Hi Vijeesh,
osgdem will assume the coordinate systems of the input if your don't
provide any guidance on the output format. I you run 'osgdem -h' in
the console the command line options will be listed, these include:
--geocentric Build a database in geocentric (i.e. whole earth) database.
and:
--wkt <WKT string>
Set the coordinates system of source imagery, DEM or
destination database in WellKnownText form.
--wkt-file <WKT file>
Set the coordinates system of source imagery, DEM or
destination database by as file containing WellKownText
definition.
In the case of the --wkt usage, you'll want to place this before the
-o, but after the -d and -t entries otherwise you'll override their
coordinate systems. The WellKnownText format is passed onto the GDAL
to do the reprojection, and it's syntax is written up on GDAL website.
