPK demonstrates at: 
http://www.quirksmode.org/js/keys.html

I've tested changing from "window" to "document", as the ticket suggets. And
I've changed also the "onkeypress" event to "onkeydown" in
"Handler/Keyboard.js" file.

This makes IE and Opera catch the keyboard events, but there's another
problem. It seems IE catch the "onkeydown" event twice with the "+" and "-"
keys used to zoom (I'm using IE6). And there's another problem with Opera.
In Opera, the "+" and "-" keys are used to increase the zoom of the page (it
changes both font and image sizes). So, pressing the "+" and "-" keys to
zoom in a map will also zoom the intire document.

I've noted that changing the event to "onkeyup" seems to fix the problem in
IE. But the Opera still has the problem with the "+" and "-" keys. I think
the solution will be canceling the event propagation. Does the OL has any
function to cancel event propagations? I don't know if Prototype has this
feature.

There's a cross-browser solution from Dean Edwards:
http://dean.edwards.name/weblog/2005/10/add-event2/

Anyway, I'm seding the patch for the modification of
"Control/KeyboardDefaults.js" and "Handler/Keyboard.js" if there's anyone
interested in investigate this issue. The patch were created over 2.6-RC2's
root.

regards,

Pedro Simonetti.

Message-ID: <6e9b30fb0804092313v634fa3cenfd5c9bdf2bd942b5@mail.gmail.com>

I have several vector layers that have line strings on them.  In IE
when I zoom to higher zoom levels (16,17,18) the lines disappear.
They are fine in firefox and I can see the lines at all zoom levels.
Does anybody have an idea why this is only happening on IE?

You probably can. Just curious: your IT dep doesn't allow you to
install MapServer so why would it allow you to install your own web
service?

MapServer and GeoServer are Web Service providers.

 Hello dear sir,
    When I use TMS to deploy images,I have a problem. I know I can use "'maxExtent': bounds,resolutions:[0.000534956337608418,0.000634956337608418]" to make the TMS layer image restricted to a specific bounds. And I also add makers to the map. But when I zoom in the map,the position of the markers was changed. Do you know what is the matter?How to avoid its changing?Thank you!

Subject: [OpenLayers-Users] Avoid world repeat with a Google map layer
Message-ID: <20080410112551.5e712260@dlib-skye.ed.ac.uk>

Hello,

I am trying to display a map, with a Google map base layer. A requirement is to see the whole world, but only once: even at the lowest zoom level, the world must not be repeated.

My map div is 700px wide, and the size of the world displayed is a bit smaller, so it is displayed again on each side of the map.

So the question is: is it possible to display the world only once at the lowest zoom level, so as the antimeridian line touches the border of the map on each side, without resizing the map div?

The map I currently have is at http://beta.gogeo.ac.uk/cgi-bin/intl.cgi if it helps.


The options I used to do this are:
layer = new OpenLayers.Layer.Google("Google Normal", { 'type': G_NORMAL_MAP,
						       'sphericalMercator': true,
							MIN_ZOOM_LEVEL: 1 });

and the parameters of the map are:

maxResolution : 156543.0339,
projection : new OpenLayers.Projection("EPSG:900913"),
units : 'm',
maxExtent : worldExtent,
restrictedExtent : worldExtent,
wrapDateLine : true, //not sure where this one come from...

with worldExtent being (-180,-90,180,90) transformed to Projection("EPSG:4326").

All of this with OL 2.6RC1.

Thanks for any hint,

Guillaume

Is this new in 2.6, or if you go back to 2.5, does the same behavior
exist?

This is a problem with using the Google Maps API. I'm not aware of a way
to change this in the Google Maps API, but that would be the place to
look.

I don't think you can do that... unless your source TMS layer has only
two resolutions at the source?

An OpenLayers map can't display subsets of layers ina TMS layer at this
time: it's all or nothing.

This is new in 2.6.  It does not happen in 2.5.  The only thing that I
notice is that the lines are thicker in 2.5 and I don't know if that
is what is making the difference.  I am trying to come up with an
example but I have lots of layers and I have yet to figure out what is
causing the problem.  I had a similar problem in 2.5 when the minimum
resolution was not setting on calculateinrange on the layer.  But that
is not the problem with 2.6.  It is as though at the higher zoom
levels the lines just can't show up because they are being resized too
small.  Markers show up just fine but the vector lines do not.

Hey Bjorn-

Glad to see you find it useful.

For those who haven't followed recent style changes, the page below is a 
very nice use of "advanced context" for styles.

http://www.thematicmapping.org/experiments/openlayers/piecharts.html

Basically, you can have any value in a symbolizer (a symbolizer is what 
we used to call feature.style) be derived by any function that evaluates 
a feature for any feature property.  This includes feature attributes, 
feature geometry, or anything else you choose to store on a feature.

If you give an OpenLayers.Style instance a context property, then the 
all symbolizers will be evaluated in this context.  The 
styles-context.html example in our examples dir shows another use.

Bjorn, can you contribute these examples to our examples directory?  Any 
contributions of examples and documentation are greatly appreciated.

Okay, this doesn't sound beyond the realm of possibility. We changed
thickness of lines in 2.6 from being calculated in points to being in 
pixels.

Can you reproduce a minimal example of this, so that we can try and get
it fixed?

Andreas, I think this could be related to your VML change.

For the record, I've just tried this in IE6 and IE7 (putting a linear
vector feature on top of a map, setting numZoomLevels to 20, and zooming
far in) and had no problems.

(Thanks for yoru continuned bug finding efforts!)

For information, I just updated MapFish GeoStat code to use
OpenLayers' new style framework. I do have examples showing the
result, it's available in my MapFish sandbox. The code is available in
my sandbox, see [2]. This code will soon go into MapFish trunk.

Subject: [OpenLayers-Users] a control to display a static image
Message-ID: <47FE31AB.4010008@makina-corpus.com>

Hi list,

Is there a Layer or a Control in OpenLayers to display a simple static 
image in the map pane ?

What I need is actually is to superimpose an image on the map. I want to 
use this to draw a North Arrow. I though about using the new Attribution 
feature (which is great!) but it's layer-dependant. I want my image to 
be displayed anytime.

I can't find anything that fulfil my needs in the API doc. Did I miss 
something? Should I develop a new Control for this?

Regards
Gilles

What you're looking for is closest to a control, but I honestly wouldn't
even bother with that: instead: I'd do this:

<div id="map">      
  <div id="arrow" style="position: relative; top: 30px; left: 400px;">
    <img src="arrow.png" />
  </div>
</div>

It would be nice if the Attribution control picked up an attribution  
from the Map object too.

Christopher,

It's done. Take a look:

http://trac.openlayers.org/ticket/1108

I've changed the version of the ticket to 2.6 RC2, since this bug still
present in this version. This is the right procedure?

my best regards,

Pedro Simonetti.

Subject: [OpenLayers-Users]  Query Feature by Attribute and Zoom
Message-ID: <16613255.post@talk.nabble.com>


Hello,

I am fairly new to OpenLayers and GIS in general and new to this list.  I
have just setup an OpenLayers page.  I am using MapServer as my WMS Server
and my data is held in PostGIS tables. 

I would like to know how can I create a way for a user to input text and to
zoom to the feature specified by the text.  

An example of what I am trying to accomplish:  
Take the Feature Info Example at
http://www.openlayers.org/dev/examples/getfeatureinfo.html.  If I wanted to
make it so a user could type in a country name then have the map zoom to the
extent of the country, how would I do so?  It needs to be a general enough
example I could use it with any text field (for example, a Serial Number).  

I have found a few previous postings that seem to be asking a similar
question but not many answers.  Any pointers to a nice or ugly solution are
appreciated.

Thanks.

Greg

Hi Greg,

As an WMS Server doesn't publish the features themselves, you will have 
to use another method for the requested functionnality, even if the 
layers can remain in WMS.
1. If you don't have so many countries, you can grab the extents of each 
of them manually and build a simple html select list with the extents in 
the value field. OnChange, you will fire a function getting the extent 
and setting your map extent with it.
2. If you have many countries, or if these data change often, you can 
build a simple web service sending you a stream (JSON for example) that 
you will use to build dynamically the same list as above. On the server 
side you can use many OpenSource tools to perform that : either 
php/mapscript, or even ogrinfo, in fact any tool that will be able to 
open your dataset and read the shapes in it. Of course, it's even 
simpler if they are stored into postGIS ;-)

Hope that helps,

Guillaume

Message-ID: <47FE7DBE.2090208@neogeo-online.net>

Hi,
Is there a way to render the layers in another order than their original 
add-to-map order ? Something like priority on each of them ?
Most of the time, the bottom layer is a tiled layer that makes you wait 
while the surrounding tiles are loading, and your "working layers" can 
be interesting to render before that.

Thanks for any clue,

Guillaume

Guillaume,

Thanks for the quick response, this nudges me in a direction that will solve
this (plus I can expand on it to solve a couple of other related issues I am
sure I will have in the coming month or so).

It sounds like the simplest way based on what I already have knowledge of
then would be to:

Create a HTML form in which a user enters the point.
Create a CGI Python program that gets the proper zoom-to extent (maybe using
GeoDjango, I have used Django a bit before).
Dynamically output the new map webpage from the CGI program with the added
Zoom to Extent Line.

On rereading it, it sounds a bit different from what you suggested but the
same basic idea...  
 
I will post back in a week or so the results (and hopefully some code) in
case anyone is interested.  


Greg

Maybe GeoDjango is a little bit oversized for this kind of thing ;-)
Basically, you just need to pull the extent of where you want to zoom to 
on the client side and set the map extent with it.
By the way, you can even probably grab it from Geonames 
(http://www.geonames.org/export/web-services.html#countryInfo)

Cheers,


Guillaume

1. Use different hostnames for your different layers.
2.
http://dev.openlayers.org/apidocs/files/OpenLayers/Map-js.html#OpenLayers.Map.raiseLayer

(which is also lowerLayer, when passed a negative index)

1. yes, but it should speed up the whole thing, not indicate a specific 
drawing order shouldn't it ? But, sure, I should do that anyway.

2. that will change the organisation of the map, which is not the goal 
either.

would it be difficult to add a layer drawingOrder option and make the 
map render them in that order ?

Thanks

Guillaume

Not extremely, but I don't know that it's worth it for OpenLayers core.
It would mean looping over all the layers more than once (once to build
the drawing order, once to actually call moveTo) in Map.moveTo. Also, it
wouldn't help once the layers start drawing, so if you add a layer, call
setCente,r then add another layer, it wouldn't help.

In any case, feel free to take a look at Map.oveTo and see if it makes
sense.

Subject: [OpenLayers-Users] Performance vs number of layer
Message-ID: <47FE8AC4.4070809@mapgears.com>

Hi all,

Since we talk about performance on the dev list...
The more layer we add on the top of an openlayer application, the more 
the application slow down. One of my client's application has around 30 
ka-Map layers available. Let just say that if you switch them all to ON 
at the same time the application becomes a bit...irresponsive.

How much layer did other experience with? How much is too much?

I know performance really depends on the user computer so let's assume 
1CPU (Intel Pentium M 1.73 GHz if you want details), 1GB of RAM and 
Windows XP

With this application we can go up to 8-9 layers at the same time, it's 
slow, but after that it's just too slooooow.

As a solution for this specific case, I think of switching to MapServer 
layer for some of them. Then I could merge the layers displayed in the 
layer switcher as a single MapServer layer and make only one request. 
Would a functionality to merge Mapserver layer request to the same 
server would be a good idea?

Something like the following that would display 3 layers in the layer 
switcher but would be treated as a single one in when querying for a tile.
layer = new OpenLayers.Layer.MapServer( "OpenLayers WMS",
    "http://labs.metacarta.com/wms/vmap0",
    {layers: ['basic', 'road', 'city']},
    {gutter: 15});

I would say that you could do this in *a* layer switcher just as easily
with WMS as with MapServer Layers -- either one can accept multiple
layers in a request. However, I believe that this advanced level of
functionality belongs outside the OpenLayers.Control.LayerSwitcher.

It is a good idea in general though, and might help solve your problem.

There is a method...

GMercatorProjection.prototype.tileCheckRange = 
function(tile,zoom,tilesize) {

    var maxTile = Math.floor(this.getWrapWidth(zoom) / tilesize);

    if (tile.x < 0 || tile.x >= maxTile || tile.y < 0 || tile.y >= 
maxTile) {

        return false;

    }

    return true

}

Hi,

 

I have just tried to setOpacity on a framedcloud and cannot seem to make
it work the command is as follows:

 

function registerPopUp() {

      popup = new OpenLayers.Popup.FramedCloud("ppnt_p", new
OpenLayers.LonLat(0,0), new OpenLayers.Size(300,300), 'This is a test',
null, true, onPopupClose);

      popup.setOpacity(0.7);

      ppnt.map.addPopup(popup);

}

 

It does not seem to do anything at all. Is this support in Framedcloud?

Hi Eric,

We use Visual Studio 2005 and the server is in windows also.

So we can programme webservices but they don't allow to put a Linux server
because they say that they can not support it and they don't allow to put
the mapserver in the windows server because they are afraid it affect the
performance of the web server.

Of course I am pushing it, but I am afraid it takes some months :(
Maybe this does not make sense and I would agree with!!!!!!

So I can make a webservice visible to javascript and this will be a
temporary solution.

Thanks for your help,

Carlos

For your information, MapFish already provides a layerTree which
allows to build the advanced layer switcher Chris is talking about.
You can do it yourself quite easily too if you need something really simple.

Hi David,

FramedCloud Popup extends Framed Popup, and inside this class, you'll find
the answer to your question :

setOpacity:function(opacity) {
   //does nothing since we suppose that we'll never apply an opacity
   // to a framed popup
}

... But I guess you could apply some opacity to the cloud-popup-relative.png
image with an image editor, and that would do the trick if you do not need
to adjust opacity programatically.

Subject: [OpenLayers-Users] Can Openlayers read a GML from a webservice?

Hola Carlos,

I never done it before, but you CAN do what you want.
You can read GML from a web service, but for reading from a SOAP web
service it will need more code on the client.
In the terms of .NET platform, you should create a ASP.net handler
(.ashx) or a ASP.NET page (.aspx), and generate the GML file with
Response.Write (don't forget the HTTP headers). I think that using a
'Web service' (.asmx) will be more difficult because of all the SOAP
envelops.

Hope this helps.

I'm seeing the same issue with the trunk code at the moment, removing
the deactivate from the
featureAdded handler stops the error but i need a work around?

any ideas?

Did this work in 2.5? (Is it a regression?)

I am only seeing this with OpenLayers.Handler.RegularPolygon which
seems to be exactly like
the other handlers in  to http://trac.openlayers.org/ticket/1143

this.layer has no properties
[Break on this error]  this.layer.renderer.clear();
RegularPolygon.js (line 365) (trunk)

whilst using a done callback, both featureAdded and done callbacks
throw an error
when deactivating a control ( also on 2.5)

Please forgive a minor hijack, can anyone point me to an example app using
FramedCloud?

'app'? Probably not; it was only added to trunk immediately before RC1.

 * http://openlayers.org/dev/examples/sundials.html
 * http://openlayers.org/dev/examples/select-feature-openpopup.html

Both use it though.

