Abstract

A Model to Generalize Hillshading
Track: Environmental Management
Authors: Patrick Kennelly

Detailed elevation data can be hillshaded in ArcGIS, but there are no tools designed specifically to create a generalized hillshaded map from detailed data. The model presented in this study uses a low-pass filter with a large kernel (15x15) to sum the surface normal vector, and then uses the vector-sum for a more generalized hillshading. The resulting hillshaded map appears smoothed without a blurry appearance.
