[gdal-dev] GDAL Question about the band/frequence information

[Frank Warmerdam]

Shuqing,

GDAL does not have a well defined name for metadata describing a bands
wavelength.  Some data products carry this in their metadata and it
may be carried through via the GDAL generic metadata at either the
band or dataset level.  Running gdalinfo against a file will show such
generic metadata if it exists.  If not, you are out of luck.  :-(  In
any event since there is no consistent approach to this you are going
to be stuck doing product specific things, likely based on researching
the each sensor yourself.

Best regards,
Frank
