Re: [OpenLayers-Users] how to limit to 1 the number of points of a vector layer
Hi,
you could do something like:
1) use sketchstarted event to limit the number of features to 1
2) use the featureadded event to set your form field
Example code (just for reference, copy/paste from another project):
new OpenLayers.Layer.Vector(Sketch, {
displayInLayerSwitcher: false,
eventListeners: {
sketchstarted: function(evt) {
// make sure there is only 1 feature at a time
vector.destroyFeatures();
},
featureadded: setFormValues,
scope: this
}
});
var setFormValues = function(evt) {
var geometry = evt.feature.geometry;
var form = document.forms[this.formid];
var toProjection = new
OpenLayers.Projection(form.elements[epsg].value);
geometry =
geometry.clone().transform(map.getProjectionObject(),
toProjection);
var points = geometry.getVertices();
var x = points[0].x;
var y = points[0].y;
form.elements[x].value = x.toFixed(2);
form.elements[y].value = y.toFixed(2);
form.elements[directionAngle].value =
this.calculateAngle(geometry);
}
Best regards,
Bart
hi all,
starting from the Drag-feature example (
http://openlayers.org/dev/examples/drag-feature.html) I need to limit to 1
the number of points which can be added to the vector layer
if the user, after having added one point, clicks again, the first point
is
deleted and only the newly created remains.
I need this for localization purpose: i.e. Dear User, tell me where
THAT_THING is so the position must be unique.
I also need to extract coordinates from the point
(document.getElementById(x_coord).value = ???)
Can anyone help me?
thank you in advance!

Do you add the control before adding your layers?
Does it work when you zoomin?
What do you see with Firebug?
Bart
.olControlLoadingPanel {
background-image: url( ./img/loading.png);
position: relative;
width: 195px;
height: 11px;

Re: [OpenLayers-Users] Is it possible to show a subsection (sprite) of an image as a marker?
Hi Matt, not out of the box unfortunately. This would either require changes to the current renderers (SVG and VML), or implementing your own custom renderer. I did something like this a while ago, see: http://osgisjs.blogspot.com/2010/06/anchor-renderer.html Best regards, Bart My application has 100 marker images that I want to display on the Map. I don't want to force to user to download 100 images. A technique that has worked for other graphic intensive sites, is to send all the markers down as sprites in a single image (http://www.alistapart.com/articles/sprites), and use CSS to control which part of the image is shown for every marker. Does OpenLayers have support for these sorts of techniques in the Vector Layer? If not, is it possible to use custom html as a marker instead of a graphic? -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/Is-it-possible-to-show-a-subsection-sprite-of-an-image-as-a-marker-tp5435420p5435420.html Sent from the OpenLayers Users mailing list archive at Nabble.com. ___ Users mailing list Users@openlayers.org http://openlayers.org/mailman/listinfo/users -- Looking for flexible support on OpenLayers or GeoExt?

Re: [OpenLayers-Users] Markers with dymamically changing appearance
Hi, have you considered using a vector layer with an externalGraphic instead? It should be fairly easy to change the appearance of that through the asscioated styles and redraw the features. Best regards, Bart New to Openlayers. Great project, many thanks to all who put so much work into creating and documenting it! What would be the idiomatic way to have the markers on my map with part of their appearance being dynamically generated and changeable? This is to display relative temporal information on the markers: as the user changes their location in time instead of space, using controls outside of the map itself, I need my markers to change their appearance in a dynamically-generated (ie local javascript) fashion. It would be possible to have a fixed set of graphics that they switch between, but there would be a largish number of these, so it would be preferable to just generate them locally via Javascript. Best of all possible worlds would probably be to fetch a base marker and then copy it, add the custom graphic as a layer on top of it, drop it on the map, then be able to get at it and just change its custom layer with javascript drawing commands (I'm okay with having to use HTML5 for this, but I'd prefer not to). The graphic I want to draw on top of the marker isn't complicated two or three lines at right angles, so I should be able to dynamically update even a fair number of markers assuming there isn't a massive drawing overhead. ___ Users mailing list Users@openlayers.org http://openlayers.org/mailman/listinfo/users -- Looking for flexible support on OpenLayers or GeoExt?

