Thank you for your answer.

I tried it, but it always show the default style. My code is like this.

theSLD_BODY= '<?xml version="1.0"
encoding="ISO-8859-1"?><StyledLayerDescriptor version="1.0.0"
xsi:schemaLocation="http://www.opengis.net/sld StyledLayerDescriptor.xsd"
xmlns="http://www.opengis.net/sld" xmlns:ogc="http://www.opengis.net/ogc"
xmlns:xlink="http://www.w3.org/1999/xlink"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><NamedLayer><Name>Linien</Name><UserStyle><Title>Linienobjekte
im WebGIS der
ETH</Title><FeatureTypeStyle><Rule><Name>Trockenmauer</Name><ogc:Filter><ogc:PropertyIsEqualTo><ogc:PropertyName>PflE_art_n</ogc:PropertyName><ogc:Literal>1780</ogc:Literal></ogc:PropertyIsEqualTo></ogc:Filter><LineSymbolizer><Stroke><CssParameter
name="stroke">#38A800</CssParameter><CssParameter
name="stroke-width">3</CssParameter></Stroke></LineSymbolizer></Rule></FeatureTypeStyle></UserStyle></NamedLayer></StyledLayerDescriptor>';


linien = new OpenLayers.Layer.WMS("Linien",url,params,options);

linien.mergeNewParams({"SLD_BODY":theSLD_BODY});

I tried also

linien.mergeNewParams({ SLD_BODY : theSLD_BODY });

After this the Layer is draw again. But it has still the same style.
Do you know what the problem could be?

It works with a cql filter!! *jupy*
Thank you everybody for different the solution strategies! Your awsome.

If somebody need an example:

var filter = "PflE_art_n=1780";

filterParams["cql_filter"] = filter;

linien.mergeNewParams(filterParams);

-->PflE_art_n is a Attribut name and linien is a wms layer.

Hi list,
I've a gml layer [1], It's possible read the attributes of this file
and, "onClick" event, open a pop-up?
Something like "fullRequestString" and wfs.
I'm trying different solutions unsuccessfully!!!

thanks

hello

I am new for Openlayer and GeoServer.I was created KML file from ArcGIS by

FYI: I've handled to produce a version which doesn't require
removal and re-addition of a layer:

Not sure about unwanted side-effects, but seems to work.

Hi Sarah,

Have you been able to make the selection work with a layer over the region
of selection?
I need to get that working desperately.
My code is not that Good.
It works in one machine but doesn't work in other.

Can you give me better code?
WFS.FromWMSLayer does not work in my case, I 'm using Mapserver.
The guy called Bart told me that he has code to make circle work instead of
box but didn't give the code since then.

Pl tell me how you got the selection layer working.

Thanks for your reply.

Okay, the basic code for circle selection in the GetFeature control is here:

http://trac.openlayers.org/ticket/2609

Please give it a try.

Best regards,
Bart

Hi,
to complete this. I've solved the problem with this lines of code :

                 newLayer.events.register("loadend", newLayer, 
function(evt){this.setVisibility(true);});
                 newLayer.visibility = false;
                 userContext.controller.map.addLayer(newLayer);
What happens:
If the layer is visible before loadend the symbols/graphics only show if 
they are in the buffer, now when layer is invisible while waiting for 
kml-data they come at the first time.

Hello List

I'm creating a feature with the features-edit tool and then committing 
this feature to some server in geojson format.

It looks as follows:
OpenLayers.Request.POST({
            url: Pronto.consts.Mapservice.URL.Base,
            callback: this.featureHandler,
            scope: this,
            headers: {
                "Content-Type": "text/plain"
            },

            params : {
                geojson : serializedJson,
                featureid : featureId,
                featuretype : Pronto.consts.layer.id.Annotation,
                action : "create"
                }
        });

and the handler:
featureHandler : function(request) {
        console.log(request);
    }


Everything on the firebug looks ok. but in web developer toolbar I get 
the error:
Error: no element found

Subject: [OpenLayers-Users] Show huge vector layers
Message-ID: <20100503092016.308570@gmx.net>

Hello,

I use OpenLayers to show the track of a user. The user uploads a gpx file and OpenLayers creates a vector and than shows the track. That's all working fine. But users can also upload track files with more than 10000 track points and that will slow down the zooming and scrolling of the map.


I thought about using only every n-th track point, but if I zoom in, the resolution of the track becomes more and more bad, so I had to recalculate the track points for every zoom level, which also slows down the browser.
So is there a way to limit the number of shown track points of a vector? 

Or is there a better way to solve my issue?

Thanks for your help and best regards.
Ren?

why not just use a map server?

Hi,

only one baselayer can be visible at once, if you define your WMS layer 
as overlays you should be able to have more than one active

Did you ever find a solution for this?  I am looking for a way to set a "top"
layer so that if data from different layers overlap, the data on my "top"
layer gets selected.

Hi Ren?,

About a year ago, I tackled a similar problem [1]  by putting 
FeatureServer [2] in front of my WFS server, acting as a WPS (sort of). 
Nowadays there are a few applications that can do real WPS (OGC 
standard), like PyWPS, Zoo, deegree (IIRC). The nice thing with FS was 
that I only needed to proved the resolution as an extra WFS parameter to 
get it to work in OL.

The idea is simple:
- convert your GPX data into something that GeoServer (or MapServer, 
etc) can consume and then output as WFS
- have a WPS act as a proxy between OL and your WFS and
- configure the WPS to simplify the features it returns, based on your 
map resolution. The more you zoom in, the less you have it simplify and 
vice versa.

I hope that helps.

Regards,

Roald

Hi Arnd...
I have some questions about that...

First I have a geo app using Openlayers/Mapserver WMS with SDE layers....
My application has a treeview with all layers, and a radiobox for each
layer... When I click in a layer?s radiobox a window with a GRID containing
all layer?s data is opened...
In that GRID, When I select a line (layer?s data), the Map should :
 1-) Highlight it
 2-) Zoom in data selected

Can I develope that using SLD and SLD_BODY ? Do you have any tip to how do
that?

Thanks

Hi,

this is just a matter of css. No need to change any file, just use a DOM inspector to see what CSS class the output has (should be something like "olControlAttribution", create a selector with that class (e.g. ".olControlAttribution) and give it an appropriate positioning in your application css.

Regards,
Andreas.

Hi,
  Coulnt find a solution with the vector layers nd I dint continue trying as
the vector layers were giving me other problems as well.
I changed my two layers to WMS layers and then found a workaround by making
the featurecount as 2 and parsing the result


Thanks

Message-ID: <E1O8yyV-0000Jk-00@smtp08.web.de>

Hi Paul,
 
SLD_BODY is a request parameter of a wms. If you can get from your grid a
reference to your OpenLayers WMS layer, then you can use 
 
yourWMSlayer.mergeNewParams('SLD_BODY' : ....).
 
if your wms have only one layer (in the eample below POLYGONS) to request,
you can use something like this
 
<StyledLayerDescriptor version="1.0.0" xmlns="http://www.opengis.net/sld"
xmlns:gml="http://www.opengis.net/gml"
xmlns:ogc="http://www.opengis.net/ogc"
xmlns:xlink="http://www.w3.org/1999/xlink"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.opengis.net/sld
http://schemas.opengis.net/sld/1.0.0/StyledLayerDescriptor.xsd">
<NamedLayer>
<Name>COUNTRY</Name>
<UserStyle>
<FeatureTypeStyle>
<Rule>
<PolygonSymbolizer>
<Fill>
<CssParameter name="fill">#f0f0f0</CssParameter>
<CssParameter name="fill-opacity">1.00</CssParameter>
</Fill>
<Stroke>
<CssParameter name="stroke">#646464</CssParameter>
</Stroke>
</PolygonSymbolizer>
</Rule>
</FeatureTypeStyle>
</UserStyle>
</NamedLayer>
</StyledLayerDescriptor>
 
as SLD_BODY to highlight the the features of the layer. Attention! You have
to delete the line feeds for the request. 
 
Zooming to the extent of the wms layer is not so easy, perhaps inpossible.
You can request the WMS GetCapabilities and hope that there the correct
extent are described for the layer. Or if the layer is also requestable as
WFS you can perhaps on that way get the extent of the layer. But I'm not
sure.
 
If you are the holder of the WMS server, I would suggest, that you calculate
the extent on other ways and adds it as array to your application.
 
Arnd

Hi Arnd...
I have some questions about that...

First I have a geo app using Openlayers/Mapserver WMS with SDE layers....
My application has a treeview with all layers, and a radiobox for each
layer... When I click in a layer?s radiobox a window with a GRID containing
all layer?s data is opened...
In that GRID, When I select a line (layer?s data), the Map should :
 1-) Highlight it 
 2-) Zoom in data selected

Can I develope that using SLD and SLD_BODY ? Do you have any tip to how do
that?

Thanks

Thanks Arnd!

So, I have 3 WMS layers: Roads, GasStation, Country...
The user will select the Layer with radiobutton, and after select one data
in Grid...

So I?ll use selectedWMSLayer.mergeNewParams with a SLD_BODY ...

Is that right?

And how about Mapfile configuration, Am I suppossed to change anything?
What?

Thanks

Subject: [OpenLayers-Users] Basic marker questions
Message-ID: <x2yd9b01a1005031428y940f9fb6lfaa8336fa44bcb3@mail.gmail.com>

Hi everyone,

I'm working on an application that allows the user to add lines and vertices
to the map, to construct routes. In Google Maps, this would simply be
markers and polylines.

Using the OpenLayers abstraction layer, should I be using OpenLayers.Marker?
What about the line segments? If they're on a separate layer, will they
still be able to receive clicks?

I read elsewhere that the use of Marker and Layer.Markers is effectively
deprecated in the OpenLayers world, in favour of Layer.Vector. Is this true?
Is there one of the basic examples that demonstrates dynamically adding and
removing different objects from a Layer.Vector? Ideally, something like:
click the map to create a marker, click the marker to delete it.

Please note that I do not wish to use the standard editing toolbar that
comes with OpenLayers?my application is fairly specialized, so I will need
to build up this functionality from scratch.

Thanks!

Mike

Hi,

Just in case someone encounters the same problem (i. e. when moving the map,
it is printed in its initial position), I solved it by adding the position
of the viewport (map.layerContainerDiv.style.left and
map.layerContainerDiv.style.top), and then adding the left value of the
viewport to the $tile->x and the top value of the viewport to the $tile->y
in the calls to imagecopymerge_alpha.

Here is my full client code (I encapsulated the map object within an
object):

this.print = function(print_url, callback) {
		var size = this.map.getSize();
		var tiles = [];
		
		var nb_layers = this.map.layers.length;
		var layeri = 0;
		var nb_vector_layers = 0;
		var features = [];
		for (layeri = 0; layeri < nb_layers; layeri++) {
			// if the layer isn't visible at this range, or is turned off, skip it
			var layer = this.map.layers[layeri];
			if (!layer.getVisibility()) continue;
			if (!layer.calculateInRange()) continue;
			if (layer.grid) {
				// iterate through their grid's tiles, collecting each tile's extent and
pixel location at this moment
				var grid_length = layer.grid.length;
				var row_length = 0;
				var tilerow = 0;
				var tilei = 0;
				for (tilerow = 0; tilerow < grid_length; tilerow++) {
					row_length = layer.grid[tilerow].length;
					tilei = 0;
					for (tilei = 0; tilei < row_length; tilei++) {
						var tile     = layer.grid[tilerow][tilei];
						var url      = layer.getURL(tile.bounds);
						var position = tile.position;
						var opacity  = layer.opacity ? parseInt(100*layer.opacity) : 100;
						var bounds = tile.bounds;
						tiles[tiles.length] = {url:url, x:position.x, y:position.y,
opacity:opacity, bounds:{left:bounds.left, right: bounds.right, top:
bounds.top, bottom: bounds.bottom}};
					}
				}
			} else {
				// get the features of the layer
				var olFeatures = layer.features;
				var features_temp = [];
				var styles = {};
				var nb_features = layer.features.length;
				var featuresi = 0;
				var nextId = 1;
				for (var i = 0; i < nb_features; i++) {
					var feature = olFeatures[i];
					var style = feature.style || layer.style ||
layer.styleMap.createSymbolizer(feature, feature.renderIntent);
					if(feature.geometry) {
						if (feature.geometry.CLASS_NAME.search(/point$/i) >= 0) {
							var fpos = this.map.getLayerPxFromLonLat(new
OpenLayers.LonLat(feature.geometry.x, feature.geometry.y));
							if(fpos != null) {
								features_temp[featuresi] = {type: 'point', x: fpos.x, y:fpos.y,
style: style};
								featuresi++;
							}
						}
					}
				}
				features[nb_vector_layers] = features_temp;
				nb_vector_layers++;
			}
					
		}

		// hand off the list to our server-side script, which will do the heavy
lifting
		var tiles_json = JSON.stringify(tiles);
		var features_json = JSON.stringify(features);
		var viewport_left = parseInt(this.map.layerContainerDiv.style.left);
		var viewport_top = parseInt(this.map.layerContainerDiv.style.top);
		var viewport = {top: viewport_top, left: viewport_left};
		var viewport_json = JSON.stringify(viewport);
		var scale = Math.round(this.map.getScale());
		
		OpenLayers.Request.POST(
		  { url:print_url,
		
data:OpenLayers.Util.getParameterString({width:size.w,height:size.h,scale:scale,viewport:
viewport_json,tiles:tiles_json,features:features_json}),
			headers:{'Content-Type':'application/x-www-form-urlencoded'},
			callback: callback
		  }
		);

Subject: [OpenLayers-Users] Google / Yahoo Geometry transfrom??
Message-ID: <1272924735788-5000481.post@n2.nabble.com>


I've decided to try and use openlayers for a small project I'm working on ...
basically a little website that users can hover over block of land and get
information.

I'd like to give the user the option of having yahoo maps or even google
maps as the background.

I can get a map with yahoo maps background.

However I can't seem to transform my geometry ... at all (Example of a
single point)...
I thought it would transform my point into EPSG 4236 from EPSG 28356 ?

<script src="OpenLayers-2.8/lib/OpenLayers.js"
type="text/javascript"></script>
    <script src="lib/proj4js-combined.js" type="text/javascript"></script>
...

...
var map = new OpenLayers.Map('map', {projection: new
OpenLayers.Projection("EPSG:4326")});
        var layer = new OpenLayers.Layer.Yahoo("Yahoo");
        map.addLayer(layer);
        map.zoomToMaxExtent();
        map.addControl(new OpenLayers.Control.MousePosition());
        var proj = new OpenLayers.Projection("EPSG:28356");
        map.setCenter(new OpenLayers.LonLat(511500, 6966000).transform(proj,
map.getProjectionObject()), 10);

Subject: [OpenLayers-Users] Documentation of apparent functionality
	duplication?
Message-ID: <z2td9b01a1005031520tbf4054d8gdeb4801a450eb95b@mail.gmail.com>

Hi again,

I'm confused at a number of points where OpenLayers seems to contain
multiple possible ways of doing the same thing. For example, what is a
Geometry.Point? Is it closer in spirit to a LonLat or a Pixel? Why does its
constructor take x and y rather than a LonLat or Pixel?

Is there an FAQ or some kind of documentation somewhere that disambiguates
these things a little and explains which aspects are by-design, and which
are the result of heritage?

Thanks,

Mike

Subject: [OpenLayers-Users] Ho to add a marker with custom Icon and Text
Message-ID: <m2x94816dad1005031842ja9741c04v15bfb5540a4a5d45@mail.gmail.com>

hello All, i myself was recently working on the problem of adding a custom
marker with custom text, and with the help of open-layers examples code i
was able to achieve following:
1. Add a marker with a custom icon and label, each time i click  on the map.

2. Able to drag markers

I have only this suggestion that this functionality is pretty basic and
should be made part of editing toolbar, along with the option to save and
load KML data.

Here is the complete working code: You can copy paste this code in an html
file in the open-layers 2.9 examples folder and it should work fine :-)

Subject: [OpenLayers-Users] RootContainer styleMap problem- IE
Message-ID: <1272944676994-5001602.post@n2.nabble.com>


In IE 7/8 when I create a SelectFeature control and pass in an array of
layers, all of my features' styles  are lost (am using a custom StyleMap).  

If I modify Control/SelectFeature:initLayer to pass the styleMap to the
RootContainer constructor, the styles will take effect if I redraw after
activating the tool.  However IE makes such a redraw operation painfully
slow.

Is there any way in IE that I can activate the SelectFeature control with an
array of layers and have my features keep their styling without an expensive
redraw of the layers?  As usual, this problem doesn't exist in other
browsers.

Ideas are greatly appreciated.  Thanks!

I forgot to add that my Point features with an externalGraphic retain their
styling (no problems).  The loss of styling issue seems to only occur with
Polygons, Polylines, etc.

Thanks for the help Andreas,



I tried using setTimer , but this resulted in intermittent results (depending on the timing of each line draw I believe) and a flickering circle in all broswers.



A simplified version of the code I am using is as below (I have omitted the map with a toolbar).  I hope it isn't too convoluted!



When using IE and using a polyline tool to draw a line (a circle with a diameter of 10 will be drawn around the last point) a double click will not terminate the line (single then wait then double is needed).



Please note I am using an array stored in e.feature.geometry.attributes to store the rangeCircle within the Vector (as passed to the handler in e.feature).



waypointLayer.events.on({'sketchstarted': sketchStarted});

waypointLayer.events.on({'sketchmodified': sketchModified});



function sketchStarted(e)

{

      e.feature.geometry.attributes = new Array();

      e.feature.geometry.attributes['circle'] = createCircle(e.feature.geometry.getVertices());

}



function sketchModified(e)

{

      e.feature.geometry.attributes['circle'].destroy();

      e.feature.geometry.attributes['circle'] = createCircle(e.feature.geometry.getVertices());

      waypointLayer.addFeatures(e.feature.geometry.attributes['circle']);

}



function createCircle(vert)

{

      return new OpenLayers.Feature.Vector(

            OpenLayers.Geometry.Polygon.createRegularPolygon(vert[vert.length-1], 10, 50)

      );

}



Any help would be really appreciated!

I think the "if" part in the above sentence screws your application.

This sounds like an application issue. You could try to draw the other

element in the sketchmodified handler using setTimeout. If that does

not work, try to create a minimal example that shows the issues, so it

will be easier for others to help.

There is no destroy method on an Object, unless you have something that overrides Object.

Subject: [OpenLayers-Users] measure layer
Message-ID: <312413.46063.qm@web27403.mail.ukl.yahoo.com>

Hi all,
using measure control, after I have drawn a line (or polygon) I get the relative value for length (or area), and then,  if I make a new measure drawing a new line, the previous one disappear.
I would like to have instead a "mesure layer" that allow to make multiple measures, drawing multiple lines each one with a progressive number as label.
What is the best way to get this result?
Is it possible to make this layer a real layer (turning it on/of)?

Thanks
Marco

I think you need to create your own vector layer, and then listen to the
measure event. In the event handler you can create a feature using the
geometry returned and add it to your layer.

Bart

Hi,

posting an example that shows the issue would help. I suspect that your StyleMap has incomplete symbolizers.

Andreas.

Message-ID: <4BDFFD6F.7050802@iki.fi>

TelaScience's Landsat7 tile server has been down for a while now, and 
this time even the main page of openlayers.org and the code examples 
seem to be affected.  Have they just changed their server names again, 
or is it gone for good?  Any alternatives?  I'm using the same servers 
as the main apage:

var jpl_wms = new OpenLayers.Layer.WMS("Imagery",
                 ["http://t1.hypercube.telascience.org/tiles?",
                  "http://t2.hypercube.telascience.org/tiles?",
                  "http://t3.hypercube.telascience.org/tiles?",
                  "http://t4.hypercube.telascience.org/tiles?"],
                 {layers: 'landsat7'}
             );

Once again, I think there would be a market for hosting a reliable paid tile server out there somewhere...

Message-ID: <224DBDAF88A6AC47BD22432815351BE007EC87EF@nekaposta1>

 
Hello,

I'm trying to make a tool like yours, indeed I asked this before but
nobody seemed to know the solution, but I'm not able to figure out how
to process the features data in php script. Can you please give me some
clues to solve the problem??

Another question I've got is that I see that you're just parsing Point
fetures. If I would want to parse polygons or lines how could I do it?
Do I have to use GeoJSON Syntax??

Thanks.

P.S. I'm a bit newbie, I know.

Hi,

Just in case someone encounters the same problem (i. e. when moving the
map, it is printed in its initial position), I solved it by adding the
position of the viewport (map.layerContainerDiv.style.left and
map.layerContainerDiv.style.top), and then adding the left value of the
viewport to the $tile->x and the top value of the viewport to the
$tile->y in the calls to imagecopymerge_alpha.

