Underdark at Free and Open Source GIS Ramblings reports of a great new addition to the QGIS Wiki – a set of step by step tutorials complete with graphics and categorized into tasks dealing with vectors, rasters, map projections, spatial analyses, format conversion and map making. This is a great reference for anyone just beginning to get their feet wet as well as for existing users trying to get a glimpse of the latest features.
With all the rave reviews that Ubuntu 10.04 Lucid Lynx has been getting over the past couple of months, I couldn’t help myself upgrading and checking out the exciting new features and the enhanced interface, which I think was a much needed overhaul for the best desktop Linux OS.
A new version meant fresh installation of all the open source GIS goodies starting with QGIS. The latest version 1.4.0-Enceladus for Lucid is already available in the Launchpad UbuntuGIS repository and with a new command (add-apt-repository) for updating /etc/apt/sources.list with locations of repositories, the installation is simple and straightforward.
Bring up the terminal and issue the following commands.
Add the repository using:
sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable
Make apt aware of the new repository:
sudo apt-get update
Install QGIS
sudo apt-get install qgis
Once the installation is done, open QGIS from Applications -> Science -> Quantum GIS
For first time users, here are steps to help you guide through the installation.
Bring up the terminal (Applications -> Accessories -> Terminal)
Edit the /etc/apt/sources.list by issuing the command sudo gedit /etc/apt/sources.lists
Scroll down to the end of the page and paste the following lines:
deb http://ppa.launchpad.net/qgis/ubuntu jaunty main
deb-src http://ppa.launchpad.net/qgis/ubuntu jaunty main
Saving and closing the file, brings back the prompt.
Update the package lists using the command, sudo apt-get update
Install Quantum GIS with sudo apt-get install qgis
Ignore any GPG errors that show up for public keys that are not available.
Access Quantum GIS from Applications -> Education -> Quantum GIS