Re: [OpenLayers-Users] Implementing a layer for a proprietary WMS-like service
It does not seem an ideal design to me. Is there no way to provide caching (maybe by setting the correct http headers) so that the backbuffer tile will come from the browser's cache? Or are your async requests using POST and not GET? Best regards, Bart I dropped my plans of extending ImageLayer...the getUrlAsync approach leads to the same problem than with GridLayer (multiple image requests during zoom/pan animation). However I have a new idea: what if I manage the layer through a control? It could perform the map request, parse out the map image bounds and url and then add an ImageLayer with the requested image to the map. If the image layer gets moved, it would trigger a map request through the control. When the map response arrives, the control removes the current layer and adds a new layer to the map. Any thoughts on that? Franz 2010/8/3 Franz Buchinger fbuchin...@gmail.com In my case, creating the single-tiled map is rather expensive - because the map image is generated on-the-fly. Therefore, I want my layer to anticipate the map action (zoom, pan), just like the ImageLayer does. I actually had a well working implementation of my map viewer based on ImageLayers, but all the logic (requesting new map etc) happened outside the layer and caused side-effects with other layers. I'm wondering if it would be better to derive my ProprietaryMapLayer from ImageLayer. I could extend it with a getUrlAsync method that fetches the map image url based on the new extent after a map action was performed. Would that work?

I noticed that these multiple requests only happen when I set transitionEffect: 'resize'. This is basically expected. The transition effect creates multiple tiles, and since creating images is generally considered to be 'cheap' in OpenLayers -- since images should be served from cache -- we just create more tiles, rather than copying existing ones in any way.

Hello everyone.
I am listening the changelayer event on map.events like this:

changelayer: function(e) {
if(e.property === visibility) {
alert(e.object.baseLayer.name);
}
}
});
the problem here is, when i check the the baseLayer.name via
console.log(e)
I see the newly selected layer's name but when I use alert() I get the
previously selected layer's name.
my goal here is to get the newly selected layer's name and index from the
layer switcher. any help or direction is appreciated.
thanks in advance.

