Abstract

A flexible Python script tool for stratified random site selection
Track: Python for Analysis
Authors: Curtis Price

A stratified random, site-selection method used by the U.S. Geological Survey has been re-implemented as an ArcGIS geoprocessing tool. The method allows the user to select sites from an existing set of locations, or select new locations generated by a user-defined study area and point spacing. Although the method uses spatial grids, open-source Python (and NumPy) functionality has been applied to allow the tool to be supported under an ArcGIS basic license, with no extensions required.
