This program writes a comma or space separated XYZ point file
from DEM files created by the

It only works on coordinate type dems. It doesn't work on dems based on arc seconds.
Open an arc based file with
3DEM
and change projection to UTM. Save file and try again.

This program reads comma separated point files.
It reads 2, 3 or 5(pxyzd) field point files and re-writes 2(xy) or 3(xyz) files.
You can swap XY fields and ignore the 1st line if your file has a header.
You can convert meters to feet, feet to meters or some other factor. If you're not concerned
about preserving the coordinates, you can reduce your point file size by moving all points to
minimum XY values of 1.
