Terrain Sculptor: generalizing terrain models for relief shading


Leonowicz, A M; Jenny, B; Hurni, L (2010). Terrain Sculptor: generalizing terrain models for relief shading. Cartographic Perspectives, 67:51-60.

Abstract

Shaded relief derived from high-resolution terrain models often contains distracting terrain details that need to be removed for medium- and small- scale mapping. When standard raster filter operations are applied to digital terrain data, important ridge tops and valley edges are blurred, altering the characteristic shape of these features in the resulting shaded relief. This paper introduces Terrain Sculptor, a software application that prepares generalized terrain models for relief shading. The application uses a generalization methodology based on a succession of raster operations. Curvature coefficients detect and accentuate important relief features. Terrain Sculptor offers a graphical user interface to adjust the algorithm to various scales and terrain resolutions.