Re: [OpenLayers-Users] SphericalMercator and SRS aliases epsg:900913, epsg:3857, epsg:3785, epsg:102113
Hi Anne, in trunk this has been addressed, see: http://trac.openlayers.org/ticket/2665 Best regards, Bart Hello list, OpenStreetMap and also some popular commercial mapservices (google, bing, yahoo) are using the so called sphericalmercator projection. OpenLayers has built-in support for this type of layer, inherited from OpenLayers.Layer.SphericalMercator. If you use a sphericalmercator layer as a baselayer, you may want to combine this with other layers. By default, the openlayers sphericalmercator baselayer uses SRS projection-code 'EPSG:900913' . So, if you try to open an overlay, the overlay layer will be called with parameter SRS=EPSG:900913. EPSG Code 900913 happens to be a bogus code, based on the word 'google'. Perhaps due to the resemblance of '900913' and 'google' or due to other reasons, there are now several other codes in use for the same projection: EPSG:3857 EPSG:3785 = maybe because of a typo by someone somewhere? EPSG:102113 Some map-services have stopped supporting SRS=EPSG:900913 and this raises a problem for openlayers sphericalmercator users. Instead of displaying a map, these mapservices will respond with something like 'no support for EPSG:900913'. The problem of overlaying sphericalmercator layers that do not support epsg:900913 can be (partly) solved as follows: Override the default srs code for sphericalmercator layers by explicitly resetting the projection before adding the layer to a map: var osmLayer = new OpenLayers.Layer.OSM(OpenStreetMap); // osmlayer is now sphericalmercator with default epsg:900913 osmLayer.projection = new OpenLayers.Projection (EPSG:3857); // osmlayer is now sphericalmercator with epsg:3857 map.addLayers ([osmLayer]); Overlay layers will now be requested with SRS=ESPG:3857 However, resetting the code for the baselayer projection, causes trouble for the controls for MousePosition and MeasureControl: distances and coordinates are no longer presented in the correct projection. I solved this by adding the following lines of code to file lib\OpenLayers\Layer\SphericalMercator.js OpenLayers.Projection.addTransform(EPSG:4326, EPSG:3857, OpenLayers.Layer.SphericalMercator.projectForward); OpenLayers.Projection.addTransform(EPSG:4326, EPSG:102113, OpenLayers.Layer.SphericalMercator.projectForward); OpenLayers.Projection.addTransform(EPSG:4326, EPSG:3785, OpenLayers.Layer.SphericalMercator.projectForward); OpenLayers.Projection.addTransform(EPSG:3857, EPSG:4326, OpenLayers.Layer.SphericalMercator.projectInverse); OpenLayers.Projection.addTransform(EPSG:102113, EPSG:4326, OpenLayers.Layer.SphericalMercator.projectInverse); OpenLayers.Projection.addTransform(EPSG:3785, EPSG:4326, OpenLayers.Layer.SphericalMercator.projectInverse); Questions: - is this the way to support aliases for 900913 and support MousePosition and MeasureControl at the same time? - if yes, shouldn't the above lines be part of the standard OpenLayers distribution?

Re: [OpenLayers-Users] MapFish vs OpenLayers
If you are only interested in the client-side, I would suggest looking at GeoExt: http://www.geoext.org Best regards, Bart Hello Bart and Hugo, I'm new with MapFish, I've just installed and done some basic tests. First of all, I don't understand how it works pylons virtual environment. Anyway, I'm interested in client side of MapFish to build a Rich web mappinng application. Now We use OL over an apache server and it's a clear and tipical structure of files and data. When We need to create a new component, we extends OL classes creating new js files. Server side components are created using servlets or php and client comunicates with them using ajax. I don't understand how the same can be do it with MapFish. I think there are a great dependency with python server environment.

Re: [OpenLayers-Users] Working with Openlayers.Layer.Vector and WFS
Without seeing your actual WFS it is hard to help.
But here it goes:
1) featureType should be MonkeyIsland
2) check if your featureNS does not end with / in the XML returned by your
WFS, this would also break the parser. So maybe
http://www.mapinfo.com/wfs/ instead of http://www.mapinfo.com/wfs
Best regards,

