Introduction
MEPIS 7 users can easily set up a Geographic Information System (GIS) using open-source components.
Quantum GIS
Introduction
Quantum GIS (QGIS) is a user-friendly open-source geodata viewer that supports vector, raster, and database formats.
Installation
An older version (0.7) is available in the MEPIS 7 repos. Install:
qgis
If you want to use QGIS as a front end for Grass, then also install
qgis-plugin-grass
which will install Grass (see below) and the needed dependencies.
To update to a more recent version (currently 0.9), download this package. The package includes four deb files, one of which we will ignore here.
A dependency requirement needs to be fulfilled first. Using a terminal, type as root:
apt-get install libqt4-qt3support
If that runs into dependency problems, follow the onscreen directions and enter:
apt-get -f install
which will complete the installation.
Now we can install the new version of QGIS. Double-click and install with Kpkg this file:
libgis1_0.9.0_i386.deb
then this:
qgis_0.9.0_i386.deb
Finally, if you are going to be using Grass, then you want to also install the updated Grass plugin. First you need to download and install a dependency. Go to this page, then right-click, save and install this deb file:
libgdal1-1.3.2-grass_1.3.2-1_i386.deb
Once that has installed, then you can install from the qgis 0.9 package you downloaded:
qgis-plugin-grass_0.9.0_i386.deb
and you should be good to go!

Grass
Introduction
Grass is a Geographic Information System (GIS) used for geospatial data management and analysis, image processing, graphics/maps production, spatial modeling, and visualization. It can be used standalone, or as a powerful backend to QGIS.
Installation
Grass 6.0.2-6 is in the MEPIS repos. Install:
grass grass-doc
The current version available from the home page is 6.2.3, but while it would be desirable to upgrade because of the development in the GUI, a number of unmet dependencies would have to be satisfied to install it in MEPIS 7 as long as the distro is based on Debian Etch.

Other applications
Other applications are available that are useful for GIS operations:
- R -- the statistical package
- GPS Babel -- app for handling various GPS languages
- Generic Mapping Tool (GMT) -- collection of tools for manipulating data sets
- PostGIS -- adds support for geographic objects to the PostgreSQL
- gvSIG - a tool oriented toward managing geographic information
- uDig -- a user-friendly web-oriented GIS
