Hi all,

A question about ossim Landsat support :

It seems like some Landsat file formats are not supported by ossim.
Reading the code (ossimLandsatTileSource), I understand that it supports only the FAST format, and not the GeoTIFF products shipped with a MET or MTL metadata file.

Can you confirm ?
If yes, did someone start working on an image handler supporting those Landsat files ?

Our need is to have the calibration coefficients in a keywordlist (no need for the sensor model).

On the basis of an IRC discussion, it seems the right place where managing
those formats is ossim, which currently lacks some widely used Landsat formats
(geotiff + MET/MTL files). Just for note, a very simple meta information
reader is currently available in i.landsat.toar Grass add-on module.