Hello
I'm having a real hard time changing my OpenLayers.Layer.WFS request to
the
OpenLayers.Layer.Vector with OpenLayers.Protocol.WFS. I've been reading
and
experimenting all available examples that I was able to find and the API
documentation (wich, by the way, didn't help very much) for 2 days now and
couldn't get it to work.
So, please, can someone tell why this old fashion request has a
successfull
response:
var wfs = new OpenLayers.Layer.WFS(Guybrush Threepwood,
http://localhost:2006/GetFeature.ashx;,
{ typename:
miwfs:MonkeyIsland
}, { 'projection': new
OpenLayers.Projection(EPSG:4326)
, 'displayProjection': new
OpenLayers.Projection(EPSG:4326)
, 'maxExtent': new
OpenLayers.Bounds(-9.517034, 36.961718, -6.189968, 42.15434)
, 'maxResolution':
156543.0339
, 'numZoomLevels': 21
, 'minZoomLevel': 1
, 'maxZoomLevel': 21
, 'units': dd
, 'encodeBBOX': true
, 'displayOutsideMaxExtent':
true
, 'styleMap': layerStyle
, 'extractAttributes': true
}
);
map.addLayer(wfs);
But this one, that I found somewhere in the examples or forums, doesn't:
var layer = new OpenLayers.Layer.Vector(Guybrush Threepwood, {
strategies: [new OpenLayers.Strategy.BBOX()],
protocol: new OpenLayers.Protocol.WFS({
version: 1.1.0,
url: http://localhost:2006/GetFeature.ashx;,
featureType: miwfs:MonkeyIsland,
featureNS: http://www.mapinfo.com/wfs;,
geometryName: VL_GMTR,
srsName: EPSG:4326
}),
projection: new OpenLayers.Projection(EPSG:4326)
});
map.addLayer(wfs);
If helps, my map object is:
var map = new OpenLayers.Map(map, {
projection: new OpenLayers.Projection(EPSG:900913),
units: m,
maxResolution: 156543.0339,
maxExtent: new OpenLayers.Bounds(-20037508.34, -20037508.34,
20037508.34, 20037508.34),
numZoomLevels: 21
});
and my baseMap is:
var myBaseLayer = new OpenLayers.Layer.Google(Google,
{ 'sphericalMercator': true
, 'numZoomLevels': 21
, 'minZoomLevel': 1
, 'maxZoomLevel': 21
});
map.addLayer(myBaseLayer);
Sorry for the long post.

Re: [OpenLayers-Users] Set Bbox of WMS request
If you want the BBOX to be exactly the visible part, use ratio 1 and
buffer 0 in the layer options.
So:
var layer = new OpenLayers.Layer.WMS(null, url, {layers: 'foo'},
{singleTile:true, buffer:0, ratio:1});
Best regards,
Bart
Ok Ian, right. (Thanks)
So you mean that you would download also data outside the viewport in
certain cases?
But, especially if the BBOX is small, this wouldn't be a huge problem.
Or am I missing something?

Re: [OpenLayers-Users] WMS Map request
Hi,
use singleTile: true and ratio: 1 in your layer options.
Best regards,
Bart
Hi Group,
I am trying to configure my WMS service with OpenLayers. My script looks
below
script type=text/javascript
//var map = new OpenLayers.Map('map',{maxResolution: 1000} );
var map = new OpenLayers.Map('map', {
maxExtent: new OpenLayers.Bounds(
-638480920.244,-188017611.367,665489491.580,1019789790.73), maxResolution:
500 } );
var wmsURL =
http://localhost:8080/gss/ogc?version=1.3.0crs=sw:nsw_trans_mercator_mm;;
var myLayer = new OpenLayers.Layer.WMS( 'CE SL' , wmsURL , { layers:
'background', styles: 'Default' } , { buffer: 1 , isBaseLayer: true } );
map.addLayer( myLayer );
map.zoomToMaxExtent();
/script
It should actually send only one WMS request for the first time and then
act
according to uses operations like Pan , Zoom. But, that is not how it's
working. Everytime when I open this html file, it's sending 48 WMS
requests
and creating 48 image files in the resources folder and none of these
images
are turned up on the browser. Also, surprisingly all those 48 images are
empty with just white background.
Does any one what the problem is ?
Thanks,
Kalyan

