An ArcGIS toolbox that calls Circuitscape directly from Arc. Requires ArcGIS 10.0 or newer.
A tool by Jeff Jenness that exports grids from ArcGIS to Circuitscape. Accepts raster grids and feature classes, and exports all with the same projection, cell size, and extent. This is useful if you are running ArcGIS 9.x and can't use the toolbox above.
