[GRASS-user] change resolution using g.region

[Silvia Simoni]

Dear grass users,

does anyone know which is the algorithm applied to a raster map when  
changing the resolution using g.region res=XXX?
If I have a 1m resolution raster map and I change the region  
resolution to 2m using g.region, the new 2x2-cell values are an  
average of 4 cells in the 1x1-map?

thanks,
silvia
