| [udig-devel] Single UDig Layer with Multipe WMS Layers |
|
Hi, Is it possible to fetch multiple WMS layers merged into a
single IGeoResource? I have UDig connected to a WMS server on Geotools. I
construct my layers by first adding the WMS server to the catalog and then
using ICatalog.getById() to retrieve layers from the WMS server. This
works well for adding IGeoResources to my map one at a time. I would like
to fetch multiple layers in a single request so that Geoserver can do all of
the work involved in merging multiple WMS images into a single image. For
example, with openMap I can use http://localhost:8080/geoserver/wms?&request=GetMap&layers=tiger:poly_landmarks,tiger:tiger_roads
to retrieve multiple layers with a single request, so that openMap only receives
a single image representing both layers; all of the calculations involving
features and combining the two layers into a single image are performed by the
non-client computer hosting Geoserver. I would like to do something
similar with UDig while interacting with the catalog containing my WMS. Is this possible? Thanks in advance, Joe |
