[Users] WCS and GeoExt

[Bart van den Eijnden]

Hey Chris,

because of the difficulties you point out, there has never been any effort to parse something like WCS GetCapabilities, but it wouldn't be too hard.

The only WCS support that I ever wrote was a small piece of WCS GetCoverage XML to use in a WPS request (so this is write-only):

https://github.com/openlayers/openlayers/blob/master/lib/OpenLayers/Format/WCSGetCoverage.js

Start at the OpenLayers level with a parser for WCS GetCapabilities, and then add a GeoExt reader (if you need info about the actual coverages besides the service metadata) I would say.

If you need more guidance let me know.

Best regards,
Bart
