[Gwt-openlayers-users] Producing clickable layers from WMS

[Philipp V. <ve...@go...>]

Hi,

I'm looking for a solution to make any wms layer clickable. That means that
there should be areas - which are bounded by a polygon - that show an
information bubble when hovering over.
Does anyone have experience in this field? As far as I know gwt-openlayers
does not support this feature.

I found a suitable example for openlayers using a WFS:
http://openlayers.org/dev/examples/getfeature-wfs.html

It is possible to add the needed funcionality and build the .jar by myself,
right?!

I'm thankful for any idea or comment on this.

Cheers,
Philipp

Hi Philipp,

I needed this kind of functionnality, but I didn't use WMS, just WFS.
The idea is to get your polygons from the WFS protocol, and load them into
your VectorLayer. If your polygons are static, you can even use GML files.
But I'm not sure that's what you're looking for, as this solution implies
the WMS is completely independant from the polygons.

Ask me if you want more info, I could even provide you with sample code if
you want.

Cheers,
Mikael

Re: [Gwt-openlayers-users] Producing clickable layers from WMS

[Lukas J. <luk...@de...>]

I will within a two weeks add this functionality to our app, (we're currently using WFS but need to handle larger amount of data which get impossible to load with WFS). 

The plan is to use the technique shown in http://openlayers.org/dev/examples/getfeatureinfo-popup.html to be able to produce popups for WMS-layers as well.

I'm not sure if gwt-ol implements all that I need to use, but if not, I will implement those parts myself and send them back as a patch.

Hi Lukas,

In the code in trunk there is a WMSGetFeatureInfo example, similar to
the example you reference. It uses a simple proxy included in the
latest GWT-OL from trunk.

With WMSGetFeatureInfo you have to be aware that there is no standard
for WMSGetFeatureInfo output. In GeoServer you can define templates
for this output, see here:
http://geoserver.org/display/GEOSDOC/GetFeatureInfo+templates

It would be great if you want to contribute enhancements back to GWT-OL.

Re: [Gwt-openlayers-users] Producing clickable layers from WMS

[Lukas J. <luk...@de...>]

Thanx I've totally missed that. I believed that I could request the data in a machine friendly format (for e.g. json). But it must be possible to create a template which will be easier to parse in my app code.

Thank you!

[Gwt-openlayers-users] Safari and multiple urls for a WMS baselayer

[Lukas J. <luk...@de...>]

I'm having a issue with Safari (4.0.5 on windows).
When I define a WMSlayer with a single url only it works fine, but when
initiate it with an array of url:s the urls: are combined into a string
where each url is separated with an ',' and this string is then used as
the url to the WMS server.

The constructor I call is:
WMS.java
public WMS(String name, String[] urls, WMSParams params, WMSOptions
layerParams) {
	this(WMSImpl.create(name, new JStringArray(urls).getJSObject(),
params.getJSObject(), layerParams.getJSObject()));
}

I've looked into JstringArray() and it simply copies all values from
urls to a JStringArray so no problem there.
In WMSImpl there is a comment about the Object/Array problem and this is
solved by once more copying the values from the new array, seems ok. The
new value is then passed to OpenLayers.Layer.WMS.

So the bottom line is that I have no idea why this works in all mayor
browsers except Safari. When I only use 1 url there is no problem. We
have another OpenLayers (plain OpenLayers, non-GWT) application which
also uses multiple url and that app does not show this symtoms.

Anyone got a clue?

Re: [Gwt-openlayers-users] Producing clickable layers from WMS

[Lukas J. <luk...@de...>]

Hello Edwin
I just completed my implementation with clickable wmslayers trough WmsGetFeatureInfo. I found that there exists a way to request the data in a machine friendly way (GML) by setting infoFormat to "application/vnd.ogc.gml". This means that I get VectorFeatures straight from the request and therefore can reuse my exists WFS popuprenderers to render popups. No need for HTML templating :)

While working with the implementation I added setDrilldown, setLayers and setUrls to WmsGetFeatureInfoOptions as well as getFeatures in the GetFeatureInfoListener class. These changes allow me to decide exactly what layers to query and they don't have to be served by the same server, which is the case when using using drilldown. 

I'm quite sure that drilldown and setLayers where added in OL 2.9, but I hope it's ok that I wrapped them as well.

I'd like some feedback on the methods handling arrays (setLayers and getFeatures) as this is my first time using wrapped arrays in gwt-ol. Is this the way to do it or are there any better patterns?

/Lukas

Re: [Gwt-openlayers-users] Producing clickable layers from WMS

[Edwin C. <com...@gm...>]

Hi Lukas,

Thanks for the patch! The way you are handling arrays seems fine. In
GWT 2 the options for working with arrays expanded, but the wrappers
are still relevant IMHO, and working well. This is an area that could
definitively use some documentation.

I see you are also using getPropertyAsArray(). This is a method I
still need to look at, because it can run into nasty runtime errors
that have to do with casting from JavascriptObject to Java Object. The
method seems useful, so I guess it needs to be reimplemented to guard
it against runtime exceptions.

Greetings,
Edwin

>> Hi Philipp,
>>
>> I needed this kind of functionnality, but I didn't use WMS, just WFS.
>> The idea is to get your polygons from the WFS protocol, and load them into
>> your VectorLayer. If your polygons are static, you can even use GML files.
>> But I'm not sure that's what you're looking for, as this solution implies
>> the WMS is completely independant from the polygons.
>>
>> Ask me if you want more info, I could even provide you with sample code if
>> you want.

>> Cheers,
