[OpenLayers-Users] created a new SR-ORG id on spatialreference.org but now need to revise the definition
Hi All, I created a new SR-ORG id on spatialreference.org (http://www.spatialreference.org/ref/sr-org/6728/proj4js/) but now, I need to revise some of its definition (proj4js's +lat_ts=90 needs to be +lat_ts=60 ). Also, must one absolutely go through the WKT definition to define the SR-ORG id? Is it possible to define the SR-ORG id strictly from a proj4js definition? SP. Stephane Poirier, M.Sc.

I had a similar problem and was using pgRouting. The way I solved it was
to have my Ajax server the gets the results from pgRouting do some
additional checking and flip the segments so they are all in the same
direction along the path. Basically, the segments are returned in the
order of first to last, but because you might traverse a segment in the
opposite direction than that which it is stored in the database you get
the segment in reverse order. Your segments are all stored with A as the
start and B as the end. Then you might get results back like:
1 2 3 4 5 6
AB,AB,BA,AB,BA,BA,etc
So you have to first see if the first segment needs to be flipped:
if 1A == 2A or 1A == 2B then flip first segment,
for i=2 through N {
if (i-1)B == iB then flip segment i
}
now all the segments should be in the correct end to end order. and you
can just chain them all together.
I'm sure you can do the same in Javascript.

Re: [OpenLayers-Users] Create feature from sketch by imitating a bouble-click event
Hi Amit,
why don't you just use a DrawFeature control with a Path handler on a
vector layer and listen to the layer's sketchmodified event, checking
for feature.geometry.components.length?
var layer = new OpenLayers.Layer.Vector("result");
var control = new OpenLayers.Control.DrawFeature(layer,
OpenLayers.Handler.Path);
layer.events.on({
sketchmodified: function(evt) {
if(evt.feature.geometry.component.length == 2) {
control.handler.finalize();
}
}
);
You will then have the feature on your layer. Nothing else to do.
Regards,
Andreas.

Hey Bill- thanks for your efforts on cursors documentation. You could provide a user example (in http://openlayers.org/dev/examples/) and link to it from the wiki. To do so, please create a ticket and provide a patch (see http://trac.openlayers.org/wiki/HowToContribute). Another option would be to create a ticket and patch against http://svn.openlayers.org/trunk/doc/, which is the file structure that creates http://docs.openlayers.org. Unfortunately this would require to convert the wiki content that you already created to rst. Let me know if you have more questions or need further assistance. Regards, Andreas.

[OpenLayers-Users] WMSGetFeatureInfo doesnt seem to work
Hi guys,
Currently I try to find my way in to OpenLayers.
The problem, I'm currently facing, is that this code:
function load () {
var map = new OpenLayers.Map('map');
var wms = new OpenLayers.Layer.WMS(
"OpenLayers WMS", "http://labs.metacarta.com/wms/vmap0";,
{
layers: 'basic',
//srs: 'EPSG:31467',
format: 'image/gif'
}
);
var studiwohn = new OpenLayers.Layer.WMS(
"Studentenwohnheime ", "http://localhost:8080/geoserver/wms";,
{
layers: 'topp:Studentenwohnheime',
//srs: 'EPSG:31467',
transparent: 'true',
format: 'image/gif'
}
);
map.addLayers([wms, studiwohn]);
map.zoomToMaxExtent();
var info = new OpenLayers.Control.WMSGetFeatureInfo({ url:
'http://localhost:8080/geoserver/wms', title: 'Identify features by
clicking',
queryVisible: true,
eventListeners: {
getfeatureinfo: function(event) {
map.addPopup(new OpenLayers.Popup.FramedCloud(
"chicken", map.getLonLatFromPixel(event.xy),
null,
event.text,
null,
true
));
}
}
});
map.addControl(info);
info.activate();
map.addControl(new OpenLayers.Control.LayerSwitcher());
}
doesn't work very well, when I click on one of my features in the Layer
"Studentenwohnheime", i can see that a query is submitted to the server, but
no result is being sent back.
Kind regards,
Dominik

[OpenLayers-Users] IE7 vector rendering error
Dear All, I am using revision 9635 of openlayers (via the MapFish svn), and have just created a single file library for openlayers to speed up this page: http://mapdata.thehumanjourney.net/vgswandb_new.html In IE7 (either using IETab or genuinely using IE7) I get the error "Your browser does not support vector rendering. Currently supported renderers are: SVG VML Canvas". This error occurs when the page is originally loaded, and when you try and select a feature (by dragging a box around it), nothing happens instead of it being highlighted and showing feature information as it is supposed to. Previously I have had this error when trying to use the library.cfg file to create my single file library, and I fixed it by adding lots of additional includes, but this time I went for the full.cfg file instead, and still have the error. A search of the mailing lists suggests this problem used to occur in earlier releases, but should now be fixed. I have tested this page with the original multi-file version of OpenLayers and it does not occur.

