Build RELATIVE Digital Elevation Models

(currently only .BIL-Files)

For all values Z(x,y) in a DEM the following filter rule is applied:

1. Calculating the mean Elevation Z_mean(x,y)
within a Radius R

2. Z_relative(x,y) = Z(x,y) – Z_mean(x,y)

Radius R:

The radius influences the position of  the local extreme values. Good results can be achieved by using the average [...]
