Pyramid Shader

Pyramid Shader is a specialized application for visualizing terrain models and other digital raster data.

Pyramid shader can create:
  • Shaded relief
  • Illuminated and shadowed contour lines (“Tanaka contours”)
  • Hypsometric colors
  • Local hypsometric colors
  • Exposition colors
  • Bivariate colors
  • Slope
  • Aspect
  • Profile curvature
Pyramid Shader can generalize terrain by removing small high-frequency details and/or large landforms.
