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.
No, there is not.
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.
Indeed it's not what you want, to sample random points I'd just use the
Coverage.evaluate method to pick values
at the various points, and then build a feature collection similarly to
RasterAsPointCollection, so that the
result can be encoded by the existing WPS as GML, JSON or whatever else
Cheers
Andrea
