I'm interested in calculating the overlap of home ranges (=utilization distributions in my case) of a bird species using sighting coordinates. This article introduced UDOI as the best index for such purpose:
I have ArcGIS 9.3, and I am able to calculate kernel home ranges using the ArcMap plug-in "Home Range Tools" (HRT). I also have "Hawth's Tools" in my ArcMap. Now I am hoping to find a way to calculate UDOI to demonstrate the degree of overlap between individuals.
I see that UDOI can be calculated in R, yet I do not know how to use R. Can someone tell me if there's any Arc tool that does this? Thanks a lot in advance!
I also see that the user "MTGIS" has asked this same question before:
And @whuber explained the math of UDOI in detail in the wonderful reply. However, I am not super familiar with ArcGIS, and did not understand how to do those steps in Arc. Sorry about repeating the same question! @whuber and anyone familiar with ArcGIS, would you mind walking me through the Arc function that does this?
