Does anyone know an answer to the following: I have a set of polygons created as the MCP of animal movements. I also have a habitat colour map raster, with 13 different habitat types as different colours. I need to find a way of overlaying one on the other and calculating the area of each habitat type within each polygon. Possible? I think it has something to do with overlaying, but have not used it before, and usually asking those who know is far faster than self-discovery! Thanks in advance.
