ArcScripts is intended for the free exchange of scripts and tools related to ESRI software products. Please alert the moderator if this script is a demo, trial-version, or an advertisement for a retail product.
This tool will calculate the area and diversity of selected attributes of a polygon layer at multiple user defined radial extents for each feature in a point layer. The output table contains the area of each selected attribute of the polygon layer at each buffered point feature as well as the selected diversity index values (Richness, Simpson's Index of Diversity, and Shannon's Diversity Index).
The zip file contains an installer and the documentation on the tool. The installer requires the Microsoft .Net Framework 2.0, the ArcGIS .Net Assemblies and runs on ArcGIS 9.2, Service Pack 6 or ArcGIS 9.3.
To install this tool in Vista, open a command line prompt as an administrator and use the command
msiexec /i "path-to-package.msi"
If there are no spaces in the path name, the quotes aren't necessary.