Here is my full client code (I encapsulated the map object within an
object):

this.print = function(print_url, callback) {
		var size = this.map.getSize();
		var tiles = [];
		
		var nb_layers = this.map.layers.length;
		var layeri = 0;
		var nb_vector_layers = 0;
		var features = [];
		for (layeri = 0; layeri < nb_layers; layeri++) {
			// if the layer isn't visible at this range, or
is turned off, skip it
			var layer = this.map.layers[layeri];
			if (!layer.getVisibility()) continue;
			if (!layer.calculateInRange()) continue;
			if (layer.grid) {
				// iterate through their grid's tiles,
collecting each tile's extent and pixel location at this moment
				var grid_length = layer.grid.length;
				var row_length = 0;
				var tilerow = 0;
				var tilei = 0;
				for (tilerow = 0; tilerow < grid_length;
tilerow++) {
					row_length =
layer.grid[tilerow].length;
					tilei = 0;
					for (tilei = 0; tilei <
row_length; tilei++) {
						var tile     =
layer.grid[tilerow][tilei];
						var url      =
layer.getURL(tile.bounds);
						var position =
tile.position;
						var opacity  =
layer.opacity ? parseInt(100*layer.opacity) : 100;
						var bounds =
tile.bounds;
						tiles[tiles.length] =
{url:url, x:position.x, y:position.y, opacity:opacity,
bounds:{left:bounds.left, right: bounds.right, top:
bounds.top, bottom: bounds.bottom}};
					}
				}
			} else {
				// get the features of the layer
				var olFeatures = layer.features;
				var features_temp = [];
				var styles = {};
				var nb_features = layer.features.length;
				var featuresi = 0;
				var nextId = 1;
				for (var i = 0; i < nb_features; i++) {
					var feature = olFeatures[i];
					var style = feature.style ||
layer.style || layer.styleMap.createSymbolizer(feature,
feature.renderIntent);
					if(feature.geometry) {
						if
(feature.geometry.CLASS_NAME.search(/point$/i) >= 0) {
							var fpos =
this.map.getLayerPxFromLonLat(new OpenLayers.LonLat(feature.geometry.x,
feature.geometry.y));
							if(fpos != null)
{
	
features_temp[featuresi] = {type: 'point', x: fpos.x, y:fpos.y,
style: style};
	
featuresi++;
							}
						}
					}
				}
				features[nb_vector_layers] =
features_temp;
				nb_vector_layers++;
			}
					
		}

		// hand off the list to our server-side script, which
will do the heavy lifting
		var tiles_json = JSON.stringify(tiles);
		var features_json = JSON.stringify(features);
		var viewport_left =
parseInt(this.map.layerContainerDiv.style.left);
		var viewport_top =
parseInt(this.map.layerContainerDiv.style.top);
		var viewport = {top: viewport_top, left: viewport_left};
		var viewport_json = JSON.stringify(viewport);
		var scale = Math.round(this.map.getScale());
		
		OpenLayers.Request.POST(
		  { url:print_url,
		
data:OpenLayers.Util.getParameterString({width:size.w,height:size.h,scal

If you really need to have 2 layers, one for the lines and one for the 
intersections (points), my guess is that you should draw the lines only 
and once one is finished drawing, get all its vertices and add them to 
your other layer.  You should be able to accomplish this by registering 
a "featureadded" event on your DrawFeature control used to draw your lines.

Hey, thanks for your response. One more question (for the moment).


> I read elsewhere that the use of Marker and Layer.Markers is effectively
>> deprecated in the OpenLayers world, in favour of Layer.Vector. Is this true?
>>
> Yes, highly recommended.


My markers are effectively just little square and round tokens. Should I
render them using the SVG abilities of Layer.Vector, or should I use a
graphics program to make them as PNG icons? I need to be able to rotate
them?does that affect anything?

Also, it seems like the coordinates of Layer.Vector are with respect to
latitude and longitude rather than the viewport?how would I make my markers
size the same independent of zoom level?

Finally, in my initial tests, it seems that the vector shapes experience a
lot of "drift" as I drag the map around. My application requires that they
be pretty precisely fixed?is there a way to crank up the precision on this?

Thanks again.

Hi David,

Here is the code I'm using on the server side to parse the features:

$red = imagecolorallocate($image, 255, 0, 0);
		$black = imagecolorallocate($image, 0, 0, 0);
		
		foreach($features as $feature_array) {
			if(count($feature_array) > 0) {
				foreach($feature_array as $feature) {
					if($feature->type == "point") {
						if($feature->style) {
							$dst_x = $feature->x + $viewport->left;
							$dst_y = $feature->y + $viewport->top;
							if($feature->style->externalGraphic) {
								// Draw the external graphic
								$tempfilename = basename($feature->style->externalGraphic);
								$tempfile =  sprintf("%s".DS."%s", $graphs_directory,
$tempfilename);
								if(!file_exists($tempfile)) {
									$tempfiles[] = $tempfile;
								
file_put_contents($tempfile,file_get_contents($this->relative_to_absolute_url($feature->style->externalGraphic)));
								}
								list($fwidth, $fheight, $fformat) = @getimagesize($tempfile);
								$feature_image = $this->image_create_from_format($fformat,
$tempfile);
								$dst_x = $dst_x - ($fwidth / 2);
								$dst_y = $dst_y - ($fheight / 2);
								imagecopy($image, $feature_image, $dst_x, $dst_y, 0, 0, $fwidth,
$fheight);
							} else {
								// something needs to be drawn
								$color_rgb = $this->html2rgb($feature->style->fillColor);
								$color = imagecolorallocatealpha($image, $color_rgb[0],
$color_rgb[1], $color_rgb[2], 40);
								$radius = $feature->style->pointRadius * 2;
								imagefilledellipse($image, $dst_x, $dst_y, $radius, $radius,
$color);
							}
							if($feature->style->label != "") {
								imagestring($image, 2, $dst_x, $dst_y, $feature->style->label,
$black);
							}
						}
					}
				}
			}
		}

As you said, I'm only parsing points because, in my case, I'm only
interested in points (I don't have any layer in my map that describes
polygons). However, I'm pretty sure it must be possible to do the same thing
for polygons using the imagepolygon GD function
(http://www.php.net/manual/en/function.imagepolygon.php)...

Also, if you are interested and maybe if other people are interested in this
functionality too, it could be interesting to create an open source library
in PHP to implement this functionality. Let me know if you are in, and if
other people are interested, please let me know...

Subject: [OpenLayers-Users] Please help me configured popup GetFeatureInfo
Message-ID: <1272984618672-5003719.post@n2.nabble.com>


Hello

I am a starter of OL and GeoServer. I have tried to modify popup codes where
I get from http://openlayers.org/dev/examples/getfeatureinfo-popup.html.  My
map work very well but the popup seems  a trouble.
I have two questions for asking.
1. When I click other than a point the popup show up with a blank. I don?t
like it so I write my code like this
var info = new OpenLayers.Control.WMSGetFeatureInfo({
            url: 'http://localhost:8080/geoserver/wms', 
            title: 'Identify features by clicking',            						
			layers: [herb],
			vendorParams: {"FEATURE_COUNT": "100"},            
			//maxfeatures: 200,
			vendorParams: { format : 'image/png' }, 
			//handlerOptions: {'hover':{delay:500}},			 
			eventListeners: {
		    getfeatureinfo: function(event) {
        
				if (popup != null) {
            		popup.destroy();
		            popup = null;
        		}
				if((event.text).length != 1){
				        map.addPopup(popup = new OpenLayers.Popup.FramedCloud(
                        "chicken", 												                        						                        						
						map.getLonLatFromPixel(event.xy),						
                        null,
                        event.text,
                        null,
                        true
                    ));					        		        	
				} }
            }
        });
        map.addControl(info);
        info.activate();	
It still doesn?t work. I get idea from an old thread.

http://img260.imageshack.us/img260/4239/34618760.jpg 



2. When I look in my map at high level, the points seem to overlap each
other. After I click on the point, the popup query all the point. I want the
top most only query. I am using WMS layer not Vector layer. Is it impossible
for WMS layer? Can anyone tell me ideas to write a code? If you don?t mind
please give me some example or explain.
Sorry for my English

Subject: [OpenLayers-Users] Occasionally getting hundreds of requests in a
	short time
Message-ID: <4BE06580.6050502@nsidc.org>

I'm working on an application using OpenLayers that has a Tilecache/WMS
backend to serve the map images.  For the most part, it runs pretty
smoothly without too much load on the mapserver.  However, every once in
awhile, maybe once a week or so, something happens where several hundred
requests are sent to the backend in a very short amount of time, causing
the server to crash or grind to a halt because of it.

While I'm sure this is due, in part, to some action by a user, I'm not
quite sure what it could be.  Even though I'm using Tilecache, the
requests that are eventually causing this are going to the WMS server
itself, indicating that the cache does not currently have the requested
images.

I'm not sure if this is a "problem" with OpenLayers itself, but it is
becoming a problem for our server.  Has anyone experienced this in their
applications?  If so, what may be the cause?  About the only thing I can
think of is maybe a user using the scroll wheel to rapidly zoom in (and
out?) of an area that hasn't been cached, or perhaps many users trying
to hit the cache at nearly the same time (which could be from some kind
of lab or class or something).

Thanks in advance,

It's already the case, see in the same example above (try zooming, 
you'll see that the markers remain the same size).

This shouldn't be the case, could it be related to this (wild guess):

Okay, yes, I have now got this working, but it's been extremely painful. I
can share my code for others if it would be helpful to do so, but I feel
certain that there must be a better way. It feels extremely hacky to be
constantly loading lat/lon pairs into Point objects, just to "transform"
them to the map coordinates. (Which, of course, the map methods still refer
to and interact with as LonLat objects, even the contents are clearly not
latitudes and longitudes, but another coordinate system altogether.)

Seems like if I pass it LonLat objects, it just know to do the right thing,
as Google does.

Hey folks,

I'm using OpenLayers 2.9 and everything works fine except when it comes to
IE 8.  I've coded a click event to display the results from a getfeatureinfo
wms request.  The error I receive is 'this.size.w' is null or not an object,
and it refers to the OpenLayers.js build.  I've tested this with several
different builds including the OpenLayers full build and it still breaks. 
However, everything works great within Mozilla, Safari and Opera.  I'm not
sure what the deal is.  Here is the line the error occurs on:

if((origTL.x+this.size.w)>(mapSize.w-this.map.paddingForPopups.right)){newTL.x=mapSize.w-this.map.paddingForPopups.right-this.size.w;}

Anyone else experience this issue?  If so, how did you resolve it? 
Unfortunately, our shop is mainly using IE.  Any suggestions would be great
appreciated.

Thanks.

Hi,

this sounds like a known regression. It should be fixed in trunk and OpenLayers 2.9.1.

See http://trac.openlayers.org/ticket/2414.

Andreas.

It turns out my problem occurs because I am setting a custom layer.id after I
create an OpenLayers.Layer.

I guess my next question is:  Is there any way to provide your own custom ID
when creating a layer?  If you provide it via the options object, the div
never gets created.

I would love to see an example of how you got this working in code.  

 

I  am having problems with hand parsing a kml file to pull out the zoom box
points and use them for bounds, pull out the marker point and use that for
the lonlat, and then letting the automatic kml loader load the linestrings
in the kml file that show all the points hooked together of where my vehicle
has been.  I can get it working without the spherical mercator (and the
markers not in the right place on the commercial layers), but once I follow
the directions for mercator using the forwardMercator calls: 

 

marker = new
OpenLayers.Marker(OpenLayers.Layer.SphericalMercator.forwardMercator(lon,
lat));

 

I get neither markers nor linestrings.

 

I am unable to request help here for this issue as I cannot get the
non-mercator version to run on my current server space, only on my
development laptop.

"Okay, yes, I have now got this working, but it's been extremely painful. I
can share my code for others if it would be helpful to do so, but I feel
certain that there must be a better way. It feels extremely hacky to be
constantly loading lat/lon pairs into Point objects, just to "transform"
them to the map coordinates. (Which, of course, the map methods still refer
to and interact with as LonLat objects, even the contents are clearly not
latitudes and longitudes, but another coordinate system altogether.)

 

Seems like if I pass it LonLat objects, it just know to do the right thing,
as Google does."

Does anyone have a PHP ProxyHost example?  (My web hosting is windows, not
linux, so it does not support cgi.)

Also, in the instructions (wiki FAQs) it says:
 
	Once a proxy host script has been installed, you must then edit the
OpenLayers.ProxyHost variable to match that URL. 

	Given the standard Apache configuration: 

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


Where would I find the OpenLayers.ProxyHost variable to point it to my
phpProxy location?

I am hoping this might be the solution to file not found issues on my server
(but not on my development laptop.)

The only workaround would be to do something like

var layer = new OpenLayers.Layer(...);
document.getElementById(layer.id).id = myCustomId;
layer.id = myCustomId;

The above should work, but is untested.

Hi,

looks indeed like a misuse of our wiki.

Chris, can you please remove user BrendonMiller from trac? I have reverted the change that added these links.

Thanks,
Andreas.

Subject: [OpenLayers-Users] Panoramio photos as a vector layer
Message-ID: <AANLkTilU8jMjr4QZhUuKm1rP2PIPyoLkYtC9KlBE2iRl@mail.gmail.com>

Hi list,

This is my first post.

I have developed an html-javascript script to load Panoramio's  photos in
OpenLayers. Panoramio  (http:/www.panoramio.com) is a great store of
georeferenced photos accesible with a public API (
http://www.panoramio.com/api/) that allows to get a doc in JSON format.
A how-to explanation can be viewed as a post in our blog (in spanish -
http://www.gisandchips.org)
:http://www.gisandchips.org/2010/05/04/openlayers-y-panoramio/

We have also made two examples:

1. OpenLayers with OpenStreetMap base layer and Panoramio:
http://www.gisandchips.org/demos/j3m/panoramio/panoramio.html
2. OpenLayers with WMS base layer and Panoramio:
http://www.gisandchips.org/demos/j3m/panoramio/panoramio_4326.html

Now, my questions:
1. How can I design a new custom layer format (
http://docs.openlayers.org/library/formats.html) for Panoramio to load the
layer as usual (example: panoLayer = new
OpenLayers.Layer.Format.Panoramio(<json data>).
 I make an unique JSON data request, but I don't know how to make  the layer
persistent (new httpRequest)  for every zoom-pan event which  loads new
data.

Any suggestions are welcome

Regards

Hi Marjie,

This is what I have so far: http://sandbox.mikepurvis.com/maps/clearpath/

(doubleclick to create more waypoints)

Like I say, it's a real hack, especially this kind of stuff:

        var lonlatProjected = map.getLonLatFromViewPortPx(e.xy);

        /*alert("You clicked near " + lonlatProjected.lat + " N, " +
> lonlatProjected.lon + " E");*/



        var point = new OpenLayers.Geometry.Point(lonlatProjected.lon,
> lonlatProjected.lat);

        var pointFeature = new OpenLayers.Feature.Vector(point, null,
> style_waypoint);

        vectorLayer.addFeatures([pointFeature]);


If you re-enable the alert, you see that it's very clearly _not_ a true
latitude and longitude coming out of the getLonLatFromViewPortPx?it's a
coordinate pair in some other scheme that's been packaged into a LonLat.

Perhaps one of the gurus could help break this down a bit for me. Is this an
expected behaviour, or did I do something wrong in the setup phase? My
understanding so far is that Pixel is for x/y pairs representing screen
coordinates, LonLat is for x/y pairs representing global coordinates, and
Point is for unitless x/y pairs representing anything that needs to be
transformed or otherwise manipulated. Is that reasonable, or am I still out
to lunch on it?

Thanks,

Mike

Subject: [OpenLayers-Users] Multiple click control stopClick precedence/order
Message-ID: <z2k3d59894a1005051012kfbf9875bn2cdeb6862c20862a@mail.gmail.com>

Hello list,

I'm trying to set up a vector layer to respond to click events, and also
have a map-level click handler that gets fired if the click was not on one
of my features. I'm doing this with two controls, one with a
OpenLayers.Handler.Feature and one with a OpenLayers.Handler.Click.

This is what puzzles me:

In my first attempt: The feature click control is added first, and its
stopSingle value is true. The map click control is added last, and its
stopSingle value is false. When I click on a feature, the handler for the
feature click control fires first (this makes sense), and then the map click
control fires (this didn't make sense to me).

Then, I tried setting stopSingle = true on the map click control as well.
This stopped the feature click control from firing at all! So, I conclude
that--even though the map click control was added last, AND executes last,
the stopSingle value on the map click handler is evaluated first?? Why is
this? How can I ensure that the feature click handler control is able to
stop the propagation to the map click handler, preferably regardless of the
order in which they are added to the map?

To eliminate some confusion: yes, I know about the SelectFeature control. So
far as I can tell, I can't use that--my features are points with large,
mostly transparent icons that tend to overlap and cover the whole map (in
which case SelectFeature intercepts mousedowns on the whole icon and makes
drag-panning impossible), therefore I only want to respond to clicks near
the center (canceling propagation in that case). If someone can tell me how
to make that work with SelectFeature, I'd be glad to use that instead.

Help? Thanks!

-Matt

For reference, here is essentially my code (though the feature click control
gets added in a completely different place, it happens in this order in my
example):

        var vectorLayer = new OpenLayers.Layer.Vector(...);
        /* ...set up vector layer with features, etc... */
        OpenLayers.Control.ClickFeature =
OpenLayers.Class(OpenLayers.Control, {
            defaultHandlerOptions: {
                'single': true,

I'm trying to build a smaller openlayers.js, following the instructions 
in the build folder.

I've looked everywhere for a list of components that I could just add 
the [include] section of my .CFG file for the build script and then 
trial and error just start deleting...

Of course, I started out by creating a .CFG file that just listed the 
components I thought I needed by inspecting my html file and looking for 
components I was using.

So,  What's the easiest/foolproof way of creating a .CFG file that has 
just the modules I need for my app?

Thanks,
Percy

Hello,

I have problem to use this kml file with openlayers:
http://www.dav-felsinfo.de/export/cliffs_kml.php?1=22

E.g. I use this example 
http://www.openlayers.org/dev/examples/sundials.html and change only a
little bit:

            var sundials = new OpenLayers.Layer.Vector("KML", {
                projection: map.displayProjection,
                strategies: [new OpenLayers.Strategy.Fixed()],
                protocol: new OpenLayers.Protocol.HTTP({
                    url: "http://www.dav-felsinfo.de/export/cliffs_kml.php?1=22",
                    format: new OpenLayers.Format.KML({
                        extractStyles: true,
                        extractAttributes: true
                    })
                })


Then I see only one icon in the sea nearby Africa and not in Germany. :-(

But the result should looks like that:
http://maps.google.de/maps?f=q&hl=de&q=http://www.dav-felsinfo.de/export/cliffs_kml.php?1=22

I try some other kml files and it works.
Could it be that this kml file is incorrect?
Any ideas?

thanks,
Dirk

Hi,

It seems to be a projection error. Your data come in EPSG:4326 (-180 - 180,
-90 - 90), that's in sphericalMercator equal 0,0 near Africa.

I would think, that you use map.projection sphericalMercator and for
map.displayProjection also sphericalMercator. 

Set in the layer declaration projection: "EPSG:4326" and your data should be
at the right place.

Nevermind, just search for all of the New statements in your file, and 
put a line in the .cfg for each unique one.

much more deterministic:-)

Thanks for the help on IRC!

Subject: [OpenLayers-Users] POI lost when dragging the map

Hi guys

I am displaying POIs (speed cameras) via WMS as overlay on top of a Google base map. When I drag the map (in my case) to the left the POI markers disappear from the map. When I drag the map back they reappear. It appears data is coming back from GeoServer each time, but doesn't always make it on the map...

I am using 
* OpenLayers 2.8
* GeoServer 2.0.1
* Firefox 3.6.3

Data is coming from Oracle, but the same happens if I attach an shapefile data store. Native SRS of the layer is EPSG:2193 (EPSG:NZGD2000 / New Zealand Transverse Mercator ), but it doesn't seem to make a difference whether I let GeoServer serve them with EPSG:2193 (native) or reproject to EPSG:900913.

I also just realised that the phenomenon happens with all my WMS layers. I suspect I am missing something very obvious, but are stuck nonetheless. Any pointers much appreciated!

My OpenLayers code is:
			var map;			
				
			function init(){							
	  			var options = {
	      			projection: new OpenLayers.Projection("EPSG:900913"),
	      			displayProjection: new OpenLayers.Projection("EPSG:4326"),
	      			units: "m",
	      			numZoomLevels: 20,
	     			maxResolution: 156543.0339,
					maxExtent: new OpenLayers.Bounds(-20037508.34,-20037508.34,20037508.34,20037508.34)
	  			};

		  		map = new OpenLayers.Map('map', options);
				
		  		var gphys = new OpenLayers.Layer.Google(
		      			"Google Physical",
		      			{type: G_PHYSICAL_MAP, 'sphericalMercator': true, numZoomLevels: 20}
		  		);
				
				var wmslayer2 = new OpenLayers.Layer.WMS(
		           		"Speed Cameras",
		           		"http://localhost:8080/geoserver/wms", 
		           		{'layers': 'SPEED_CAMERA', 'format':'image/png', 'transparent':'true'},
		           		{'opacity': 1.0, 'isBaseLayer': false, 'visibility': false}
		      	);		        
				
		  		map.addLayers([gphys, wmslayer2]);

Cheers
Tobias

I dont suppose anyone has code lying around for creating a balloon popup 
when the KML is using balloon style and extended data to store the 
attribute data?

Subject: [OpenLayers-Users] measure control & google layer
Message-ID: <149706.48736.qm@web27401.mail.ukl.yahoo.com>

Hi all,
I'm using measure controls with google maps layer.
You can see my test page at http://webgis.iamc.cnr.it/webgis/prova/test3.html
As you can see, using measure tool, ther's a shift between cursor position and features.
Also, I save digitized features in a vector layer, and when I zoom out, features lost their original position.
There's many posts regarding the precision of measures, but I can't find nothing about this issues.... there's a way to solve this problem??

Thanks in advance

Marco

Hi,

I'm not sure, if it solves your problem. But i had the same error with my
application and I could solve it by adding to the map div style width:100%;
height:100%;

#map{
    width:100%;
    height:100%;
} 

With FF i hadn't a problem. And with OL 2.8 this wasn't needed.

Thanks for the suggestion, however, this did not work.  I'm still trying to
find a solution.

Thanks.

Hi Venkat and Anindya,

First, your questions (see below) are user questions and not dev 
questions so I have moved them over to the user list.

Second, your questions are very basic web development questions and not 
really OpenLayers specific. OpenLayers is a JavaScript library that runs 
in a web browser, so all the rules that apply to this development 
environment apply to OpenLayers.

  If you can not answer this question then you need to do more research 
and read some tutorials on web development BEFORE you start asking 
questions on OpenLayers User or the Dev lists. [2] So questions like, 
Can OpenLayers call .... can be more generally ask in terms of can any 
JavaScript web client call ... and how do they do that? Then you can 
look at the examples OpenLayers provides that do very simple things like 
you are asking. Once you have some basic understanding of OpenLayers and 
you need to more specific information, I'm sure there are plenty of 
people that are willing to give you some help.

If you are asking to decide if you should pursue some additional 
investigation on your own then:

1) Yes, OpenLayers can call AJAX services - see the examples [1].
2) Yes, OpenLayers has support for parsing various geostapial data 
formats - see the examples [1]
3) No Javascript running in a browser can talk to a Database without 
some kind of AJAX server application
4) All Javascript running in a browser can talk to web services as AJAX 
requests, but you have to deal with the "server of origin" issues. If 
you don't know what that means, google it.

