Impervious Surface Analysis Tool  (ISAT)

The Impervious Surface Analysis Tool (ISAT) is a free decision support tool designed to calculate the percent area of a watershed that is covered by impervious surfaces.  ISAT is simple to use and helps water resource and land use planners and managers assess existing water quality conditions.  ISAT was developed through a collaboration between the Geospatial Technology Program in the University of Connecticut's Center for Land Use Education and Research and the NOAA Coastal Services Center.