Subject: [OpenLayers-Users] identifying map regions/features on the client
	side
Message-ID: <1207926575.6714.29.camel@charon>

Hi

I'm wanting to identify whether a mouse is clicking on (or hovering
over) a region on my OpenLayers map and then do various things in
response based on the identity of the region. (such as showing country
information if you click on a particular country)

I've implemented this by sending an x,y via AJAX off to the server, then
getting the region identifier back and then doing the things in
response. But unfortunately this can be quite slow with network
latencies between the browser and server.

It seems that a more responsive approach would be to do the region hit
calculation client side. 

I'm guessing a Vector layer approach might facilitate this but as I
understand it Vector (SVG/VML) layers aren't capable of showing very
detailed maps and have cross browser "issues".

I've seen a few enticing posts in the archive mentioning the possibility
of adding an imagemap based approach to this sort of problem but nothing
concrete seems to have happened.

So I'm thinking a new layer type might provide this which would use much
the same info as a vector layer uses (GML, KML etc.) but instead of
rendering this vector info it would provide methods to identify the
feature at an x,y location.

Have I missed something? Am i barking up the wrong tree?

cheers,
Graham

You don't even need a layer.

1. When your application loads, load your country data into the client,
   using Format.GML, Format.GeoJSON, etc. Even in relatively slow browsers,
   this is probably only a few seconds of time.

2. When a user hovers, do a:
 
  var selectedCountry = null;  
  var g = new OpenLayers.Geometry.Point(x, y);
  for (var i=0; i < myFeatureList.length; i++) {
     if (myFeatureList[i].geometry.intersects(g)) {
        selectedCountry = myFeatureList[i].attributes.country_code;
     }
  }

Then display your information.

Ah excellent.. this seems to be a 2.6 bit of functionality, time to
check out the release candidate!

Subject: [OpenLayers-Users] Transparent WMS overlay on top of a Google layer
Message-ID: <20080411215132.GA32367@iks-jena.de>


Hi,

could anyone please point me to a working example of a transparent 
WMS layer as overlay over a Google Maps layer in EPSG:900913 projection?

My current attempt looks like this:

    var options = {
      projection: "EPSG:900913",
      units: 'm',
      maxExtent: new OpenLayers.Bounds(
        1272516.0, 6585124.3, 1319786.0, 6632981.0),
      controls: [new OpenLayers.Control.MouseDefaults()]
    };
    map = new OpenLayers.Map('map', options);

    l_gsat = new OpenLayers.Layer.Google('Google',
      {type: G_SATELLITE_MAP, 'sphericalMercator': true} );

    l_rr = new OpenLayers.Layer.WMS('Radrouten',
      'http://wms.adfc-jena.de/rrtop.php?show=all',
      {layers:'Radrouten', format:'img/png', transparent:'true'},
      {'reproject': false, 'isBaseLayer': false}
    );

    map.addLayers([l_gsat,l_rr]);

Complete example is at: http://www.adfc-jena.de/karte/radrouten1.php
The Google layer is being displayed but the WMS server never gets queried.
I played around changing parameters but without avail.

(The WMS server is not a complete implementation but does only simple GetMap
queries. It works fine as a single layer in OpenLayers though.)

What I'm doing wrong here? Any help is greatly appreciated. 
I am using OpenLayers-2.5 for now.

Thank you in advance,
Erik

Hi Erik,

You're nearly there! You need to set a maxResolution option, say: 

maxResolution: 156543.0339,

for example. I don't know why that is (can somebody please explain?). 
You also need to change you projection to a projection object instead of 
a string (although in your example you can get away with it). See [1] 
for more information.

Regards,

Roald

There are a couple ways to get an extent.

1. Making a non-WMS call to mapserver like:

   http://localhost/cgi-bin/mapserv?map=/path/to/mapfile.map&mode=itemnquery
     &qitem=id&qstring=123456&qlayer=ownership&mapext=shapes

Using a simple mapfile like:
    [minx], [miny] [maxx], [maxy]

Would return the extent of the feature(s) where id=123456. You could
then use those values to set the OL extent. You can also use itemquery
and itemnquery modes to highlight feature(s).

2. If your data in in PostGIS you can call the extent() function e.g.:

    SELECT extent(the_geom) FROM sometable WHERE id=123456;

I have a small php page that I call with the query parameters and it
returns the extent, which I then use to set the extent in the browser.
In the mapfile I have a layer styled with a bright highlight. The
layer has a filter so I again pass the id=123456 to select the objects
that I want to highlight e.g.: FILTER "%id%"

These suggestions may not be the WMS way, or the OL way, but they are
tried-and-true MapServer methods for highlighting features and getting
extents.

David,

 

You can see it running on my site. I have only added it with static data and will be modifying my WMS calls to use it next week.

 

See these pages:

http://www.exploroz.com/Directory/Categories/Campers_Trailers.aspx (Right hand side map uses random data selection)

http://www.exploroz.com/Places/28159/NT/Ayers_Rock_Uluru.aspx (there are 77000 pages in places and this is just one)

 

You will see the framedcloud in action in the places pages next week, the WMS queries (Add New Layer) will be utilising the framecloud's with maybe a dynamic WFS data call to populate the popup.

... But I guess you could apply some opacity to the cloud-popup-relative.png image with an image editor, and that would do the trick if you do not need to adjust opacity programatically.

Hi David,

FramedCloud Popup extends Framed Popup, and inside this class, you'll find the answer to your question :

setOpacity:function(opacity) {
   //does nothing since we suppose that we'll never apply an opacity
   // to a framed popup
}

Hi,

It seems it is not possible with 2.5. But if you use 2.6 look here:

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

Perhaps with loadRSS it's possible.

loadRSS() does northing if the RSS doc was already loaded. You can probably do:

layer.loaded = false;
layer.loadRSS();

to force reload.

Note that this operation relies on properties that aren't part of the
API. These properties can therefore be removed or renamed in future
versions of OpenLayers.

If you want your app to rely on API properties only, you can probably
create a new GeoRSS layer each time you need reloading the GeoRSS
document. If you think this isn't appropriate and a reload() API
method is required, come up with good case for introducing this API
method and it will be considered for inclusion into OpenLayers.

Cheers,

In the regularPolygons example, if you switch the base layer to
google, you can't
draw beyond a certain resolution, the polygons get created but not
drawn on screen,
if you zoom back in in they appear.

Also if you draw a polygon say over Africa, and then start to pan
across the globe, the
polygon then starts to re-appear in different places all over the map?

var bounds = new OpenLayers.Bounds(103.944322120274,30.633607944233,104.154306379013,30.8435922029719);

"One that works." It should do GeoRSS Simple in 2.5, and GeoRSS Simple
+ GML in trunk. It should do GeoRSS 2.0, Atom, and I think there's
support for RSS 1.0 + w3cgeo in 2.5 and trunk as well.

Paste your RSS into http://openlayers.org/dev/examples/vector-formats.html 
and select GeoRSS to check.

My first answer to any and all Google problems is likely to be "Does it
happen when you use Spherical Mercator?"

In this case, the answer is a resounding 'no': So I'd suggest that you
use spherical mercator with any Google layer you plan to draw on top of.

OpenLayers does not have the ability to load a subset of tiles
from a TMS layer: you get 'all or nothing'. If you control the
generation of your TMS tiles, you can change your maxExtent and
maxResolution on the server to match the ones used on the client, and
TMS will work.

I am trying to understand the spherical mercator example
http://openlayers.org/dev/examples/spherical-mercator.html
So I copied the source to my website, changed the relative reference for 
the OpenLayers script to
<script src="http://openlayers.org/api/OpenLayers.js"></script>
and changed the Google API key to the one for my website.

When I open this page I get the following error in Firebug:
OpenLayers.Projection is not a constructor
    projection: new OpenLayers.Projection("EPSG:900913"),
Can anyone tell me what I am doing wrong?

Thanks, Tara

Hi Tara,

I think http://openlayers.org/api/OpenLayers.js will return you 
openlayers 2.5, and Projection is available in trunk/2.6
So you have to get trunk and build a OpenLayers.js yourself (or point to 
the OpenLayers.js of the example itself?

Or if you download 2.5 from: 
http://www.openlayers.org/download/OpenLayers-2.5.zip
in the examples dir of that one there is a spherical-mercator.html which 
doesn't use Projection (yet).

Hope this helps,

Regards Richard Duivenvoorde

It appears that this never got filed in a ticket, so it didn't enter the
collective memory of the project as effectively as it might have. Feel
free to file it in trac, and we'll look at it for our next release.

I've done some more digging and found that "<center>" tag (either the 
<center> in html or {text-align: center} in css) will cause this problem 
in IE.  If I remove "<center>" in my html it will display fine.

 Hello dear everyone,
    I find when I zoom in,zoom out or pan the map, the map in the overview-map is also zoomed in/out or moved. In my opinion,the overview map is called overview-map, because when I zoom-in the main map in a certain zoom-level and we do not know where the positon I am in the all map, it can show us a overview. But now the overview map is zoomed and moved following the main map,how it can play the role of a oveview-map? I want to know is there a way to let the map in the overview-map do not been moved and zoomed.Could you please give me some suggestions?Thank you very much!

Hi,

use something like:

isSuitableOverview: function() {return true;}

in your overview map constructor.

Example:

var overviewmap = new OpenLayers.Control.OverviewMap( {layers:
[overviewlayer], size: new OpenLayers.Size(225, 180), minRectSize: 10, div:
overviewdiv, isSuitableOverview: function() {return true;}, mapOptions:
options});

Subject: [OpenLayers-Users] style externalGraphic and WFS new vector layer
Message-ID: <16677397.post@talk.nabble.com>


Hi all,

and first nice to work with OL. Many things of what I will do work's as good
as could,
but with one thing I get on my bounds and need some help from you.

I will use my own server side images with OL. It works great with a vector
layer and a
vector feature, where the style is set to externalGraphic: "........" and
many other style defines.
Also the dragging mechanism works fine.

Now I have a consideration, but I don't know if it's true. If a WFS layer
was defined as a new vector layer, meens without a featureClass definition,
than all features of that WFS layer has a predefined style. If that true,
and my debugger say yes, than it will be possible to add the
externalGraphic, and a reference to my images on the server side, attribute
to every style of the features. 

Is this consideration absurd, or is it a possibility to work with WFS
features in mode of vector and combine it with external graphics of my own?

Thanks,
Klaus

Hi all,

now if have try it again and it works, cool.....

I have set it up like this:

    var style_em = OpenLayers.Util.extend({},
OpenLayers.Feature.Vector.style['default']);
    
    style_em.fillOpacity        = 1;
    style_em.fillColor            = "#000000";
    style_em.pointRadius      = 0;
    style_em.graphicWidth    = 64;
    style_em.graphicHeight   = 44;
    style_em.externalGraphic =
"http://server/geoserver/prototyp/img/picture.gif";


    var wfs4 = new OpenLayers.Layer.WFS( "EM",
           "http://server/geoserver/wfs?", { typename: 'WFS:em'},
           {
               style: style_em
            });
     map.addLayer(wfs4);

Thats a very nice feature,

Hi Tim,

Thanks for the heads up. I have a geocoder that returns XML in addition 
to other formats and needed to parse it. I got a headache trying to 
figure out how to get my results out of the parsed document and switched 
to another format that was easy to parse into an array of objects.

So I'm good.

WRT the documentation, you might want to add a note to it or mark it as 
deprecated or whatever.

Thanks,
   -Steve

Message-ID: <f4c7e92f0804141208i4a2f4cc9ncd7f5702b0966be9@mail.gmail.com>

Hi all, I've tried searching but haven't quite found what I'm looking for so
I hope this isn't a repeat post.

I have all the US counties displayed as features from featureserver in an
openlayers map.
My problem is, every spot on the map always displays a feature (counties are
everywhere), so if the user clicks anywhere on the map, it's the same thing
as selecting a feature.
If clicking anywhere on the map selects a feature, the only way to pan is
using the arrows.
Example: http://pocus.wustl.edu/wfs/

Anyone know if it's possible to disable the select and force a pan, maybe
using the shift key or any other modifier or maybe another icon somewhere?

Any help would be greatly appreciated.
Thanks!

Yes, this is what the Control.Panel is designed for: see
NavigationToolbar, EditingToolbar, etc. Also, most of the OpenLayers
examples of controls do this in a way that you can replicate at the
application level. I suggest looking at the examples to get a feel for
the way to do this, or at the panel.html for an example of creating your
own panel.

be getting WKT for road segments from a database, and I want to highlight
those segments on a map. However, I haven't been able to get past this
error:
Error: uncaught exception: [Exception... "String contains an invalid
character"  code: "5" nsresult: "0x80530005
(NS_ERROR_DOM_INVALID_CHARACTER_ERR)"  location:
"http://openlayers.org/api/OpenLayers.js Line: 554"]

Here is the code I was using:

<html xmlns="http://www.w3.org/1999/xhtml">
  <head>
    <style type="text/css">
        #map {
            width: 762px;
            height: 825px;
            border: 1px solid black;
        }
    </style>
    <script src="http://openlayers.org/api/OpenLayers.js"></script>
    <script
src="http://maps.google.com/maps?file=api&v=2&key=ABQIAAAAIeWnOWItAsdtOsR3kxiUQhTwM0brOpm-All5BF6PoaKBxRWWERSQAgEHUq2jStqEx-kpNgzntg87iw"></script>

    <script type="text/javascript">

         var result_style = OpenLayers.Util.applyDefaults({
             strokeWidth: 7,
             strokeColor: "#ff0000",
             fillOpacity: 0
         }, OpenLayers.Feature.Vector.style['default']);

        function init() {
            var map = new OpenLayers.Map('map');
			var google = new OpenLayers.Layer.Google( "Google", { type: G_NORMAL_MAP
} );
            var highlight = new OpenLayers.Layer.Vector("highlight", {style:
result_style});

			map.addLayers([google, highlight]);

            var parser = new OpenLayers.Format.WKT();
            var wkt = "LINESTRING(-73.9444 40.75921,-73.96892 40.76396)";
            var geometry = parser.read(wkt);
            var feature = new OpenLayers.Feature.Vector(geometry);

            highlight.addFeatures([feature]);
            map.zoomToExtent(new
OpenLayers.Bounds(-74.0472500,40.6795100,-73.9071900,40.8820000));
        }

    </script>
  </head>
  <body onload="init()">
    <div id="map"></div>
  </body>
</html>

I tried lots of different variations, but nothing that proved useful, so I
left them out. Can anyone spot my issue?

Thanks in advance, 
Craig

The WKT format returns Features, not geometries.

Should just be:

Subject: [OpenLayers-Users] Maximum extent shrinks when zooming in
Message-ID: <4803EA0F02000053000353C1@stirling.iso.port.ac.uk>

Hi, I am using OpenLayers with Tilecache and MapServer. When I zoom into
the map the right and top maximum extents of the map shrink. This does
not happen with every zoom, it seems to occur every alternate zoom. The
left and bottom extents are not affected.

Initially, I thought it could be a Tilecache issue, so I disabled that
but it did not help. I also tried setting maxResolution to auto rather
than 8000.0, but that didn't work either. Specifying a resolutions array
also did not solve the problem.

My map is in LCC-ETRS89 projection (epsg:3034) and my maxExtent is
600000, 600000, 6000000, 6000000. I have numZoomLevels set to 12.

Another weird thing I noticed is that when I alter my maxExtent by a
small amount (eg +- 100000) then the extent of the map may not change.
It will only change if I specify a larger change in the maxExtent. I
don't know if that is related to the problem.

Does anybody have any ideas how to fix this or what could be causing the
problem? Have I discovered a bug in OpenLayers? :)

Please help!