Hi,

I was stuck up at the below implementations and am not able to move further.
I have few queries on OpenLayers functionalities, Please let me know the
possibility of the approach and the best way of implementing it !!

1. Can OpenLayers directly read the XML data with spatial information and
display in web page? If this possible, please give any example

2. Can OpenLayers connect directly to any database (oracle) and publish the
data on map? one way of connecting to the database is through the use of
GeoServer with OpenLayers. But I want to use only OpenLayers to connect to
the oracle database. Please let me know how to achieve this?

3. Can OpenLayers using JavaScript (AJAX) can call a Oracle BPEL webservice?
If so how to customize the openlayers to call the webservice

Regards
Venkat

Subject: [OpenLayers-Users] Marker + Popups = Flicker
Message-ID: <1273206982599-5017786.post@n2.nabble.com>


I'm using the GWT wrapper for Openlayers and I've pretty much got the same
code as seen in this old tutorial
http://geoserver.org/display/GEOSDOC/Google+Web+Toolkit+(GWT),+OpenLayers+and+GeoServer.
I want a popup to come up when I rollover a marker with the mouse. This
works but I get the worst flickering when the popup is visible and the mouse
rolls over the popup (which is just over the marker). I've tried offsetting
the popup but it's hard to judge where the thing is going to pop up
depending on where I'm looking at the map. I've changed to using a
FramedCloud cause it's a skinnier popup at the base (less of a problem) but
this isn't helping much. It just seems so random, sometimes it is perfect
sometimes it is absolutely horrible. My zoom level seems to affect it and
obviously whatever algorithm is the the background to determine which
quadrant the popup appears in.

I've tried overriding, registering/unregistering mouseover/mouseout events
but to no avail. Are there any straightforward solutions to this problem? It
is really bugging me.

Well thats a bit embarrassing, I think I fixed it - just passed in the
following for my popup constructor to offset the achor a little:

popup = new FramedCloud("marker-info", marker.getLonLat(),
                        new Size(120,80), "<p>" + getTitle() +  "\n" +
marker.getLonLat().lon() + "\n" + marker.getLonLat().lat() + "</p>" ,
                        new Icon("", new Size(16,16), new Pixel(-8,-8)),
false);

Previously I had new Icon("", new Size(0,0), new Pixel(0,0)), false);

Oh well, I hope my oversight helps someone!

No real help, just a bump. Got the exact same problem.
However, after closing the popup  it is reopened (??) as soon as I do some
panning, not necessarily panning it out of view first. (for ref:
panMapIfOutOfView is set to false). When it reopens, the size is correct...

||Our Application uses OL to draw features on a map, style them and save 
it in postgresql(attributes and style as json strings). After that then 
we load them as KML-files. With polygons and linestrings there is no 
problem, but with points. When they are styled like below they are not 
drawn when we load them.
Now I was looking for the reason and I found it, I think. It's when a 
point is styled not the default(or any other) value for pointRadius is 
used, am I right?
If there is no failure in my style than my proposal is to add the 
following line into the parseFeature-function of OpenLayers.Format.KML, 
right before
"var feature = new OpenLayers.Feature.Vector(geometry, attributes);":
if ((geometry instanceof OpenLayers.Geometry.Point || geometry 
instanceof OpenLayers.Geometry.MultiPoint) && 
this.styles[attributes.styleUrl] &&  
!this.styles[attributes.styleUrl].pointRadius) {
                 this.styles[attributes.styleUrl].pointRadius = 6;
     }
Or it could be a better solution to add the default as default to 6 in 
the parseStyle-function like(would save the if statement, but there 
would be more useless data in the style-objects):
style["pointRadius "] = 6;
It's a pity that in the parseStyle there is no access to the geometries 
use the style, but it's clear why it's like that.

Subject: [OpenLayers-Users] logical.OR filter
Message-ID: <013101caedda$65d98c90$318ca5b0$@green@ibstv.co.uk>

Hi All

 

I am using OL2.8 with a vector layer that uses WFS getfeature to obtain up
to about 20 features from a MapServer WMS layer. Each feature is found via a
comparison filter, all of which are then combined via a logical.OR filter.
It sort of works but I get inconsistent results from the logical OR filter -
generally I see one or two of the features only, not all of them. 

 

I see that there has been some problems with logical.OR in OL2.8, can anyone
tell me if moving to OL2.9 is likely to solve my problem?

 

 

Chris

Message-ID: <h2sfdd4fff71005070746w616e1156r6d1cc0c5ad6b93cb@mail.gmail.com>

Hello everyone,

I have a bug which I cannot solve. Was wandering if anyone could help.

I am trying to save a single point to a vector layer (this is originally a
shp file which I uploaded to GeoServer in two ways - as the shapefile itself
and as a postgis table, both of them produce the same error) following the
wfs-t example that comes with geoserver (geoserver/www/wfs-t.html).
When I try with the default page it works and saves the point to
topp:tasmania_cities.

Anyone has any ideas. I'm kind of in the dark. If you want any more info
about my data feel free to ask. I will answer immediately.

Thanks, Jo?o

Thank you so much for that link!

 

I did not need it to validate my kml file, but when I typed in my kml URL and got a 404-not found, that told me my proxy was not why I was getting a 404-not found error in my application.  That helped me to track down the error to kml mime type not enabled in IIS7 (windows hosting.)  While my host (GoDaddy) does not allow me to directly add mime types to IIS7, it can be done in the web.config file in my app directory as so:

 

<configuration>

<system.webServer>

<staticContent>

<mimeMap fileExtension=?.kml? mimeType=?application/vnd.google-earth.kml+xml?/>

</staticContent>

</system.webServer>

</configuration>

Hi Jo?o,

I noticed that the coordinates that get inserted seem to be in spherical 
mercator projection (or at least some projection that uses meters 
instead of degrees) without specifying the SRS in the WFS POST anywhere.
Try by either providing the correct projection or by converting your 
points to the projection your layer is in.

I hope that helps.

Subject: [OpenLayers-Users] Nodelist Info / GetFeatureInfo not working
Message-ID: <9D99985C-4EA0-40EC-AA5F-793BE11DF1CB@googlemail.com>

Hi,

I use the following example of geolayers to test GetFeatureInfo (it works, so this can be no proxy-issue, also OpenLayers and GeoServer run on the same server). But when I copy the (what I think) relevant parts into my own code, it is not working anymore (after clicking on the line the text switches from "Click on the map to get feature info" to "Loading... please wait..." and that's it). So it would be great to know what the minimum requirements for this method are? And if it is possible to limit the output to some properties of the layer?

Maybe the problem is the line

> QUERY_LAYERS: map.layers[0].params.LAYERS,

because I have more than one layer in my own map? 

Thanks for any help!

Hi,

Have you looked at the request that OL is sending to GS? The FireBug 
addin for Firefox has a 'Net' tab that shows you every request that your 
application sends, including what response it gets back.
That might help you find out what's wrong.

Regards, Roald

Subject: [OpenLayers-Users] Another GetFeatureWFS & (Possible) Proxy Issue -
	CONTENT_LENGTH
Message-ID: <1273361971808-5024916.post@n2.nabble.com>


Hi All,

I apologize in advance if this question is already answered in a previous
post. I have looked through many GetFeatureWFS (and proxy.cgi) related posts
and have not found a solution to my problem as of yet - and it doesn't help
that my coding skills have gone stale - so here goes....

I've been fiddling with the Openlayers WFS GetFeature capabilities for a
little while, but have been having a hard time getting any results from it.
At first, Firebug was giving me a lot of errors when I tried to select or
hover over features, but I quickly found out about the need for the
ProxyHost, and have downloaded the proxy.cgi from the Openlayers site and
placed it in my /cgi-bin/ folder. After a lot of work with it, I believe I
finally have that working - it's properly opening when directly referenced
(though It could still be failing for other purposes). 

Now when I try to select features from my map, I'm no longer getting any
'red errors' in Firebug, but nothing is being selected and I'm still seeing
some error messages (though no longer red) pop up in Firebug. The query
appears to be sent to the server, but this is what is coming up as the
response:

Some unexpected error occurred. Error text was: 'CONTENT_LENGTH'

Now, I'm guessing that I have something wrong with either my js or my proxy
(or even possibly my mapfile), but I can't seem to find where the problem
is. Anybody  have any ideas?

As for the environment details:

I'm currently running my website on a Ubuntu 8.04 machine with Apache
version 2.2, and am referencing the newest version of OpenLayers from their
site. I will post the web and proxy code below, but if someone wants to play
in my sandbox, please go right ahead : 
http://www.cemetermaps.ca/Simpletest.html
www.cemeterymaps.ca/Simpletest.html . It only appears to work for Firefox
right now - not IE. That's a completely separate issue that I will tackle
later on .

Any help would be appreciated - please let me know if you have any
clarification questions for me.

Thanks,

Chris

Subject: [OpenLayers-Users] Raster map shift - solved
Message-ID: <4BE69A0C.1030409@weykam.net>

A couple of weeks ago I notified strange raster layer behaviour and I 
would now like to share with you how we solved the problem:

We observed a slight shift when the raster layer was displayed in 
OpenLayers. The shift seemed to be dependent on scale and GetFeatureInfo 
requests were not affected. That means that, although the pixel class 
was not the expected one, the returned value was always correct. We did 
not observe this behaviour in the thick client we use to check our map 
services and therefore concluded that the underlying WMS was correct and 
that the shift had something to do with how OpenLayers displays raster 
layers.

And the end it turned out that the test client did not display the layer 
correctly either ? we just happened to look at a scale where the shift 
was very small. So, OpenLayers was off the hook and we went back to 
MapServer. We finally changed the configuration to allow non-square 
pixels - the raster layer pixels are defined in decimal degrees and thus 
are irregular.
For those who have been working for years with MapServer and didn?t even 
know that this parameter existed, this did the trick:
CONFIG MS_NONSQUARE yes
According to the manual, this should be the default, but it seems that 
MapServer doesn?t always ?remember? this.

Now everything is back in place. Thanks, Bart, for the hint.
Kind regards,
Stefanie

Hi Roald,

I added this tool and loaded the page again. Unfortunately the response is empty. What could be the reason for this?

Thanks, Pascal

But when I copy the (what I think) relevant parts into my own code, it is not working anymore (after clicking on the line the text switches from "Click on the map to get feature info" to "Loading... please wait..." and that's it). So it would be great to know what the minimum requirements for this method are? And if it is possible to limit the output to some properties of the layer?

Subject: [OpenLayers-Users] drawing a polygon over selected region
Message-ID: <1273413819773-5026619.post@n2.nabble.com>


Hi Friends,

I am doing a GETfeature over a WFS layer.I am able to get the info of
selected features.
I have 2 questions:

1) When I drag the mouse a box is drawn temporarily and it goes off as soon
as I leave the mouse..
I want to pass the bounds of the selected region drawn to a function which
will draw a rectangle with a particular style over the selected region.How
can I do this?

2)I want to save the details of the features selected i.e within the box in
a GML.
3) Can we have a circle instead of a box for selection?

My code is :

layer = new OpenLayers.Layer.WMS("OpenLayers WMS",
"/Mapserver/mapserv.exe?map=c:/ms4w/apache/htdocs/Shape/newwr1rec.map", {
layers: ["state", "RailwayStations"], transparent: false, format:
"image/png" }, { isBaseLayer: true });
               map.addLayer(layer);

               layer = new OpenLayers.Layer.WFS("MyWFS",
               
"/Mapserver/mapserv.exe?map=c:/ms4w/apache/htdocs/Shape/Rail_wfs.map",
                { typename: "RailwayStations", maxfeatures: 100 },
                { featureClass: OpenLayers.Feature.WFS });
              
                select = new OpenLayers.Layer.Vector("Selection", {
styleMap:
                new
OpenLayers.Style(OpenLayers.Feature.Vector.style["select"])
            });
//                select1 = new OpenLayers.Layer.Vector("Selection1", {
styleMap:
//                new
OpenLayers.Style(OpenLayers.Feature.Vector.style["select"])
//            });
//            
            map.addLayers([layer,select]); 
               map.addControl(new OpenLayers.Control.LayerSwitcher());
               map.setCenter(new OpenLayers.LonLat(lon, lat), zoom);
               
               // make a GetFeature request
//               map.events.register('click', map, function(e) {
//                   var url =
"http://localhost:81/cgi-bin/mapserv.exe?map=c:/ms4w/apache/htdocs/Shape/Rail_wfs.map&SERVICE=WFS&VERSION=1.0.0&REQUEST=GETfeature&typename=state";

               //               })

               control = new OpenLayers.Control.GetFeature({
                 
                   protocol: OpenLayers.Protocol.WFS({

Subject: [OpenLayers-Users] doing a search with a buffer
Message-ID: <1273414644678-5026652.post@n2.nabble.com>


Hi Friends,

I want to do a search with a buffer.
My scenario is like this.
I get a structure Id from the user and using that I get the geometry of that
structure from the postgres DB.
Now I want to do a search of all structures within a radius of say 100km
from the structure selected by the user.
Is there any postgres function which will give the geometry of all features
lying within a certain radius of a feature..

Has anybody done something like this before?If yes pls share as to how you 
have done it?

Thanks for your attention.

Subject: [OpenLayers-Users] custom bitmap as main background layer
Message-ID: <1E355A16FF9848E8A909547ABE8F8360@geog.local>


Hi All,

I am using a custom bitmap (878 x 823 pixel) as openlayer main background layer and I get the openlayers map display that I want (http://www.oifii.org/imt/dai/src/2010may31/index_CRCM_POLSTE-BITMAP.html).

I would like to be able to do coordinate (projection) transforms. Provided my bitmap is a stereo polar projection rotated in order to get north america vertical and center to canada, how could I modify my code here below (that works in pixel projection) to work with this specific projection? I need to do this because I want to overlay objects from a layer that I must query in lat lon (EPSG:4326).

My code used to create the default layer is:

minimumdefaultBounds=new OpenLayers.Bounds(0, 0, 1, 1);
defaultBounds=new OpenLayers.Bounds(0, 0, 878, 823);
var options= 
{
 minResolution: "auto",
 minExtent: minimumdefaultBounds,
 maxResolution: "auto",
 maxExtent: defaultBounds, //i.e. max bitmap size 
 restrictedExtent: defaultBounds, //null to allow panning
 projection: myproj,
 controls: [new OpenLayers.Control.MouseDefaults(),new OpenLayers.Control.ArgParser(),new OpenLayers.Control.PanZoom()]
};  
map=new OpenLayers.Map('map',options);




Regards,

Stephane

Hi Pascal,

You should pretty much always get at least *something* back: either an 
error or an empty reponse (FireBug would tell you). Have you really got 
":80" in your settings like below?

     OpenLayers.loadURL("http://myownhomepage.xyz:80/geoserver/wms", 
params, this, setHTML, setHTML);

If your Tomcat runs on port 80 then you can leave out the port number. 
That might do the trick (and yes, it would then have been a proxy 
issue). Like this:

     OpenLayers.loadURL("http://myownhomepage.xyz/geoserver/wms 
<http://myownhomepage.xyz:80/geoserver/wms>", params, this, setHTML, 
setHTML);

And since your OL is on the same server as your GS, you could even do this:

     OpenLayers.loadURL("/geoserver/wms 
<http://myownhomepage.xyz:80/geoserver/wms>", params, this, setHTML, 
setHTML);

And to deal with errors in your AJAX request, why not use a separate 
function like this:

     OpenLayers.loadURL("/geoserver/wms 
<http://myownhomepage.xyz:80/geoserver/wms>", params, this, setHTML, 
*onAjaxError*);

Regards, Roald

Hi,

 From your other post ('drawing a polygon over selected region'), I 
assume that you're using MapServer. You can quite easily add a spatial 
filter to your WFS request.


            var radius = 100 * 1000; // 100km

            // create point from your lat and lon of your selected feature
            var radiusPoint = new OpenLayers.Geometry.Point(lon, lat);

            var radiusFilter = new OpenLayers.Filter.Spatial({
                 type: OpenLayers.Filter.Spatial.DWITHIN,
                 value: radiusPoint,
                 distanceUnits: "meters",
                 distance: radius
             });

             // assuming this is your vector layer
             layer.filter = radiusFilter;

That should do the trick. Note: if you want to do something similar with 
GeoServer, please note that GS can only use the native distanceUnits for 
that layer. If that layer has degrees as its units, you'd need to 
convert your units from meters to degrees.

Hi. We do that in MapFish using the && operator, and the expand and
distance functions. See [*]. Hope it can help.

The handler that is activated last should be triggered first.

This makes sense to me.

How can I ensure that the feature click handler control is able to stop the propagation to the map click handler, preferably regardless of the order in which they are added to the map?

AFAICT you need to activate the feature handler last. You also need to
set stopClick to true in this handler. And you may also need to set
stopDown and stopUp to true in this handler.

So far as I can tell, I can't use that--my features are points with large, mostly transparent icons that tend to overlap and cover the whole map (in which case SelectFeature intercepts mousedowns on the whole icon and makes drag-panning impossible), therefore I only want to respond to clicks near the center (canceling propagation in that case). If someone can tell me how to make that work with SelectFeature, I'd be glad to use that instead.

You could possibly use two point features, with one dedicated to
feature selection.

Hi,
thanks for the link Carlos. I checked my files and the result is now 
"Errors  = 0 Recommendations = 0 Suggestions = 0  The KML file is valid 
and complies with best practices.", but the points are not drawn in OL, 
except I add the lines from the first mail into the 
OpenLayers.Format.KML. Is it possible to add it generally to the 
OpenLayer.Format.KML that the radius of point is default 6 or should we 
make an own solution by edit the file on every update? It's a similar 
behaviour like Google Earth whitch has also an default pin for points, 
but in openlayers it's default the default Point (circle with default 
radius of 6).
Regards
Slawomir

Subject: [OpenLayers-Users] Wms authentication problem.
Message-ID: <AANLkTikuW_peMaP5h-fTWo1bCxuUtjGi27fAYkfhoGNH@mail.gmail.com>

Hi all,

I am using normal wms layer request like:

mapThis = new OpenLayers.Layer.WMS("Basemap", "
https://username:password@www.kartta.fi/image",
            {layers: 'perus',
                singleTile: true,
                srs: 'EPSG:4326',
                format: 'image/png',
                styles: ['style_1'],
                transparent: false
            },
            {isBaseLayer: true});

My problem is that this authentication "
username:password@www.kartta.fi/image" is not working how I would like. It
is still asking everytime username/password when I reload map or when I
remove map. (Browsers box that asks username/password)

So I am asking that what is right way to handle this wms authentication ?

Br.

	type capability
Message-ID: <F17292B1-AAE5-4194-B0CC-0293F0BB7438@lhsw.com>

Hi all. I'm new to the list (as well as openlayers) and have some hopefully rudimentary questions.

First, can someone explain or point to an example that shows how to extend ModifyFeature to visually select features as you mouse over them like you can with the SelectFeature? What I want to do is visually highlight them as I mouse over them (as well as display some detail about them in a layer) but not actually select them (ie put into edit mode) until I click on them.  Once they are truly selected I want them to stay highlighted while being edited/moved (I am working with points).

I have tried setting hover = true for the ModifyFeature, as well as create my own SelectFeature and set the modifyFeature.selectControl to it but when I do that, the ModifyFeature behaves like a SelectFeature only.

thanks,
charles

Message-ID: <1273514537091-5032030.post@n2.nabble.com>


There seems to be some pretty significant differences between the hierarchy
of the context that is returned after the read_wmc_Layer function is run in
OpenLayers 2.8 vs. 2.9. 

In 2.8, there is actually a layer created with params and options attached.
In 2.9, there seems to be only an associative array added to a
"layersContext" object that doesn't have a layer in it at all.

Can someone point me to some documentation that discusses the changes
between the two versions? Perhaps a mapping chart to tell me where I will
find the pieces of information imported now? For example, in 2.8, a lot of
the layer's Server information was placed in the params object under
layerInfo. In our code, we needed used the Server's title attribute from our
WMCs as well, and extended the Format read to read that title attribute and
append it to the layerInfo.params object as well. Now, it's looking like I'm
just appending title to the layerContext object and I'm uncertain what other
things are found in that object. Is the layer's title already in there?

Also, how does the layer itself get created now if the Format read isn't
doing so? 

Basically, 2.9 appears so completely different from 2.8, I can't get it to
work for our application anymore and am facing a pretty significant re-write
to adjust. The fact that I can't find anything in any documentation (release
notes even) that mentions that it is happening is a little frightening.

Hi,

most of the changes are descirbed here,

http://trac.openlayers.org/ticket/2251

however there should not be any *API* changes, but it seems your usage was the internal structures and not the API right?

Best regards,
Bart

Yes, that's correct.

Hi Charles,

You could achieve what you want be creating a SelectFeature control with 
highlightOnly:true for "highlight and display info" and a standard 
ModifyFeature control for the second one. By registering 
"featurehighlighted" on the first control should allow the display of 
the hovered feature info.

The following example should be of great help :
http://www.openlayers.org/dev/examples/highlight-feature.html

You could toggle on/off the highlight control when editing, but that's 
up you.

Regards,

Alexandre

I made a complete new setup and found out that the enconding of one file was not the right one. Now I can use the GS example anywhere on my site and it works.

It is strange now but there is no request in Firebug. When I click on the map the text switches to "Loading please wait" and that's it. Maybe the problem is because of the different layers?

Thank you very much for your help!

A lonlat, as a lonlat and a point both represent a geographic
location. A lonlat isn't a shape and cannot be drawn.

A pixel represents a position in the map div, its x and y values are
expressed in pixels.

A Map object exposes method for converting a pixel to a lonlat and vice-versa.

OpenLayers could indeed include a Geometry.Point.fromLonlat conveniene
function or something, but it currently doesn't have such a function.

Have you tried setting "projection" to "new
OpenLayers.Projection("EPSG:4326")" in your vector layer so OpenLayers
reprojects your KML data to your map projection?

Dear User-list
 
Can any anyone advise as to the best OpenLayers layer type to use to access an ArcGIS Server 9.3 or 9.3.1 tiled map server cache? i.e. equivalent to using the esri.layers.ArcGISTiledMapServiceLayer layer type in the esri Javascript API?

I have tried both OpenLayers.Layer.WMS and OpenLayers.Layer.ArcGIS93Rest which work, but don't appear quite as fast as using the Esri version above. 

