For cases where sharing exact location information isn’t appropriate or isn’t needed, a solution is to

generalize EO polygons to standardized geographic units, such as quads, watersheds, Public Land Survey

sections, or square-mile hexagons (such as are used in the WAFWA Crucial Habitat Assessment Tool or

CHAT).

Below are screenshots with step-by-step instructions on using the free software Spatialite to do this. It

does what otherwise takes a lot of clicking in ArcMap or a lot of lines of code. In this example a filtered

set of EOs is generalized to townships (36 mi2).

Many thanks to Greg Krakow, Georgia Dept. of Natural Resources, for sharing information about the

sw and especially for giving a training session at BWB 2015. I’ve added in some text (pearls of wisdom)

he provided when he kindly reviewed this document. Any errors below are my own responsibility

however.
