[Geoserver-users] WPS: Sampling rasters at point locations

Hello,
I am interested in developing a WPS that will accept as input a collection of points which would be used to sample a raster (or a number of rasters) and return the resulting values back to the client.
Before delving into this I wanted to see if there was a service such as this already packaged with geoserver. I’ve scanned through the list in the WPS request builder and stumbled across the ras:RasterAsPointCollection process but I don’t think this is exactly what I’m looking for. If anyone knows if there is an existing implementation of this service please let me know.

Thanks,
Rod.