Re: [OpenLayers-Users] hardcoded gml:featureMemeber of WFS layer in openlayers ?
Hi,
basically this requires writing your own format, which can extend
OpenLayers.Format.GML.v3.
OpenLayers only supports the GML 3.1.1 Simple Features profile out of the
box:
http://schemas.opengis.net/gml/3.1.1/profiles/gmlsfProfile/1.0.0/gmlsf.xsd
It should not be too hard to write the format. Make sure you add wfsos to
the namespaces array and add a reader function where necessary.
Btw, in your code below you are using the old GML parser.
Best regards,
Bart
hi everyone,
I have a problem adding a WFS request as overlay on the openlayers map.
Is there a way to tell it to search for other featureProperty elements
then the basic gml:featureMember ?
Is it realy hard-coded into the parser source that the featureProperty
name shall be gml:featureMember ?
The WFS service is set up with a GML Application Profile which defines
its FeaturePropertyType as a restriction of the generic
gml:FeaturePropertyType (and similar for the FeatureCollectionType).
This means that the structure of the GML returned from the WFS request is:
wfsos:featureCollection
xmlns:wfsos=http://cweb.ksat.no/cweb/schema/geoweb/oil; ...
schemaLocation=http://cweb.ksat.no/cweb/schema/geoweb/oil ...
wfsos:featureMember
wfsos:feature
wfsos:oilSpill
gml:Polygon srsName=EPSG:4326
It seems that the featureCollection level is ignored (as well as the
schema location - since the schema is not loaded), so that one is not
the problem.
I can set the name space prefix, and element name for the feature
level and the geometry, but can't find any way to do this for the
featureMember level!
If I run this from a file, and change the wfsos:featureMember into
gml:featureMember it works fine (even if it violates the schema).
To repeat the question: Is there any way to instruct openlayers to look
for wfsos:featureMember instead ?
PS:
Here is the code for the WFS request linkage:
wfs_ksat = new OpenLayers.Layer.Vector(id, {
strategies: [new OpenLayers.Strategy.BBOX()],
projection: new OpenLayers.Projection(EPSG:4326),
protocol: new OpenLayers.Protocol.WFS.v1_0_0({
url: ksatWFSuri,
featureType: feature,
featureNS:
http://cweb.ksat.no/cweb/schema/geoweb/oil;,
featurePrefix: wfsos,
geometryName: oilSpill,
srsName: EPSG:4326,
readFormat: new OpenLayers.Format.GML(),
outputFormat: GML2
}),
styleMap: styleMap
});

Re: [OpenLayers-Users] SelectFeature working at the same time in two different overlays?
Use 1 SelectFeature Control and initialize it with an array of layers.
/**

* Create a new control for selecting features.

* Parameters:

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()],
protocol: new OpenLayers.Protocol.HTTP({
url: file.kml,
format: new OpenLayers.Format.KML({
extractStyles: false,
extractAttributes: true
})
})
});
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(
{
featureselected: onFeatureSelect,
featureunselected: onFeatureUnselect
}
);
map.addControl(select);
select.activate();

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?

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

Thanks for the help. I found if(!singleFile) {var jsfiles = new

});
// render grid
grid.render('sentieri-grid');
I populate my grid thanks to a postgis query that encodes the results as
Json with php.
In the estensionegm column I put the geometry bbox (calculated by
postgis), then I put values in the sentExtent var (as you can see in the
code).
the sentExtent alert return the correct values, for example (in spherical
mercator):
1567540.36063275,5196100.3682006,1567671.48470329,5196716.04655338
but when I use the sentExtent var in the new
OpenLayers.Bounds(sentExtent).toBBOX(); it returns only the first value
(xmin) and three zeros:
1567540.360633,0,0,0
so, the map.zoomToExtent(new OpenLayers.Bounds(sentExtent)); can't work!
What I can do?
Thanks, alessio

Hi Bill,
not sure, can you check the css class which has been set on the map
viewport div when you activate a tool? They should have those values.
Maybe there is another class which is preventing the cursors from
showing up.

Hi Bill,
yes it's in 2.8.
You need to add css classes depending on the displayClass + Active

.olControlDragPanActive {

Was support for using different cursor icons (pointer, text, wait,
etc.)
built into version 2.8? I didn't see anything about cursors in the
release notes but I thought there had been some work done on this.
If not, can someone tell me the best place to set the cursor icon for
tool buttons? Is there an on activate event I can listen for, or is
there a better way to do this?