There was a patch submitted some time ago: http://trac.openlayers.org/attachment/ticket/1967/ArcGISCache.patch 

There is also OpenLayers. Layer.XYZ which I haven't tried.

Many thanks,

Robert Sanson

                        kmlSelectControl.events.on({
                                 "featurehighlighted": onKmlFeatureSelect,

                        kmlHoverSelectControl.activate();
                        kmlSelectControl.activate();
kmlLayers is array of layers (in this case kml). Order matters. 
HoverSelect control , the SelectControl.

With this, I highlight features as you mouse over, then select on click.

Subject: [OpenLayers-Users] Marker and vector mouse over events
Message-ID: <AANLkTilr7JYSmL_ikH6jqH6ztzlYsoG1TTiINbAbH9SJ@mail.gmail.com>

Hi,

 I want to ask two questions:

I have to use one marker layer and I found some examples to ?do? something
on mouseover and on mouseout. Something likes that:

var marker = new OpenLayers.Marker(punt,icona);

 marker.events.register("mouseover", foo_var, method2);

 marker.events.register("mouseout", foo_var, method2);



And I also have to use one vector layer, but I only found the SelectFeature
solution to do the same:

selectControl = new OpenLayers.Control.SelectFeature( [layer1,layer2],
{onSelect: onFeatureSelectMethod,onUnselect:onFeatureUnSelectMethod, hover:
true});

map.addControl(selectControl);

selectControl.activate();
But this second way it?s not working so fine as the first one. Is there some
possibility to use mouseover and mouseout events in vector layers?


Another question, not so important, I use  OpenLayers.Request.GET method
calling a php file, but in this one I can?t access to SESSION variable. I?m
doing it right?

OpenLayers.Request.GET({url:'file.php',params: {"lon":
feature.geometry.x,"lat":feature.geometry.y},success:successMethod,scope:feature,failure:function()
{alert('Something wrong happenned?);}});



Thanks a lot!

Message-ID: <201005111010.57616.schroete@iup.physik.uni-bremen.de>

Hello,

we have several WMS Layers some  of which are expensive (in machine cycles) to render raster images. We do observe that each time the Browser Window is rezised or the user pans/zooms a WMS request is generated for every zoom/pan/resize level.

Is there a possibility in OpenLayer to supress the rerendering or the newly generated WMS requests till the zoom/pan/resize comes to a halt for certain period of time ?

The situation now could bust the server if someone has a nervous hand on the mouse ...

Thanks and Regards
Heiko

Hi Heiko,

How are you serving your WMS layers?  Can't you just use tiling in
OpenLayers and cache the tiles on the server (like GeoWebCache)?  This
should solve your resizing problems and your slow rendering...

Hi Jon,

thanks for your reply. The raster images are so called "gridded" imeges of satellites measurements.
They have to be done globally and are created on the fly taken the data points from a PostGIS db.

Hence every zoom/pan/resize action triggers the data request and the creation of the "gridded" raster image.

That is the reason why i'am trying to delay the creation till the zoom/pan/resize interaction comes to an halt.

Thanks and Regards
Heiko

Ah, I think I understand.  You could still look into client-side tiling
though.  The data will still be created on the fly, but it won't make a new
request every time you pan or resize.

I assume you're generating your data on the fly because it's frequently
updated, if so how often?  Is it not possible to use caching, but clear the
cache every so often?  That might take some strain off your server.

The gridded images are created on special request by mouse clicking a button.

But once this special WMS layer is activated it is handled the same way OpenLayer treats ordinary WMS layers. Once the image is created displaying it is no problem at all.

The generation or "gridding" routine is the expensive procedure.

I cannot see that tiling would help us because it is not the image itself which causes the problem but the generation of it.

Message-ID: <8A8A884BC27BED439849DAB50639D302010819DD@gemini.amlin.com>




Hi All,

 

I have a series of draw controls which all have the 'featureAdded'
property. When the user has drawn a polygon, or a line etc and then
zooms in or out, the vector feature disappears.  It doesn't happen when
the user pans, or if I remove the 'featureAdded' property.

 

Is there anyway to resolve this problem?

 

Thanks in advance for your help!

Hello

I had to do an intervention on a project using google projection 
(epsg:900913).
That projection is supposed being metric, but to be able to get correct 
measurement values (in meters) with the OL Measure control, I had to specify 
"geodesic" as true in the controler's config.

why ?
is the google projection metric or not ?

thanks in advance

The projection uses meters as distance units, yes. But like with every projection, measuring lengths is only accurate at some very special places. For Spherical Mercator, this is along the equator. Mercator projections are optimized for measuring angles, which is important for nautical purposes. Other projections are optimized for measuring areas, which is important for cadastral maps.

Anyway, the more you move away from the equator in Spherical Mercator, the less accurate your distance measurements get. And "geodesic measurement" is nothing else but measuring on the spheroid instead of the projected map.

Regards,
Andreas.

	made of square features with labels
Message-ID: <AANLkTimtmzNFNjRYzFJOalynuOnx9KC7u0aVEgD5YAHL@mail.gmail.com>

Hi,
I'm experiencing some problems using a vector layer as an overlay for a map,
when this layer is rendered with IE7-8.
The basic problem is that the operation of adding and rendering this new
layer is performed very slowly on IE when this layer, made of some squares,
has labels in its StyleMap.

I'm wondering if anybody else has ever experienced something similar. You
can find a full description of this bug (with a working example that
reproduces the issue) here:

Thanks in advance for the attention,

Hi,
     I'm trying to display a popup on mouse over GPX track. This is the

var lgpx = new OpenLayers.Layer.Vector("Track", {

strokeOpacity: 0.5},
                 projection: map.displayProjection,
                 strategies: [new OpenLayers.Strategy.Fixed()],
                 protocol: new OpenLayers.Protocol.HTTP({
                     url: 'gpx.php',
                     format: new OpenLayers.Format.GPX()
                 })
             });

             map.addLayer(lgpx);

             lgpx.events.register('loadend',lgpx,function() {
                 var bounds = this.getDataExtent();
                 map.zoomToExtent(bounds);

             var hoverSelect = new OpenLayers.Control.SelectFeature(lgpx, {
                 hover: true,
                 onSelect: function(feature) {

--------------> Here I want to display a popup with info from the GPX file

                 },
                 onUnselect: function(feature) {
                         if (feature.popup) {
                         map.removePopup(feature.popup);
                         feature.popup.destroy();
                         delete feature.popup;
                     }
                 }
             });
             map.addControl(hoverSelect);
             hoverSelect.activate();

I cannot find a way to get the currently selected track segment and 
extract attributes to display inside the popup.

Any idea?

Tnx

I use eventListeners instead of onSelect onUnselect.

Hi everybody,
is it possible (or how to do) to get a tile level/x/y url from mouse move
events?

I look at MousePosition control and I know how to get lat/lon from pixel,
but that it all.

Thanks in advance for any help.

Hi Roald,

Thanks for your reply.
If I have the center point of the selected region then your code will do the
rest.
But the problem is that when the box is drawn using the GEtFeature control
it is not possible to get center point of the selected region or the bounds
of the selected region.
If either of these were available then it would have been possible to draw a
layer over the selected region.(this is wrt 'drawing a polygon over selected
region').

w .r.t this post I have a structure ID using which I can get the geometry
from the postgres table.Since I get this geometry on the server side I need
to get the other geometries and their attributes on the server side as well.

I am not sure how get feature can help me when my selected geometry is on
the server side.
As far as I know getfeature works only when I select multiple features on a
wfs layer.
Is it possible to pass the geometry to getfeature control and get other
feature details within a certain radius.

Thanks.

I'm having an issue with specifying rotation for one of my features. It's a
point feature with a externalGraphic specified, and the center of rotation
of the feature seems to be initially set to the feature's own Point.

However, when I programmatically *move* the feature, the center of rotation
doesn't move with it, and the feature's rotation against an external center
causes it to be way off-position.

I've tried implementing the move both by updating the x and y fields
directly in the Point object itself, and also by using the Feature.move
function. Neither has the desired effect?using the Web Inspector, I can
clearly see the SVG element and the rotation is being specified in (angle,
cx, cy) form.

As a last resort, I'm willing to use external JavaScript to find the element
and manually insert the rotation which I require, but is there some way to
do it "properly" using OpenLayers' own rotation stylings?

Thanks,

Mike

Subject: [OpenLayers-Users] OpenLayers.Layer.XYZ - not applying tileOrigin?
Message-ID: <4BEAA0C2.379F.0037.0@asurequality.com>

I seems to be having a problem with OpenLayers 2.9.1 not calculating the
correct tile. Our ArcGIS server cache starts its origin way up north
(19998100) and west of our max extent (-4020900), so the start tile for
resolution 0 is .../tile/0/16/6, but OpenLayers is sending a request for
...tile/0/0/0
 
Here is my code:
 
var mapoptions = {
                maxExtent: new OpenLayers.Bounds(1018697.71047,
4674128.11975, 2568710.79993, 6296981.53325),
                resolutions: new Array(3175.0063500127,
793.751587503175, 264.583862501058, 198.437896875794, 132.291931250529,
66.1459656252646, 26.4583862501058, 19.8437896875794, 13.2291931250529,
9.26043518753704, 6.61459656252646, 5.29167725002117, 3.96875793751588,
2.64583862501058, 1.98437896875794, 1.32291931250529),
                tileOrigin: new OpenLayers.LonLat(-4020900,19998100),
                tileSize: new OpenLayers.Size(256,256),
                units: 'm',
                projection: new OpenLayers.Projection('EPSG:2193'),
                fractionalZoom: false
                };
                var map = new OpenLayers.Map( 'map',mapoptions );
                
                var topoxyz = new OpenLayers.Layer.XYZ( "Topo",
                   
"http://ws-esrimt/ArcGIS/rest/services/mapservice_topography_vector_prod/MapServer/tile/${z}/${y}/${x}",
                   {isBaseLayer: false, sphericalMercator: false});
 
Any way I can get OL to calculate the correct offset?
 
Many thanks,
 
Robert

This sounds like an issue we had in OpenLayers 2.9, but was fixed in 2.9.1. Make sure you are using the latest version.

Andreas.

Subject: [OpenLayers-Users] Displaying WCS like a WMS
Message-ID: <AANLkTinakugoXo4qFuSXZRwUWbri_dZmxc33SvJWeEIE@mail.gmail.com>

Hi,

I was just wondering if anybody has tried displaying WCS data in OpenLayers?
 I was thinking that it could be treated as a WMS if you choose a
web-friendly output format, it would also allow thing like band selection.

Has anybody managed this?

Thanks,

Jon

Subject: [OpenLayers-Users] WMS layer redraw problem
Message-ID: <4BEAA0AE.1040506@gis3w.it>

Hi all,

I build a webgis editing  application with OL 2.8, all work fine, but 
I've a problem with redraw wms layer background:

In my application I edit several layers during the editing mode... but 
on simple watching mode I show that layers like wms layer (by 
mapserver...)... after a layer editing action I invoke a 
wms_layer.redraw(true) method... but  I think for browser cache, the 
layer is redraw... but single tile doesn't change ad so for to see the 
changes I've to pan the map until the layers wms are redraw....

I hope you could understand my problem...

Someone had similar problem??

Thanks in advance
W

Subject: [OpenLayers-Users] How to Use selectControl and dragFeature control
	at the same time?
Message-ID: <AANLkTinKly6IQJcYATuu0FZQswlHjZPLdajb6xlC69mB@mail.gmail.com>

Hello All, i am working to achieve following,
1. Click to add a vector feature with custom icon and label at the point of
click (Completed)
2. Click to select any drawn feature and delete it (Completed)
3. Click to select any drawn feature and Modify it. ( By deleting and
re-creating the a new feature at the same place with new icon and label)
(Completed)
the code is posted below. Now the only problem i am facing it is as follows:

When ever i activate the dragFeature  control, the icons (Vector features)
become drag-able, but i cannot select them any more. My desired
functionality is heavily dependent on the select feature, as only after
selection i can modify and delete the features. How can i work around this
problem? Any suggestions are welcome.

Also, is it a good practice to Edit a feature as in point 3? , is there a
better way?

Thanks in advance.

Message-ID: <AANLkTimVUJa2VrQia-cZxzlvR0oPoir0s5aDFG0Ooyqw@mail.gmail.com>

Hi everyone,

I want to know if it's possible to control what is caching by the browser.
It's possible to free cache (memory) of OL ? Because when I use for a long
time my application firefox take 600 000 KO of memory

Thanks

Subject: [OpenLayers-Users] Custom TMS layer shifted to the north
Message-ID: <182003.8086.qm@web23001.mail.ird.yahoo.com>

Hi together,

I've set up a small test page to integrate a custom TMS Layer into OpenLayers. The tiles are displayed correctly but when I place a marker on the map it is placed north of the real position. Example:

http://www.uecmoedling.at/maptest.html

Mapnik layer is shown by default: shows the correct position
when switching the layer you get to a position which is exactly to the north of the real position

Maybe anyone can give me an hint which parameters I need to adjust to fix this shifting? I tried to modifiy the north/south bounds but this resulted in the marker changing position depending on the zoom level.

I got the following information from the people how manage the tile server but I don't know exactly what to do with these infos to make it work in OpenLayers:

The number of grids at a given zoom level is: gridWidth = 2^zoomlevel
The (earth) radius for the Mercator map projection is calculated as radius = (gridWidth * tileSize) / (2.0 * PI) where tileSize=256.

The x and y grid indexes are given by the calculated Mercator coordinate divided by the tile size:
    xGrid = xCoordinate / tileSize
    yGrid = yCoordinate / tileSize

Mercator coordinates will range from 0 through (gridWidth * tileSize).

The origin for the grid coordinates is at 180? W (false easting = radius * PI), and approx 85? N (false northing = -radius * PI), with x increasing toward the East and y toward the South. The scale (mpp) is determined by scale = radius * 2.0 * PI / (gridWidth * tileSize)

Other customers use an inverse flattening value of 298.257223563; so the projection is actually Mercator-ellipsoidal.

Thanks very much,
Michael

Hi. redraw(true) is supposed to do the job. Could you please post a
simple example demonstrating the problem?

I have found that the most reliable way to avoid browser caching when I want
to force a redraw of a WMS layer is to do something like this:

wms_layer.mergeNewParams({'timestamp':datetime});

If you append the current timestamp to the layer each time you want to do a
redraw it will have a unique address and thus bypass browser caching. If you
do this you will not need to utilize the OpenLayers redraw function.

You should "tell" OL to extract the attributes. There's a parameter to
set, see my example code.

In my code it is:
f.feature.geometry.getBounds().getCenterLonLat()

Related question?

Say that I have multiple objects that I'd like to be able to rotate
independently of each other. It seems like the tool for the job is the
substitution engine found in OpenLayers.Style. Currently, I'm just setting
the symbolizer directly on each of my features, so my question is, is it
possible to take advantage of OpenLayers.Style without having to deal with
the complication and complexity of OpenLayers.StyleMap?

I attempted to wrap my style hashes in the OpenLayers.Style class and then
pass them into the Feature constructor as before, but it didn't display
anything at all.

As an alternative, I could just create a per-Feature clone of the style hash
("symbolizer"), and inject my rotation parameter directly into each one, but
this seem inelegant.

What would be the best course of action?

Message-ID: <1273736961668-5045091.post@n2.nabble.com>


Hello friends!

How can one list all the features (for example, road-lines with the
attributes) in a wms layer?

It is easy (more or less) to perform it in wfs; but, how can we do that in
wms? (GetFeatureInfo returns information about features located on the
clicked point but it doesn't answer to my wishes. I need ALL the features in
a layer)

Regards!

redraw(true) calls mergeNewParams but uses Math.random instead of datetime.

Subject: [OpenLayers-Users] Toolbar icons IE6 transparency problem
	[SOLVED]
Message-ID: <224DBDAF88A6AC47BD22432815351BE007F1FF89@nekaposta1>

 
Ok, my mistake. Just when I sent the email I figured out what could be the problem. The problem was that the icons were in png 24bit format, so I've changed them to png 8bit format and now is working. 

Regards.

See attached image.

Any ideas?

Hi,

That's not the intention of WMS.

WMS does not allow to request all features from a server. If the serverside
wants to deliver all the data, then they have to setup a wfs.

Or if it's your own server and you use MapServer, then it could be possible
with a MapServer CGI-request.

Regards,
Arnd

Betreff: [OpenLayers-Users] List features in WMS


Hello friends!

How can one list all the features (for example, road-lines with the
attributes) in a wms layer?

It is easy (more or less) to perform it in wfs; but, how can we do that in
wms? (GetFeatureInfo returns information about features located on the
clicked point but it doesn't answer to my wishes. I need ALL the features in
a layer)

Regards!

Subject: [OpenLayers-Users] rectangle - resize from one corner whilst
	opposite is fixed
Message-ID: <1273753153781-5045810.post@n2.nabble.com>


Hi,

Hopefully i didn't miss this one elsewhere in the forums....

At the moment our resizing of a rectangle means that if i drag one corner
outwards then the opposite corner moves out in the other direction.

For practical purposes, it would be good (as an example) to move my
rectangle so the top left corner is where i want it and i can drag the
bottom right to the overall coverage i need.

At the moment, to do this i would get the box so the top left is close, drag
out the bottom right, move so top left closer again and do this as a loop
until i had the rectangle close enough.

What would be even better is to be able to drag any of the four corners
whilst the opposite corner stays fixed.

Anyone done this before? Apologies again if i'm missing the obvious

Thanks

Andy

	render
Message-ID: <1273763807000-5046572.post@n2.nabble.com>


Dear all

I am trying to render a vector layer from Geoserver using the WFS protocol
onto my British National Grid (EPSG:27700) map as follows:

    var wfslayer = new OpenLayers.Layer.Vector("WFS", {
        strategies: [new OpenLayers.Strategy.BBOX()],
        protocol: new OpenLayers.Protocol.WFS({
            url: "http://d2.elgin.gov.uk/geoserver.2/wfs",
            featureType: "NSG_STREET_PUBLIC",
            featureNS: "http://www.elgin.gov.uk/",
            featurePrefix: "e",
            geometryName: "GEOM"
        })
    });
    map.addLayer(wfslayer);

But it's not rendering. In Firebug, I see that the XML response looks good.
In fact, if I save the XML and add it to the map as a GML layer as follows,
it renders perfectly:

    var gmllayer = new OpenLayers.Layer.GML("GML", "nsg_street_public.xml")
    map.addLayer(gmllayer);

Does anyone have any ideas what I'm missing here?

Thanks, in advance,
Stuart

BTW, when I save the response GML to file, I have to remove the XML

OpenLayers.Layer.GML().

Subject: [OpenLayers-Users] Style issue with LayerSwitcher
Message-ID: <AANLkTikEBouJfWPG9wocpMG42D3JbTZnxXxrfJMuNiK6@mail.gmail.com>

Hi all, I am having a problem with the CSS styles on my html page in
which the OpenLayers map is in. Basically our graphic designer made a
run that all text in the div, p and body tags are to be black and
obviously the LayerSwitcher is inheriting that rule. No matter what I
do I cannot override it. This is what I added to the CSS:

div.olControlLayerSwitcher {
  width: 250px;
  color:#ffffff;
}

And nothing. I can see in Firebug that this piece of code is in fact
overriding it:

body, p, div
{
	font-family: "Helvetica Neue", 'Helvetica', sans-serif;
	font-size: 14px;
	line-height:20px;
	color:#000000;
}

Anything I am doing wrong or could try?

THANKS!

OK. I have managed to render my data using OpenLayers.Layer.WFS() but
according to [1] this is deprecated, so I'd really appreciate any hints to
get the Vector() route working.

    var wfslayer = new OpenLayers.Layer.WFS("WFS",
        "http://d2.elgin.gov.uk/geoserver.3/wfs",
        { typeName: "e:NSG_STREET_PUBLIC" },
        {
            typename: "NSG_STREET_PUBLIC",
            featureNS: "http://www.elgin.gov.uk/",
            extractAttributes: true,
            srsName: "EPSG:27700"
        }
    ); 
    map.addLayer(wfslayer);

Try to set the following on the drag control:

dragFeature.handlers['drag'].stopUp = false;
dragFeature.handlers['drag'].stopClick = false;
dragFeature.handlers['feature'].stopDown = false;
dragFeature.handlers['feature'].stopUp = false;

Thank Eric and Nathan,

I found the solution... It was a my mistake: when I save the 
new/modified/deleted feature vector I send the informations by
several ajax calls, but in a stupid manner I did it by async mode... so 
the layer refresh at the end of all calls something happened before 
database data saved!!

Sorry for my post... and thanks a lot!!

Walter

This can be caused by memory leaks. But in most cases it is just because a debugger (e.g. Firebug) is active when running the application. You should run your application without a debugger active, and if the memory footprint still increases, it is likely because of memory leaks (which can be in your application, but also OpenLayers is known to have some).

Andreas.

Hi,

What you want is more difficult than I realised. If you can retrieve the 
geometry of the feature you are interested in, you could use that in 
your filter (instead of the point). Have a look at the getfeature-wfs 
example on how to do that [1]. If you cannot retrieve your geometry it's 
going to be harder.

I don't know if you can tell your WFS server to use the geometry of a 
certain feature for your spatial operator (like: give me all features 
from layer X within a buffer around this feature from layer Y (or are 
all features in the same layer?)). Maybe somebody else can shed a light 
on whether this is possible? I'm sure you could do it with a WPS server, 
but that adds extra complexity.

Regards, Roald

Hi Pascal,

Are you sure your index.html is on server 'myownhomepage.xyz' and the 
same port? If so, you should be able to reference your geoserver with 
'/geoserver/wms'. If not, you need to use a proxy script or make sure 
that they are all on the same server and port.

Regards, Roald

Mh. Good question. Well, maybe not. But I don't think anybody has ever investigated potential leaks in Firefox. According to http://dbaron.org/mozilla/leak-monitor/, no web application should be able to cause memory leaks in a browser. If it does, then it's a bug in the browser.

