About the Blend
The Debian GIS Pure Blend is a project of the Debian GIS Team who collaborate on maintenance of GIS related packages for Debian. Every Pure Blend is a subset of Debian that is configured to support a particular target group out-of-the-box. This blend aims to support the needs of those working with map data, remote sensing and earth observation.
The Blend is built from a curated list of GIS software in Debian. The two main outputs from the Blend are a collection of "metapackages" and live images that can be put onto a DVD or a USB stick.
Metapackages
Metapackages in Debian are packages that can be installed just like other packages but that do not contain any software themselves, instead instructing the packaging system to install a group of other packages.
See using the metapackages for more information on which metapackages are available and how to install the metapackages on an existing Debian system.
