Hi, I need help to analyze some data.
I have a shapefile with several attributes that correspond to polygons. Some of these polygons do not overlap, but others overlap.
The polygons have several overlapping case, for example:
- A polygon can exactly overlap other, or more than one.
- But it may happen that one polygon is overlapped by other polygon in a location and is overlapped by three polygons in another location and in other location it is not overlap by any polygon.
So what I want to do is an analysis of overlapping polygons, resulting an image where no overlapping polygons appear green, the polygon that has more than one overlay appear with different kinds of red. And, the polygon having different amounts of overlap would have different shades of red and green (in places where it had not overlap).
This has to be possible to do but I 'm having some difficulty. Can anyone help me on this problem? I have done several searches but I did not find the solution.
Thanks for your help .
