Is there anyway to detect a self-overlapping poygon (i.e. single polygon of ID x overlaps with single polygon of ID x). This is sometimes a problem when importing features from a GPS unit, but these overlaps are not detected wit the topology tools. Thanks!

Thanks DrColgate! This worked. I think I was hitting Apply and then OK, which was probably why it was failing. I'm unsure now, bit clicking OK immediately after updating and saving, seemed to do the quick.

I have attempted to update the Tool Validator (ArcGIS 10.0) code as per the instructions within the Help file. However, it is not behaving as expected. When I choose the option to "Edit" on the Validation tab of the Properties dialog, IDLE will open with a file called "xxScript.py", which is created in a temp folder under my user profile. I made changes in this file and saved (as per the ESRI Instructions), but when I apply the changes I get nothing. And when attempting to edit it again, it simple created a new copy called "xxScript2.py", which was a copy of the original. Is there a place/naming convention I should be saving this file after modifying so that it can be referenced?

I've just recently been trying to solve a similar problem. Take a look at this document for some help: http://www.esri.com/library/whitepapers/pdfs/lidar-analysis-forestry.pdf Also, if you are using ArcGIS 10, I found a section for "Estimating Forest Canopy and Height", so if you try a search there, you might have luck.
