Thanks lot for answer!
So I tried again the follows:
- edit and save ELEV_COLORS.dbf (import and export with MS Access) for my
color definitions
- load DEM and save the image - it looks really gray value for the whole DEM
- open the image with other program, and it is only one value (115, 115,
115)
I use "MicroDEM/TBII, ver14.29.13.3 August 2002" on my Windows -NT4.0
regards!
