I have a simple question on the g.region module in Grass
GIS. How does it work when you change the resolution of the
current region? For example, I have with Landsat images with
a 30 m resolution, but I'm doing the analysis at a
resolution of 1 km. So are the pixel values aggregated in
some kind of way? Or is for instance only the value of the
middle cell selected? It might be a stupid question, but I
can't seem to find the answer anywhere.
see the "Resampling methods and interpolation methods" section of the
