[GRASSLIST:4492] aggregate a higher resolution to a lower resolution

[Ulrich Leopold]

Dear list,

I would like to aggregate my map from a 250x250m resolution to a 500x500m 
resolution. If I use resample the nearest neighbor is used. Is there a 
possibility to just average 4 250x250m blocks (like overlay a grid and 
average) instead of nearest neigbor? So that I derive a mean and a variance?

Ulrich