Hi!
 
First, excuse me for my English, I'm french and you'll find many mistakes in this mail. ^^
I'm writing to you because I have a very strange probleme with OpenLayers.
I'm using Mapserver for my student placement and then, I want to show the image that I obtain. No problems with that. Now, I want to provide to the user, the possibility to pan the image, to zoom in and out. So I discover openLayers and try to use it!
But when I try to see my map, I obtain a white image. I join you my code. 
Can you tell me my mistake?
 
Thank you for your help and the comprehension of my very poor english.
 
Clement

it's not clear from your sample code if you passing in a lat lon and zoom?

if that's missing openlayers doesn't know what to display and you
don't get a map

installing firebug for firefox is really useful to debug any problem
you might be having,
as is livehttpheaders

Hi!
I'm fighting with my map and OpenLayers and it's very hard ^^.
OpenLayers print me a white image and if I put the image URL and clear the end, added by OpenLaysers (for &map_ext...), my map is OK.
What can I do because my URL is good and it's the programme which added something which give me a white image.

Thanks for your help and sorry for my english;

I just encountered something similar with the latest MS4W.  I was 
getting an error on the image requests:

loadForm(): Web application error. Invalid mode.

but when I change the MapServer URL from 'localhost' to

http://127.0.0.1/cgi-bin/mapserv.exe

it worked, not at all sure why.

Below is my what I ended up with to draw a line. 

When I pan the map North and South, the line does not stay fixed relative to
the map - can someone please tell me what the issue is here?

Subject: [OpenLayers-Users] (Openlayers + Mapserver) not able to dispaly
	Raster image.
Message-ID: <741324.97038.qm@web31808.mail.mud.yahoo.com>

I used Mapserver + Openlayers. I can load shp data and display it (The image displayed in openlayer is small). However, somehow I am not able to display any raster map even. I only see a blank rectangular on my web browzer.  I can use shp2img utility to generate this image. It just didn't display in the openlayer. 


Thanks in advance..

I checked the zoomLevels example that comes with OpenLayers and this suffers
from the same problem. So I guess that this means it is a bug in OpenLayers.
Any idea when it may be fixed?




I am using OpenLayers with Tilecache and MapServer. When I zoom into the
map the right and top maximum extents of the map shrink. This does not
happen with every zoom, it seems to occur every alternate zoom. The left
and bottom extents are not affected.

Thanks to Guillaume and Brad for their suggestions to get me on the right
path, I have the feature working as I wanted now.

I decided to use GeoDjango because I will be doing some other tasks with it
in the future.  Getting the transform function in GeoDjango took quite a bit
of work (I ended up hacking the django/contrib/gis/gdal/libgdal.py file and
setting the lib_name manually to the location of my libgdal.so file).  All
of the other instructions on the GeoDjango Wiki worked for me.

After getting everything installed and working, actually adding the zoom by
attribute feature was the easy part.



If a code example would be useful for anyone, here is how my Views file
looks:

# Create your views here.
from django.template import Context, loader
from django.http import HttpResponse
from tcecmapviewer.basicviewer.models import *
from django import newforms as forms

def index(request):
    if request.method == 'POST':
        mapForm = MapForm(request.POST)
    else:
        mapForm = MapForm()
 
myModel=MyModel.objects.all().filter(tagnumber=mapForm.data['TagNumber'])
    OpenLayersZoom=GetOpenLayersZoom(myModel)
    t =
loader.get_template('/var/django/tcecmapviewer/templates/index.html')
    c = Context({'OpenLayersZoom': OpenLayersZoom, 'mapForm': mapForm})
    return HttpResponse(t.render(c))


class MapForm(forms.Form):
    TagNumber=forms.CharField(max_length = 20)

def GetOpenLayersZoom(Object):
    if(Object):
        OneObject=GetOne(Object)
        point=OneObject.Point.transform(4326, clone=True)
        return "map.setCenter(new OpenLayers.LonLat(" + str(point.x) + "," +
str(point.y) + "), 14);" #Zoom into the point Object
    else:
        return "map.setCenter(new OpenLayers.LonLat(lon, lat), zoom);"

def GetOne(ListOrObject):
    """Helper Function, return the 1st object in a list or the object"""
    try:
        return ListOrObject[0]
    except:
        return ListOrObject





My index.html (Template) file looks like this [modified slightly]:

<html xmlns="http://www.w3.org/1999/xhtml">

    <script src="/mapserver/lib/OpenLayers.js"></script>

        var lon = -80.9;
        var lat = 33.7;

	var options = {maxResolution: 0.17578125, numZoomLevels: 18,
maxExtent: new OpenLayers.Bounds(-83, 33, -79, 35),
		'tileSize': new OpenLayers.Size(512,512)};
        function init(){

            LayerNetwork = new OpenLayers.Layer.WMS("Network",

		     {'buffer':0});
            map.addLayer(LayerNetwork);
	    {{ OpenLayersZoom }}

Subject: Re: [OpenLayers-Users] Query Feature by Attribute and Zoom

Maybe GeoDjango is a little bit oversized for this kind of thing ;-)
Basically, you just need to pull the extent of where you want to zoom to 
on the client side and set the map extent with it.
By the way, you can even probably grab it from Geonames 
(http://www.geonames.org/export/web-services.html#countryInfo)

Cheers,


Guillaume

Subject: [OpenLayers-Users] Openlayers displa.. size of the map very small.
Message-ID: <390230.62254.qm@web31812.mail.mud.yahoo.com>


I downloaded a demo which display a nice map through mapserver. The image is like this.
http://www.mobilegeographics.com/mapserver/usa1.phtml

The image is big and nice. 

When I changed it to display throught openlayers. The openlayer map only display a blank windows with all controls. If I change the "proj=lcc" to "proj=latlong" , then it display a map but the size of the map is very small and only occupied the upper lift corner of the openlayers div. Is there any way to make  display fit the windows?

Would like to take any suggestion. Thanks in advance!

I don't consider anything you've thus far described a bug, so as far as
I know, there is no plan to change it.

Here is the regular raster image in browser without using openlayers.
http://www.imagewoof.com/view_image/6dd5d1350/raster-noOpenlayers.JPG

The URL is like this :
http://localhost/tmp/48051072_121c_0.png

If I use openlayers to load it. It shows a blank page and the URL is like

http://localhost/cgi-bin/mapserv.exe?map=C%3A%2FProgram%20Files%2Fms4w%2FApache%2Fhtdocs%2FMSrecipes%2Fusa3.map&mode=map&map_imagetype=png&mapext=-180+-90+180+270&imgext=-180+-90+180+270&map_size=256+256&imgx=128&imgy=128&imgxy=256+256


Thanks a lot!

Take a look at these 5 lines from your map file:

     EXTENT -8000000 300000 5000000 1500000
     UNITS METERS
     PROJECTION
               "proj=latlong" "lat_1=32" "lat_2=44" "lat_0=38" "lon_0=-100"
"x_0=0" "y_0=0" "ellps=GRS80" "datum=NAD83"
     END

You are telling MapServer that your image extent is 13 million degrees in
the x direction.

Your EXTENT and UNITS need to be of the same units as your output
projection.

Try UNITS "dd" and convert your extent to degrees.

David.

Hi Christopher,

That's interesting that's it's not considered a bug. Personally, I would
definitely think of it as a bug or possibly an undocumented feature :) I
hope you don't think that I was complaining, I think that OpenLayers is
great. 

I think I have found a solution to the problem: Use the restrictedExtent
keyword, I think that will do the trick. :)

Keep up the good work and I look forward to v2.6

Well, if you think there's a bug, you need to do further description of
the issue to convince me, is all. What you have described so far sounds
to me to be not a bug. What you have described so far sounds to me like:

 * I have a map, from (for example) -10, -3, 10, 3
 * I set a maxResolution of 6 / 256, so that my whole world fits
   vertically within one 256 px tile
 * Because my map is 20 units wide, it is 4 tiles wide, and therefore
   covers more than -10 -> 10 in the longitude direction: 24 degrees.  
 * When I zoom in, my resolution drops to 6/512:
   * Vertically, the world is two tiles. 
   * Horizontally, it is 7 tiles -- taking up less horizontal
     geographic space than before: 21 degrees.

Since you've said you can change your maxResolution, and it 'solves' the
problem, I assume that you've found that if you pick a maxResolution
that divides *evenly* into the width *and* height (in this case,
something like '2' would do: 3 tiles high, 10 tiles wide), you will see
that the tiles match your geographic space correctly.

If this is *not* what you're describing, then you'll need to be more
clear, because this behavior isn't a bug: in fact, I don't know of any
way around it.

In-Reply-To: <ed718af50804151352od004badv5274de4635d5b9cf@mail.gmail.com>
Message-ID: <649316.2922.qm@web31811.mail.mud.yahoo.com>

I used the same Map file for the following scenario:
1. using mapserver utility "shp2img" and it generated a 800x500 image (Good size).
2. mapscript + mapserver and it generated a 800x500 image (Good size)

3. openlayer + mapserver and no display.

4. If I change "proj=lcc" to "proj=latlong". openlayer + mapserver generate a 256x256 small image.

Does this mean openlayers can't handle mapfile "proj=lcc"?

Is there a place in openlayer code I can make mapserver generate a 800x500 image if I used "proj=latlong"? 

Thanks!

Hi Christopher,

Thank you for your swift reply. You are probably right that it is not a bug,
I will have to do some further investigation and report back. I have a bit
of deadline at work at the moment, so it will have to wait.

Actually I never said that changing maxResolution solved the problem. In my
first post, I said changing it to 'auto' did not solve the problem. Using
the restrictedExtent keyword, however, has 'solved' the problem :)

Best Regards,

John Westwood  (zenzero-2001)

No, it means that you need to specify a different set of projection
parameters.

Subject: [OpenLayers-Users] OpenLayers 2.6 Final Release
Message-ID: <20080416004143.GA29395@metacarta.com>

The OpenLayers Development Team is proud to announce release of
OpenLayers 2.6.  As of this final release, the OpenLayers 2.6 release
closes 294 outstanding tickets, 75% more than any OpenLayers release to
date. 

The OpenLayers.js hosted at

  <script src="http://openlayers.org/api/OpenLayers.js"></script>

has now been changed to use the 2.6 API.

As always, the source is available at http://openlayers.org/download/.
  
  md5sums:
    ce957a47ad9bc8356d990417d61cc8a4  OpenLayers-2.6.tar.gz
    43c82d5a9ae9e0b18c1fa37a97065e02  OpenLayers-2.6.zip

This is a large release: the largest of any OpenLayers release to date.
This release features a number of major developments, including:
  
  * Integration of the CloudAmber "Google Like" popups for advanced
    visual display of information in popups
    * Resulting improvements throughout all popup code, including
      autosizing popups to the content they contain.
  * Improved panning of commercial layers like Google Maps and Yahoo!
    Maps
  * Animated panning of the map, using OpenLayers.Tween support
  * Layer Image transitions, for keeping images visible when zooming
    to allow smoother transitions
  * Client side reprojection support using built in transformations for
    spherical mercator, or the proj4js library for other projections.
    * Support for reprojecting vector data layers
    * Support for reprojecting user-facing controls like mouseposition
    * Support for programatically reprojecting points and geometries 
  * Improved OpenLayers Styling, including:
    * OpenLayers.Style, OpenLayers.StyleMap, OpenLayers.Rule,
      OpenLayers.Filter support for improved feature-attribute based
      styling
    * SLD read/write support 
  * Support for reading and writing multiple versions of WMC.
  * Improved KML support, including KML styling support.
  * Improved GeoRSS Format support, including GeoRSS GML read support.
  * New ScaleLine Control for displaying visual scale
  * New NavigationHistory control for map history navigation
  * Localization/Better Internationalization support
  * Layer support for MapGuide Open Source 
  * A number of new / improved handlers to make handling user
    interactions easier
     * Handler.Hover
     * Handler.Click
     
A thank you again to all the people who helped to make this release
happen. My earlier post[1] on the topic covers that as well as any
single email can hope to. 

We look forward to your feedback!

Subject: [OpenLayers-Users] (Openlayers + Mapserver) not able to dispaly
	Raster image.

Message-ID: <202599.84027.qm@web31803.mail.mud.yahoo.com>

Hi Chris

Thanks for your patient. I am still getting empty box in my browser. There is no image in the box so I could't even copy the image URL.

Here is what I did.
1. load a raster image to qgis and export to generate below mapfile.
2. use shp2img to verify the mapfile can display correct picture.
3. Base on the mapfile content, I set maxExtent, maxresulotion (6086744.000000 + 4278894)/800 = 12957), and EPSG:4326.
4. refresh webbrowser and get a empty box without any image.

Any suggestion is highly appreciated.

Subject: [OpenLayers-Users] Node was not found error
Message-ID: <480583A4.6050205@alt2is.com>

I would like to thank everyone who has patiently answered my questions. 
I am learning javascript for the sole purpose of creating OpenLayers 
maps, so it is often difficult for me to understand documentation that 
is written assuming the user is a javascript wizard, but I am making 
progress and have some working maps.

One of my OpenLayers maps is running correctly, as near as I can tell, 
but it shows the following error, according to Firebug:

Node was not found" code: "8
[Break on this error] 
if(layer.isFixed){this.viewPortDiv.removeChild(layer.div);}else{this.layerContai...
OpenLayers.js (line 529)

Is this something I should worry about?
If so, how can I track the problem back to my script?

Subject: [OpenLayers-Users]  ScaleLine km only
Message-ID: <16717688.post@talk.nabble.com>


Hi All,

Using Openlayers 2.6 and coding a map using the ScaleLine control a la:
map.addControl(new OpenLayers.Control.ScaleLine());

My client wishes it only to display kilometres and not miles. Is there any
way to configure this? Or will i have to code a hack or design my own custom
scale which swaps in and out for each zoom level? Apologies if this is an
easy one, but the docs/api and searching through usergroups didn't give me
any joy.

Cheers in advance,
Regards,
Matt

check the properties topOutUnits &  topInUnits

there is a bug with IE if you try and hide the bottom or top set by
setting these
values to be empty

Message-ID: <a80aba890804160203n4418c852u82d70f5f9d4c57a6@mail.gmail.com>

I'm using the brand new 2.6 (well done guys!) but I haven't try with
older versions, so...
In my website I'm using OpenLayers and NavToolBar component, that
implements a ZoomBox handler for a zoom rect funtion that works well.
I've tried to add this custom components, taken from the openlayers
samples, and i have a strange behavior:

var customBox = new OpenLayers.Control();
    OpenLayers.Util.extend(customBox,
    {
        draw: function ()
        {
            this.box = new OpenLayers.Handler.Box(customBox,
                { "done": this.notice },
                { keyMask: OpenLayers.Handler.MOD_SHIFT });
            this.box.activate();
        },

        notice: function (bounds)
        {
            var ll = map.getLonLatFromPixel(new
OpenLayers.Pixel(bounds.left, bounds.bottom));
            var ur = map.getLonLatFromPixel(new
OpenLayers.Pixel(bounds.right, bounds.top));
            alert(ll.lon.toFixed(4) + ", " +
                ll.lat.toFixed(4) + ", " +
                ur.lon.toFixed(4) + ", " +
                ur.lat.toFixed(4));
        }
    });


If i add this component to the map, when i try the code all works well:
the navtoolbar is in "pan" state so i could pan the map as usual, and
using shift i could drag a zoombox and show the bounding box
coordinates.
If i select the zoomrect tool from navtoolbar i lost the behavior of
the custom component :(
Any try to use shift + zoombox generates the behavior of the zoomrect tool.
any suggestion?

