I am 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:
- what percent of that flight distance was through field?
- what percent of that flight distance was through forest?
- 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.
