I've got a DEM, basically a cut-out of SRTM data. Trying to calculate its
slope gives me extremely weird output, such that all values are 89 degrees.
Dataset: http://linfiniti.com/~rudi/SRTM.zip
Can anyone confirm? I'm suspecting a local issue though, not the data ...
You're SRTM has geographical CRS (WGS84). You must keep into account when
doing morphological analysis. If you reproject it to a planar projections
(e.g. UTM) the results are correct.

Hi Rudi
From Version 1.8 on, you can set the parameter 'z-scale' if your x-/y-
units are different than the z-unit.
If e.g. x-/y- is degrees and z meters, you may set z-Factor 20.
