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 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.