Re: [OpenLayers-Users] GetFeatureInfo with loadURL
Hi James,
yeah after I hit Send I thought just use the function name directly
since there are no extra parameters necessary anymore. So option 1 is
the way to go.
No they are not equivalent, since the second option loses the scope down
the line, and the scope becomes the window object. The only way to keep
the scope would be to use an OpenLayers.Function.bind in between.
Best regards,
Bart

but not with :
OpenLayers.loadURL ( url, '', i, function ( response ) { setHTML (

where I get [object Window] instead of the actual value if i printed out
(as I get with the first declaration).
Aren't those two declarations equivalent ?

Re: [OpenLayers-Users] measure control
Hi James,
the first syntax is OL 2.6, the second is OL 2.7.
I assume you are using a Polygon handler and want to retrieve both the
area and the length?
The event thrown by the Measure control only contains the area in the
evt.measure property in this case, so you have to calculate the length
using something like (untested):
var a = map.getControlsByClass('OpenLayers.Control.Measure');
var ctrl = a[0];
var length = ctrl.getBestLength(evt.geometry)[0];
Hope this helps.
Best regards,
Bart
James Leveille wrote:
Hi,
I'm using the OpenLayers.Control.Measure control.
From the many examples found, the handler declaration can either be :
1) function handleMeasr(geometry, length, area, units) {}
2) function handleMeasr(event) {}
Since I need the area the perimeter, the first one should be the one
to use. BUT, it's not working : I get a length is undefined error
when I try to access the length value (or the area) with that definition.
On the other hand, if I use the second declaration, the
event.measure.toFixed(3) works fine but I can't get the area (there
is no event.area.xxx) ...
Anything special to do to make sure the first declaration gets called
so I can get the area ?
Thanks a lot.

Re: [OpenLayers-Users] buggy loadingPanel (vs Navigation/MouseDefaults) please help!
Hi,
for me it works in the loadingpanel example:
http://dev.openlayers.org/addins/loadingPanel/trunk/examples/loadingpanel.html
It could have to do with the sequence in which you add the controls,
take a good look at the example.

Re: [OpenLayers-Users] buggy loadingPanel (vs Navigation/MouseDefaults) please help!
Hi,
the div size is this big so that the loading panel can be centered in
the map.
Can you please post your complete example HTML to reproduce the problem?
As I said mousewheel navigation works for me in the example when the
loading panel is showing, so I don't get the problem.
Best regards,
Bart
BrainDrain wrote:
of course I know about this example
I think problem is here (loadingPanel):
maximizeControl: function(evt) {
var viewSize = this.map.getSize();
var msgW = viewSize.w;
var msgH = viewSize.h;
this.div.style.width = msgW + px;//WHY?
this.div.style.height = msgH + px;//WHY?
this.div.style.display = block;
this.maximized = true;
if (evt != null) {
OpenLayers.Event.stop(evt);
}
}
div size is very large (div catching mouse wheel event addressed to layer's
divs): it must be equals to size of background img!
changing background-position (in css) to right top just moves background img
(I use smaller one then in example, more sexy) to right top corner but div
size is still big - overlapping map/layer's (tile's) divs
I've change code to
minimizeControl: function(evt) {
this.div.style.display = none;
//this.div.style.width = 0px;
//this.div.style.height = 0px;
this.maximized = false;
if (evt != null) {
OpenLayers.Event.stop(evt);
}
},
maximizeControl: function(evt) {
//var viewSize = this.map.getSize();
//var msgW = viewSize.w;
//var msgH = viewSize.h;
//this.div.style.width = msgW + px;
//this.div.style.height = msgH + px;
this.div.style.display = block;
this.maximized = true;
if (evt != null) {
OpenLayers.Event.stop(evt);
}
},
+ css:
.olControlLoadingPanel {
background-image:url(~/images/default/open-layers/loading.gif);
background-position:center;
background-repeat:no-repeat;
top: 5px;
right: 5px;
width: 16px;
height: 16px;
position: absolute;
}
and zoom wheel works good during tiles loading
but I need to make this more correct (div hiding with resetting size)
so I need to preserve populated from css div size before hiding (minimizing)
and restore on maximize
or I need to find a way to auto-size div by img content (without css)
looking into layerswitcher code we can find this:
maximizeControl: function(e) {
//HACK HACK HACK - find a way to auto-size this layerswitcher
this.div.style.width = 20em;
this.div.style.height = ; ...
)))
Now I'm going to try Sys.UI.DomElement.getBounds function from MS AJAX
client lib.

