[GRASS-user] How to print a table with the values of a given raster layer aggregated by a second raster layer ?

[Antonello Lobianco]

Let's say in grass I have a raster layer "regionId" and a raster layer
"forestArea".

In the regionId I have stored the ids of the regions, in the forestArea I
stored the square km of forest within the pixel.

How can I print a table summing up the forest area by region, that is the
sum of the values of a layer aggregated ("group by") by a second layer ?


Cheers,

  Antonello
