New spatial reference systems have appeared for Switzerland and Austria, applied to hi-res LIDAR data. For our purposes the only difference is a different value range, which, unfortunately, TransDEM does not understand yet. Mathematically, it's a simple translation. So, I have written a little tool for XYZ data that converts the new systems to the old ones, adding or subtracting offsets.

The "user interface" is German only, but there are only three buttons and a drop-down list.

Ordner = Folder
Start = Start (Who would have guessed)
Abbrechen = Cancel

Example Canton Zurich (50 cm data, reduced to 1m), Ch1903+, converted to Ch1903:

Example Upper Austria (50 cm data, reduced to 1m), MGI 31 without false easting, converted to MGI 31 with a false easting of 450.000:
