I have two shapefiles, both polygons.
1) The first file represents the administrative boundaries of provinces. This file contains a lot of fields. [social, geographic, natural, morphological etc] 2) The second file represents the cover of a specific type of tree. This shapefile contains some fields [the type of tree, surface area etc.]
What I want is to get the sum of the total surface area of all tree cover within a state.
I have tried multiple ways and read multiple posts, but none quite seem to do what I want to do...
I feel this is a relatively simple question. I thought I could do it with field calculator. But field calculator doesn't allow for the selection of multiple shapefiles...which I find very strange.
