[GIS] Legends for WMS layer on Geoserver

geoserverlegendwms

Is there any way to get a representation of a WMS legend in a form that isn't an image? eg XML

Using an image for the website in our system will mean the text is not sharp, it doesn't resize with the web site, and the format of it is limited to what WMS provides.

Geoserver supports GetLegendGraphics in all the same formats than GetMap. For example http://demo.opengeo.org/geoserver/wfs?service=wms&version=1.3.0&request=getcapabilities seems to suppport also SVG which might suit well for you. Documentation at http://docs.geoserver.org/stable/en/user/services/wms/get_legend_graphic/legendgraphic.html is also worth reading.

If you read the WMS Spec you will see how to set the format of the error messages that the server sends you.

In this case it is clearly saying that the number 256: is invalid. Somewhere you are sending a request with that number in it, check the URL. For more information turn up the logging verbosity in GeoServer and it will send you back more details, or you could look in the log file to see what is going wrong there.

In WMS + SLD servers the closest operation to the ArcGIS API call is GetStyles.

A request would look like:

http://your/server/.../ows?
  service=WMS&
  VERSION=1.3.0&
  request=GetStyles&
  Layers=your-layer&
  sld_version=1.1.0&

Response is XML.