Hurray, the code suggested by you works great :-)
Here is the final code which can achieve following:
1. Click to add a vector feature with custom icon and label at the point of
click (Completed)
2. Click to select any drawn feature and delete it (Completed)
3. Click to select any drawn feature and Modify it. ( By deleting and
re-creating the a new feature at the same place with new icon and label)
(Completed)
4. Drag Any selected or un-selected icon. (completed with the gracious help
of Mr. Ilya Braude, All credit goes to him)

My next goal is to save this layer  as kml. Hope i will post results soon

----------------the Code is as following- Sharing with every one in the hope
that sme one can benefit from it    -------------------------

Hi,

If the size of the images are reasonable, then the easiest way is to use an
OpenLayers.Layer.Image.

Set the map with your Gauss-Kr?ger projection, add a baselayer and then your
image layers (with yourImgLayer.isBaseLayer=false). Or take the image layers
as baselayers.

Yeah. FWIW, and in case we want to support IE < 8, I have a patch
implementing a "garbage bin element", see
<http://trac.openlayers.org/attachment/ticket/2170/patch-2170-A0.diff>.

Hello,
 
not that I'm aware. But images could be really large. 8000 x 4000 is no
problem. You have to wait a moment until the image is loaded, but afterwards
pan and zoom works lovely.

Arnd

Any ideas anyone?

I did wonder about projection issues: my data is EPSG:27700 but then so is
my map. And as I said, the static GML layer renders fine.

I have implemented the Tasmania demo [1] locally with my version of
Geoserver and OpenLayers.Layer.Vector() and that works OK.

?

Subject: [OpenLayers-Users] zooming a certain portion of the map
Message-ID: <1273866389486-5056929.post@n2.nabble.com>


Dear Friends,

I have a map which I display within a div of 600 * 600 pixels.This obviously
has an extent as defined in the map  file.

Now I want to zoom a certain rectangular portion of the map so that it
covers the entire map area i.e the entire div.
Now which functions do I use zoomto Extent() or zoomtoMaxExtent().
Which of these allow me to pass bounds?
1)Extent as defined in the map file and Bounds are the same thing?PLs
confirm.
2)Bound or extent is specified using a lonlat pair in the following pattern:

longitude 1 lattitude1 longitude2 lattitude2
Where longitude 1 lattitude1 is the co-ord of bottom left point,longitude2
lattitude2 is the co-ord of the top right point of the rectangle. 

Pls confirm whether my understanding in 1 & 2 are correct or not? 
Thanks for your attention.

I assume you are using version 1.1.0 with the WFS as 1.0 doesn't
support projections?

I've tried adding version: "1.1.0" to the protocol object, if that's what
you mean. The XML response is structured differently but it still does not
render.

If I'm understanding you correctly you need zoomToExtent [1], passing in an
OpenLayers.Bounds() object configured with your lon/lat pairs [2], e.g.

    map.zoomToExtent(new OpenLayers.Bounds(lattiude1, longitude1,
lattitude2, longitude2));

Figured it out. I suspected it would be something simple, and it was: I just
needed to remove the trailing slash from the featureNS value:

    var wfslayer = new OpenLayers.Layer.Vector("WFS", { 
        strategies: [new OpenLayers.Strategy.BBOX()], 
        protocol: new OpenLayers.Protocol.WFS({ 
            url: "http://d2.elgin.gov.uk/geoserver.2/wfs", 
            featureType: "NSG_STREET_PUBLIC", 
            featureNS: "http://www.elgin.gov.uk",                    // <--
removed trailing slash 
            featurePrefix: "e", 
            geometryName: "GEOM" 
        }) 
    }); 
    map.addLayer(wfslayer);

It would be nice if OL was a bit more forgiving!

Hi guys,
I need 2 pieces of information for a survey:

- and on the dev forum?

I couldn't find it on Nabble.

Thanks for any hint!

Subject: [OpenLayers-Users] custom cursor depends on activation order
Message-ID: <AANLkTinvrDO7Apt57ZIASkMQYhSposMTbMwZZMcAFFpZ@mail.gmail.com>

My map page has measure controls for path & polygon, and a DragPan
control, as well as various other controls. I have defined a custom
cursor for the DragPan as follows:

  .olControlDragPanActive {
    cursor: url('/mapserver/common/rwg/img/handRWG.cur'), auto;
  }

If the user activates DragPan before using a measure control, the
cursor for the measure control is the default pointer style. However,
if the user activates a measure control before doing a DragPan, the
cursor for the measure control is the one that I have defined above
for DragPanActive, which I do not want. To rephrase that: the measure
controls are using my custom DragPan cursor unless DragPan has been
previously activated and deactivated.

An example can be seen here:

Hello,

There are different approaches you can use to solve this.

1) As you are looking to represent on a map a concrete projection, is to have the coordinates (BBox in latlon, center in latlon and zoom for googlemaps) hardcoded in like a datamodel of your app.

So when you want to use them just map.setCenter(centerLatLon,zoomlvl,MapType.NORMAL_MAP_TYPE);

2) When working with different coordinate systems, like myself (epsg:23031), when you want to transform that coordinates to google ones you have to use one functionality, implemented by yourself.

googleLatLon = UTM2LatLon(myBBoxInUTM);
zoomLvl = getZoomForGoogleBBox(googleLatLon);

BTW it will not be stranger that someone implemented some webservice or so that given a name, like 'india' returns you the information needed to its representation, google can have that webservice itself, really I always work with 23031 so didn't searched for.

Subject: [OpenLayers-Users] Vector layer performance
Message-ID: <1274082121233-5064013.post@n2.nabble.com>


Hi list, 
I have a vector layer that is generated after a search, like this: the
search returns a list of numbers and those numbers are the id's from schools
in my country, so i do a query to the database and i get the coordinates and
features from those schools,
The layer is created properly but i have this problem: the search can return
a maximun of 15.000 schools but Openlayers home page recommends having only
around 2500 Coordinates

So this is mi cuestion: What's the alternative? I read about TEXT layers and
about GML layers but they keep all the data in the client side(is this
correct??), and that seems to be the problem
I also tried learning about php mapscript, by creating a dynamic layer by
changing the Data value on the mapfile but i do not know how to display that
layer with openlayers
Can i use Openlayers.layer.mapserver to do this?? 

I use mapserver and postgres.
Can someone point me to the right direction please !!
 
Thanks

Subject: [OpenLayers-Users] problem cluster attributs
Message-ID: <4BF112A1.9070109@gmail.com>

Hello.

Actually I'm in training in the INRA (agronomicaly institute) in France. 
I make a webmapping application about the genetically ressources.

I have a lot of points (sites) with different attributs, this attibuts 
is load in a grid panel. this panel display all site and attributs. The 
problem is that some points have the same location. For resolve this I 
think use the Cluster strategy of OpenLayers. Second problem: when I 
made a cluster with two (or more) points, this points disapear of my 
grid panel ad the cluster is create an empty line.

Have you a solution to keep my original data in the grid panel an, when 
i click on the cluster in the map, select the data point of the cluster 
in the grid panel?

If you have an other solution....


With my best regards (sorry for my english).

Fran?ois

Hello list,

we're having some trouble here with Ie8 and popup opacity issues. We use 
our own alpha-transparent background-image for popups. Works fine, 
except in Ie8, where the background is replaced by a grey color. Using 
the debugger, the filter property set by the 
OpenLayers.Popup.setOpacity() method seems to be the cause for this. 
Disabling it in the debugger makes the transparency work with the png.

I am not 100% sure what is causing this behavior, but with Ie8, a new 
method for setting opacity was introduced, see
http://msdn.microsoft.com/en-gb/library/ms530752.aspx
which is missing in the setOpacity() method. And there are some more 
issues with Ie and opacity, see the links mentioned below [1,2,3]


I don't know the reason for setting opacity (and others, border, 
bg-color) by javascript, but would'nt it be better to set them by css 
altogether?

Subject: [OpenLayers-Users] hovering-informations after 500 milliseconds
Message-ID: <20100517125227.128110@gmx.net>

Dear users,

I use a WFS to get informations to an object by hovering a feature like:

my_wfs_highlight = new OpenLayers.Control.GetFeature({
protocol: OpenLayers.Protocol.WFS.fromWMSLayer(my_layer),
hover: true,
clickTolerance: 15
});


...in generally this works finely, but:

If I move the mouse over some features I oftenly get failure messages in Firebug (e.g. "aborted" because the mouse doesn`t stop long enough over a feaure).

I wonder if its possible to send a request e.g. if the mouse is above a feature for 500 millisecondes or so, to avoid these error messages?
Or is it maybe possible to avoid error messages if a request is aborted?

Thank you very much, Kai

The GetFeature control uses a 250 ms delay. And AFAICT there's
currently no way to customize that, which is a shame.

It'd be great if you could create a ticket for that. Even greater
would a patch to GetFeature. A patch would probably just involve
having delay:250 in the prototype, and using this.delay when creating
the hover handler.

> Or is it maybe possible to avoid error messages if a request is aborted?

I don't recall seeing such errors on abort. What they look like exactly?

Cheers,

Subject: [OpenLayers-Users] Making vector layers.
Message-ID: <B633C48B3FED5142882256EE59B712F1016BAD20F7@datacenter-ex02.entrix.com>

I am having difficulty figuring out how to make a vector layer. At this point I have tried at least two different methods. One is importing the data as a KML file out of geoserver, the KML works fine in Google earth so I don't think it is an issue with the KML. The other is using WFS. In IE I am getting an unspecified error on line 634 of OpenLayers.js and firefox just does not display anything for that layer, it shows up in the layer switcher but does not show up on the map. The map_init function is called from body onload.

My actual goal is to fire onhover events from the points in the vector layer. The WMS layer is just the imagery. I am using the 2.9.1 version of openlayers.

var poles = null;
  var map = null;
  var drawControls;

function map_init(){

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

  map = new OpenLayers.Map({
    div: "map",
    maxExtent: new OpenLayers.Bounds(
      -82.134,27.544,-81.968,27.678
    ),
    allOverlays: true
  });

  var base = new OpenLayers.Layer.WMS(
    "Imagery",

Subject: [OpenLayers-Users] how to get layers in a layer
Message-ID: <4BF16E26.7040807@paqinteractive.com>


Hi all,

I've searched around on google for a while on this and haven't found an 
answer yet:
Can anyone show me an example of how to get the layers in a openlayers 
wms.layer?
Here's an example:

cities = new OpenLayers.Layer.WMS("US Cities", wms_path,
                     {layers: 'Public:US_Cities'}
);


I'm able to read items like the layer name (which would be "US Cities" 
in the above example, with:
layer.get("layer").name

but haven't had luck with getting the layers listed in the paramaters ( 
{ layers:   })
I want to know how to get the value 'Public:US_Cities'

Thanks,
Ryan

I downloaded a gpx file from here:

The file has the name and desc attributes.

You should change the way the file is loaded and the attributes you want
to display inside the popup.

Start with a simple working file and then add new features (not in OL

Use Firefox and firebug to watch the content of variables and attributes.

I'm seeing this problem in Safari. If the user uses the "zoom" feature of the
browser -- not the map's zoom feature -- polygons will get all out of whack.
If you don't know what I mean, It's the same button people press to up the
font size.

This thing still hanging around? Any have a fix? Should I file a bug report?

Ben.

Hi,

in Safari, you could enable the "Zoom text only" option in the View menu.

In my opinion, you should create a Safari/WebKit ticket for this, not an OpenLayers ticket. Page Zoom is supposed to zoom the whole page. Web applications don't even know that the page is zoomed, so it is unlikely that this can be fixed in OpenLayers.

If you create a Safari/WebKit ticket, it should read something like "When using page zoom, SVG content does not align with HTML and image content".

Regards,
Andreas.

Hello everyone,

I've been using the MinZoomLevel option on WFS layers to set the
minimum resolution beyond which a layer can be rendered (useful for
when there are lots of features).

Today I'm trying to the same with a WMS layer, but in that case the
MinZoomLevel option is ignored. Should it be working? If not how can i
be done for WMS layers?

I'm using OpenLayers 2.9. Thank you,

Hi,

use minResolution or minScale instead.

Luis,

  How about minScale or minResolution properties of the Layer object ?  
Here's an example using these properties, but the lines are commented 
and they are used in the map object.  Try one in one of your layer objects.

Alexandre

Hello all,

I am trying to display a map with openlayers but also provide
brightness/contrast sliders for the
user. I managed to implement a working demo for HTML5-Canvas with a static
image (without OpenLayers). 
My question is now if it is possible to use an OpenLayers-Canvas-Layer for
that as well.

Perhaps someone looked already into this and can give me a pointer?

Thank you,

Subject: [OpenLayers-Users] potential big IE performance enhancement- help!
Message-ID: <1274198295847-5070709.post@n2.nabble.com>


I think there is a potential to greatly improve the rendering performance  in
IE (cases of large# of points).

Take points for example.  In VML.js setStyle, every .style action seems to
trigger a browser reflow:
node.style.width="18px"; //1st reflow
node.style.height="18px"; //2nd reflow
node.style.top="10px"; //3rd reflow
node.style.left="10px"; //4th reflow

I am trying to do: 
node.style.cssText="width:18px;height:18px;top:10px;left:10px;"; //only 1
reflow!

The node.style.cssText only works the first time (when the point is
initially created and added).  If I zoom on the map, I see my .cssText
values changing (in IE Developer Tools) but the point always remains at the
original screen location :(

I am really pulling my hair out as to why we can't get node.style.cssText to
take effect after the initial draw.  Any ideas???  

PS: If I set node.style.cssText, remove the node (removeChild), and then do
this.vectorRoot.appendChild(node); the styling will be correct however the
remove&add obviously negate any styling performance gains.

Help!  Thank you!

Hi,

setting cssText is not the same as setting the style. But you could instead try to call

node.style.display = "none";

as first line of the setStyle method, and

node.style.display = "";

as last line of the setStyle method.

Let us know if this also boosts performance.

Good luck,
Andreas.

That actually seems a bit slower :(
2:59- to render my layer setting node.style.display="none"; then
node.style.display=""; 
2:42- the original way

I don't understand why setting node.style.cssText is different than
node.style.  Can you explain it briefly?  I ask because the simple example
below seems to work as I'd expect VML.js:setStyle to work.

Thanks again!

Because cssText is meant to set css on a CSS rule, not on a style. In IE, however, it works on styles (presumably accidently, and not very well). See the 2nd usage caveat on http://msdn.microsoft.com/en-us/library/ms533698(VS.85).aspx

You could try node.cssText instead of node.style.cssText. Wouldn't surprise me if that would do the trick.

Andreas.

Well, after many hours of struggling and the process of elimination I figured
it out .  I'll share my results for anyone else struggling like me .

Previously, I was using a getFullSRequestString with a OpenLayers.loadURL to
return an Ajax object that contained my GML information.  Then, I converted
the response into and XML format for parsing.

xmlFormat = new OpenLayers.Format.XML().read(response.responseText);

>From the XML, I needed to obtain some tag information.  I've placed a field
("feature") in my data that describes the title of the layer.  I used this
to identify which layer I'm working with.

featureType = xmlFormat.getElementsByTagName("feature")[0];  // This is the
part that did not work in IE but every other browser
lyrName = featureType.textContent;  // Provided me with layer name that was
stored in feature field

Since I'm rather new to DOM and XML parsing I had to dig a little deeper and
this is what I found. 

featureType = xmlFormat.getElementsByTagName("feature")[0].firstChild.data;

The above statement worked in all browsers: IE, Safari, Opera and Firefox.

I hope this helps.

Message-ID: <1274225184139-5072650.post@n2.nabble.com>


Hi all,

I have a function that is executed when a user hits a submit button in a
popup form (below). This saves changes both to the map feature and to the
database.

I have 2 problems.

One

My unselect isn't working - here and in other places in the code - but every
other function using my selectedFeature variable works fine.

selectControl.unselect(selectedFeature);

In some cases I want to destroy the feature and redraw it on another layer,
but so far have had no luck using the destroyFeatures function using any of
the various methods I've seen described online.

My variables are:
selectedFeature - the feature
origLayer - layer the feature is currently on
tgtLayer - layer the feature needs to be moved to

Any help anyone can provide would be greatly appreciated.


Thanks,

Nick.

Hi all,

Is there a way I could add additional parameters to event listeners? Please
refer to this example:

var control = new OpenLayers.Control.DrawFeature(
  someLayer, OpenLayers.Handler.Point, {
    featureAdded: someFunction
  });

...

function: someFunction(feature, param2) {
...
}

In the abovementioned example, how can I get the featureAdded event to
insert additional parameters to the "someFunction" method?

Thanks!!!

JavaScript and/or your favorite JS framework (JQuery, Ext JS) is your friend. Or have a look at GeoExt (http://geoext.org/) and the FeatureEditing ux (http://trac.geoext.org/wiki/ux/FeatureEditing).

Message-ID: <1274257239712-5073940.post@n2.nabble.com>


hallo,

i want to display on map some icons, written in a kml file. i do this with
the following statement:

  markers = new OpenLayers.Layer.GML("KML", "unit.kml",
               {format: OpenLayers.Format.KML,
                formatOptions: {
                  extractStyles: true,
                  extractAttributes: true,}
               });
   map.addLayer(markers);

this runs great, but now my problem: in the kml file is also the name of the
icon i am displaying:

 <Placemark>
         <name>Tractor1</name>
         <visibility>1</visibility>
         <open>0</open>
         <styleUrl>#SmallTractor</styleUrl>

            <coordinates>4.486325, 50.90313777777778</coordinates>
         </Point>
 </Placemark>

i want to open/show a label or popup by clicking on the icon in the map.
this label should show the name which is written in the kml file, in this
case the "Tractor1".

How can i realise that? Please Help

Thanks!

Hi All,

I would like to ask if there is a way to determine if the WFS
GetFeature request contains all the result features or there would be
more but the maxFeatures parameter clipped the result set. Well, my
OpenLayers application could know about the maxFeatures value, but if
the number of result features equals to maxFeatures, I'm still in
trouble. I've read the WFS specification, but no relevant tag is
presented there.

Sure, perform a GetFeature request with resultType hits and you'll know.

Hi Bart,

Yes, I know but that would be 2 requests each performing a possibly
long dastabase operation. And it would require extra processing on the
client side. Well, this would be required only for the equal case...

Now I know the solution. I specify a somewhat higher limit and if the
result count reaches the limit, I cancel the result set even if it
would be the equal case.

Hi,

i launch about 15 getCapabilities request before loading my map application.
i use GeoExt.data.WMSCapabilitiesStore and the proxy.cgi of openlayers in my url param to load my store.

item.layersStore = new GeoExt.data.WMSCapabilitiesStore({

url: '/cgi-bin/proxy.cgi?url=',

baseParams: { url : item.url + '?request=GetCapabilities&SERVICE=WMS&VERSION=1.1.1' + (item.namespace? '&NAMESPACE=' + item.namespace : '')}

});


it works well, but 15 requests make my app a bit slow to load. it's like other loading operations of the app (in particulary ajax ones) are interrupted until my 15 request haven't been all respond.

Is there a way to multithread all the request, or way that they take less ressources ?

Hi Ads,

It kinda depends what parameters you want in there. The "featureAdded"
handler is going to be a generic one, so it will have to get a lot of its
information about the feature and so-on at its own runtime. However, what
you probably want to do is use a closure:

var control = new OpenLayers.Control.DrawFeature(
 someLayer, OpenLayers.Handler.Point, {
   featureAdded: this.createFeatureAddedHandler(param1, param2)
 });

...

function: createFeatureAddedHandler(param1, param2) {
return function(feature) {
// In here you have access perpetually to the param1 and param2
// that were passed in when the handler was created.
}
}

If you'd like further information, the Wikipedia article has some good
examples, despite the obtuse introduction:
http://en.wikipedia.org/wiki/Closure_(computer_science)

Subject: [OpenLayers-Users] Help with Strategy.save and protocol.http
Message-ID: <4BF3F96B.3060209@metrico.lu>

Hello all,

I am currently (virtually ;-))fighting to understand how I can make an 
editable layer in OpenLayers. Especially the connection between the 
save-strategy and the protocol is difficult to understand. I already 
searched the docs and the mailing list, but was unable to find some kind 
of definition what exactly a strategy or a protocol is and for what kind 
of "behavoir" they are responsible.

I managed to create a working example, where I could edit/create/modify 
features and the changes were sent to my server but I really lack 
understanding how things work together ...

var points = new OpenLayers.Layer.Vector(
	'Viaah Points',
	{
		'protocol' : new OpenLayers.Protocol.HTTP(
				{
				'url' : '/my/layer.geojson',
				'format' : new OpenLayers.Format.GeoJSON()
				}
		),
		'strategies' : [
			new OpenLayers.Strategy.BBOX(),
			new OpenLayers.Strategy.Save({auto:true})
		]
	}
);

I added a standard editing toolbar, and with the auto:true save-strategy 
I could see the requests sent to the server in firebug.

 From what I have guessed so far: Is it true that the save-strategy uses 
the protocols methods for read/update/create/delete depending on the 
edit-actions taken by the user? And I presume it's somewhat hard-coded, 
that updates are done by a HTTP PUT, create by HTTP POST etc. ? In the

I am sure I have more questions, but these are the most basic ones

The save strategy just calls protocol.commit(). See
<http://trac.openlayers.org/browser/trunk/openlayers/lib/OpenLayers/Strategy/Save.js#L178>.

The protocol's commit method looks at the states of the features and
calls the appropriate method (update/create/delete). See
<http://trac.openlayers.org/browser/trunk/openlayers/lib/OpenLayers/Protocol/HTTP.js#L519>.

Yes.

No, after the response is received.

The code is a great information source to know about the internals of
OpenLayers :-)

There are others, but I used this example's basic form setup.

http://gis.ibbeck.de/ginfo/apps/OLExamples/OL26/examples/styles_unique_with_group.html
http://gis.ibbeck.de/ginfo/apps/OLExamples/OL26/examples/styles_unique_with_group.html 

For passing info to a database, AJAX can do that.

http://www.w3schools.com/ajax/default.asp
http://www.w3schools.com/ajax/default.asp 

The specific bits you really need are this (best defined globally):

		var xmlhttp;
		if (window.XMLHttpRequest)
			{// code for IE7+, Firefox, Chrome, Opera, Safari
			xmlhttp=new XMLHttpRequest();
			}
		else
			{// code for IE6, IE5
			xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
			}

and then in your function to save you need something like:

			var geom_x = feature.geometry.x;
			var geom_y = feature.geometry.y;

		
xmlhttp.open("GET","proc/proc_map_point_new.php?"map_num="+map_num+"&x="+geom_x+"&y="+geom_y,true);
			xmlhttp.send();

and if you want to return a confirmation of the edit changes:

			  if (xmlhttp.readyState==4 && xmlhttp.status==200)
				{
				document.getElementById("edit_msg_" + fid).innerHTML="Saved";
			  }

And you'll obviously need to alter the GET url to include any extra
attributes you want to save to the database from the form.