Subject: [OpenLayers-Users] problem with tilecache layer
Message-ID: <007e01c89fa4$d86f12b0$894d3810$@gadenz@jrc.it>

Hi all!

 

I have a strange bahavior (error?)wrapping the dateline in a tilecache
layer. The column of tiles poistioned right after 180 longitude load empty
images. 

 

This is one of the image url that is asked to the server:
http://139.191.68.15/tscache/pop04sm/02/000/000/004/000/000/001.png. In fact
the folder 02/000/000/004 does not exist in my cache hierarchy.

 

The definition of the layer into the page is:

 

var tiledpop = new OpenLayers.Layer.TileCache("World Population 2004 (1km)",

                ["http://139.191.68.15/tscache/"],

                "pop04sm",

                {

                    'format': 'image/png',

                    'isBaseLayer': false,

                    'opacity': 0.6, 

                    'reproject':true,

                        'wrapDateLine': true, 

                        'singleTile': false, 

                        'gutter': 1

                }

            );

 

Any idea?

Great work guys - looking forward to playing with the latest version!

I know its only 9 hours old, but the openlayers.org homepage still refers to
2.5, and I cant figure out a way to login and change it for you ( the
homepage doesnt seem to be part of the wiki?).

Subject: [OpenLayers-Users] tiling features to speed detecting features on
	the client
Message-ID: <1208342288.6397.40.camel@charon>

In a previous post I said that I wanted to detect which feature a mouse
had clicked on at the client side in order to be more responsive. The
suggested solution worked well, that of downloading a geojson
representation of the features up front and using the 2.6 OL feature of
detecting whether the feature's geometry intersected with the mouse
point.

However for large maps, downloading the features in geojson (or another
format) of the required detail for all zoom levels for detecting which
feature is being clicked on is prohibitively large.

So this got me thinking, how about tiling the feature information, or
rather the geometry associated with it? 

On the server side I can see a way of hacking TileCache to generate a
geojson feature "tile" by clipping the feature geometry to the tile
bounds and then quantising the geometry by the tile resolution (using
some shapely, worldmill & geojson sauce).

On the client side a new type of OpenLayers Layer would download these
feature "tiles" in parallel with the image tiles and provide access to
the "visible" features for mouse click detection etc.

I don't need to do this but I guess you could also render these "tiled"
features and possibly get around some of the browser problems of
rendering vector layers with too many vectors or vertices because of the
geometry simplification of the tiling & quantisation.

Is this madness? Am I missing something that exists already that would
achieve what i want.

thanks,
Graham

Nope, it's in SVN. I passed out last night before I finished updating
everything; I've gone ahead and finished up now.

That's definitely a bug of some kind. Can you share your HTML? It looks
like it's happening in the setBaseLayer function...

Hi Graham,

There is an implementation of something similar to this in the WFS  
Tile code, and there is also substantial new work being undertaken by  
Tim Schaub to introduce Vector Behaviours which will be a much more  
sophisticated way of managing this.

Message-ID: <1208352435.6397.60.camel@charon>

I've just had a quick look at the WFS layer & tile code and can see how
this is similar to what I'm thinking of but it doesn't seem to have a
concept of "griddedness" or tile resolution. In order for the server to
be able to reduce the detail of the feature geometry it would need
something like a width & height parameter sent in the request. Also I
was imagining that quantising & clipping a feature geometry might be
quite resource intensive on the server and so tiling the requests would
allow caching or pre-generation in a similar manner to TMS or WMS-C. 

So maybe I could implement a subclass of OpenLayers.Layer.Grid that
generated requests in TMS or WMS format and then parsing the features
returned in a similar manner to the OpenLayers.Layer.WFS class.

Sorry for my GIS ignorance but does WFS support the notion of reducing
the detail of a feature geometry in response to a request? I had a look
at the spec and can see mention on limits on the number of features and
conditions on their properties but not about the level of detail.

cheers,
Graham

Subject: [OpenLayers-Users] popups for markers dynamically generated from KML
Message-ID: <8A94DF1034BA03408EC040C33C42D3BA7281A1@XCH23YOW.rim.net>

I know there is a KML parser and examples that render graphics based on
KML inputs.  Since some of the KML sources I'm using are particularly
huge, instead of having the KML parsed on the client through OL, I have
a server-side KML reader (uses XPath/xalan.jar) that returns lists of
coordinates to the browser client.

So when the client receives a list of point coordinates, it loops
through and adds markers like this: 

for (var i = 0; i < pointsCoordsArray.length; i += 3) {
  x = pointsCoordsArray[i];
  y = pointsCoordsArray[i + 1];
  marker = new OpenLayers.Marker(new OpenLayers.LonLat(x, y),
icon.clone());
  markersLayer.addMarker(marker);          
}

The loop steps by 3 because the point format is lat,lon,altitude.

What I'd like to do is also add a popup for each marker.  I tried
registering a marker mousedown event that would show a popup for
attributes of the marker, but it only shows the attributes for one of
the markers: 

marker.events.register("mousedown", marker, mousedown);

I know many of you have grappled with similar popup problems; I've seen
many posts about popups.  Please, do you have any advice on how to do
this?

Many thanks.

This isn't the useful part of the code. The part of the code that
matters is what is *in* the mousedown function. My guess is that it
refers to a variable ('marker') rather than the bound marker object
('this'), but there's no really any way of knowing with the code you've
provided.

For now, it looks like this: 

function mousedown(evt) {
  alert(marker.lonlat);
}

Not sure how to pass the specifically bound marker object to the
function.

This isn't the useful part of the code. The part of the code that
matters is what is *in* the mousedown function. My guess is that it
refers to a variable ('marker') rather than the bound marker object
('this'), but there's no really any way of knowing with the code you've
provided.

Don't use 'marker'. Use 'this'.

Hi everyone.
I'm a bit confused about spherical mercator property...

In the relative example from dev/examples, the SM is set for all the
layers, except the OSM ones. Why? I thought that both OSM and Google
use the Spherical Mercator. I think I've misunderstood it's effect,
when both Projection and DisplayProjection options are also set in the
map options...
In other words: what is reprojected relatively to what?

Thanks for any clarification...

sphericalMercator is a way of saying "This API works, natively, in
lat/lon, but uses raster images based in spherical mercator." It only
makes sense when using a commercial/third party API for which this is
true: all the 'native tile access' mechanisms don't need this flag.

OpenStreetMap data is accessed directly as tiles, so we don't need to
use the flag for it.

The configuration that matters for OSM is the map configuration options,
defined as var options = {} above.

Message-ID: <ae9185aa0804161318n5aa7ea4dmbe8091b1f76d33ac@mail.gmail.com>

Is it possible to modify a layer's url after it has been added to a
map with map.addLayer()? And similarly, is it possible to dynamically
alter a layer's params?

The things that I am trying to do are:
1. Pass a filter to a MapServer layer, e.g. filter=(id=123)
2. Dynamically change the MapServer layer(s) that comprise an OL layer.

If there is a better way to accomplish these things I'm all ears.

Thanks,

Hi all: Figured I'd share an OL powered site we've got going.

  http://www.dnr.state.mn.us/maps/compass.html 

It's a simple viewer but OL was perfect for this type of thing for us. It's using:

  - OpenLayers 2.5
  - MapServer 5.1 (development version, AGG backend)
  - TileCache 2 (mod_python, WMS layer)

We still see the odd clipping problem with road shields, even with metatiling on but for the most it
works well.

Yeah; I do it all the time. Use mergeNewParams()

l = layers['storms'];
l.mergeNewParams(date:'20080414', time:1530);

I don't think that a l.reload() would even be necessary. I think that 
mergeNewParams() calls reload.

Are you using a mapscript or WMS backend? Either way, setting the size
of your label_cache_edge_buffer to something higher than it currently is
will help you here: metaBuffer (default 10) plus 10 should probably do
it (the default is memtaBuffer + 5 with the mapscript layer)...

Great looking site though! Care to do a case-study like writeup on why
you chose this stack?

I remembered the labelcache_map_edge_buffer a second after I hit send. I started with
with MapServer layer but ran into some problematic memory leaks that seem to be caused
by a weird combination of platform/python/mapserver/tilecache. The MapServer tile cache
layer sets that for you and wms does not. So, I'm re-populating the cache right now.

(BTW it would be useful to have an option to force re-rendering of tiles when seeding.)

Would be happy to write something up. Is there an example someplace?

Thank you Christopher. Now it's clear... the use of the property is an
information for "the others", not for the layer where it is setted
Anyway I'm not sure of having unserstood what you've said about
"native tile access": is it a prerogative of tiling to be already
projected in the right way? Mmm... I think I miss something :-)

I am creating a selection box with a Shift-Mouse control and using this as a
BBox criteria to do a getfeatureInfo request. That works just fine. I also
draw the box on a vector layer and that is fine as well.

However, when you pan up and down the select box ?floats? relative to the
base map. Has anyone seen this and if so is there a workaround?

If this is new I will make a little test app.

You're using a Handler.Box, I assume? How are you getting this to stay
on the map? every implementation I know of, it disappears when you let
go. 

In general, controls are stationary: if you want something to stick on
the map, you're going to need to draw it in some other way than as a
control, because it needs to be in the viewport div in order to move
with the map. The best way to do this is probably via a temporary vector
layer, since this will correctly handle things like map zooms, drags,
etc.

Chris,

You are correct. I am using a Handle.Box control and the loX, LoY, HiX, HiY
is available which I then simply use to draw into a temporary vector layer.

This leaves me with a blue box over the area I selected.

So I am already doing as you suggest I believe. My snippet of code is as
follows:

//set up the getfeature info alert on shift mouse box select
control = new OpenLayers.Control();
OpenLayers.Util.extend(control,
	{
		draw: function ()
		{
			// this Handler.Box will intercept the shift-mousedown before
Control.MouseDefault gets to see it
			this.box = new OpenLayers.Handler.Box( control, {"done":
this.notice},{keyMask: OpenLayers.Handler.MOD_SHIFT});
			this.box.activate();
		},	notice: function (bounds)
			{
				removeCreateVectors() 	// this will clear out any previous vectors

// use the shift mouse control to drag a box and now get the coords of box
				ll = map.getLonLatFromPixel(new OpenLayers.Pixel(bounds.left,
bounds.bottom));
				ur = map.getLonLatFromPixel(new OpenLayers.Pixel(bounds.right,
bounds.top));
				centX = (bounds.left + bounds.right)/2
				centY = (bounds.bottom + bounds.top)/2
				var loX = ll.lon.toFixed(12);
				var loY = ll.lat.toFixed(12);
				var hiX = ur.lon.toFixed(12);
				var hiY = ur.lat.toFixed(12);
				BBox = loX+","+loY+"%20"+ hiX+ ","+hiY;   // used in GFI request

				// OK now draw out the drag box as vectors
				drawSelectBox(loX,loY,hiX,hiY) 	// this just draws a box
		}
	});
	map.addControl(control);

However, after I have finished doing what I want any vertical pan movement
'floats' the vectors relative to the base map and the selected features.

Cheers,

Brad Spencer

FWIW: what we do in MapFish is send the x,y position on each click to
the server, have the server do the intersection work and send a
GeoJSON representation of the matching features. Yes, this is one Ajax
request per click, but performance is good enough in general.

Hi all.

 

As in one of my previous post on this list I experienced problem wrapping
the dateline for a Tilecache layer. In practice the column of tiles
eastwards to the 180 latitude was calling a not existent 004 folder into the
level 02 of the tilcecahc hierarchy. The level 02 has only 4 subfolders,
from 000 to 003.

 

I tried to understand where the error was generated but I didn't find it.
For now I changed the getURL function into the OpenLayers.Layer.TileCache
to:

 

getURL: function(bounds) {

        var res = this.map.getResolution();

        var bbox = this.maxExtent;

        var size = this.tileSize;

        var tileX = Math.round((bounds.left - bbox.left) / (res * size.w));

        var tileY = Math.round((bounds.bottom - bbox.bottom) / (res *
size.h));

        var tileZ = this.map.zoom;

        /**

         * number - {Int} 

         * length - {Int} 

         *

         * Returns:

         * {String} A zero-padded string

         */

        function zeroPad(number, length) {

            number = String(number);

            var zeros = [];

            for(var i=0; i<length; ++i) {

                zeros.push('0');

            }

            return zeros.join('').substring(0, length - number.length) +
number;

        }

        var corrX = zeroPad((parseInt(tileX) % 1000), 3);

        if(corrX== '004'){

                corrX= '000'

        }

        var components = [

            this.layername,

            zeroPad(tileZ, 2),

            zeroPad(parseInt(tileX / 1000000), 3),

            zeroPad((parseInt(tileX / 1000) % 1000), 3),

            corrX,

            zeroPad(parseInt(tileY / 1000000), 3),

            zeroPad((parseInt(tileY / 1000) % 1000), 3),

            zeroPad((parseInt(tileY) % 1000), 3) + '.' + this.extension

        ];

        var path = components.join('/'); 

        var url = this.url;

        if (url instanceof Array) {

            url = this.selectUrl(path, url);

        }

        url = (url.charAt(url.length - 1) == '/') ? url : url + '/';

        return url + path;

    },

 

This solved my problem for now but I know that is not the best way to solve
the problems. Is there anybody with a better knowledge of OL than me that
experienced the same malfucntioning and managed to solve it in a better way?

 

Thanks

Hi Shipra,

we've just finished a (tiled) map based on OpenStreetmap-data and had 
about the same problems as you mention. I thought it would be helpfull 
to others to share some experiences:

Those labeling doubles/partials are 'known' problems, of which there are 
a lot of solutions. But it's not very obvious, because there are so much 
variables: type of geometries, tools used, label positions, edges etc
So there are a lot of buttons you can turn on to get the best result. 
It's part of the game to fiddle with those :-)	

Assuming you use some 'tiling'-mechanism, for example using Mapserver 
and Tilecache, there are the following issues:

- raster vs vector data
The problems you mention only appear if you render vector data (just to 
be clear). The actual problem is LABELING.
It has also to be clear that because of tiling you cut up your big-image 
in rather small mini-maps. The problem is that a renderer/mapserver will 
use only the information it has for current tile/mapimage to determine 
which labels to draw. This makes these 'edgy problems'.


DOUBLES and PARTIALS:

- labeling points versus area/polygons and automatic labeling
It good to realize yourself that there is a difference between labeling 
point geometries versus area/polygons. With the latter, you renderer (eg 
mapserver) is free to choose WHERE to put the label. It searches for the 
best position based on eg: available space around (edges), other labels 
in the neighborhood. The same for lines.
With points however the renderer does not have that much 'freedom'. If 
you use POSITION auto, it does have some, but if you lock it by giving 
POSITION the value 'cc', you force the label on one place.

It's this knowledge you can use to choose for example that you will use 
a point-layer for you labels (eg to generate a special point-label-layer 
from an polygon layer by generating a layer with the centerpoints of the 
polygons). In the case of using tiling: to 'fix' your (point)-labels by 
using cc for POSITION. But this is not enough to be sure there will be 
no doubles in your tiles. If you do not force the renderer to only draw 
whole labels (on the edges), you can end up with a partial label on the 
edge because the point is laying on the edge of one tile (but on this 
tile the label is only drawn half) and on the neighborhood tile nothing 
is drawn, because this tile is not aware of the point (and it's label).
So use PARTIALS=false to be sure you will end up with partials on tile 
edges.

