"Height files have the extension .HGT and are signed two byte integers.
bytes are in Motorola "big-endian" order with the most significant byte

may be necessary. Heights are in meters referenced to the WGS84 geoid.

Subject: [Gdal-dev] how to read SRTM files
I'm downloading SRTM NASA ziped files from=20

know this file format(.hgt)
runnig "gdalinfo" one .hgt file I only got:
ERROR 4: `N01W050.hgt' not recognised as a supported file format.
GDALOpen failed - 4
`N01W050.hgt' not recognised as a supported file format.
Or my GDAL tools is missing something?