Be aware that when referencing popup forms, each popup form field needs to
be unique and the feature.id is a good way to do that, eg.

			  <input type="text" id="edit_title_' + feature.id + '" maxlength="20"
size = "25" value ="' + feature.attributes.title + '">

And referencing that value to send it to the database would be:

		function editPoint(fid){
			var ed_id = document.getElementById("disp_id_" + fid).value;

I'm far from an expert, but I know that it's possible to edit features on the
map and save those changes externally (eg to a database) without these
strategies or protocols. I write them directly to feature attributes and
send the data to a db with AJAX.

See the KML examples but basics are - use a SelectFeature control and 
assign events to featurehighlighted and featureunhighlighted.

My onfeaturehighlighted (following the examples closely), looks like 
below. Note the feature.attributes.name
which what you want.

         function onKmlFeatureSelect(event) {
              var feature = event.feature;
                 // Since KML is user-generated, do naive protection against
                 // Javascript.
                 var content
                 if (feature.style.balloonStyle)  {
                      // Use Style.js to replace balloonstyle variables 
with attribute values
                     content = 
OpenLayers.Style.createLiteral(feature.style.balloonStyle, feature);
                 } else if (!feature.attributes.description &&  
!feature.attributes.name) {
                     content = "<table border=\"1\">\n";
                     for (var i in feature.attributes){
                          content += "<tr><td>" + feature.attributes[i] 
+ "</td></tr>\n";
                     }
                     content += "</table>\n";
                 } else {
                     content = '<table><tr bgcolor="#9CBCE2"><th>' + 
feature.attributes.name + "</th></tr></table>" + 
feature.attributes.description;
                 }
                 if (content.search("<script") != -1) {
                     content = "Content contained Javascript! Escaped 
content below.<br />" + content.replace(/</g, "&lt;");
                 }
                 popup = new OpenLayers.Popup.FramedCloud("chicken",

                 feature.popup = popup;
                 map.addPopup(popup);
         }

Subject: [OpenLayers-Users] Using OpenLayers with Google,
	Vector and Geoscopio layers
Message-ID: <AANLkTim66zgFMTjA1rC2GZQZpSq0n0gGSPNgK_sqnBMF@mail.gmail.com>

Hi everyone,
I would use OpenLayers with Google maps, Vector layers and Geoscopio layers.
I think I've some trouble with projections.
Geoscopio maps are available with projections EPSG:4326 and EPSG:3003.
How can I set all parts to work together?

If I use "standard" projection for google

I'm using that code get from various examples, in that way the only layer
doesn't work properly is the "Tuscany Map":

...
var options = {
                projection: new OpenLayers.Projection("EPSG:900913"),
                displayProjection: new OpenLayers.Projection("EPSG:4326"),
                units: "m",
                maxResolution: 156543.0339,
                maxExtent: new OpenLayers.Bounds(-20037508.34, -20037508.34,
                                                 20037508.34, 20037508.34)
            };

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

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

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

            var wms = new OpenLayers.Layer.WMS("Tuscany Map",
                                   "
http://web.rete.toscana.it/sgrwms/com.rt.wms.RTmap?servicename=_rt_wms&version=1.1.1&SRS=EPSG:3003
",
                                   {
                                   projection: map.displayProjection,
                                   layers: 'idcomuni',
                                   transparent: 'true'
                                   });

             var layerGML = new OpenLayers.Layer.Vector("Layer Vector", {
                projection: map.displayProjection,
                strategies: [new OpenLayers.Strategy.Fixed()],
                protocol: new OpenLayers.Protocol.HTTP({
                    url: "markers.kml",
                    format: new OpenLayers.Format.KML({
                        extractStyles: true,
                        extractAttributes: true
                    })
                })

If it "just" calls protocol.commit(), what's the reason for having a 
save-strategy? Is it to have some kind of user - frontend to the 
protocols methods? If I don't use the save-strategies autosave feature, 
there's for me no difference wether I call protocol.commit() or 
strategy.save(). Or is there something more to using strategy.save() or 
strategies in general? Something like: "Don't use protocols directly, it 
is preferred to use them through strategies.", thus a design decision?

 From looking at the code ;-) I see that there is a projection check and 
an optional transformation to the remote projection, so that would be 
the "only" difference before protocol.commit(), right? I presume, the 
transformation is mostly there for the google projection (900913) to 
wgs84 transformation, or does OpenLayers have already some kind of proj 
support built in?

Well, obvious I am also far from being an expert, but I like to 
understand how things work together and from my standpoint I don't see 
the reason to wrap up my own communication protocol when I can use a 
built-in one, especially when I use GeoJSON as a transport format and I 
just need to specify that in my layer definition. This feels very 
snappy, it fits nicely together, simply using the protocol and strategy 
with my layer. No need to reenvent the wheel a second time ...


Well, thanks for the clarification so far. This should get me going with 
my project


Frank

I can appreciate that. I just thought it worth pointing out you can get by
without it in case no-one can provide a better answer.

I'm curious to see an answer to your question too. The save function I wrote
is quite short and simple - it's just feature.attributes.xxxx = "xxxx" etc.
and a couple of lines of standard AJAX. But if there is a built-in way to do
the same it would be interesting to see it.

I've only played with this a little bit myself, but Mika's suggestion in this

Look at the onCommit method in the strategy, it does some work.

To me there's no such principle.

onCommit does other things.

OpenLayers can be used with proj4js.

Hi, Firebug reports: this.div.appendChild is not a function    OpenLayers.js
(line 897) -> this.div.appendChild(this.element);

By using alerts I can see that this happens when the overviewmap control is
added to the map:

MAP.addControl(new OpenLayers.Control.OverviewMap({
    div: $('overviewmap'),
    size: new OpenLayers.Size(188, 97),
    minRectSize: 0
}));

The mouse position control has stopped working as well (I comment out the
overviewmap and get no errors).

This has worked perfectly for a long time, and I didn't change any libs
recently. Still using OL 2.8. What could cause this error?

I think using setLayer and then activating the strategy, at least that
what I did in my SOS Layer:

Using OL 2.9.1 did not solve it.

Subject: [OpenLayers-Users] renderintent not persistent
Message-ID: <4BF54827.6090100@metrico.lu>

Hi,

I have a modified ModifyFeature.handleKeypress function for deleting 
features from a layer. There I set the feature's state to deleted just 
as I do it with the renderIntent of the feature. Whenever I click into 
the map after deleting a feature, it appears back on the map because the 
renderIntent is somewhere set back to default. Unfortunately I can't 
find where or why.

My code so far (ModifyFeature.prototype.handleKeypress):

	...

	this.onModification(this.feature);
	this.layer.events.triggerEvent("featuremodified",
								   {feature: this.feature});
} else {
	if(confirm("Do you want to delete the selected feature?")){
		var feature = this.feature;
		if(feature.id == undefined) {
			this.layer.destroyFeatures([feature]);
		}
		feature.state = OpenLayers.State.DELETE;
		this.layer.drawFeature(feature, 'delete');
		feature.renderIntent = "delete";
	}
}

I could set the feature.style to 
OpenLayers.Feature.Vector.style["delete"] and this is persistent, but I 
wonder why the renderintent does not keep its state.

Message-ID: <1274366083654-5079946.post@n2.nabble.com>


Keywords: Openlayers, GeoExt, GeoServer, Browsers

Hi at all!

First of all..yep I know about similar problems in other threads and forums
but I dont find a solution for this problem.
I try to make a GeoExt.Popup with informations from WMSGetFeatureInfo in my
mapping-application. Here is the code for this popup:


// GeoExt Popup II
var featureInfo = new OpenLayers.Control.WMSGetFeatureInfo();
featureInfo.events.on({
    getfeatureinfo: function(e) {
        new GeoExt.Popup({
            	title: 'Feature Info',
            	width: 200,
            	height: 150,
            	autoScroll: true,
            	map: map,
            	lonlat: map.getLonLatFromPixel(e.xy),
            	html: e.text
        }).show();
    	setInfoToDiv(e.text);
    }
});
map.addControl(featureInfo);
featureInfo.activate();

// Method for testing Output in a DIV
function setInfoToDiv(text)
{
	document.getElementById("abfrage").innerHTML=text;	
}


For IE8 is everything fine. I get the FeatureInfo in the GeoExt.Popup and
the testing output in the DIV "abfrage". If I test it in Firefox3.5, I dont
get any output. Either the text in the GeoExt.Popup or the text in the DIV.
But I do get the Popup-Window (without any text). If I copy the Request
given me by Firebug in a new tab, I get the Response correctly.

What do I wrong? Any suggestions would help me.

THX
Martin

Your Tuscany Map url has SRS=EPSG:3003 which is not your map
displayProjection.  Change that to SRS=EPSG:4326.  Also, WMS layers are base
layers by default so you need to specify it is an overlay by writing
isBaseLayer: false in your options.

Try using featureName instead of typeName in your WFS Protocol parameters. 
Also, include featureNS even though it is technically optional.  Also, you
might want to explicitly declare your projection and displayProjection in
your map options as it may help the community analyze your issue.

I noticed the SRS value in the GetCapabilities return is messed up:

<SRS>EPSG:EPSG:4269</SRS> 

This might be a typo in your GeoServer layer.  Try changing that first.

In line with this, your WFS request has EPSG:4326 as SRS and your layer may
not provide EPSG:4326.  I can only see EPSG:4269 in your snippet of
GetCapabilities.

It was a jQuery $() problem. The noConflict method solved it.

<script type="text/javascript" src="jquery-1.4.2.min.js"></script>
<script type="text/javascript">$.noConflict();</script>

Thanks, yes I've done something like that lately, but the setLayer
is good to know about (I was naively setting strategy.layer directly)
For cluster I also had to handle the caching and initial clustering
myself.

My first thought was that you needed to specify 'layers' and 'layerstoquery'
parameters.  Maybe IE8 somehow manages to set the top/current layer.

To me this sounds more like a same origin issue. Internet Explorer treats the same domain with a different port as same origin:

http://localhost/
http://localhost:8080/

Other browsers don't.

First, make sure that you're adding your google layer to map.  In one of your
examples, you only added the wms layer.

Second, since google maps are EPSG:900913, you'll need to pass it meters
instead of a lon,lat.  Set up a point or bounds you know (lon,lat) and then
transform that point/bounds to the google projection.

// I saw a reference to this lat,lon coordinate: 63.259591,-144.667969

var GEOGRAPHIC_PROJECTION = new OpenLayers.Projection("EPSG:4326"); // stnd
LAT,LON via WGS84 datum
var MERCATOR_PROJECTION =   new OpenLayers.Projection("EPSG:900913"); //
'900913' == 'GOOGLE' projection
var IndiaCenterPointGeographic = new
OpenLayers.LonLat(-144.667969,63.259591); // lon,lat
var IndiaCenterPointMercator =
IndiaCenterPointGeographic.transform(GEOGRAPHIC_PROJECTION,MERCATOR_PROJECTION);
var startZoomLevel = 5;
//....
//set up map and layers...
//....
map.setCenter(IndiaCenterPointMercator,startZoomLevel);

I've tried also in that way (and in many others), but the Tuscany map is not
properly shown (it's very small and moved respect the others).

Subject: [OpenLayers-Users] loading panel question
Message-ID: <003101caf8bb$ea9a6440$bfcf2cc0$@green@ibstv.co.uk>

Hi list

 

I have been trying to make the loading panel work, as per
http://trac.openlayers.org/wiki/Addins/LoadingPanel but can't seem to make
it work.

 

I am using OL 2.8  (also tried 2.9 - same problem) which is referenced in my
code as:  <script src="../OpenLayers-2.8/lib/OpenLayers.js"></script>.

 

I downloaded LoadingPanel.js and put it in the directory
OpenLayers-2.8/lib/OpenLayers/Control.  Then when creating a map I have: 

 

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

 var loadingpanel = new OpenLayers.Control.LoadingPanel()

                map.addControl(loadingpanel);

 

This throws an error in Firefox:  "OpenLayers.Control.LoadingPanel is not a
constructor"

 

The loading panel instructions talk about creating a single file build which
I have not done - is this my problem, or should I be able to make this work
with the OL 2.8  development libraries?

 

 

Chris

Hi Chris,

if you do it this way, you need to add an entry to your OpenLayers.js:

   if(!singleFile) {
        var jsfiles = new Array(
            ..
            "OpenLayers/Control.js",
            "OpenLayers/Control/LoadingPanel.js",
           ..

Best regards,
Bart

Subject: [OpenLayers-Users] IE7 and Firefox draws icons to different places
Message-ID: <1274432498271-5083376.post@n2.nabble.com>


Hi,
 I have some icons in my map ponting to interesting places. Points are
vector features and icon path is in styleparameters of the feature. There is
also graphicWidth and graphicHeight values but no graphicXOffset and no
graphicYOffset in styleparameters. 

Left picture is from Firefox and right one from IE7. Popup points to the
coordinate point of the feature correctly and Firefox draws the icon to
correct place. In IE7 X axis is correct but Y is in different place, the
offset doesn't depend on zoomlevel, it is always the same (In pixels). Am I
doing something wrong or is this known problem with IE. Should I check which
browser is in use and put some offset to style parameters in IE7?

Br,

ahlah

Hi Bart

Thanks for the help. I found  " if(!singleFile) {var jsfiles = new
Array(....." in OpenLayers.js and added 

  "OpenLayers/Control.js", "OpenLayers/Control/LoadingPanel.js",


at the end of the (very long) list of controls. Unfortunately I still get
the same result: "OpenLayers.Control.LoadingPanel is not a constructor" 


Did I do it wrong?


Chris

Message-ID: <201005211208.04773.ale.pas@tiscali.it>

Hello,

I've discovered a strange behaviour (bug?) with FF and select control.

Basically, it happens when you already have an active  control 
Control.SelectFeature attached to a layer and you add a new layer with its own 
Control.SelectFeature, on FF the control attached to the first layer will cease 
to react to click events.

See a live example here (test it on FF and Chrome):

http://www.parconord.milano.it/ol_ko.html

I don't need a workaround (I've already found one), but I would be happy to 
understand why it happens.


Tested on:
FF 3.6.3 Linux
Chromium
5.0.389.0 (45661) Ubuntu

Hello,

Same behavior here.
But it works when the 2 vector layers are passed to the SelectFeature control:
  new OpenLayers.Control.SelectFeature([vectorLayer, vectorLayer2], {
clickout: true, hover: false });

Is that what you used ?

Hi,

Yes, it works if you pass both layers simultanously to the control init, but 
in my project the layers were added dynamically so that was not the ideal 
solution. 

The workaround is to scan existing layers and pass them all every time you add 
a new control.

But the question remains: why does it work fine on Chrome and fail on FF ?

Is this a bug in ol, in FF or is it just Chrome that has an odd behaviour ?

Hi Chris,

only add the line wrt to the LoadingPanel.js, not an extra line for
Control.js.

Install Firebug in Firefox and see if the file actually gets loaded in the
scripts tab.

Bart

I changed the entry so it only adds "OpenLayers/Control/LoadingPanel.js",
but still the same result. The Firefox script tab shows a list of controls
but LoadingPanel.js is not there. Could it be a problem with the
LoadingPanel.js file?

Subject: [OpenLayers-Users] Large Dataset
Message-ID: <1274469144963-5085920.post@n2.nabble.com>


Hi, 

I need an advice. 
I have a dataset of about 1.5Mil locations that i need to display within
OpenLayers. 


Also currently i'm displaying results as a WMS layer at the moment (there is
geoserver running in the background). There are number of filters that i'm
applying to minimize number of returned results.
Still i see anywhere from 5 - 15 sec delay before my layer is rendered, I
assume mostly because of the searching the dataset. This is a temporary
workaround since in few weeks the 1.5 Mil number will be more like 5-10 Mil. 

Is there a better way to search / display  such a huge dataset ? 
Maybe OpenLayers can handle this amount of info without geoserver help. 

Thanks,
-y

Yurka,

What format are you storing your data in?  Shapefile... PostGIS?  I doubt
there is a much more efficient way of handling that size dataset than your
current GeoServer/WMS method.  You may be able to optimize your current
setup by utilizing PostGIS Views rather than WMS Filters.  You may also want
to play around with setting scale thresholds for your image rendering- and
you could try using a single tile WMS layer.

Best of luck!

BRYAN

Well it may sound weird but the data is stored  in MYSql ... 
Transfer to PostGIS was my next step to try. 

If i understood you correctly,
in my case its impossible to use views since some of the input comes from
user. 


I will try to use singe tiled WMS see if its better. 
Thanks for quick response,

Pretty standard question, but do you have any indexes on the data?

Yes,
each field i filter by is indexed, 
Also i couldn't create GIS-Index on MySQL due to non-null constrain 
but I should be able to once i remove all nulls.

The nabble archive search is down so there may have been prior
discussion on this.

Are there any plans to support (or is it possible now) to do
'infinite' panning around the dateline w/OL?

I.e. how google and bing's map apis let you keep panning east/west indefinitely.

thanks,

Have you tried the wrapDateLine option?

Hi,

this could be a VML renderer bug. But to investigate, I'd ask you to provide a minimal example showing the issue.

Thanks,
Andreas.

I think the proper way to solve this would be a setLayers method for the SelectFeature control.

I have been trying for a long time(since february 2010) to use GetFeatureInfo

get the attribute name "[NAME]" (as it appears on the html body template
file) AND not the atrribute values. Please help.Here is the openlayers file

Oh, and I was the reviewer. Great!

Well in that case, the solution to the OP's problem is to reconfigure the control with the new set of layers after adding/removing layers, instead of creating a new control with a new layer.

Andreas.

Thank you all for the suggestions,

The suggested workaround works on both FF and Chrome, but I'm still confused: 
what if I need two different controls instances attached to the the two layers 
?

Suppose I want the Control.SelectFeature attached to the first layer to open a 
popup and the Control.SelectFeature attached to the second layer to update a 
div somewhere in the page.

Does Control.SelectFeature really needs to be a singleton ?

Additionaly: why on Chrome I can have two different controls attached to my two 
layers and on FF I can't ?


This doesn't work on FF (lower left point click is not active) but works on 
Chrome:
http://www.parconord.milano.it/ol_ko.html

Should I file a bug report ?

You can check for the layer that a feature was selected on in the event handler and perform different actions based on that. Why would you need a second control for that?

> Does Control.SelectFeature really needs to be a singleton ?

No, you can have as many SelectFeature controls as you want. But the way it works is that it needs to put the layers to select from at the top of the layer stack, and this is why you should just have one SelectFeature contorl *activated* at a time.

> Additionaly: why on Chrome I can have two different controls attached to my two

This must have to do with the way events are handled on SVG elements. But I cannot tell you exactly why.

No, because having two active SelectFeature controls is not supported.

If you want smarter feature selection, have a look at http://trac.openlayers.org/changeset/9739 - this could become the way we handle feature selection in the future.

Andreas.

Subject: [OpenLayers-Users] display different popup for different layer
Message-ID: <AANLkTin1u8oLiXt1bl00GHXg_UfdiV-6QyTGkvPOa16d@mail.gmail.com>

Hi all,
in my project I've 2 layers (layer1, layer2) with different attributes.
Layer 1 is in gml format, layer2 is a txt file
When I click on the layer1, I open a popup with this code:

function onPopupClose(evt) {selectControl.unselect(feature);}

//al click su un elemento, creo e visualizzo al popup
function onFeatureSelect(event) {
       feature = event.feature;
       popup = new OpenLayers.Popup.FramedCloud("chicken",
                  feature.geometry.getBounds().getCenterLonLat(),
                  null,
                  "<div><b>Nome:</b> <a href=\"scheda_comune.php?comune=" +
feature.attributes.NOME + "\" target=\"eastFrame\"
onClick=\"outerLayout.open('east')\">" + feature.attributes.NOME
+"</a></div>",
                  null, true, onPopupClose);
       feature.popup = popup;
       map.addPopup(popup);
      }

function onFeatureUnselect(event) {
        feature = event.feature;
       if (feature.popup){
           map.removePopup(feature.popup);
           feature.popup.destroy();
           feature.popup = null;
      }
     }
....

selectControl = new OpenLayers.Control.SelectFeature(layer1);
   //{onSelect: onFeatureSelect, onUnselect: onFeatureUnselect});
    layer1.events.on({
                "featureselected": onFeatureSelect,
                "featureunselected": onFeatureUnselect
            });


Now I'd like to display the same kind of popup for the layer2 but I don't
know what is the correct code to write!!!


thanks

Message-ID: <1274734301103-5095731.post@n2.nabble.com>


Hi!

It has been a while since I got any problems with OL but this time has
unfortunately come...
Actually I am just looking for some solution for my task...
I got some images that shows the city of New York with the streets hotels
and some other objects. All this data are stored as jpg files. I have images
of N.Y. in different scales e.g. 1:1000, 1:5000 and so on... So for example
I got 9 images of N.Y in scale 1:1000, 9 images in scale 1:2000 etc... I
have also got the center point of each picture. My task is to use them all
in openlayers. But I have to:
- presents not one picture on map but many pictures in some order. I mean
like this:

1.jpg 2.jpg 3.jpg
4.jpg 5.jpg 6.jpg
7.jpg 8.jpg 9.jpg

I have to glue them together using openlayers to preset the hole map of N.Y.
- I have to change all the images when someone changes the scale (zoom) 

I was thinking about using the Image layer, but as far I know, one Image
layer does not allow to present many pictures... in url you define just the
string to url, and not the e.g table of images...

I know it is not standard question but maybe someone has any ideas... or
thoughts on this... 

