Hi Robert and Jason,

yes, there are different coordinate systems:

texture - lat/long
height - UTM 32N  (WGS 84, meter)

At the time I care about the "optical aspect" only thus I didn't test
which coordinate system the output had.
Unfortunately I can't send images since the data is not ours. I will
do some testing with the Puget Sound data.

Cheers, have a nice week
Christoph
