Data Preperation

Contains algorithm which help in preperation of a DEM before starting any Terrain analsysis. For example for the SRTM DEM in most of the cases a low pass filter appears to be quite appropiate. In cases where watersheds are needed, differnet sink filling routines are recommended, however this will influence some of the other results.

  2. convert
  3. filter
  4. outlier
  5. scale
  6. transform