Another option you can use here is the
	"labelcache_map_edge_buffer"    "-100"
configuration (in the metabuffer of the MAP FILE NOT THE LAYER!)
This makes that there will be a label-less border of 100 pixels in your 
map-image/tile ...
But what about those points laying on just 2 pixels from the edge of a 
tile? These will never be drawn then. That's where the Tilecache 
configuration 'metaBuffer' kicks in. If you use the metaTile=true option 
for tilecache, tilecache will not do 'tile by tile'-requests, but will 
request for example a 'metaTile' of 5x5 tiles at once. If you now use 
the option
	metaBuffer=100
for your metaTiles, it will request big tiles with a 100 pixel wide 
buffer around it. And just cut of this 100 pixel wide labelless(!) 
buffer for you, and all labels will be shown :-)

be aware of the option FORCE for you labels also. While it's not nice to 
have overlapping labels, you sometimes are 'forced' to use FORCE just 
because otherwise there will not be enough labels in your tiles... But 
be careful with 'FORCE true'...

- multiple labels / too much label for line/polygons
The labeling of lines and polygons is very different from the points, 
because mapserver has so much freedom to place the labels along the line 
or in the (big) polygons.
Because the map is divided in so much tiles/mini-maps, you will end up 
with too much labels for the same lines. This is why you really have to 
use metaTiling for your tilecache! Otherwise the 
labeling-buffer/mindistance/featuresize is determined for one minitile 
... which is not what you want probably...

So, be sure to put on metatiling, and fiddle around with the following 
label options then:
	mindistance (do no draw the same label within certain distance
	minfeaturesize (only put labels on features of a certain size)
	buffer	(do not draw labels in a certain buffer around current)
	partials (do or do not draw partials (on the edges)

Sometimes you have to split up the labeling in different scales, because 
at higher levels you want less labels to be seen etc.

Here some other links:

http://mapserver.gis.umn.edu/docs/reference/mapfile the label part:
http://mapserver.gis.umn.edu/docs/reference/mapfile/label

http://biometry.gis.umn.edu/tutorial/ has a nice part about labeling:
http://biometry.gis.umn.edu/tutorial/example1-4.html

And the config names:

MAPSERVER:

web
	metadata
		...
		"labelcache_map_edge_buffer"    "-100"
	end
end
..
	...
class
...
   Label
	...
	partials (false or true)
	buffer (4 number)
	force (false or true)
	position (cc .. )
	mindistance (100 )
	minfeaturesize (50)
	(angle)
   end
..


TILECACHE:

[layerx]
metaTile=true
metaBuffer=10


Mmm, ended up with al long email, hope this helps for somebody.
Maybe it's an idea to put this kind of info in a nice (illustrated) wiki 
article?

Regards and fiddle around,

Richard Duivenvoorde

Message-ID: <48071E8D.60902@camptocamp.com>

Dear Lists,

doing OpenLayers and MapFish project with a growing team of coworkers
and users, we came to the question: how to involve new staff fast and
efficient in the project.

The learning method, trying by yourself and studying examples is
possible, but leads to ask yourself and resolve problems already solved.

So we think, a wiki page that contains best practices would be useful.

I started a draft page, that will contain central information for
MapFish project. This page will contain display tips, map server tips,
caching tips, database tips, infrastructure tips and so on as everything
is related.

I would like to know, if you would find an interest to put on OL wiki,
OL specific best practices. The 2 pages would then be linked for easy
access to all the information. Help in maintaining this wiki page would
be nice.

See http://trac.mapfish.org/trac/mapfish/wiki/HowToOptimize

Best regards,

Emmanuel

Are you using Google Maps as a baselayer, and not using
sphericalMercator ? (Also, you didn't provie the code to drawSelectBox,
so I can't actually tell *what* you're doing. :))

Hello everybody,
during my learning with OL and TileCache I find this strange issue:

http://doktoreas.dyndns.biz/apache2-default/luca/ol/wms_tilecache.html

As you can see, also if both layers use the same TileCache layer they appear 
differentes and, looking at the coordinates, just the first one is correct.
This is the layer:

[nasajpl2]
type=WMS
url=http://localhost/cgi-bin/wmsdata
layers=nasa
bbox=180000,4600000,400000,4870000
srs=EPSG:23033
maxResolution=1132.8125
extension=jpeg
debug=true
size=512,512

What am I doing wrong?

Thank you very much
Luca

First of all, you haven't told OpenLayers about your changed tile size.
The fact that this works is more of a coincidence than anything else.

Two, there's probably no reason to use a Layer.TileCache here? 

Three, I'm not 100% sure that Layer.TileCache owrks in different
projections (though I think we fixed that with 2.6).

Hi,

 

Just installed the 2.6 release live tonight and did all my testing in FF
using firebug and was happy. Then decided to crank up IE7 and noticed
that in my page the hyperlinks I created inside the FramedCloud do not
work with IE, they are fine in FF and I cannot for the live of me see
why. A page showing the error is as follows -
http://www.exploroz.com/Places/78655/WA/Old_Point_Cloates_Lighthouse_Rui
ns.aspx try clicking on the Diving Directions or Maps & Books links in
IE and they just do nothing - FF works fine. Any ideas?

PS: I have firbug loaded you just need to add ?FB=1 to the address line
to have it load in however I have been unable to make lite work with IE
maybe another problem if anyone has an idea on this one also?

Subject: [OpenLayers-Users] OpenLayers 2.6 tileloaded event
Message-ID: <4807729E.9060108@refractions.net>

First, thanks to everyone who has contributed to the 2.6 release.

My question is related to the The Layer Load Monitoring Example: 
http://openlayers.org/dev/examples/layerLoadMonitoring.html

In OpenLayers 2.5 this example displays the following log with each tile loaded generating a log event:
(8:38:42) WMS Buffer 0: Load Start
(8:38:43) WMS Buffer 0: Tile loaded. 8 left.
(8:38:43) WMS Buffer 0: Tile loaded. 7 left.
(8:38:43) WMS Buffer 0: Tile loaded. 6 left.
(8:38:43) WMS Buffer 0: Tile loaded. 5 left.
(8:38:43) WMS Buffer 0: Tile loaded. 4 left.
(8:38:43) WMS Buffer 0: Tile loaded. 3 left.
(8:38:44) WMS Buffer 0: Tile loaded. 2 left.
(8:38:44) WMS Buffer 0: Tile loaded. 1 left.
(8:38:44) WMS Buffer 0: Tile loaded. 0 left.
(8:38:44) WMS Buffer 0: Load End. Grid:3x3

However, OpenLayers 2.6 only generates the Load Start and Load End events, nothing for the loading 
events associated with each tile:
(8:39:45) WMS Buffer 0: Load Start
(8:39:47) WMS Buffer 0: Load End. Grid:3x3

Previously we were using the tileloaded event to inform users of how many tiles were remaining to be 
loaded.  Has this event changed in OpenLayers 2.6?  Is there some other event or method I should be 
using to provide a similar status to users?

Thanks,
Emily

 From my perspective as a struggling user, this is a GREAT idea! I will 
be happy to contribute to maintenance, and eventually to content, 
although at the moment I think my practices are better characterized as 
"worst" rather than "best".

Along this same line of thought, I am wondering why OpenLayers doesn't 
have a Documentation Team (distinct from the developers). There is a 
need to provide more help to the lower-level users, and documentation 
written by the developer tends to be difficult for these users because 
the developer is so familiar with the application that they tend to 
leave out or gloss over a lot of details that are obvious to them, but 
not to the rest of us.

Because you haven't started one yet :) Are you looking to manage the
Documentation team? What tools are you missing?

Sure, no problem. You can find it at:

  http://maps.dnr.state.mn.us/compass/compass_sample.map 

Things to note:

  - I use includes heavily so this file is the result of serializing a much simpler map file which is why 
you'll see scientific notation for some numbers and particularly verbose layer descriptions.

  - As mentioned in a follow-up by Chris, setting labelcache_map_edge_buffer eliminates shield getting
cut off. I had started with a TileCache MapServer layer which set that automatically and then switched
to a WMSLayer which doesn't. Setting explicitly fixed any issues.

  - I'm using the dev version of MapServer which introduces a new label processing option. If you see a
line like "PROCESSING "LABEL_NO_CLIP=1" it is telling MapServer to compute a label point before clipping
the feature. This results in stable label positions for polygon and line features (but is most useful with 
polygons). I'm just experimenting with it by fixing label positions, but it's another tool to help deal with edge
labeling issues.

  - in order to create as small of tiles as possible I'm forcing AGG output through a pre-computed palette.
The results are dramatic in terms of file size. I'm not able to achieve Goggle-sized tiles but that's to be
expected since the maps contain far more information. The trick was to render a large sample 24-bit 
sample image (http://maps/compass/compass_color_sample.png) and generate a 8-bit palette from it. I
used Photoshop in this case.

Several of us, have made efforts to add more docs in the form of "User
Recipes" ( How someone has accomplished a task ) which is found under
the both "User" and "Developers" headings on
http://trac.openlayers.org/

The thought was to make the recipes a narrative of the code, unlike the
examples which are typically sparse in their comments and more exactly
can be found at
http://trac.openlayers.org/wiki/UserRecipes


Then another effort was to catalog the different projects (maybe a
better name can be found) that are under development,
http://trac.openlayers.org/wiki/ProjectsUnderDev

That page does have a Documentation with an ongoing effort on how to
optimize OL  and hopefully more content in the future.

Message-ID: <4807F3C2.9030604@inetnebr.com>

Creating large tile sets is sometimes a technical burden.. (particularly 
if you are not able to use tilecache)
 what I am interested  in.. is merging tile sets. by using different 
layers Is it possible to define a layer as
 being offset from the basic map definition The map goes from 0 to 30000 
wide and 0 to 30000 high
but has 4 tilesets.. each generated as  15000 x 15000 ...can I offset 
these layers
ie.
[0 to 15000] [0 to 15000 ] 
[0 to 15000] [15000 to 30000] 
[15000 to 30000] [0 to 15000 ]
[15000 to 3000] [1500 to 30000]

Will I need ot use pngs (ie something with transparency or could I get 
away with jpegs
for the main images and pngs for areas outside the area of data..  what 
about the border
cases?

This looks like a bug. Thanks for the good report with straightforward link,

Do you have a trac account, could you turn this into a ticket for 2.7?

Erik,

 

I am a little miffed as I was able to make the exact same code work on a
page that is almost exactly the same. It is really strange however I
think I have isolated the issue to a problem somewhere between prototype
1.6.0.2 and Openlayers 2.6. Because when I pull the prototype library
from the page the hyperlinks seem to work, mind you one page I do not
have to pull the prototype library and it works (WEIRD). I am still
investigating and will report more when I get to the bottom of the
issue. As you can understand it is very annoying when two script
libraries clash and cause some weird error.

 

Is using prototype with OL a problem? I have some AJAX code that can be
called from every page of my site and I used the prototype library to
support this, coupled with using the element features of prototype,
would it be better to change my base scripts to use OpenLayers classes?

 

I do not have a trac account as yet. I have loaded patches (Right Mouse
support) to Trac using the Openlayers user. I have completed the
agreement and sent it in. Is there more I need to do for a Trac user?

Subject: [OpenLayers-Users]  wfs cacheing
Message-ID: <16763389.post@talk.nabble.com>


Hi,

I am using OpenLayers to download features from a wfs server.  Currently
OpenLayers refreshed the wfs server whenever you move beyond the extents of
the data.  If you then move back in to a part of the map which previously
had features already downloaded it refreshes.  Is there a way to cache wfs
returns on the browser so that it does not have to redownload areas already
covered?

Thanks.

HI,

 

After a whole day of playing with this I am still at a loss. I have
worked out that the problem only occurs when the prototype 1.6.0.2 is
used along side of Open Layers. I cannot get anything out of Firebug
Lite on IE to help me as the event just does not seem to trigger mind
you the status bar reflects the href in the link when you hover over the
link alas it appears that the mouse click event just goes away in IE.
The mouse click is active on the close box just not the contents of the
popup - which is clearly shown in the source code of the page (it is
loaded statically when the page is drawn and not an RSS) so you can
check that the syntax is valid.

 

Would the load order of prototype and OL make any difference?

 

If anyone can assist their are two links I can offer showing the same
issue (mid you there are nearly 80,000 pages effected):

http://www.exploroz.com/Customers/Custom_Boat_Loaders.aspx - Click on
the image on the map to open the popup and see if you can click

http://www.exploroz.com/Places/28159/NT/Ayers_Rock_Uluru.aspx - The
popup will fire up automatically

 

OT NOTE: You will also note that I have completely rebuilt my
topographic Australian base maps using mapserver's new AGG graphics and
used some information I gained from Steve Lime's demo site with it's
nice colour pallet outputformat - makes the png's very small.

OpenLayers does not have this functionality at this time.

This is a bug/regression, created by
http://trac.openlayers.org/changeset/6832/trunk/openlayers/lib/OpenLayers/Events.js .

While we work out the correct resolution to this issue, you can use the
following workaround:

Pass an "EVENT_TYPES" property to Layer options, as such:

    buffer = new OpenLayers.Layer.WMS( "WMS Buffer 0",
            "http://labs.metacarta.com/wms/vmap0",
            {layers: 'basic'} ,
            {EVENT_TYPES:["loadstart", "loadend", "loadcancel",
                          "visibilitychanged","tileloaded"]}
    );

Note the inclusion of the 'tileloaded' event. 

I'm sorry about this regression.

Subject: [OpenLayers-Users]  Can not register dblclick in a point handler
Message-ID: <16764014.post@talk.nabble.com>


All,

Using OL 2.5, I would like to write a Control inherit from
OpenLayers.Control and register the dblclick but I can not get it work. When
I double-click the map the callback method for dblclick never get called. So
just wonder if I did anything wrong. Here is initialize code of the control

initialize: function(layer, options) {
     	OpenLayers.Control.prototype.initialize.apply(this, [options]);
     	this.handler = new OpenLayers.Handler.Point(	
     		this,
            {dblclick: this.reverseGeocode}
        );
       this.handler.activate();
} 

Thanks

Thanks! A minor correction for the archive, the parameter list must be within {}
    l.mergeNewParams( {date:'20080414', time:1530} ;

BY way of update on this issue - I have worked around it now by making a
number of page adjustments and only loading prototype on pages that do
not have OL maps installed. This seems to have worked around the error
and I will try to investigate some more is due course. It is strange to
say the least as the two libraries should work together without issue. I
have not been able to determine which library is causing the problem
because it is so strange.

 

Anyway just wanted to let you all know because if you visit the pages I
have mentioned below the error will not show itself.

HI,

 

After a whole day of playing with this I am still at a loss. I have
worked out that the problem only occurs when the prototype 1.6.0.2 is
used along side of Open Layers. I cannot get anything out of Firebug
Lite on IE to help me as the event just does not seem to trigger mind
you the status bar reflects the href in the link when you hover over the
link alas it appears that the mouse click event just goes away in IE.
The mouse click is active on the close box just not the contents of the
popup - which is clearly shown in the source code of the page (it is
loaded statically when the page is drawn and not an RSS) so you can
check that the syntax is valid.

 

Would the load order of prototype and OL make any difference?

