GDAL
Installation
Best install using standard system package manager, such as apt-get (Ubuntu), yum (Fedora), or macports (OSX).
Download of source code
The current download page is from http://download.osgeo.org/gdal/. However, web searches lead to dead links or irrelevant redirects.
Documentation
- Some apparently legacy documentation is at https://trac.osgeo.org/gdal/wiki which appears to be legacy but as far as I can tell it is actually the current one, and also leads to another download page.
- The documentation for version 2.4.0 was installed as described above here.
