Hi and thanks for the help in advance.

I was wondering if there was a way/what the proper way is to perform various spatial analyses per county (polygon). I would like to analyze a species occurrence in a county to raster data such as precipitation, soil, temperature...etc. The problem is that I only have the presence absence data at the county level (IE I have no points, only polygons denoting if the species is present(1) or absent (0) in that particular county (polygon.)

Could I just find the averages of each raster dataset for each county (polygon)?

I have a feeling that my occurrence data is too coarse for this....

I am using ArcGIS 10.1 on Win7 x64 machine.

Thanks again!