Re: [OpenLayers-Users] question about OpenLayers.Format.GML.v2
Hey Tim, a use case for us is for instance grouping of entities (e.g. water bodies), which can consist of points, polygons and lines. So we have a typename for points, one for polygons and one for lines. They are grouped as 1 WMS layer. When we want to display the attribute table of that layer, we need to display (features from) 3 typenames. And ofcourse it's a shame to use 3 separate WFS requests for that. Also to search for objects, we sometimes need to go over 15 separate typenames using the same Filter. If we want to display all the details of a certain feature, we also need to query a lot of typenames. Indeed I intend to use the Protocol.WFS separate of a vector layer in this case. I can imagine this is not the most common use case and I understand your concern about first getting the basics solid. I'll be looking into the whole Protocol.WFS stuff more next week (I started today), and hope I can come up with more testing and maybe some contributions. Thanks for all this great work btw! Best regards, Bart Tim Schaub wrote: Hey- [EMAIL PROTECTED] wrote: Hi list, the constructor of the new GML2 parser gets a featureType parameter. Does this mean that if a GML file contains multiple featureTypes, that I have to call read multiple times, and append the results myself? Will this be as efficient as doing the parsing in a single round? Yeah, this is because up until this point, vector formats have been used to read/write collections of features, and I think of collections of features as layers. I'd like to continue thinking that way (because I think it works). But I know there are people who are interested in making WFS requests for multiple feature types (which I like to think of as layers). I really want to get WFS working for the most common cases. And I want it to be solid (with good support for transactions and filtered queries). I've made a boatload of changes in the topp/wfs sandbox - including changes to the GML Filter code. My spare energy will be focussed on getting this code (the WFS protocol and related GML Filter changes) in to the trunk. Modifying the existing GML code is a bit at odds with that. I also know that it will make sense to have the protocol be used in the absence of a layer. And of course we want to support our OGC protocol power user(s). Bart, can you describe (perhaps again) where you want to make a single request for multiple feature types. I'm sure it is done all the time, I just usually see a way that I think it simpler, so I'm curious to hear more use cases.

What you can do is loop over your layers and then set

will have actually been drawn already.
Otherwise change the default WMS parameters of OpenLayers,

look. I have loaded the context in another viewer and the layers come

You can add a fake base layer with

var fake = new OpenLayers.Layer('fake', baseLayerOptions);
map.addLayer(fake);
map.addLayers(context.layers);
map.addControl(new OpenLayers.Control.LayerSwitcher());
map.zoomToMaxExtent();

Is there a way to make the layers transparent now that I have loaded them?
I think the problem is elsewhere but need some pointers on where to look. I
have loaded the context in another viewer and the layers come in as
expected.

Hi Joost,
you can pass layerOptions to the Format.WMC constructor in order to do
this. Code example:
mapfish.OGCUtil.readWMC = function(map, response, noZoom) {
var format = new OpenLayers.Format.WMC({layerOptions: {isBaseLayer:
false, singleTile: true, buffer: 0,ratio: 1}});
// remove all layers except the baselayer
for (var i = map.layers.length-1; i = 0; i--) {
if (!map.layers[i].isBaseLayer) {
map.removeLayer(map.layers[i], false);
}
}
map = format.read(response.responseText, {map: map});
...
}
Best regards,

Thanks John, that works. Now I need to know how to convert all of the
layers in my WMC to overlay's. Any ideas?

