Welcome to the Circuitscape Project!
Circuitscape is a free, open-source software package that borrows algorithms from electronic circuit theory to predict connectivity in heterogeneous landscapes. See the tabs above for more about Circuitscape, downloads, and other connectivity modeling tools and resources.
March 2014- Circuitscape 4.0 is now up! After a complete overhaul, Version 4.0 sports major speed and functionality improvements.
March 2014- Need to create resistance or core area layers? Check out the new Gnarly Landscape Utilities.
Oct 2013- Circuitscape can now be called from an ArcGIS toolbox. No more converting input grids to ASCII format! Just install the ArcGIS toolbox from our downloads page when you install Circuitscape.
Jan 2013- Linkage Mapper is now integrated with Circuitscape. It uses Circuitscape to identify pinch points within least-cost corridors and to analyze linkage network centrality. See the Linkage Mapper website for more.
Circuitscape was written by Brad McRae, Viral Shah, and Tanmay Mohapatra. More details about the authors here.
We are especially grateful to the Wilburforce Foundation for funding Circuitscape 4.0 and the original version of Circuitscape. The Cougar Fund also contributed to the original development. We also wish to thank the Washington Program of The Nature Conservancy and the National Center for Ecological Analysis and Synthesis for supporting Brad McRae and the University of California, Santa Barbara for supporting Viral Shah while they collaborated on the project.
