I want to convert my DTM geotiff file from height above geoid to height above
ellipsoid.
I've tried the following command (among numerous similar commands):
gdalwarp -overwrite in_dem.tif out_dem.tif -s_srs EPSG:4326+5773 -t_srs
EPSG:4979
I have files|egm96_15.gtx| and|us_nga_egma96_15.tif| in my|/usr/share/proj|
resource directory, and|PROJ_LIB| is set to|/usr/share/proj|.
This transform works:
$gdaltransform -s_srs EPSG:4326+5773 -t_srs EPSG:4979
Enter X Y [Z [T]] values separated by space, and press Return.
10 20 0
10 20 26.504430770874
But the output file of|gdalwarp| is never different from the input file, no
matter what I try. Is it because the file is a DTM instead of a DEM?
Thanks!
