Hi All,
I am not able to understand the "unit" of the height (z value of the
point) of the data generated by VPB.
For example I have "DEM"  data which is in lat/long and i have generated
the height-field, each point
in the height-field has some finite value. What does this value
represents ? height in which unit (m , km ).

In the case of DEM data being in UTM coordinates I think the z value is
in "meters", but in case of lat/long
I am not able to understand the dimension. I tried converting
lat/long/height value to UTM using gdal. I am
able to convert lat/long to corresponding UTM x/y value but the height
value comes out to be same after
conversion.

Can anyone tell me how to do the conversion using gdal or with out gdal
to interpret the height data while
generating the height-field from DEM data in WGS84 lat/long.

Any help will be deeply appreciated.
best regards
Rahulj