Re: [OpenLayers-Users] How to call a function that sets attributes for features added by drawfeature-control
Hi Max,
I'm not sure about what could be the best approach. My guess would be
to define a stylemap with your default 'default' and 'select' styles for
newly added features, then when your user choose a color for the
feature, add a rule based on the feature id.
Have you checked : http://trac.openlayers.org/wiki/Styles ? It could
helps to learn more about this.
Also, an example with unique rules :

Re: [OpenLayers-Users] How to call a function that sets attributes for features added by drawfeature-control
Hi Alexandre,
I got it working now. The Problem was that in the function that was
triggered by the featureadded-event I tried something like feature.id and
not evt.feature.id.
I registered the event via
"drawFeatureControlName.events.register("featureadded", ' ' , function)".
But, as always, one problem solved and another one evolves. As said before I
want to apply a user-customizable style to each feature added. I´ve done
this for example via "evt.feature.style = {fillcolor: "#FF9933",
pointRadius: 10, strokeColor: 'black'}" and after that I´m redrawing the
feature via "vectorLayer.drawFeature(evt.feature)". This works and the point
is symbolized in the planned way. But when I select one of those points on
the map the radius shrinks (I guess to the size of the default-style for
point-Vectorfeatures) and the stroke is gone. Even when I unselect the
feature it stays in this changed style. Now I tried to apply a stylemap with
default- and selectStyle to the feature but that didn´t have any effect (the
points stayed in their default-orange-style).
Any idea how to solve this problem? Rulebased styling via a layerwide
stylemap is no option cause as said above the user should be able to choose
color etc. independently.
Greets and thx for your help

Re: [OpenLayers-Users] How to replace country color with image ?
Jerome,
I don't know anything about your application and the infrastructure
that you are running it on. If you are using MapServer to serve WMS
or WFS layers to your OpenLayers app, I have a different approach that
could work for you.
Instead of using an OpenLayers vector layer, you could use a WMS
layer, where the styling is done on the server. MapServer can use an
image to color the fill of a polygon.
There are examples here (near the bottom of the document):

Re: [OpenLayers-Users] Style WFS layer by attributes
Try to apply a stylemap to your vector layer.
// Creation of a stylemap
myStyles = new OpenLayers.StyleMap({
"default": new OpenLayers.Style({
strokeColor: "${getFillColor}",
fillColor: "${getFillColor}",
strokeWidth: 2,
strokeOpacity: 1,
fillOpacity: 0.7,
pointRadius: 5
},{
context: {
getFillColor:function(feature) {
if (feature.attributes.state == true)
return '#00FF00';
else if (feature.attributes.state == false)
return '#FF';
}
}
})
,"select": new OpenLayers.Style({
fillColor: "#0FF",
strokeColor: "#FF",
pointRadius: 6
}),
"hover": new OpenLayers.Style({
fillColor: "#CC",
strokeColor: "#99",
pointRadius: 6
})
});
// Create a vector layer and give it your style map.
var points = new OpenLayers.Layer.Vector(
'Points', {styleMap: myStyles}
);
if you still have problems, please send you script, i'll try to debug

Re: [OpenLayers-Users] Style WFS layer by attributes
Hi Jerome,
probably I don't understood exactly how to apply your suggestion...
If I use "new OpenLayers.Style" I can't apply any style to my features.
The only way to style them appear to be:
OpenLayers.Util.extend({}, OpenLayers.Feature.Vector.style['default'])
So I need to do something like
//Vector layer style
var area_style = OpenLayers.Util.extend({},
OpenLayers.Feature.Vector.style['default']);
if (feature.attributes.myattribute == 'myvalue') {
area_style.strokeWidth = 1.5;
area_style.strokeColor = "#ff";
area_style.fillOpacity = 0.75;
} else {
...
}
but it does not work (feature is undefined)...

