I have rasters covering certain spots in my environment, I'm looking for a way to extract the values which occur at locations which are defined by a selection of feature layers. I've tried with the SelectLayerbyLocation tool (from ArcMap 10.2 (advanced license)), which seems to do the right thing, but not for this type of data. Does anybody have experience with this or recommendations for tools to use?
Currently it is set up like this:
arcpy.SelectLayerByLocation_manager('codist_{0}'.format(FIDa), "INTERSECT", out_flab).save(overlap) #find out if villages overlap with cost layerswhere 'codist_{0}'.format(FIDa) is the raster (FIDa a list of values), and out_flab is the feature layer extracted from a table using a cursor in previous steps. Ultimately I need to find the minimum value within the rasters at the zones defined by the feature classe (so the values of the raster cannot be altered by this operation)
