Impervious Surface Analysis Tool – Help

---

This ArcView^® tool was developed to help managers and planners use remotely sensed data to determine total impervious area and percent impervious area within specified polygons. It is an extension for ArcView version 3.x that applies impervious surface coefficients to land cover data in a grid theme. The purpose of the tool is to help managers make a determination about the impact impervious surface coverage has on the local water quality.