Re: [OpenLayers-Users] How to call a function that sets attributes for features added by drawfeature-control
Hi Max,
Here's an old demo that could help you for some of your needs :
http://dev4.mapgears.com/bdga/bdgaWFS-T.html
Simply click on a feature. This demonstrate a way to edit feature's
attributes in a form. If your data is stored in a DB, you don't need to
take care of the id manually. The DB will automatically generate one.
The example is using WFS-T to TinyOWS connected to a PostGIS DB.
Best of luck,
Alexandre

Re: [OpenLayers-Users] Style WFS layer by attributes
Hi Alessio,
You can define a style and, depending a context, assign different value.
Here is an example that change the fillcolor of feature depending on the
attribute "state" of each feature.
Note that the context is automatically applied to features. Nothing to
activate ;)
new OpenLayers.Style({
strokeColor: "${getFillColor}",
fillColor: "${getFillColor}",
strokeWidth: 2,
strokeOpacity: 1,
fillOpacity: 0.7,
pointRadius: 5
},{
context: {
getFillColor:function(feature) {
// Green if state is true
if (feature.attributes.state == true)
return '#00FF00';
// Red if state is false
else if (feature.attributes.state == false)
return '#FF';
}
}
})

[OpenLayers-Users] How to call a function that sets attributes for features added by drawfeature-control
Hi list,
I´m actually implementing a drawfeature-control for my web-GIS. Everything´s
working fine so far but now I want to add a little more functionality:
- the user should be able to specify the appearance of the features he´s
adding. This shall only have an effect on the features he´s adding after
specifying the style (so a change of the general vectorlayer-Style is not
useful)
- each feature should get a unique ID whose format I´d like to specify and
which is generated by a script-wide counter for example
For both of this cases I thought of the event featureadded. But I´m having
some trouble with it. Here´s what I tried:
1. event-listener on the layer to which the features are added:
example: vectorLayer.events.register('featureadded', vectorlayer,
testFunction);
2. event-listener on the handler for drawfeature-control (same as above but
with vectorLayer being replaced by the drawfeature-control)
3. event-listener in this form:
vectorLayer.events.on("featureadded": testFunction, ...);
The testFunction is meant to specify the attributes like style, id etc. on
the feature that was added. The function is executed (tested it with an
alert).
The problem is that it´s not possible to select features on this layer (the
other vectorlayers are still working) when using the featureadded-listener.
But I need to be able to select features to modify it´s attributes later on
or to clear them via a form.
I also thought of using the create-callback of the point-handler but don´t
know how to implement it.
Any ideas and help is appreciated.
Thx in advance
Max Stephan

[OpenLayers-Users] Style WFS layer by attributes
Hi,
I have this WFS layer from my UMN-Mapserver
//Vector layer style
var area_style = OpenLayers.Util.extend({},
OpenLayers.Feature.Vector.style['default']);
area_style.strokeWidth = 1.5;
area_style.strokeColor = "#ff";
area_style.fillOpacity = 0.75;
//Layer definition
qAreas = new OpenLayers.Layer.Vector("WFS",
{
strategies: [new OpenLayers.Strategy.BBOX()],
filter: propertyFilter,
style:area_style,
protocol: new OpenLayers.Protocol.WFS({
url: wfsURL,
extractAttributes:true,
featureType: "QueryAreas",
geometryName:"the_geom"
})
});
I'd like to use an attribute value to style things differently
(for example, if the value of the attribute named type is "A" the
corresponding polygons bacame red and if it is "B" they became blue)
Can you help me? :-)

[OpenLayers-Users] File KML generated does not contains any style information
Hi all,
I'm trying to export kml using 'write' function. The kml file is generated but
it doesn't contains any style information (color, image etc.) and it's
represented on Google Earth as a white line.
How can I put the style information in the file?
Here is just a part of my code:
var gml3 = new OpenLayers.Format.GML.v2(gmlOptionsIn4);
var provaLayerFeatures = new OpenLayers.Layer.Vector("provaLayerFeatures", {
isBaseLayer: false
});
featuresExpKml = gml3.read(unescape(g.geometry));
