A WMS GetCapabilities request will return a document listing all available layers if you've configured your mapfile for WMS. With a typical GetCapabilites request, you can't ask the server to limit what it responds with (only layers in a provided bounding box). The client is forced to deal with the full capabilities doc, but you can do the filtering after parsing. The OpenLayers.Format.WMSCapabilities parser can be of use in parsing capabilities docs. > If it matters, we do store the extent of each layer in the mapserver map > config file. > > The end game is to be able to build a legend for layers that are on the map. > Any ideas? > A WMS GetLegendGraphic request will return a server generated legend.
