  1. Estimation Tool for Impervious Surfaces (ETIS) Anna Chabaeva Jason Parent Daniel Civco Department of Natural Resources Management & Engineering The University of Connecticut U-4087, Room 308, 1376 Storrs Road Storrs, CT 06269-4087

  2. Comparepredicted amount of imperviousness to: • highly accurate and precise planimetric data • NLCD 2001 impervious surface layer • CCL 2002 impervious surface layer • ISAT derived impervious surface data (NLCD, CCL) Objectives Describe functionality of newly developed ETIS tool

  3. Rooftops Transportation System • Roads • Sidewalks • Driveways • Parking lots • Buildings • Pools • Patios Impervious Surface (IS) The imprint of land development on the landscape:

  5. Validation Data 82 CT tracts Calibration Data 221 NY tracts ETIS – Regression Model where - b1 is the IS-axis intercept - b2 is the coefficient for population density - biare those for percentage of land cover category area within the tract - PopDen is the Population density - %Ai are the percent of the land cover category area within the tract
