Terrain Generalization

We develop interactive methods for generalizing elevation models that allow the user to selectively remove superfluous details and enhance important terrain features.

Terrain Sculptor is an application for the generalization of terrain models for relief shading. It removes irrelevant details and accentuates important features.

Terrain Equalizer is an application for frequency filtering of terrain models. Terrain detail can be adjusted with the viewing distance.
