What is BASINS 4?
We released BASINS 4 in April 2007. The latest update is available on this web site; no CDs are necessary. Also, no licensed or proprietary GIS software are required because BASINS 4 runs on OPEN-SOURCE GIS software (MapWindow ). BASINS 4.0 is based on a non-proprietary, open-source GIS foundation. By using open-source GIS tools and non-proprietary data formats, the core of BASINS becomes independent of any proprietary GIS platform while still accommodating users of several different GIS software platforms.
