This library is designed to permit the extraction and parsing of the "GeoTIFF" Key directories, as well as definition and installation of GeoTIFF keys in new files. More information about GeoTIFF specifications, projection codes and use can be found here. Information on the mailing list and archived SVN repository can be found here
Archived releases can be found on the GitHub releases page or the OSGeo archive page

libgeotiff should work with the Visual Studio toolchain. See .appveyor.yml for example.

There are two demonstration test programs
listgeo that create and list-out the GeoTIFF tags and keys associated with a small TIFF file, as well as a full-featured utility called
geotifcp. These will all be built in the
bin/ directory as a matter of course, though may require modification if you are not using
LibTIFF, as they make explicit calls to
LibTIFF for opening the files and setting the tags.
To run them simply call:
to generate and list an example GeoTIFF file. To see the
geotifcp utility in action, first call:
listgeo newgeo.tif > metadata.txt
to create a GeoTIFF metadata file
metadata.txt, and then
geotifcp -g metadata.txt newgeo.tif newer.tif
to copy the TIFF file
newer.tif, using the GeoTIFF metadata as stored in
docs/manual.txt for further uses of geotifcp.
To convert a projection metafile, an ESRI world file, and a raw TIFF file into a GeoTIFF file do something like the following:
tiffcp -g metadata.txt -e abc.tfw abc.tif geo_abc.tif
This library was originally written by Niles Ritter (also the primary author of the GeoTIFF specification).