Is this possible? I want to add a fake base layer and load all the WMC
layers as overlays. Any ideas on how one would go about doing this?
You can add a fake base layer with
map.addLayer(new OpenLayers.Layer('None', {isBaseLayer: true}));

use something like:
isSuitableOverview: function() {return true;}
in your overview map constructor.
Example:
var overviewmap = new OpenLayers.Control.OverviewMap( {layers:
[overviewlayer], size: new OpenLayers.Size(225, 180), minRectSize: 10, div:
overviewdiv, isSuitableOverview: function() {return true;}, mapOptions:

Re: [OpenLayers-Users] Busy Cursor
Yes, it's not in the standard library, I am hoping it can be an addin soon.
See also the Wiki:
http://trac.openlayers.org/wiki/Addins/LoadingPanel
You can add the following in a script tag after the OpenLayers.js script
tag:
http://dev.openlayers.org/sandbox/bartvde/loadingpanel/lib/OpenLayers/Control/LoadingPanel.js
Or build your own OpenLayers.js. See also the Wiki page for details. You
also need to use a bit of css to get the background-image. It's described in
the Wiki page.

Hi Linda,
you could have a look at the LoadingPanel Control. Something similar could
be done to change the map cursor.
See:
http://trac.openlayers.org/ticket/102
and:

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

Re: [OpenLayers-Users] RC1 issue? with themes and styles
Hi Stephen,
you can also try using !important in the stylesheet you want to prevail,
so you don't need to change the css class names, example:
.olXXX {
width: 200px !important;
height: 200px !important;
}

(I downloaded broken.php, pointed the CSS to your files, and then

Christopher,
Thank you for taking a look at this. I will accept your good judgement
on this and try to dig into this a little more for my own education.
The one thing I noticed while poking at this in FireBug and Inspecting
the DOM, was that the missing icons had the CSS from the 2.6rc1
style.css while all the others had the CSS applied from my override CSS.
So by changing the CSS class to olControlMyEditingToolbar I seem to have
avoided that conflict. I guess I'm not sure how the CSS rules get
applied in this case when you have two stylesheets both with the same
class names.
Thank you again for your effort and assistance.

[OpenLayers-Users] mousewheel: center on point or not?
Hi list,
I thought the mousewheel used to center on the mouse cursor, but it does not
do this anymore in trunk. Or maybe my mind is playing tricks on me :-)
Questions:
-is this intentional?
-if so, could it not become a property of the Navigation Control so people
can control this behaviour themselves?
I commented the following in Navigation.js (deltaX * newRes etc.) to get it
to zoom centered on the mouse position again:
wheelChange: function(evt, deltaZ) {
var newZoom = this.map.getZoom() + deltaZ;
if (!this.map.isValidZoomLevel(newZoom)) {
return;
}
var size= this.map.getSize();
var deltaX = size.w/2 - evt.xy.x;
var deltaY = evt.xy.y - size.h/2;
var newRes = this.map.baseLayer.getResolutionForZoom(newZoom);
var zoomPoint = this.map.getLonLatFromPixel(evt.xy);
var newCenter = new OpenLayers.LonLat(
zoomPoint.lon /*+ deltaX * newRes*/,
zoomPoint.lat /*+ deltaY * newRes*/ );
this.map.setCenter( newCenter, newZoom );
},

this.style.strokeColor = blue;
this.style.fillColor = blue;
Any pointers?
Best regards,

Hi. What do you mean by the wfs layer is opaque? It means you don't
see the layers below the wfs layer ? Could you show us a screen shot
or something ? Thx. Eric
2008/2/6, David E. Reksten der at dod.no:
Just downloaded OL trunk for testing purposes. Built it with full.cfg,
but notice that my WFS layers are now opaque in IE7, rather than
semi-transparent as in FireFox2.
Have I missed a (build) setting, or is this a bug? If this is a
confirmed bug, I'd be happy to make an entry in Trac.
