If I load the original .csv file, I then have a map of the African continent represented by 14069 data points covering it at 40x40km resolution. Each data point shows solar radiation means across the year, (jan, feb, etc).
What I want to be able to do is convert that vector into a raster using GRASS.
What I have managed to do already, is import the .csv (tab delimited) file into the GRASS mapset using v.in.ascii. However, when I try use v.to.rast.constant to convert that vector into a raster, I get a solid square covering Africa, that cannot be edited. I.e. there is no data from the vector within the created raster.
What am I doing wrong?
This work is for my masters thesis and I'm constantly working on it.
