Hi Roberto,
The solution Dan has suggest would be one way to do it but the best solution
and something I will add to my list of things to do would be for the spdmetrics
command to take a thematic image of raster clumps alongside the shapefile and
for the calculated metrics to be added added to the attribute table of the
raster rather than the shapefile.
You could effectively hack this by calculating the metrics onto the attribute
table of the shapefile and then writing some python to copy the attributes to
the raster clump file. This would effectively be how I would implement this
functionality with the spdmetrics command, just without ever writing anything
to the shapefile so the results would be the same.
Hope that makes sense.
Cheers, Pete