 

If anyone can assist their are two links I can offer showing the same
issue (mid you there are nearly 80,000 pages effected):

http://www.exploroz.com/Customers/Custom_Boat_Loaders.aspx - Click on
the image on the map to open the popup and see if you can click

http://www.exploroz.com/Places/28159/NT/Ayers_Rock_Uluru.aspx - The
popup will fire up automatically

 

OT NOTE: You will also note that I have completely rebuilt my
topographic Australian base maps using mapserver's new AGG graphics and
used some information I gained from Steve Lime's demo site with it's
nice colour pallet outputformat - makes the png's very small.

Erik,

 

I am a little miffed as I was able to make the exact same code work on a
page that is almost exactly the same. It is really strange however I
think I have isolated the issue to a problem somewhere between prototype
1.6.0.2 and Openlayers 2.6. Because when I pull the prototype library
from the page the hyperlinks seem to work, mind you one page I do not
have to pull the prototype library and it works (WEIRD). I am still
investigating and will report more when I get to the bottom of the
issue. As you can understand it is very annoying when two script
libraries clash and cause some weird error.

 

Is using prototype with OL a problem? I have some AJAX code that can be
called from every page of my site and I used the prototype library to
support this, coupled with using the element features of prototype,
would it be better to change my base scripts to use OpenLayers classes?

 

I do not have a trac account as yet. I have loaded patches (Right Mouse
support) to Trac using the Openlayers user. I have completed the
agreement and sent it in. Is there more I need to do for a Trac user?

I can confirm that these links are *not* clickable in ie6 and yet *are*
clickable in ff.

 

This looks like a bug. Thanks for the good report with straightforward
link, David. 

 

Do you have a trac account, could you turn this into a ticket for 2.7?

 

Thanks!

Erik

PS: I have firbug loaded you just need to add ?FB=1 to the address line

Message-ID: <480B5FEE.1020904@gmail.com>

Hi list,

I have a little OL application showing data in utm33-wgs84 (epsg: 32633) 
and I'm using a separate div to display the mouse position in 32633 with 
no problems.

What I'd like to do is to display the mouse position also in 
geographical wgs84 (epsg: 4326) in another different div.
In this way users could see both 32633 and 4326 coordinates at the same 
time.

Is it possible?

thx

You should use the click handler as opposed to the point handler. See

Subject: [OpenLayers-Users] Intercept mouse click using Navigation control
Message-ID: <20080420212831.51848A70A1@server42.ukservers.net>

Hi
A question from a newcomer who doesn't know what he is doing yet.
I wish to intercept mouse clicks on the map and found examples of how to
achieve this using OpenLayers.Control.MouseDefaults in the list archive. I
have got this working ok using code of the form:

olMouseDefaults = new OpenLayers.Control.MouseDefaults();
olMouseDefaults.defaultClick = function(evt) {
  var point = this.map.getLonLatFromViewPortPx( evt.xy );
  alert("Got point:" + point);
  OpenLayers.Event.stop(evt);
  return false;
}  
map.addControl(olMouseDefaults); 

Unfortunately I now see from the source of MouseDefaults.js that this
control is now deprecated and I should be using the Navigation control.  I
cannot find any examples of how to achieve click interception using this
control and my attempts have all failed.

Help would be gratefully received.

Hi Ale,
you could use the OpenLayers.Projection.transform(point,source,dest)
method, based on proj4js :

Subject: [OpenLayers-Users] Calculate the scale of the map in a printing size
Message-ID: <5b629bbf0804210016x5f628dceh2cabf9022c4fd4e9@mail.gmail.com>

Hi everybody,

I'm not sure if this mailing is the right place to ask, so If this is the
not the right one, please point me a proper list to do it.

I'm developing a printing system in PHP Mapscript, and I'm dealing with the
well known "symbols and fonts size after resizing the map" problem. I've
researched in different mailing list, but I didn't find a working solution.
Someone pointed that it might be possible to automatically look for mapfile
elements and resize them with Mapscript. I'm working on this approach.

With this approach I'm getting good results. But now, I need to calculate
the scale of the map in 2 different sizes: 1) the scale of the map with the
viewport's size, and 2) the scale of the map with the printing size.

With OpenLayers, the scale at viewport's size is not problem, once I can get
this value with map.getScale(). But, how do I calculate the scale of the
same map, but with a different size?

To make it easy to understand, let's suppose I have a 800x600 map viewport,
and I wanna print this same map with 288 dpi. Since 72dpi is the base value
of mapserver, 288dpi = 4 * 72 dpi. So the printing size will be 800*4 x
600*4 = 3200 x 2400. The basic scale value I can get from map.getScale().
But how do I calculate the scale of this map with a 3200 x 2400 size?

I need to work with this value in Mapscript so the symbols and fonts can be
properly resized at different sizes/resolutions. The value will be around
map.getScale() / 4, but this is not the precise value, and it could lead to
some precision errors.

thanks in advance,

Pedro Simonetti.

Hi folks,

I am writing a web application using MySQL/OpenLayers/AJAX/PHP; this app
must enable some users to draw a vector shape and then import it in a
Spatial-aware MySQL database.

Now, everything is theoretically fine, till I have to put the actual
polygonal data in the database; 'cause I use for this the WKT format
exported string, but the resulting string is calculated on the Google base
layer projection (EPSG:900913).

That won't do, because my database holds data in UTM33S projection
(EPSG:32733), and I want data to be consistent among already existing
pre-defined shapes.

Is there a way to force the point coordinates to show up in the other EPSG
projection, so I can put them directly in the DB with a single and
straightforward query (obviously without performing boring string parsing
and coord conversion routines)?

Formats all have an internal (feature) and external (string) projection
options, passed at create time. These options allow you to specify
projection objects, which are used to change the coordinates when
reading/writing. 

You will need the support of a library which can transform from
EPSG:900913 to EPSG:32733 correctly. proj4js may be able to do this; I
don't know for sure.

text layer?

Message-ID: <480CAF23.4000901@oit.state.nj.us>

Hi All-

I know this doesn't pertain directly to OpenLayers, but hopefully this 
will be of help to someone :) I just uploaded to the arcscripts 
repository [1] an ArcGIS geoprocessing python script that will iterate 
through all the features in a feature class (can be done in ArcMap or 
ArcCatalog) and exports a GeoJSON formatted text file. I used the 
GeoJSON draft version 6 [2] as the output format. It will also output 
either all or the specified attributes of that feature. You can even put 
it in model builder and do some preprocessing of the data (joining data, 
dissolving or simplifing features) before the export.

I needed a way to empower folks in different agencies to test their 
vector data with OpenLayers without having to setup multiple, one-off 
webservices/mapservices just for development purposes. I've got to admit 
that this was selfishly motivated (not wanting to be bothered by a 
multitude of individual requests), so if anyone out there can also 
derive some benefit from this, it would make me feel better :)

If there are any bugs/improvements that people come up with, please let 
me know.

Subject: [OpenLayers-Users] Pan/zoom bug with IE7
Message-ID: <480CBBC2.3070801@geograf.dk>

I have been tracking an annoying bug in IE7 (FF2 and IE6 works).
When I pan (and sometimes when I zoom), the map stops displaying and 
interacting (the position freezes).
After some digging, it turns out that the map size suddenly reports 
itself incorrectly.
Sometimes it is 100x100 (because the style says w+h = 100%).
Other times, the width is correct, but clientHeight is 0.

Is this a known problem, or is there a known cause?
I'm using OpenLayers 2.5.

Subject: Custom Box handler conflict?
To: OpenLayers Users <users@openlayers.org>


I'm using the brand new 2.6 (well done guys!) but I haven't try with
 older versions, so...
 In my website I'm using OpenLayers and NavToolBar component, that
 implements a ZoomBox handler for a zoom rect funtion that works well.
 I've tried to add this custom components, taken from the openlayers
 samples, and i have a strange behavior:

 var customBox = new OpenLayers.Control();
    OpenLayers.Util.extend(customBox,
    {
        draw: function ()
        {
            this.box = new OpenLayers.Handler.Box(customBox,
                { "done": this.notice },
                { keyMask: OpenLayers.Handler.MOD_SHIFT });
            this.box.activate();
        },

        notice: function (bounds)
        {
            var ll = map.getLonLatFromPixel(new
 OpenLayers.Pixel(bounds.left, bounds.bottom));
            var ur = map.getLonLatFromPixel(new
 OpenLayers.Pixel(bounds.right, bounds.top));
            alert(ll.lon.toFixed(4) + ", " +
                ll.lat.toFixed(4) + ", " +
                ur.lon.toFixed(4) + ", " +
                ur.lat.toFixed(4));
        }
    });


 If i add this component to the map, when i try the code all works well:
 the navtoolbar is in "pan" state so i could pan the map as usual, and
 using shift i could drag a zoombox and show the bounding box
 coordinates.
 If i select the zoomrect tool from navtoolbar i lost the behavior of
 the custom component :(
 Any try to use shift + zoombox generates the behavior of the zoomrect tool.
 any suggestion?

Generally, the answer is 'no, and why are you still using a Layer.Text?
Use a Layer.GML with a format: OpenLayers.Format.Text and a
selectFeature control instead.' 

I understand that this is impractical for long running applications (we
maintain backwards API compatibility for a reason, after all). 

Anyway, the following hacks will let you get something that I like a lot
better for text layers:

        OpenLayers.Feature.prototype.popupClass = OpenLayers.Popup.FramedCloud;

        OpenLayers.Layer.Text.prototype.markerClick = function(evt) {
            var sameMarkerClicked = (this == this.layer.selectedFeature);
            if (this.popup) {
                this.popup.toggle(); 
            } else {
                this.layer.map.addPopup(this.createPopup(true));
            }
            this.layer.selectedFeature = (!sameMarkerClicked) ? this :
null;
            OpenLayers.Event.stop(evt);        
        }

Good Luck,

This example: http://openlayers.org/dev/examples/spherical-mercator.html
uses the displayProjection control to convert the 900913 coordinates
used internally to the normal lat/lon 4326 ones.

Hi Diego,

I managed to do what you want to do by implementing my own version of
the NavToolBar class. See the attached patch to
examples/navtoolbar.html to understand what I did.

Hope that helps,

Hello

You should use OpenLayers 2.6 and its click handler for intercepting
clicks on the map. See the click-handler.html example to understand
how to build a control based on that click handler.

I've applied your parth but I have still some problems.
Actually, I've done the same work in my code, but I've not used
customBox.activate()...
Now, with your patch, the behavior is correct if i select the zoomrect
tool in the toolbar.
If i select pan tool I have this behavior:
1) at start, in pan status BEFORE selecting zoomrect status, the
custombox works well (i.e. rect + alert using shift, pan without
shift).
2) in pan status AFTER selecting zoomrect status, the custombox works
as pan, but if i press shift i don't see the alert but the component
work as zoomrect.
You could verify if in your code this behavior happens, or maybe I've
made some other mistake?

Hi Eric

Unfortunately I am actually using UK Ordnanace Survey OpenSpace mapping
system (http://openspace.ordnancesurvey.co.uk) which is based on OpenLayers
2.5.  Probably I should just stick with what I have got (which works ok) and
move to the later technique when OpenSpace upgrades.

I had not previously found the examples (though I see now that they are
referenced on the OpenLayers front page). I had been wading through the
documentation which is a trifle heavy going.  Even though the examples may
assume the latest version of OpenLayers I can see that they will be very
useful.

Thanks for your help
Colin

I've checked the navigation control (that is used in pan status) and
actually it defines a zoombox that is used when the user press SHIFT
button... so the behavior is correct.
Thanks for the support.

Subject: [OpenLayers-Users]  deCarta DDS?
Message-ID: <16824705.post@talk.nabble.com>


I would like to use OpenLayers for a project that uses deCarta's DDS as the
map server - the point would be to be able to swap out the map server
without affecting the higher layers. I don't see an OpenLS layer in
OpenLayers. Even if there was one, I'm not sure how closely deCarta conforms
to the spec. 

Does anyone know of existing code I could use? 

I am also very open to advice about other possible approaches if this one
just doesn't make sense. 

Thank you,
Craig

Subject: [OpenLayers-Users] changes in wms between 2.4 and 2.6
In-Reply-To: <22011833.50251208880485217.JavaMail.root@mail.thehumanjourney.net>
Message-ID: <10404845.50401208880860226.JavaMail.root@mail.thehumanjourney.net>

Hi all,

I am wondering if there have been any changes in the way wms is handled between openlayers 2.4 and 2.6. I went to upgrade my site from one to the other, and found that my wms layers display in a different location, when all I've changed is the line that says to look in folder Openlayers-2.6 rather than 2.4 for the javascript.(I even downloaded a clean copy of 2.4 to check it wasn't any changes I had made). 

It looks like a projection issue- you can see the difference if you look at the following:

http://mapdata.thehumanjourney.net uses 2.4
http://mapdata.thehumanjourney.net/index_26.html uses 2.6

If you zoom in far enough to engage the wfs, then sites are in the correct location in both versions of the map.

Can anyone help me with this- or give me an idea how to debug it?

Many thanks

Jo

In 2.5, we turned the default 'reproject' option on WMS layers to
'false', because it offers a false sense of success in overlaying raster
layers of different projections which isn't really accurate.

Setting reproject: true should fix this issue for use now, but you
should really at some point look into using SphericalMercator:
http://crschmidt.net/~crschmidt/spherical_mercator.html explains some of
the how.

Hi list,

I am experimenting with transitioneffect resize and sometimes encounter

anyone? Using OL 2.6 and FF2.

Some more info, this seems to only happen when using fractionalZoom on 
the map, but it's quite hard to make a reproduceable test case.

Bart,

I've seen this too on occasion (with fractional zoom + transition 
effects), but I agree it's very difficult to reproduce.

You don't have a 'theme' directory alongside your OpenLayers.js / img/
directories.

Hi,
as explained I need to show the MousePosition coordinates values in epsg 
4326 even if my map is in epsg 32633.
Well, this topic seems aswer my needs.
http://www.nabble.com/How-to-change-displayProjection-for-MousePosition-Control-td16331163.html#a16340730

So, I tried to do the following:

1) First, I downloaded proj4js from svn and I added it in my page's header

<script src="OpenLayers-2.6/OpenLayers.js" type="text/javascript"></script>
<script scr="proj4js/lib/proj4js.js" type="text/javascript"></script>
<script scr="proj4js/lib/defs/EPSG32633.js" type="text/javascript"></script>
<script scr="proj4js/lib/defs/EPSG4326.js" type="text/javascript"></script>

the EPSG32633.js and EPSG4326.js files (not included in the downloaded 
package) contains, respectively, these strings:

Proj4js.defs["EPSG:32633"] = "+proj=utm +zone=33 +ellps=WGS84 +datum=WGS84 +units=m +no_defs ";

Proj4js.defs["EPSG:4326"] = "+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs ";


2) Then I added this code to my page

mp = new OpenLayers.Control.MousePosition();

	mp.displayProjection = new OpenLayers.Projection("EPSG:4326");

	map.addControl(mp);


but the displayed coordinates are always 32633...
may you help me to understand the problem?


thx, alessio

I'm assuming this is a typo?

With a full HTML example, probably someone could.

Hi,

I have a problem with the mousewheel.  When I zoom in and out it zooms by 2
steps instead of just one.  If I zoom in or out using the pan zoom bar it
only uses a single increment. Any ideas why this may be happening?

Thanks.

Could this be due to some "scroll three lines at a time" mouse setting
on your machine?

