Re: [Geotools-gt2-users] extract data from a wms layer

[jv <cib...@gm...>]

WMS has three type of queries (capabilities, maps, features). The
first one gives you the list of avalaible maps. The second one, a
*raster* image. And the third one can be used to obtain additional
information.

As you can see, the underalying protocol defines this way of interaction.
