Hello,
I'm wondering if there is a command that is similar to the euclidean
allocation tool in ArcMap (similar to voronoi polygons in vector
analysis)? I would like to calculate new cell values based on one raster
with the shortest distance from the nearest input feature in another raster.
IIUC how euclidean allocation works, isn't this "just" r.grow.distance
with the 'value' option ? I.e. (in the NC demo dataset):
g.region vect=schools_wake res=100 -a -p
v.to.rast schools_wake out=schools use=cat
r.grow.distance schools value=school_basin
