I'm using ArcMap 10.1. I had an orthophoto of an old study site. I traced two polygon shapefiles from this photo- one of "fields" and one of "forest". I made a point shapefile of the sampling points, and a polyline shapefile of all possible paths between the sample points. If a butterfly were to fly from one sample point to another (assuming linear flight along the polylines), I am looking to determine; a) what percent of that flight distance was through field, b) what percent of that flight distance was through forest and c) how many times that individual had to cross a forest/field edge.
I haven't used GIS since my intro class many years ago, and I can't even figure out the correct vocabulary to search for the answer myself. Any and all help is greatly appreciated! Even if you don't know how to do this, suggestions of what to search for are equally appreciated!
