Dear lists:
I have seen some discussion of my topic but nothing to fully satisfy my needs.
Am wondering if anyone has script, etc. that will do more than the ArcView
intersection of polygon tool that just gives the number of intersecting objects
for each polygon with one summary statistic.
My issue is, if I have two shape files (e.g. A, B) I want to know how many
objects in file B intersect each object in file A, and their corresponding
proportions, such as for polygon A1, (B1, B2, B3) intersect it with B1
contributing 20% of itself, B2 contributing 25% of itself, B3 contributing 30%
of itself, etc.
Hopefully this makes sense. Suggestions for creating this would be helpful if
no one has done this but I am not well-versed in the ArcObjects
model.