Try modifying the following mouse wheel related events.  I changed these
because I wanted the mouse wheel to zoom in using the centre of the map,
not centre at mouse cursor.

in Navigation.js:

    /** 
     * Method: wheelUp
     * User spun scroll wheel up
     * 
     * Parameters:
     * evt - {Event}
     */
    wheelUp: function(evt) {
        //this.wheelChange(evt, 1);
        this.map.zoomIn();
    },

    /** 
     * Method: wheelDown
     * User spun scroll wheel down
     * 
     * Parameters:
     * evt - {Event}
     */
    wheelDown: function(evt) {
        //this.wheelChange(evt, -1);
        this.map.zoomOut();
    },

in MouseDefaults.js:

    /** 
     * Method: defaultWheelUp
     * User spun scroll wheel up
     * 
     */
    defaultWheelUp: function(evt) {

//        }
         this.map.zoomIn();
    },

    /**

I have a problem with the mousewheel.  When I zoom in and out it zooms
by 2 steps instead of just one.  If I zoom in or out using the pan zoom
bar it only uses a single increment. Any ideas why this may be
happening?

Thanks.

Subject: [OpenLayers-Users] [Mapserver & OpenLayers] Repetition and drag of
	line with DB points.
Message-ID: <BLU120-W313B97EEE5C1C0AA98A953E9E30@phx.gbl>


Hi!

> I'm using OpenLayers to display a mapfile (so a file of Mapserver). 
I'm using Lambert II projection (EPSG:27582) and I obtained the following repetition, as you can see on at this URL: http://www.forumsig.org/attachment.php?attachmentid=2286&stc=1&d=1208951661
What can I do?

> Moreover, I have points in my DB and I would like to drag a line between these points. How can I do with OpenLayers?
I saw the example on the OL website but it draws a line with mouse clicks.

Thanks and excuse me for my english, I'm french!

Subject: [OpenLayers-Users] How do i add multiple GeoJson features to same
 layer
Message-ID: <16834653.post@talk.nabble.com>


Hi!
I save all my features (polygon/vector) in an BLOBfield as GeoJSON in may
DB.

Then i use some AJAX to load the data but it only adds the last feature.

I'm just using som simple modified examples from the exampelsite.

The function i use to deserialize the GEOJSON and add it to the map is this:
	function deserialize(element) {

            var type = "GeoJSON";
            var features = new OpenLayers.Format.GeoJSON().read(element);
            var bounds;
            if(features) {
                if(features.constructor != Array) {
                    features = [features];
                }
                for(var i=0; i<features.length; ++i) {
                    if (!bounds) {
                        bounds = features[i].geometry.getBounds();
                    } else {
                        bounds.extend(features[i].geometry.getBounds());
                    }

                }
                polygonLayer.addFeatures(features);
                map.zoomToExtent(bounds);
            } else {
                element.value = 'Bad input ' + type;
            }
        }

The GEJSON data that i recieved from db looks like:
{"type":"Feature", "id":"OpenLayers.Feature.Vector_153", "properties":{},
"geometry":{"type":"Polygon", "coordinates":[[[1914938.6508478164,

Subject: [OpenLayers-Users] Can't remove point feature OL 2.6
Message-ID: <13855887.post@talk.nabble.com>

Hi list,

I try to remove a point feature in OL 2.6. Line and polyline works OK in
FF2 and IE7.
"selectFeature" works OK in OL 2.5.
Removing the first point works but after then 
This code example is based on modify-feature.html OL 2.6.
What's wrong and how can I do this properly?

Regards,
Fred van Beelen BICT

Do you have two sets of Navigation (or MouseDefaults) controls defined
on the map?

Hi list,
with the precious suggestions of Giovanni Allegri I solved this issue!

There where two problems:

1) there were typos (as Chris said) in my code: various "scr" instead 
"src" linking the js scripts in the header... ahhaarg

2) it is mandatory to set Proj4js.libPath='proj4js/lib/'; in the init 
function to access to projCode/utm.js, that is needed to interpret UTM EPSGs

Hope this will be helpful for someone in future,

alessio

Note that you can also load the file lib/proj4js-compressed.js which 
includes all files required (or lib/proj4js-combined.js if you want to 
debug) and the libPath setting is not used.

Subject: [OpenLayers-Users] zoom level resolution in epsg:900913
Message-ID: <00c301c8a61b$80caa0b0$825fe210$@gadenz@jrc.it>

Hello!

 

has anybody calculated the resoluzion for zoomlevel for the epsg:900913.
What I intend to do is to use tiles for the first 10 zoom levels and then
call directly a wms server. I think the only way is to set the minResolution
parameter of the tiled layer equal to the maxResolution of the wms layer and
for having no overlap I think both the parameters have to be congruent with
the resolution of tiles of level 10. Am I right?

 

Is there any other way to do this? As far as I know there is not a
maxZoomLevel parameter, right?

 

Thanks

 

Simone

Has anyone loaded a simple KML/GML layer from a local text file?  Maybe
this is trivial ...

It may or may not be trivial, depending on your browser. FF2 allows you
to open files via file:/// via XMLHttpRequest. IE7, FF3 do not.

In general, local filesystem access via standard HTTP mechanisms is
going away, possibly due to the security risks that it creates (even
with the same origin policy): If you can't open a file on disk without
explicit user permissino from a webpage, the user is a lot safer in the
end.

Hi,
 
as a workaround i use a textarea, paste into it the contents of my KML and
then add it to the map. 
 
Likewise i use it to parse KML to fill a <select> element for places to
center. You can try it here:

Subject: [OpenLayers-Users]  WKT in MySQL
Message-ID: <16852122.post@talk.nabble.com>


Hi all,

I'd like some help on the following. I'm trying to get a table from my MySql
database that contains WKT formatted strings formed as (POLYGON((x1 y1,x2
y2,...,xn yn)) to show up on a vector feature map as polygons. I've inserted
the code below, using php to loop throught the table & create a polygon for
each line in the table. I'm getting ')' expected errors & i truly have no
idea what could be wrong. I've also inserted some of the generated code by
the php loop. Any pointers will be greatly appreciated.

thx
Pieter

Are you getting the ')' expected area from javascript or PHP?
Do you know approximately where (which line or from which function) the

Such information would greatly simplify helping you debug this.

ok so the problem is that you do not have your WKT enclosed in quotes. Thus
it is being read as if it is a javascript function and when it hits the
first comma in the WKT string, the javascript engine gets confused.
So wrap the WKT strings in quotes and it should.
Also, a hint for performance improvement when you do get it working, is to
only declare the features variable once and then reassign it's value, or to
just directly load them into the vector layer via:
vectors.addFeatures(WKT.read("A WKT string"));

Thanks for the info, my knowledge of javascript is rather limited atm. 

I've included the quotes (tried ", as well '), but now javascripts throws
that vectors is empty or not an object...

Is there a way to find out the line number in the actual html? As i can't
seem to relate the javascript error lines to the actual html.

Arnd,
This is a very interesting example, the application has really great response as well!  

However, I am having difficulty understanding where exactly the KML comes from originally, i.e., where is your source for your list of points of interest??

Thanks!

Hi,
 
as a workaround i use a textarea, paste into it the contents of my KML and
then add it to the map. 
 
Likewise i use it to parse KML to fill a <select> element for places to
center. You can try it here:

Has anyone loaded a simple KML/GML layer from a local text file?  Maybe this
is trivial ... 

 

Thanks!

Hi Robert,

I meant, you can paste your own KML (points only) into the Input textarea to
fill the select-element. In the toolbar click on the cogwheel and at the
bottom of the dialog you can open the textarea to do this.

The POIs are not a KML file, but a javascript array. I only offer with the
Input textarea to fill the select-element from KML and with the Output
textarea to generate KML from the select-element.

But in other applications I use this way to create features from KML. It is
easier to handle than to use a ajax-call, a proxy-script and upload a local
KML file.

Subject: [OpenLayers-Users] URL CENTER VAR
In-Reply-To: <16860148.post@talk.nabble.com>
References: <16860148.post@talk.nabble.com>

Add the OpenLayers.Control.ArgParser control and use the lat and lon
URL parameters to set the centre point on load.

If you want a default centre point without having to pass it in the
URL all the time, this code will work:
if(!map.getCenter()) map.setCenter(new OpenLayers.LonLat(-88.3,36.33))
(assuming that I have correctly interpreted your coordinates in the
example URL you gave)

Subject: [OpenLayers-Users] A little game with OL 2.5
Message-ID: <E1JpR7o-0002iS-00@smtp08.web.de>

Hi,

To explore the capabilities of OpenLayers I have build a litte game with OL
and Google Maps. It's a sample for vector drawing, retrieving Web Services
(geonames.org, Panoramio) and dragable windows.

Please have a look and hopefully enjoy the game.

Fred,

Would you mind being more specific on the issue you're having. I'm
having problem understanding what's bothering you.

Thanks,

No you don't, so your problem lies somewhere else.

Don't know exactly what fixed it, but they are on now.

You can check the result here

www.icoe.be/NW/PHP/LGEMap.php.

Now i can play around with the map, thanks a lot everyone for helping

One more question. Is there a way to make a vector layer visible all the
time? Right now, it disappears when you zoom out too much

cheers
Pieter

put the 'options' hash on your map instead of on your layer.

Subject: [OpenLayers-Users] Layer.clone()
Message-ID: <9B878634-A7C8-4FED-ABD1-E2AF72F7B289@gmail.com>

Hello list,

Questions about Layer.clone(): Is it supposed to work? I'm having  
major problems with it. My use-case is, I have a set of pre-defined  
layers in an included .js file, but I want users to be able to add  
multiple maps to a page, two or more of which may use the same layer.  
So, I'm trying to Layer.clone() a copy of each layer each time it gets  
put into a map. Couple of problems I've encountered so far:

1. It looks like the clone method is supposed to take either a null  
argument (which will return a clone of "this" layer), or a layer to  
clone. But, for example, if I call wmslayer.clone(), I get back an  
object with class = "OpenLayers.Layer", rather than  
"OpenLayers.Layer.WMS". This doesn't seem correct.

2. If I do something like this: wmslayerA = wmslayer.clone(wmslayer);  
wmslayerB = wmslayer.clone(wmslayer); then wmslayerA and wmslayerB  
have the same id...this doesn't seem right, and it seems to confuse  
the layer switchers for the two different maps...or something else is  
confusing them, because they're definitely confused.

3. The clone method is overridden in OpenLayers.Layer.Image , and it  
behaves differently--specifically, for a WMS layer  
wmslayer.clone(wmslayer) seems to work better, but for an Image layer  
imagelayer.clone() seems to work better...but it still doesn't work  
right.

Shouldn't somelayer.clone() always be the same as  
somelayer.clone(somelayer)? or am I misunderstanding something?  Is  
this supposed to work? Is it deprecated, or is there a better way to  
do it?

Example of some of the above problems (especially #2) can be seen  
here: http://s89238293.onlinehome.us/w/index.php?title=Two_Maps . The  
site is using OpenLayers 2.6.

Thanks!

-Matt W.

Without doing any specific research, I will say that Layer.WMS clone
should work, and I'm surprised it doesn't, but ingenerla that lcone is
one of the less commonly used methods, and I'm not entirely surprised
that it's not working for you.

Patches, are of course, welcome: there are no known outstanding issues
with loning, but we don't use it often, so I wouldn't be surprised to
hear bugs.

Chris,

Thanks for the reply. I'm willing to try and provide a patch, but I  
should probably make certain I'm making it do the right thing. So far,  
my assumptions are that a cloned layer should be identical to the  
source layer except for the following:

1. Should have a different, unique "id" property
2. Should have the "map" property cleared (as Layer.clone does, but  
Layer.Image.clone does not)

Anything else? You guys are far more familiar with the nuts and bolts  
than I am, so I don't know what other properties might need to be made  
unique or initialized.

-Matt

Subject: [OpenLayers-Users] Can't remove point feature OL 2.6

Hi Eric,

Sorry for the encrypted message. 
My Englisch has a little lack of knowledge, but this message was
incomplete.
I hope this one is clear.

I'm develop a application with add, modify en remove functionality.
In OL 2.5 I use drag, modify and remove feature. That works OK!
In OL 2.6 I get an error when removing a second or next point.

First:
I add points (or a combination of points and lines) to the vector layer.
Second:
If I remove a point it works OK.
If I want to remove a second point, I get this error: 'this.multipleKey
has no properties' SelectFeature.js Line 191 (FF2 and IE7)
Something changed the mode. If you hover the second or other points the
cursor is changed to drag mode.
In FF2 after I add a new point, I still get the error but the point is
removed. In IE7 only the error is displayed. 
If I remove a Line or Polyline it works OK.

(based on the example/modify-feature.html. 
Remove functionality look at Add comments.)

Regards, Fred

Fred,

Would you mind being more specific on the issue you're having. I'm
having problem understanding what's bothering you.

Thanks,

Yes, managed to get it to work. I have some Java code that pulls a
geometry out of a database (SDE) and writes it to a local file system
file. Seems OL is fairly fussy about the structure of the GML file.
Anyway, here is the OL code:
 
var fbnd = new OpenLayers.Layer.GML("Farm boundary", "./farmfiles/" +
farmid + ".xml", {style: farm_style});
                    map.addLayer(fbnd);
 
And here is a sample GML (I experimented with GML structure using one
of the OL examples that writes out GML to a text box, then emulated
that):
 
<wfs:FeatureCollection xmlns:wfs="http://www.opengis.net/wfs">
  <gml:featureMember xmlns:gml="http://www.opengis.net/gml">

Message-ID: <D55C90FACE4A43438A46BAD5005287B0019571@NT6S16-MARYVM.ad.maryville.edu>

Hello,
I am trying to display data from mapserver using openlayers and am using the example files as a reference.  I'm using ms4w and the mapserver.html example file with Open-layers2.5.  When I view the file it displays pink tiles but none of the layers.  The error that is listed when I open the pink tiles reads:  loadMap(): Web application error. CGI variable "map" is not set.  I'm not quite sure what the problem is but any help is appreciated.  I'll paste the mapserver.html file below with the altered sections in red.  I have been able to get an image to display when I add the rest of the wms request to the section that has mapserver.exe listed (I used http://localhost/cgi-bin/mapserv.exe?map=/ms4w/apache/htdocs/maryville_web/maryville.map&SERVICE=WMS in place of http://localhost/cgi-bin/mapserv.exe)
If you have any suggestions I would appreciate your help.
Thanks,
Todd

This might be because you haven't set the CGI variable "Map".
Specifically, you need to add a 'map' key/value pair to the params hash
(third arg to layer.mapserver).

Subject: [OpenLayers-Users] CloudAmber drop shadow
Message-ID: <4815D88D.2040405@gmail.com>

Good morning,

Last week Bill Bronsema and I updated to the latest version and found 
that the drop shadow was no longer part of the out-of-the-box CloudAmber 
popup.  So we made a 24 bit PNG that was close to the old style and 
tweaked the positioning and sizing numbers to handle the drop shadows.

Attached is the adjusted FramedCloud.js and 24bit PNG.

We were poking the numbers with a stick to try and figure out what the 
numbers did, and although we got it to work, I'm not sure the values are 
as neat as they could be.