Any help would be appreciated

Regards
Poul

Hi,
is it possible that the clone() method of OL.Layer.Vector clones the 
features but forgets to set the layer attribute of each feature to the 
cloned layer?
I had the problem, that I couldn't modify the features in the new layer 
until I wrote the following code after cloning:
for (var t = 0; t < newLayer.features.length; t++) {
     newLayer.features[t].layer = newLayer;
}
It's a bug or a feature?

Hi list,

when serializing features with null values on attributes on IE8,
then there is a exception  in XML.createTextNode.
Line 247  "node = this.xmldom.createTextNode(text);" fails,
as text is a null-Object.
Placing             "if (text==null) text='';" before works fine.

Any better suggestions?
FF works fine!

Hi,

I think that passing both layers to the select control should work:

selectControl = new OpenLayers.Control.SelectFeature([layer1, layer2]);
selectControl.events.register("featureselected", map, onFeatureSelect);
selectControl.events.register("featureunselected", map, onFeatureUnselect);
map.addControl(selectControl);
selectControl.activate();

Hello everyone,

Please check the code below. This is a very simple map with an event
listener that shows the coordinates when you click on it. It works on every
know web browser in the world, Firefox, Opera, Chrome, except for ... yes
you guessed it, Internet Explorer!

Is there any work around for this? Is it worth to dedicate time to this? Is
OpenLayers supposed to work with IE?

Thank you,

Hi,

I use
map = new OpenLayers.Map(map_div);
...
map.events.register("click", map, showCoords);

where showCoords the function for display is. Alternatively see 
http://dev.openlayers.org/releases/OpenLayers-2.9.1/examples/events.html 
for an alternate example

Subject: [OpenLayers-Users] Format.geojson.write - missing crs with
	featurecollection
Message-ID: <4BFBB686.9070502@metrico.lu>

Hi,

I'm using Format.GeoJSON for talking with my server. When creating new 
Features and sending them to my server I saw that OL sends the new 
features as a featurecollection object. But there is no crs attached. 
Looking at the code, the crs is only attached to instances of 
OL.Features.Vector. Featurecollections are typeof array and there's no 
crs attachment done in the code. I prepared a small snipped to fix this:

     write: function(obj, pretty) {
         console.info(obj)
         var geojson = {
             "type": null
         };
         if(obj instanceof Array) {
             geojson.type = "FeatureCollection";
             var numFeatures = obj.length;
             geojson.features = new Array(numFeatures);

++            if(obj[0].layer && obj[0].layer.projection) {
++               geojson.crs = this.createCRSObject(obj[0]);
++            }

             for(var i=0; i<numFeatures; ++i) {
                 var element = obj[i];
                 console.log(element)
                 if(!element instanceof OpenLayers.Feature.Vector) {
                     var msg = "FeatureCollection only supports 
collections " +
                               "of features: " + element;
                     throw msg;
                 }
                 geojson.features[i] = this.extract.feature.apply(
                     this, [element]
                 );
             }
         } else if (obj.CLASS_NAME.indexOf("OpenLayers.Geometry") == 0) {
             geojson = this.extract.geometry.apply(this, [obj]);
         } else if (obj instanceof OpenLayers.Feature.Vector) {
             geojson = this.extract.feature.apply(this, [obj]);
             if(obj.layer && obj.layer.projection) {
                 geojson.crs = this.createCRSObject(obj);
             }
         }
         return OpenLayers.Format.JSON.prototype.write.apply(this,
                                                             [geojson, 
pretty]);
     }

I don't know if it is intentionally left out, but I thougth I let 
someone know ...

Hi Frank,

Thank you for your help, but the problem isn't registering the listener, but
the argument IE is passing to it. The object with which the showCoords
function is invoked seems to null, so the .xy property generates an error.

Thanks,

Lu?s

Hi,

well obviously you can't pass any arguments to an event function (in 
IE). The function only has access to window.event. You can do

function coords(event) {
		var xy = event.object.getLonLatFromViewPortPx(event.xy);
		var x = xy.lon;
		var y = xy.lat;
		...
}

if you enable the console in IE8, you can do inside the event function: 
console.log(event) to see what you get

Robert,

Welcome to OpenLayers!  You have several options for getting your GIS data
into OL.  The size of your shapefile and the number of features you are
managing will most likely drive what format will work best in your
situation.  If you are working with tens or even hundreds of points, you may
be able to get away with converting the shapefile to a KML or text file and
loading it directly in OL.  If you've got several hundred or thousands of
points, you will probably want to involve some server side processes for
managing what gets thrown at the browser.  You could easily use a shapefile
data store in GeoServer to render the points as a WMS layer.  The benefit of
this approach is that your GIS users will also be able to tap into the WMS
feed within their GIS software for real-time access to your data.  If
GeoServer is not an option, you could load the shapefile data into a PostGIS
or MySQL database and use PHP to generate only the relevant bits of JSON or
KML on the fly.

Let me know if you need any help or further clarification and best of luck!

BRYAN

Hi,

I made a simple example with hardcoded values and both browsers works fine,
icon is in same correct place. So it seems that  problem isn't in renderer.
But there is some difference in behaviour between Firefox and IE because the
use case is same, data in database is same and javascript code is same. I'll
compare the behaviour with debugger, maybe I can find out something.....

Br,

Thank you Frank, that did it, works both with Firefox and IE.

Note though that the listener has to be registered the way you indicated,
not how I had tried initially. Full code below.

Thanks,

Hi,

It's an issue with MapServer. If the returned html shows only "[NAME]" as in
the template, then it means, that MapServer couldn't resolve the tag.
Perhaps you have no column NAME in your data or it's an issue with upper and
lowercase.

Try

'wms_feature_info_mime_type' 'text/plain'
'wms_include_items'  'all'

To get the result with all attributes, that are availible.

Subject: [OpenLayers-Users] Converting distance to map units?
Message-ID: <BAY109-W334F940CF88E1FE67182891E80@phx.gbl>


I am trying to create a circle with fixed radius programatically and am using OpenLayers.Geometry.Polygon.createRegularPolygon(center, radius, sides, angle) to do that.  

I have trouble converting my distance, say 800 feet, to the correct radius value in map units.  This is what I do:

 

var inches = OpenLayers.INCHES_PER_UNIT;

radius = radius * inches["ft"] / inches[map.getUnits()];

 

The circle drawn has smaller radius than what I wanted.  What's the right way of converting real distance to map units?  And by 'map units', does it mean the value returned by map.getUnits()?

 

Thanks for any help.

 

Cynthia

Hi

As a workaround you could try with a point vectorlayer and externalGraphic.
With small images it works. 

Problem is, when the insert point is outside the viewport, then the
externalGraphic will not displayed.

Example with nine images

Betreff: [OpenLayers-Users] Layer from raster images...


Hi!

It has been a while since I got any problems with OL but this time has
unfortunately come...
Actually I am just looking for some solution for my task...
I got some images that shows the city of New York with the streets hotels
and some other objects. All this data are stored as jpg files. I have images
of N.Y. in different scales e.g. 1:1000, 1:5000 and so on... So for example
I got 9 images of N.Y in scale 1:1000, 9 images in scale 1:2000 etc... I
have also got the center point of each picture. My task is to use them all
in openlayers. But I have to:
- presents not one picture on map but many pictures in some order. I mean
like this:

1.jpg 2.jpg 3.jpg
4.jpg 5.jpg 6.jpg
7.jpg 8.jpg 9.jpg

I have to glue them together using openlayers to preset the hole map of N.Y.
- I have to change all the images when someone changes the scale (zoom) 

I was thinking about using the Image layer, but as far I know, one Image
layer does not allow to present many pictures... in url you define just the
string to url, and not the e.g table of images...

I know it is not standard question but maybe someone has any ideas... or
thoughts on this... 

Any help would be appreciated

Regards
Poul

If I understand what you want correctly, this is shown in the examples.  

 

I used it in my project (demo here):  http://marjie.info/map/

 

In the javascript, after initialiazing your map:

 

map.addControl(new OpenLayers.Control.LayerSwitcher(

                { 'div': OpenLayers.Util.getElement('right') }));

 

In the html:

 

<div id="right" class="olControlLayerSwitcher"></div>

 

You will probably want to override the ControlLayerSwitcher style in your CSS as well.

I'm embarking on an ambitious project with ArcGIS Server and would like 
to use OpenLayers for the front-end. I found some info 
(http://www.mkgeomatics.com/apps/REST_Dev/) about adding identify & 
geoprocessing support but the links to august's sandbox are dead and the 
work has been removed from trac.openlayers.org. Is this a dead project 
or has it graduated to something more official? Is there much going on 
these days with OL + AGS integration?

1/ I notice V2 of the google Map API is now deprecated. Is there a 
development to move openlayers to V3? (looks like some good reasons to 
do so).

2/ Anyone know if there is a way to get at unminified google maps api? 
One the issues I have is where the checkresize() method is called. In a 
GOOD working version, the checkresize() changes values of mapobject 
properties (notable Yb which is clearly bounds) whereas a non-working 
version (when using a treepanel) doesnt cause changes. I am trying hard 
to find out what controls what checkresize() does so I can modify
it in openlayers before that call.

The v3 support of OpenLayers is ready (http://dev.openlayers.org/sandbox/ahocevar/gmaps-v3/examples/google-v3.html), but we are blocked by http://code.google.com/p/gmaps-api-issues/issues/detail?id=2346 to make panning work correctly. Please star this issue to raise its importance to the GMaps development team.

I don't think so. But you would have to ask the GMaps development team at Google.

Hi,
I've two overlays, one is a Vector layers of markers built from a kml file,
the other is a GML geometric layer from an xml file.
I've added a SelectFeature for each layer, but if I add first layer1 then
layer2
only selectFeature for layer2 work. On otherwise if I add layer2 then layer1
only
selectFeature for layer1 work, there is a way to make working both layers?
Here the code:

var layer1 = new OpenLayers.Layer.Vector("Segnalazioni", {
    'displayInLayerSwitcher':false,
    styleMap: new OpenLayers.StyleMap(style),
    projection: map.displayProjection,
    strategies: [new OpenLayers.Strategy.Fixed()],

        })

});

var  layer2 = new OpenLayers.Layer.GML(
    "GML",
    "file.xml",
    {
        projection: map.displayProjection,
        styleMap: myStyleMap,
        'displayInLayerSwitcher':false,
        'isBaseLayer':false
    }
);




selectControl = new OpenLayers.Control.SelectFeature(
    layer2,
    {
        clickout: true, toggle: true,
        multiple: false, hover: true
    }
);

layer2.events.on(
    {
        "featureselected": function(e) {
            alert("Selected.");
        },
        "featureunselected": function(e) {
            alert("Unselected.");
        }
    }
);

map.addControl(selectControl);
selectControl.activate();

select = new OpenLayers.Control.SelectFeature(layer1);
layer1.events.on(
    {

Hi everybody,

I cannot find a complete manual about using openlayers with arcims.
I need to use openlayers with an existing arcIMS installation but I don't
know who made it and what are the settings and components needed for using
it with openlayers (I mean, proxy.cgi, servlet engine and stuff like that).
Anyone can help me?

Thank you in advance

Hi,

I finally found bug from my code: graphicHeight was string instead of of
integer and that caused error in calculating y offset in IE. -13.5 + "27" is
-13.527 instead of 13.5 :(

SVG renderer in Firefox calculates offset differently than VML renderer in
IE, luckily the string didn't cause any harm in Firefox.

Br,

Thanks for the answer,
but that solution in my case works only with Chrome Browser.
In Chrome also works the two-select solution.
With any other browser:
two-select works only the upper layer
one-select doesn't work any layer

Probably a dumb thought but why not using directly:

node.style="width:18px;height:18px;top:10px;left:10px;";

Because cssText is meant to set css on a CSS rule, not on a style. In
IE, however, it works on styles (presumably accidently, and not very
well). See the 2nd usage caveat on
http://msdn.microsoft.com/en-us/library/ms533698(VS.85).aspx

You could try node.cssText instead of node.style.cssText. Wouldn't
surprise me if that would do the trick.

Andreas.

I've tried your suggestion with OL 2.9 now, but there is no change. Any idea why?

My wfs-server can deliver GML 2.1.2, GML 3.0, GML 3.1.1 and GML 3.2. What does OL need?

Hi,

A similar problem has been discussed just a few days ago, please read the 
thread:

Thanks for the answers!

@cd: My version is correctly. It makes a request to the WMS of the
GeoServer. The params are optional.

@Andreas: I've tried the second link and after I paste the code for the
VitualHost-section, the Apache won't start again. The errormessage is "The
requested operation has failed!". If I comment the VirtualHost-section,
apache starts again. After that, I wanted to try the second link. I noticed
that there is no path like /usr/lib/cgi-bin/ in my Apache-installation. So
do you have some further informations for me?

Here is the VitualHost-section in my httpd.conf

<VirtualHost>
ProxyRequest Off
# Remember to turn the next line off if you are proxying to a
NameVirtualHost
ProxyPreserveHost On
<Proxy>
	Order deny,allow
	Allow from all
</Proxy>
ProxyPass /geoserver http://localhost:8090/geoserver
ProxyPassReverse /geoserver http://localhost:8090/geoserver

Hi,

for Apache proxy to work you need the mod_proxy module.

More info can be found in the Apache documentation.

Regards,
Andreas.

You mean these two modules?


LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so


I have these modules and took the comments away.

Hello, 

I was wondering if it's possible to use an image (png,gif,whatever) to use it like a fill pattern, to fill a polygon?
 
Thanks.

Un saludo,

Yes, exactly these two. You need to have them installed, not just uncommented.

The snippet in the link I had sent you means to paste the proxy code (everything between the # ... lines) into your existing VirtualHost section, not to create a new VirtualHost section.

Please refer to the Apache documentation for more help.

Andreas.

Ok my fault. Look again at the VirtualHosts-section. There is a spelling
error. 

ProxyRequest Off is wrong. Changed it to ProxyRequests Off and now the
Apache runs. Thanks again and sorry about my mistake.
My problem is still exist. The Popup is empty and the request on new tab
returns a result.

Have you also changed the url of your wms from http://your.url/path/wms to /path/wms ?

If so, then we need more information from you:

* the url you access your page with
* the url of your wms layer
* the response of your GetFeatureInfo request

Regards,
Andreas.

One question, yet. Why do I have to use a Proxy for the Popups? Is this a bug
of GeoServer or OpenLayers?

It looks like you can style a vector layer using SLD- 
http://openlayers.org/dev/examples/sld.html
http://openlayers.org/dev/examples/sld.html 

Have a look at the recently updated 
http://docs.geoserver.org/stable/en/user/styling/sld-cookbook/index.html SLD
Cookbook  for examples.  The link for polygons with a graphic fill is here: 
http://docs.geoserver.org/stable/en/user/styling/sld-cookbook/polygons.html#graphic-fill
http://docs.geoserver.org/stable/en/user/styling/sld-cookbook/polygons.html#graphic-fill

I have a requirement for the OpenLayers LayerSwitcher to have icons beside the
overlay layers. Is this possible?

Mak,

You can accomplish this very easily by including some html in your layer
constructor code...

var layer = new OpenLayers.Layer.WMS( " http://www.myhost.com/myimage.png
&nbsp;OpenLayers WMS",
"http://labs.metacarta.com/wms/vmap0", {layers: 'basic'} );
map.addLayer(layer);

Hi,

have a look at
http://openlayers.org/dev/examples/arcgis93rest.html
and
http://dev.openlayers.org/releases/OpenLayers-2.9.1/doc/apidocs/files/OpenLayers/Layer/ArcGIS93Rest-js.html

This is all officially in the 2.9.1 release of OpenLayers.

Regards,
Andreas.

If your AGS Service has WMS support activated, you may be able to go that
route...  So for the dev example you would use: 
http://sampleserver1.arcgisonline.com/arcgis/services/Specialty/ESRI_StateCityHighway_USA/MapServer/WMSServer?request=GetCapabilities&service=WMS
http://sampleserver1.arcgisonline.com/arcgis/services/Specialty/ESRI_StateCityHighway_USA/MapServer/WMSServer?request=GetCapabilities&service=WMS
.  I guess it really depends upon how ambitious your project is and what
sort of AGS functionality you are looking to expose to OL.

Message-ID: <CB506E813C77E9498F043F1F951BB2768DFF6F7738@optimus.ms.a2end.com>

Hello,

I want to dynamically set a strokeColor based on feature.styler.color rather that feature.attribute.color.

I am using this code:

var context = function(feature) {
                feature.stylers ? ret = feature.stylers : ret = feature.attributes;
                ret ? null : ret = feature;
                return ret;
}

var defaultStyle = new OpenLayers.Style(OpenLayers.Util.applyDefaults({ strokeColor: "${color}", strokeWidth: 3 }
        , OpenLayers.Feature.Vector.style["default"]), {context: context});

I have also tried this:

var defaultStyle = new OpenLayers.Style(OpenLayers.Util.applyDefaults({ strokeColor: "${color}", strokeWidth: 3 }
        , OpenLayers.Feature.Vector.style["default"]), {context: {styler: null}}) ;

But neither seem to work! I am particularly confused as the top example works for OpenLayers.Rule context manipulation.

Any hints?

Mmhh, I've tried but it's doesn't work, I think because the layer's
attributes are different and I cannot define the same popup content.
I've risolved writing a second function:
function onFeatureSelect(event) {
       feature = event.feature;
       popup = new OpenLayers.Popup.FramedCloud("chicken",
                  feature.geometry.getBounds().getCenterLonLat(),
                  null,
                  "<div><b>Nome:</b> <a href=\"scheda_comune.php?comune=" +
feature.attributes.NOME + "\" target=\"eastFrame\"
onClick=\"outerLayout.open('east')\">" + feature.attributes.NOME
+"</a></div>",
                  null, true, onPopupClose);
       feature.popup = popup;
       map.addPopup(popup);
      }

and

function onFeatureSelect2(event) {
       feature = event.feature;
       popup = new OpenLayers.Popup.FramedCloud("chicken",
                  feature.geometry.getBounds().getCenterLonLat(),
                  null,
                  "<h2>" + feature.attributes.title + "</h2>" +
feature.attributes.description,
                  null, true, onPopupClose);
       feature.popup = popup;
       map.addPopup(popup);
      }

...
...
toscana.events.on({
                "featureselected": onFeatureSelect,
                "featureunselected": onFeatureUnselect
            });
   poi.events.on({
       "featureselected": onFeatureSelect2,
       "featureunselected": onFeatureUnselect2
   });

...maybe I could write better code but ... it works!!!

thanks

Hi folks!!

I think Andreas has pointed the right way. I forgot to mention or maybe I didn't explain it clearly enough, but what I was asking about features of a OpenLayers.Vector layer an it's associated style without using SLD, just using OL style.

Thanks.

Hi,

you are using the context in an incorrect way. Try something like

var context = {
    color: function(feature) {
        return feature.stylers.color;
    }
};

If you have your color in feature.attributes, you don't need a context at all.

Regards,
Andreas.

Subject: [OpenLayers-Users] Vector Feature Popup without select?
Message-ID: <1274956116051-5107915.post@n2.nabble.com>


I am researching how to add an onClick event to a point feature on a vector
layer to generate a pop-up or add it to selection based on a toolbar switch.

As far as I can tell, the only method of launching pop-ups on vectors is to
use feature selected? What if I want to select the feature (add it to a
selection layer) without launching a pop-up.

Markers is the old approach bit it seems straightforward to add an onClick
handler to a marker. Can't say the same for a vector point layer or am I
missing something?

Appreciate any guidance.

See http://pgrouting.postlbs.org/

This works on a server but can be integrated with OpenLayers to display 
the results.

OL can not do the routing in the javascript client.

Message-ID: <AANLkTik_AnjhevsQIXXO-Vs4zPsYgvrb1KcULgcl3thd@mail.gmail.com>

Hi List,

If you  want to click something else than the Control to toggle the
layerswitcher you need  an extra function to check the state of the Control
by looking at the minimizedDiv or maximizedDiv propery. I never worried
about the logic of the terms.

If the maximizeDiv display =="none" the switchercontrol is in the maximized
state so it seems

so:

  OpenLayers.Control.LayerSwitcher.prototype.isShowControls  = function  ()
{

        return(this.maximizeDiv.style.display=="none") ;
  }

usage:
        if(layerSwitcher.isShowControls())
            layerSwitcher.minimizeControl()
        else
            layerSwitcher.maximizeControl();

this is compatible with the layer switcher control button (class:
olControlLayerSwitcher)


regards, Huub

Thanks to Andreas & Bryan for the pointers. I did eventually find 
august's AGS work in 
http://trac.openlayers.org/browser/sandbox/august/trunk/lib/OpenLayers/Control. 
There appears to be support for Find, Identify, Query, Route, 
Geoprocessing, and several other AGS functions. There also seems to be a 
dependency on the ESRI JS API...

Hello,

I'm using WFS Protocol on a vector layer (as per the example) to plot 
data on the map from a wfs server:

	var geographic = new OpenLayers.Projection("EPSG:4326");
              var layer = new OpenLayers.Layer.Vector("WFS", {
                 strategies: [new OpenLayers.Strategy.BBOX()],
                 protocol: new OpenLayers.Protocol.WFS({
                 url:  "http://mapserver.worldflightplanner.com/radar/",
                 featureType: "flightrules",
		featureNS: "http://mapserver.gis.umn.edu/mapserver",	
		featurePrefix: "ms",
		version: "1.1.0",
		geometryName: "location",
		srsName: "EPSG:4326",
		extractAttribute: true
         	}),projection: geographic
            });

This works fine, however, the returned GML from the WFS does not contain 
any coordinates, just the metadata. Is this something wrong with my 
Mapserver configuration, or my OL call?

You can see the request, and the returned data here:

Hi,

 

I have never used OpenLayers and would appreciate any help to
get started. My first question is about using my own base layers and overlays. Some
of my base layers are in .TIF format and others are in MapInfo format. Some
data are raster layers and some vector layers. The same applies for overlays.
Could somebody  tell me what I need to do
with these data i.e. in what format they have to be stored in order to be
properly displayed in OpenLayers? Any help will be grately appreciated.

 

Thanks,

 

Armin

Hi Armin,

OpenLayers supports several different layer types.  Have a look at the 
http://dev.openlayers.org/releases/OpenLayers-2.9.1/doc/apidocs/files/OpenLayers-js.html
Class Documentation  under the Layer section.  Depending on the size of your
raster layers, you may be able to load them directly as an Image Layer- see 
http://openlayers.org/dev/examples/image-layer.html
http://openlayers.org/dev/examples/image-layer.html .  If they are large
images, you will probably want to cut them into tiles- see 
http://www.maptiler.org/ Map Tiler .

