This C library supports TIFF 6.0 based interchange format for georeferenced raster imagery. The GeoTIFF standard has been developed for reading, and writing geographic meta-information tags on top of TIFF raster.
The GeoTIFF library comes with two utility programs here included:
listgeo - dumps the metadata of a GeoTIFF file.
geotifcp - applies metadata to a TIFF file, making it a GeoTIFF file.
