GDAL

Installation

Best install using standard system package manager, such as apt-get (Ubuntu), yum (Fedora), or macports (OSX).

Download

The current download page is http://download.osgeo.org/gdal/. However, web searches for the code or documentation lead to many dead links to defuncts sites. In particular, almost all links leading inside https://gdal.org/ from internet search engines are dead.

Documentation

• Web searches for "gdal documentation" are futile, but there is index to just that at https://gdal.org and wiki https://trac.osgeo.org/gdal/wiki, which also links to alternative download pages. But that wiki seems old, there is a new wiki at https://wiki.osgeo.org/wiki/Main_Page.
• The software installs without man pages and typing gdal utilities from the command line with -help gives only a brief list of options. But the following works:
  • Download the appropriate version of sources as tar.gz file and expand the file
  • install doxygen if needed, and type doxygen in the top directory of the source
  • Open html/index.html in a web browser
• Documentation was installed as described above for version 2.4.0 and version 3.0.0
• There is https://live.osgeo.org/en/quickstart/gdal_quickstart.html

Glossary

• WKT: text markup language for representing vector geometry objects
• SRS: Spatial reference system: a complete set of parameters that determine how to associate a point on a map with a point on the Earth surface (system of coordinates, map projection, and datum).
• Latitude - there is more than one because the Earth is not a sphere