Note also that we added a PNG hack so that the images would work in 
versions of IE older than 7.  The hack starts at line 274 in Framed.js:

             var imageCreator =
                 (this.isAlphaImage) ? OpenLayers.Util.createAlphaImageDiv
                                     : OpenLayers.Util.createImage;

             block.image = imageCreator(imgId,
                 null, this.imageSize, this.imageSrc,
                 "absolute", null, null, null
             );

             // apply png24 hack
             block.image.className = 'png24';

             block.div.appendChild(block.image);
             this.groupDiv.appendChild(block.div);



Specific fix is on line 284:

block.image.className = 'png24';

All the best,
Fred

Subject: [OpenLayers-Users]  Odd behaviour with IFrames
Message-ID: <16941704.post@talk.nabble.com>


Situation: An IFRAME (Joomla wrapper component) containing a HTML page with a
OpenLayers 2.6 Map (WMS layers over Google base layers)

Problem: Odd behaviour when zooming in/out. At first, zooming works
correctly.
Then I change f.ex. from Google Street Map to Google Satellite.
After the first base map change, the zoomed region is wrongly centered (map
center shifts a lot to South-East) making zoom unusable.

Other strange thing, the problem seems to arise ONLY with the Satellite
map...

... I'm puzzled, any hints?

Thx, that did it, this is a very active & helpful forum, thank you very much.
Hope i'll get the hang of java soon, so i won't have to bother you as much
:)

Now, i'd like to get a certain style through the options part of the
OpenLayers.Layer.Vector.addfeatures, but i'm lost with the syntax. I think
its something like this, tried a couple of approaches, but i'm kind of
cluelesss....

var France = {strokeColor : "blue", fillColor : "blue"}; 
vectors.addFeatures(g,France);

again, any pointers are much appreciated

Hi,

There is an on-going issue with Google at the moment with the Satellite
maps going bad. I am not sure what is going on however I have noticed it
and read about it on the Google maps user group. I thought they may be
rebuild tiles or something it has been going on now for about 1 week. It
even happens when using the maps.google.com url's and switching to close
in zoomed satellite images. The zoom and pan's go strange and centre on
the upper left or lower left view extents and show the zoom out message
at the wrong times. It may be worth others adding comments in the Google
maps group pages.

Thanks Chris,
That worked but now I have a single image that is being repeated over and over again.  What do I need to do to have the image tiled rather than repeated in each tile that appears in openlayers.
Thanks again for the help.
Todd

Message-ID: <BLU120-W481A9C7743CD5E4853920CE9D90@phx.gbl>


Hi all!

I come back here because I always have the same problem.
So, I have a .ewc file which represent the France. This file is in Lambert II (French position, centered on France).
Currently, I display this map with WGS84 projection but naturally, my map is distorded because this projection is centered on the equator.
So, if I try to displaying my map with the Lambert II projection, I obtain the following figure:

http://www.forumsig.org/attachment.php?attachmentid=2286&stc=1&d=1208951661

As you can see, there is a malfunction=> the repetition of a part of each tile.

I tried to add projection and units options to my map but nothing change. I think that is a OL probleme because my map is correctly display with Mapserver and without OL.

Thanks for your futur help and once more, excuse me for my English.

Have a nice day

Clement

Message-ID: <5b629bbf0804291150m5f386acdqf39ce4d7a36b2ee6@mail.gmail.com>

Hi all,

I need a little help here. I'm developing a printing system, but I'm
getting some
problem with the extents.

I'm trying to print the map viewport, so I'm using the map.getExtent() and
map.getCurrentSize() values and passing it to the server, which calls the
mapserver and generates the image with the specified extent and size.

The problem is that the printed area is not exactly the same as showed at
the viewport. The output area is around 20% larger.

What I'm doing wrong? How can I precisely calculate the viewport extents?

The client code is something like this:

    var currentSize     = map.getCurrentSize();
    var viewportWidth   = currentSize.w;
    var viewportHeight  = currentSize.h;
    var extent          = map.getExtent();
    var sPrintExtent    = extent.toBBOX();

    var url = 'print.php?' +
              'size=custom' +
              '&width=' + viewportWidth +
              '&height=' + viewportHeight +
              '&extent=' + sPrintExtent;

    window.open(url);


To better understand what I'm talking about, take a look at this
screenshot of my viewport:
http://jproton.com.br/sandbox/viewport.JPG

And in the output image:

my best regards,

Pedro Simonetti.

I can't think of any reason why this shouldn't work.

Christopher,

Thanks for your feedback.

So, are you saying that the value of map.getExtent() is supposed to be the
precise extent of the visible area of the map on the screen, isn't?

Another thing, I'm using a non-default projection, and I'm wondering if this
can somehow be related to a misconfiguration of projections in my files.

In fact I'm a little bit confused about the values should I use for
projection and maxResolution. Here's the gdalinfo of my tiff file.

Subject: [OpenLayers-Users] Trouble getting mapserver WMS layer to load in OL
Message-ID: <9c2015090804291848j5d4f7eb1v77d2b26d86b6b080@mail.gmail.com>

Hi,

I'm a new user of Mapserver and am having a hard time with getting layers
from a new mapfile to load in OpenLayers.  I've tested that my local
mapserver install is responding correctly to WMS requests, and it seems to
work correctly.  Here is the request, with some linebreaks for clarity;

http://localhost/cgi-bin/mapserv?map=/var/www/520_webmap/mapfiles/520_ECP.map
&SERVICE=WMS
&version=%221.1.122
&REQUEST=GetMap
&LAYERS=Wetlands
&STYLES=
&BBOX=775843.302946,602429.871045,848438.746010,635418.446144
&WIDTH=600
&HEIGHT=400
&FORMAT=png
&SRS=epsg:2286

This returns an image that contains all of the layers which are active at
the scale of the BBOX area.  However, I cannot seem to find the right syntax
to get the layer to load into OpenLayers.  I have taken one of the test.html
files, the one for a single wms, and have tested that it works with my
openlayers.js install.  This is that file:
-----------------------
<html xmlns="http://www.w3.org/1999/xhtml">
  <head>
    <title>OpenLayers Basic Single WMS Example</title>
    <link rel="stylesheet" href="../theme/default/style.css" type="text/css"
/>
    <style type="text/css">
        #map {
            width: 512px;
            height: 512px;
            border: 1px solid black;
        }
    </style>
    <script src="
http://localhost:8080/geoserver/www/openlayers/OpenLayers.js"></script>
    <script type="text/javascript">
        var map, layer;
        function init(){
            map = new OpenLayers.Map( 'map' );
            layer = new OpenLayers.Layer.WMS( "OpenLayers WMS",
                    "http://labs.metacarta.com/wms/vmap0",
                    {layers: 'basic'} );
            map.addLayer(layer);
            map.zoomToMaxExtent();
        }
    </script>
  </head>
  <body onload="init()">
    <h1 id="title">Basic Single WMS Example</h1>

    <div id="tags"></div>

    <div id="shortdesc">Show a Simple Map</div>

    <div id="map"></div>

    <div id="docs">
        This example shows a very simple layout with minimal controls.  This
example uses a single WMS base layer.
    </div>
  </body>
</html>
------------------------------

No matter how I edit the file though, when I point to my localhost mapserver
instance, I just get an empty map frame, with no map controls, or anything
inside of it.  Right now the layer portion looks like this:

    <script type="text/javascript">
        var map, layer;
        function init(){
            map = new OpenLayers.Map('map',
                                        {    maxExtent: new
OpenLayers.Bounds(775843.302946,602429.871045,848438.746010,635418.446144),
                                            maxResolution: "auto",
                                            projection:"SRS_not_defined"
                                        } );
                        layer = new OpenLayers.Layer.WMS(    '520_WebMap',
                                        "http://localhost/cgi-bin/mapserv?",
                                        {    layers: 'Wetlands',
                                            map:
'map=/var/www/520_webmap/mapfiles/520_ECP.map',
                                            format: 'image/png',
                                            request: 'getmap',
                                            transparent: "false"
                                        });
                        map.addLayer(layer);
            map.zoomToMaxExtent();
    </script>

I'm hoping one of you has encountered a similar problem and can give me some
advice for how to resolve it.

Thanks,

Roger

Thanks for that. In order to have your contribution added to OpenLayers,
it is best that you create a ticket in Trac and add this as a feature
[1]. Create a patch against the current OL version (2.6) or even better:
trunk. You can attach the image to the ticket.

Solutions provided on the mailing list get easily forgotten, which would
be a pity.

It is true. It is a constant and ongoing pity. :-(

Thanks guys,

Bill is going to follow up on your suggestion.

I initially thought sending it to this list would allow some folks to 
comment on what we did before putting it forward as a "solution".  It 
works for our needs, but poking around with the numbers to get the image 
with a drop shadow to work left us feeling a bit uneasy.

We were not sure that we changed the numbers as optimally as possible, 
even though visually it works.

All the best,
Fred

This is unfortunately the very gap that keeps most of the good work that people
do in the community from getting re-absorbed into the project.

It is unusual that folks have the time or resources to develop
*general* solutions
to problems they encounter when using OL (or any other FOSS project, I would
venture to say). The goal is generally solving the task at hand rather
than forming
a universal solution that might be helpful to others.

And that, of course, is nobody's fault. The only way to overcome it is
to convince
our managers that a little extra effort to give things back to the
community is a
worthwhile proposition: no simple task, indeed.

Just taking the step you did to write to the mailing list with your
work is more than
most people do and a great help as it is. If you could spend the time
to get your
work into a ticket in trac with a straightforward patch, it would be
even better... but
as I've said above, even just the email to the list is a generous gesture.

Subject: [OpenLayers-Users] Trouble getting mapserver WMS layer to load
	in OL

Hi Roger,
 
you must declare the right projection for your map. Without any option the
projection OpenLayers will use is EPSG:4326 with -180,-90,180,90 as extent.
So the response of the WMS request is all right, if you get blank tiles. 
 
Try something like this:
 
    var options = {
        projection: "EPSG:2286",
        //perhaps also 
        //maxResolution: ....
        units: "m",
        maxZoomLevel  : 16,
        //if set you must add your controls manuel after the map declaration
        //controls      : [],
        numZoomLevels : 16,
        //this is a guess
        maxExtent: new OpenLayers.Bounds(500000, 500000, 1000000, 1000000)
    };
    map  = new OpenLayers.Map('map',  options);

With maxResolution I am not all clear. I always set it. For Google it is
156543.0339.

Betreff: [OpenLayers-Users] Trouble getting mapserver WMS layer to load in
OL


Hi,

I'm a new user of Mapserver and am having a hard time with getting layers
from a new mapfile to load in OpenLayers.  I've tested that my local
mapserver install is responding correctly to WMS requests, and it seems to
work correctly.  Here is the request, with some linebreaks for clarity;

http://localhost/cgi-bin/mapserv?map=/var/www/520_webmap/mapfiles/520_ECP.ma
p
&SERVICE=WMS
&version=%221.1.122
&REQUEST=GetMap
&LAYERS=Wetlands
&STYLES=
&BBOX=775843.302946,602429.871045,848438.746010,635418.446144
&WIDTH=600
&HEIGHT=400
&FORMAT=png
&SRS=epsg:2286

This returns an image that contains all of the layers which are active at
the scale of the BBOX area.  However, I cannot seem to find the right syntax
to get the layer to load into OpenLayers.  I have taken one of the test.html
files, the one for a single wms, and have tested that it works with my
openlayers.js install.  This is that file:
-----------------------
<html xmlns="http://www.w3.org/1999/xhtml">
  <head>
    <title>OpenLayers Basic Single WMS Example</title>
    <link rel="stylesheet" href="../theme/default/style.css" type="text/css"
/>
    <style type="text/css">
        #map {
            width: 512px;
            height: 512px;
            border: 1px solid black;
        }
    </style>
    <script
src="http://localhost:8080/geoserver/www/openlayers/OpenLayers.js"></script>
    <script type="text/javascript">
        var map, layer;
        function init(){
            map = new OpenLayers.Map( 'map' );
            layer = new OpenLayers.Layer.WMS( "OpenLayers WMS",
                    "http://labs.metacarta.com/wms/vmap0",
                    {layers: 'basic'} );
            map.addLayer(layer);
            map.zoomToMaxExtent();
        }
    </script>
  </head>
  <body onload="init()">
    <h1 id="title">Basic Single WMS Example</h1>

    <div id="tags"></div>

    <div id="shortdesc">Show a Simple Map</div>

    <div id="map"></div>

    <div id="docs">
        This example shows a very simple layout with minimal controls.  This
example uses a single WMS base layer.
    </div>
  </body>
</html>
------------------------------

No matter how I edit the file though, when I point to my localhost mapserver
instance, I just get an empty map frame, with no map controls, or anything
inside of it.  Right now the layer portion looks like this:

    <script type="text/javascript">
        var map, layer;
        function init(){
            map = new OpenLayers.Map('map', 
                                        {    maxExtent: new
OpenLayers.Bounds(775843.302946,602429.871045,848438.746010,635418.446144), 
                                            maxResolution: "auto",
                                            projection:"SRS_not_defined" 
                                        } );
                        layer = new OpenLayers.Layer.WMS(    '520_WebMap', 
                                        "http://localhost/cgi-bin/mapserv?",
                                        {    layers: 'Wetlands', 
                                            map:
'map=/var/www/520_webmap/mapfiles/520_ECP.map',
                                            format: 'image/png',
                                            request: 'getmap',
                                            transparent: "false"
                                        });
                        map.addLayer(layer);
            map.zoomToMaxExtent();
    </script>

I'm hoping one of you has encountered a similar problem and can give me some
advice for how to resolve it.

Thanks,

Roger

Erik,

It was always our intention to submit this back to the community in the 
way you have described.

I just wanted to get some feedback on our approach before standing it up 
as a "solution".  It seems that the code was set up to be configurable, 
kind of like a style sheet, but in Javascript.  We adjusted the 
positioning and sizing values, following what patterns we could recognise.

Once we've filed the ticket, I'm sure we'll get that feedback so we can 
tidy it up if need be.

Thanks for the help with this.  It appears that the problem I was having was
due to the lack of having a declared projection in my OpenLayers.Map.  The
following, along with a declared projection in the MAP portion of my
mapfile, and a "wms_srs" parameter set in the WEB section of the mapfile
seems to work well.

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

                  {    maxExtent: new
OpenLayers.Bounds(716805.363551,570361.299368,832620.878780,660361.288174),
                    units: 'feet',
                    projection: "epsg:2286",
                    maxResolution: 'auto',
                    numZoomLevels: 16,
                    controls: []
                  });
var wetlands = new OpenLayers.Layer.MapServer('wetland_test', '
http://localhost/cgi-bin/mapserv?',
                  {    map: '/var/www/520_webmap/mapfiles/520_ECP.map',
                       layers: 'Wetlands',
                       format: 'image/png',
                  },
                  {buffer: 0, gutter: 15})

Erik,

Yeah that will be great! This is a cool feature,
I will love seeing it in a future release!

Subject: [OpenLayers-Users] OpenLayers + dBox + Postgres text search
Message-ID: <ae9185aa0804301957r5f189e28g19362a1e05e4b0a3@mail.gmail.com>

Apologies for the cross post to people with crowded mail boxes.

I've been working on an OpenLayers site that incorporates the dBox
tree legend that is popular with many MapServer users. dBox is based
on YUI and was developed by Steve Lime and others at the Minnesota
DNR. The site is still pretty sloppy but may be of interest:

   http://www2.tetonwyo.org/mapserver/ol.html

Also of possible interest is the use of the new PostgreSQL 8.3 full text search.

Rich
