[gdal-dev] Converting USGSDEM into GTOP30 DEM or DTED

I don't believe this is possible. I think the DTED specification states
a single dted file must be of fixed pixel dimensions: 1201x1201
(2402x1201 north/south of 70°). Certainly thats the case for CDED which
was derived from DTED.

best regards,
