Hello,
I want to give census tracts categories values ( layer tenn_county_all)
based on there centroids location in a grid layer that I have made
(tenn_county_grid). The grid is nubered 1-42 and also as letters i.e.
row A colunm G.
I was planning to do something like
if centroid of tract X in grid box 12 write out category 12 for that
tract X.
I don't want to do this by hand but I am not sure how or if I can query
between two layers.
I am not attached to any particular method just need something that will
do the job.
I looked up info on the web and found bounding box in v.edit so I think
that is a way to go but have not seen anything on how to do this.
If your grid is vector, than v.distance should do the job.