The same general rule applies for your vector data.  Smaller, less complex
datasets may be loaded directly as a vector layer (KML, JSON, GML, Text,
etc), while larger datasets will require some server side processing.  You
could use GeoServer to render your files as WMS overlays in OpenLayers, or
you could load the data into a spatial database (PostGIS/MySQL) and write a
PHP script to call just the bits you need to fill the map viewport.

Hope this helps to get you started...

Message-ID: <004701cafdb7$e7dfd950$b79f8bf0$@com>

Hi folks,

 

I am new to OpenLayers and I wanted to get some rough feedback on an
implementation I have in mind.  

 

We would like to collect information from the public as points and
possibly polylines.  I would like to use OpenLayers to display the
basemap and for the user to input data using the geometry tools.  As
far as storing that data, would it be feasible to use a public Google
Spreadsheet to store the data?  The idea of having everything client
side (and on Google's server side) is appealing.  Or is it better to
have that data entered into a PostGIS database?

 

Any tutorials on the web that you could point me to would be helpful.
Thank you for your feedback.

 

Benjamin Sigrist

Subject: [OpenLayers-Users] Custom OpenLayers Graphic Names with multiple
	vector features
Message-ID: <AANLkTikCQRI8PTB76wMQbmzuvPqtkPblWyeJuQYHxAzd@mail.gmail.com>

Dear all, at present the graphic-name.html example from OL2.9 examples shows
us how to add a custom graphic name, as follows:

OpenLayers.Renderer.symbol.lightning = [0,0, 4,2, 6,0, 10,5, 6,3, 4,5, 0,0];
and
OpenLayers.Renderer.symbol.rectangle = [0,0, 4,0, 4,10, 0,10, 0,0];

1. My first question is , how can we add a feature with multiple
vector features, e.g. i found an example in geoext 0.7
http://dev.geoext.org/trunk/geoext/examples/renderer.html which can
draw multiple vectors in a single feature as following:

Geometry Well-Known Text : POLYGON((1 30, -33 10, -39 -21, 1 -41, 23
-22, 27 15, 1 30), (0 10, -14 0, -4 -24, 12 -8, 0 10))

How we can achieve the same in OL?

2. I want to achieve following: Once i add a vector layer feature on a
click event, the actual symbol is drawn above the point of click,
and it is connected with the point of click with a vector line. Also
when i drag the drawn vector feature the line's one end remains at the
point of click, while the other end is 'fastened' to the vector
feature. How this can be achieved in OL ?

Thanks in advance....

Any help will be welcome, especially if some code example can be given, thanks.

Hi Ben,

You may be able to get away with using Google Spreadsheets to store point
data, but I'm not quite sure how you would handle polyline geometries.  You
may want to look into the 
http://code.google.com/apis/maps/documentation/mapsdata/ Google Maps Data
API , which basically exposes the My Maps storage platform.  Alternatively,
you could have your editors use Google My Maps to edit a collaborative KML,
which could be referenced in your OpenLayers application.

Depending on the scope of your application, you could use PostGIS or even
MySQL Spatial to store your VGI.  You'd still have to write some scripts to
spit the data out of the database in an OL friendly format (KML, JSON, etc). 
I guess a lot depends upon how sophisticated your data collection
application needs to be and what level of information you are trying to
collect.

Very helpful, thanks!
I'm trying to do something like that but I don't understand how to perform
the script; I'll try to explain me better:

   1. Extract the data from db with a query -> "select * from ..."
   2. Create the variables
   3. Write my html code and create a structure like a csv (first row as
   title and then the data)

Could works?

bye

Hi all,

I have problem when drawing circles on google map layer.

I simply edit this google example

http://www.openlayers.org/dev/examples/google.html

for drawing circle I added

polygonLayer = new OpenLayers.Layer.Vector("Polygon Layer");

var polyOptions = {
                sides :40
};

 polygonControl = new OpenLayers.Control.DrawFeature(polygonLayer, 
OpenLayers.Handler.RegularPolygon, {
                handlerOptions :polyOptions
        });
 
map.addControl(polygonControl);


after this circles drawn as expected  but when panning up and down side on 
 map , circles positions are broken.

Any solution for this
Thanks.

Dear OpenLayers Mailing List,

I am sorry if this has been already covered in previous posts: 

I would like to share maps online, on a high resolution imagery background, and permit visitors (average pc users) in an easy manner to draw and/or add text comments to the maps, and then share again with the map user list (as in commonly used proprietary software).

---
Is there any website offering that with OpenLayers, so an average pc user, can log in, draw maps, post comments and share with a specific map user list?

Thanks,

Dimos

Android (and most touch browsers) do not support/implement mousemove events based on dragging in the map. There has been some work towards improved touch-based navigation for iPhone using Apple-generated touch events. Assuming the android browser implements similar properties, this effort could also help on Android.

Hi,
If you want (can) to use the WMTS RESTFul interface, you can use:

var layer = new OpenLayers.Layer.XYZ(layerName,
                    "http://wmtsPath/${z}/${y}/${x}.jpeg", jpegOptions);


Hope this helps.
I would be interested to know if there are open (RESTFull) WMTS servers
available.
C?dric

There is a good PHP/MySQL tutorial written by the Google Geo Team you may
want to check out here: 
http://code.google.com/apis/maps/articles/phpsqlajax.html
http://code.google.com/apis/maps/articles/phpsqlajax.html .

This method uses PHP to echo XML, but should get you started in the right
direction.  Keep in mind if you are storing spatial geometries you will need
to convert them to WKT using a function like AsText(the_geom).

Hi C?dric

 

Thanks for your reply. I will try to use the XYZ layer class. 

The WMTS I am testing is unfortunately not open, but it would be nice to have open WMTS server.

 

I just realised that there are a ticket about adding a new WMTS layer class here: 

http://trac.openlayers.org/ticket/2637

 

The WMTS service that I am testing have KVP (Key-value-pairs) as parameters so maybe a WMTS layer with parameters is a better option for me.  

Anyway I will try the XYZ class.

 

Esben

I need to zoom to features based on values in a postgis database.   Is it
reasonable to a throw a query at a servlet that queries the database and
returns the extent, which I then zoom to?  I don't want to go this route if
there are easier/better ways to accomplish this.   PHP is not an option. 
Thanks for any help or comments.

If you are running GeoServer you can make a WFS request, which will return
the BBOX for the feature queried.  The nice thing about this approach is
that you don't have to write any server side scripting- you can just use
JavaScript to piece together the variables needed to build the WFS URL.

Thanks for the quick reply.   I am running geoserver.   Can you make
attribute queries with wfs?  The wfs query examples I've seen are all
spatial queries.

Sure- you can use simple CQL_FILTER queries in your WFS request...

http://suite.opengeo.org/geoserver/wfs?service=WFS&version=1.0.0&request=GetFeature&typeName=usa:states&CQL_FILTER=STATE_NAME='New
York'&outputformat=json

Just make sure to tick the "Return bounding box with every feature" box in
your WFS settings in GeoServer.  

I use this technique for querying attributes and returning the results to an
ExtJS grid.  One of the columns in my grid is a "Map" link, which calls a
map.zoomToExtent function, based on the bbox values returned.  You may also
want to check out the 
http://docs.geoserver.org/stable/en/user/tutorials/cql/cql_tutorial.html?highlight=cql
GeoServer CQL Documentation .

Subject: [OpenLayers-Users] newbie questions
Message-ID: <4C002163.60600@ufl.edu>

I've built my first OL map, but encountered some quirky behavior with 
certain controls. All symptoms are present in Chrome, Firefox, and IE 8.

a. No alpha transparency for Navigation or ScaleLine control images.
b. Scroll wheel does not zoom in/out.
c. Adding an OverviewMap control causes the main map to be blank. The 
overview map is also blank. I'm adding a single layer (the only layer) 
to its layers array.

I'll gladly post code if that would help.

Hi Blake,

You can work around this issue by providing the property names 
explicitly in the options of your protocol, including the name of the 
geometry.
Example:

     propertyNames: 
'year,seq,name,storm_start,storm_end,msGeometry'.split(',')

Note that MapServer by default chooses 'msGeometry' as the name of the 
geometry attribute even though it might be called 'the_geom' or 
'wkb_geometry' on the data source. In your case it's 'location' I presume.

Regards, Roald

Subject: [OpenLayers-Users] Problem with Vector_points from WFS Geoserver
Message-ID: <4C014C67.4020308@poczta.onet.pl>

Hello OLusers

I have probelm with confusing display bahavior of vectorlayer from 
goeserver as WFS.
I created a rasterlayer from Mapserver and vector layer from Geoserver 
as folows:

var options = {
                     projection: new OpenLayers.Projection("EPSG:2180"),
                     units: "m",
                     maxResolution: 10,
                     maxExtent: new 
OpenLayers.Bounds(545440,226900,586250,261950)
                 };

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

                 var topo = new OpenLayers.Layer.WMS( "Mapa 
topo","http://myserver/cgi-bin/wms?",
                     {layers: 'topo', format: 'image/png',projection: 
"EPSG:2180" },{'buffer':0} );

                 map.addLayers([topo]);

                 wfs = new OpenLayers.Layer.WFS(
                     "WFS czysty",
                     "http://myserver:8080/geoserver/wfs",
                     {typename: 'komunikacja:przystanki_mk'},
                     {
                         typename: "komunikacja:przystanki_mk"
                         //featureNS: "http://www.openplans.org/topp",
                         //extractAttributes: false,

                     }
                 );

                 map.addLayers([wfs]);

The topo layer displays correctly in all cases. Wfs-layer don't displays 
points in Mozilla 3.6.3. In IE 8 I see my vectorpoints correctly.
Please tell me wat should I add to my code to see vectorlayer in Mozilla?

In the geoserver log I see:
/geoserver/wfs?TYPENAME=komunikacja%3Aprzystanki_mk&SERVICE=WFS&VERSION=1.0.0&REQUEST=GetFeature&SRS=EPSG%3A2180&BBOX=559123,241606,572573,247236

Also the geoserver give me the gml file and I can see this as
http://myserver:8080/geoserver/wfs?TYPENAME=komunikacja%3Aprzystanki_mk&SERVICE=WFS&VERSION=1.0.0&REQUEST=GetFeature&SRS=EPSG%3A2180&BBOX=562938,243383.5,569768,246168.5

I tried to define point layer as vectorlayer with protocol WFS (as I 
found in OL discussions):

var przystanki_wfs = new OpenLayers.Layer.Vector("WFS przystanki 
protocol", {
                         strategies: [new OpenLayers.Strategy.BBOX()],
                         protocol: new OpenLayers.Protocol.WFS({
                         //protocol: new OpenLayers.Protocol.WFS.v1_1_0({
                             url:  "http://myserver:8080/geoserver/wfs",
                             featureType: "komunikacja:przystanki_mk", 
//featureType    {String} Local (without prefix) feature typeName 
(required). //TYPENAME=komunikacja:przystanki
                             //featureNS: "komunikacja", //featureNS    
{String} Feature namespace (optional). "http://opengeo.org" 
"http://postgis.org"
                             //featurePrefix:"komunikacja" , //Feature 
namespace alias (optional - only used if featureNS is provided).  
Default is ?feature?.
                             //featureNS: "komunikacja",
                             srsName: "EPSG:2180",
                             version: "1.0.0" //version: "1.1.0
                             //schema: 
"http://myserver:8080/geoserver/wfs/DescribeFeatureType?version=1.1.0&typename=komunikacja:przystanki",
                         })
                     });
                     map.addLayers([ przystanki_wfs]);

Now I see no one point in this layer in Mozilla and no one in IE

When I display the layer przystanki_wfs in Mozilla I see that Geoserver 
logs has new lines:

91.150.223.134 -  -  [29/maj/2010:16:52:22 +0000] "OPTIONS 
/geoserver/wfs HTTP/1.1" 200 0
91.150.223.134 -  -  [29/maj/2010:16:52:24 +0000] "OPTIONS 
/geoserver/wfs HTTP/1.1" 200 0

When I show the new layer in IE the log looks like so:
91.150.223.134 -  -  [29/maj/2010:16:54:39 +0000] "POST /geoserver/wfs 
HTTP/1.1" 200 23047
91.150.223.134 -  -  [29/maj/2010:16:54:56 +0000] "POST /geoserver/wfs 
HTTP/1.1" 200 19968

I tried change the version of WFS: to version: "1.1.0",
enter a schema: as: schema: 
"http://myserver:8080/geoserver/wfs/DescribeFeatureType?version=1.1.0&typename=komunikacja:przystanki",
change the: strategies: [new OpenLayers.Strategy.Fixed()],
It don't helped.

I generated the gml file from Geoserver log
/geoserver/wfs?TYPENAME=komunikacja%3Aprzystanki_mk&SERVICE=WFS&VERSION=1.0.0&REQUEST=GetFeature&SRS=EPSG%3A2180&BBOX=559018,241636,572678,247206

and defined the layer as GML layer
var gml = new OpenLayers.Layer.GML("GML", "przystanki_gml.xml", {
                        format: OpenLayers.Format.GML
                     })
                     map.addLayer(gml);
Now I see the points correctly in Mozilla and in IE.

Pleace tell me what I'm doing wrong. I would like to user geoserver as 
WSF-T to edit the points. What is the reason of so confusing behavior.

Thanks

Bartek

Hi Roald,

Adding propertyNames (attributes of the feature) to the protocol solves the
problem with the geometry for MapServer 5.6.1. First I thought it wouldn't
work, because i added msgeometry instead of msGeometry. And I have to add
srsName to the protocol, what for version 5.2 is not needed.

thx
Arnd

Hi Blake,

You can work around this issue by providing the property names explicitly in
the options of your protocol, including the name of the geometry.
Example:

     propertyNames: 
'year,seq,name,storm_start,storm_end,msGeometry'.split(',')

Note that MapServer by default chooses 'msGeometry' as the name of the
geometry attribute even though it might be called 'the_geom' or
'wkb_geometry' on the data source. In your case it's 'location' I presume.

Subject: [OpenLayers-Users] Layer.XYZ tiles from ArcGIS Server not lining up
	with other	 layers
Message-ID: <4C039EC5.379F.0037.1@asurequality.com>

This is a resend, as I have not had any responses. Tiles I request from an ArcGIS Server cache using Layer.XYZ are not lining up with other layers requested from the same server via Layer.WMS or Layer.ArcGIS93Rest. 
 
Instead of making use of tileOrigin (which doesn't seem to get used), we make sure the Origin as reported by ArcGIS is contained within the maxExtent, and then use restrictedExtent to constrain the map area to the are we want OL to work within:
 
var mapoptions = {
  //tileOrigin: new OpenLayers.LonLat(-4020900,19998100), //Origin as reported by ArcGIS
    maxExtent: new OpenLayers.Bounds(-4020900, 4674128.11975, 2568710.79993, 19998100), //contains the AGS origin
    restrictedExtent: new OpenLayers.Bounds(1018697.71047, 4674128.11975, 2568710.79993, 6296981.53325),
    resolutions: new Array(3175.0063500127, 793.751587503175, 264.583862501058, 198.437896875794, 132.291931250529, 66.1459656252646, 26.4583862501058, 19.8437896875794, 13.2291931250529, 9.26043518753704, 6.61459656252646, 5.29167725002117, 3.96875793751588, 2.64583862501058, 1.98437896875794, 1.32291931250529),
    tileSize: new OpenLayers.Size(256,256),
    units: 'm',
    projection: new OpenLayers.Projection('EPSG:2193'),
    fractionalZoom: false
};
var map = new OpenLayers.Map( 'map',mapoptions );
var nzcoastwms = new OpenLayers.Layer.WMS( "Coastline",
                          "http://ws-esrimt/arcgis/services/mapservice_asurequality_prod/MapServer/WMSServer",
                          {layers: ['0'], format: "image/png"},
                          {isBaseLayer: true, singleTile:true, visibility: true,
                           attribution:"LINZ data Crown copyright reserved"} );
var topoxyz = new OpenLayers.Layer.XYZ( "Topo",
                    "http://ws-esrimt/ArcGIS/rest/services/mapservice_topography_vector_prod/MapServer/tile/${z}/${y}/${x}",
                   {isBaseLayer: false, sphericalMercator: false//, tileOrigin: new OpenLayers.LonLat(-4020900,19998100)
});
map.addLayers([nzcoastwms,topoxyz]);

Doing this above, requests the correct tiles, but it seems the requested tiles are displaced in a north-south direction. The displacement seems different depending on zoom level. The latter is sometimes displaced to the north, and sometimes to the south, depending on Zoom level. I have previously verified the WMS layer is in the correct location. 
 
Many thanks,
 
Robert Sanson

have you included proj4js? otherwise I'm pretty sure setting the
projection doesn't do anything

Hello,

I have a draw feature control drawing linestrings, that I want to
trigger programmatically, without having to do a mouse down from
starting position. 

I want to start the line drawing from some coordinates and then let the
user click to set the other extremity?

Hello,


Appears that my question hasn't appeared in the list yet, so reposting.


Tried different examples but the image is still showing up streched --
http://skip.nonsense.ee/.dev/openlayers/

With JOSM everything is working -- image is displayed in EPSG:3857 and
WMS images get asked in EPSG:4326 as it should...


How to fix?

Hi,

several things are wrong in your code.

* Looking at your WMS Capabilities, I see that only EPSG:3301 is supported for your layers.

* OpenLayers does not do client side reprojection

* displayProjection is only there to tell controls in which coordinate system they should display coordinates

* maxExtent has to be provided in coordinates of the map projection.

So I'd configure the map like this:

var options = {
projection: new OpenLayers.Projection("EPSG:3301"),
displayProjection: new OpenLayers.Projection("EPSG:4326"),
units: 'm',
'maxExtent': new OpenLayers.Bounds(
370753.1145, 6382922.7769, 739245.6000, 6624811.0577
),
'maxResolution': 'auto'
};

I took the maxExtent from the Projected Bounds found here: http://spatialreference.org/ref/epsg/3301/

Regards,
Andreas.

Now it stopped working at all -- see
http://skip.nonsense.ee/.dev/openlayers/ahocevar@opengeo.org.html


I can see that OpenLayers is sending now WMS requests with
SRS=EPSG%3A3301&BBOX=370753.1145,6382922.7769,561216.32772835,6573385.9901283

But it should send them with
SRS=EPSG:4326&bbox=24.6461274,59.3624859,24.6479219,59.3634004

Like:

Subject: [OpenLayers-Users] how to choose layers and "tile is undefined"
	error
Message-ID: <AANLkTimKGVmVs5oGD3KfSmzyrtThvuZhjIkwRw_-kcV-@mail.gmail.com>

Hi, I'm working with OL and arcIMS.
Actually I can connect to arcIMS server but cannot load the layers I need.
Here a snippet of my code (copied from examples)

[..]
layer = new OpenLayers.Layer.ArcIMS(
            "Global Sample Map",
            "http://www.mydomain.com/servlet/com.esri.esrimap.Esrimap",
            {
                serviceName: "myService",
                layers: [
                    // layers to manipulate
                    {id: 2, visible: true},
                    {id: '5', visible: true},
                    {id: "11", visible: true},
                    {id: 12, visible: true}
                ],
                async: true
            }
        );
[..]

I know this service has layers with IDs from 0 to 15. Some are image layers,
others are featureclass.
In my browser I see only one layer, and it is the only layer which hasn't a
numeric id but a textual id.
Looking at firebug console I get "tile is undefined" error

Can someone help me with this issue?
How can I set visible layers?

thank you
Alberto

Looking at your WMS Capabilities again, I see that the 'of10000' layer does not support EPSG:3301. Remove it from the "layers" list, and you should be fine.

Also note that displayProjection will display your coordinates in EPSG:3301, because OpenLayers cannot transform from 3301 to 4326. But all you have to do is to include proj4js (google for it), and add the proj4js definition from the spatialreference.org link I posted in my first reply to your js code.

Regards,
Andreas.

Yes. However, all the data is in New Zealand Transverse Mercator (2193), so there is no re-projection work being done.

have you included proj4js? otherwise I'm pretty sure setting the

I have been trying to figure this out for 2days and it is driving me nuts. 
I have a wms server which has hard bounds of -180,-90 to 180,90, ie I cannot
make requests beyond e end of the world!

I can see the data in openlayers if I use single tile, but I am having
trouble with tiled requests.  The tile origins are not at even spacings from
the origin.  I would have thought the low resolution requests would be at 90
degree tile spacings, but they are about 92 degrees.  By the time we get
across the globe, the last tile is asking for data at 188 degrees long, when
it should be adhering to my layer and map bound of 180.0

Is there any way I can control the origin and tile size, so I can force
openlayers to always ask for consistent tile origins?

here is my code...

            var enc_wms = new OpenLayers.Layer.WMS(
					"ENC WMS", "http://172.23.21.4/WMS/wms.ashx",
                    {
						layers: 'ENC' , 
						//Width: '256',
						//Height: '256',
						//tilesOrigin: "-180.0, -90.0" ,
						//tiled: 'true' , 
						srs: 'EPSG:4326',
						styles: ' ',
						format: 'image/png',
					},
					
					{	
						//wrapDateLine: true,
						//buffer: 0,
						maxResolution: 1.40625,
						//minExtent: new OpenLayers.Bounds(-180, -90, 180, 90),
						//maxExtent:[-180,-90,180,90],
						maxExtent: new OpenLayers.Bounds(-180, -90, 180, 90),
						resolutions:[1.40625,0.703125,
0.703125,0.3515625,0.17578125,0.087890625,0.0439453125,0.02197265625,0.010986328125,0.0054931640625,0.00274658203125,0.001373291015625,0.0006866455078125,0.00034332275390625,0.000171661376953125,0.0000858306884765625,0.00004291534423828125,0.000021457672119140625],
						displayOutsideMaxExtents: false,
						isBaseLayer: false, 
						transitionEffect: 'resize', 
						//ratio: 1 
					});

As you can see from the image, the lower left corner of the tile is NOT at a
predictable origin, whihc in this case should be 90W.
