The Estimation Tool for Impervious Surface (ETIS) allows to calculate the amount of imperviousness for specified area based on land cover and population density data. It was developed using linear regression equation and a set of coefficients based on the classes of the land cover map used. There are several sets of coefficients included with the Toolbox for Connecticut Land Cover (CCL) and National Land Cover Data (NLCD) 2001, but ETIS also allows to import custom sets and to demonstrate the effect of change in land cover on the amount of imperviousness. ETIS can estimate percent impervious cover for future land cover scenarios allowing for comparison to current conditions.
ETIS was developed as an ArcToolbox for ArcGIS 9.2 and ArcView 9.2 using Python Script, but can be used with ArcGIS 9.3.
It adds a new field to the Analysis Unit shapefile for PI values to be stored in.
