Hi Norman,
What should I specify as the source coordinate system?
-s_srs EPSG:4326
Or the convenient shorthand
-s_srs WGS84
Hmm, that doesn't seem to work either:
gdalwarp -s_srs WGS84 -t_srs "+proj=utm +zone=32 +datum=WGS84" 32V.tif
32V_warped.tif
Then I generate a terrain from that:
osgdem -d 32V_warped.tif --TERRAIN -v 0.0001 -l 8 -o database_osg/32V.osg
And if I load it, it's still the same as it was (i.e. too small relative
to other models modeled in meters).
gdalinfo output looks the same as before:
Driver: GTiff/GeoTIFF
Files: 32V_warped.tif
Size is 271, 241
Coordinate System is:
