[Margherita Di Leo]

Hi!

simple test with r.volume. Small testing dataset here:

http://ubuntuone.com/2Odq6BDeQDdQhIJX2D8sHn

On Grass 6.4
r.volume --overwrite data=slope clump=basin centroids=centroid1

Cat    Average   Data   # Cells        Centroid             Total
Number  in clump  Total  in clump   Easting   Northing       Volume

    1      2.92    229610   78593   635195.00   220715.00      22961000.00
                                            Total Volume =    22961000.00

On Grass 7.0

r.volume --overwrite input=slope clump=basin centroids=centroid1

 Cat    Average   Data   # Cells        Centroid             Total
Number  in clump  Total  in clump   Easting   Northing       Volume
