Hi all,

Please excuse this question from a GIS novice. I have loaded 3 shapefiles into my GIS; one is a polygon file representing various forest classes (A), the other (B) is a point file with 119 points,and the 3rd (C) is a single point location. For each of the 119 points in B I would like to generate 1000 random points that are the same distance from C. Then I would like to know the forest class polygon in A that each of the resulting 119,000 points falls within.

If someone could suggest a solution I'd be most grateful. Thanks.

Hi Bill. You're right, I basically want to know the proportion of each forest class at the same distance from point C, for each of the 119 points in B. The 119 points are locations of bird sightings and point C is a release location, and I want to know whether the habitat they were in was proportional to what was available, given the distance the birds were from the release site.

Is there an easier way of doing this that creating random points?

Thanks for any help you can give here.
