Installing Quantum GIS and GRASS GIS on Ubuntu 10.04 (Lucid Lynx)

While most advanced linux users will find this post elementary, as a ‘know enough to be dangerous’ linux user I often struggle with the simple tasks. With that in mind, this is a brief summary of the steps required to install QGIS and GRASS on Ubuntu 10.04.

The instructions provided by both the QGIS and GRASS websites are actually quite good, but there are a couple steps that intro users might miss. In terms of the workflow, the process is as such:

1. Add a new software repository
2. Reload the repository (note: this is what they don’t tell you)
3. Install software

Step 1: Add a new software repository
It appears there are a couple ways to do this: GUI, modify the /etc/apt/sources.list file, and through terminal. Since the directions on the QGIS and GRASS websites use the terminal approach, I did as well and then checked the results through the GUI.

The QGIS site posts the following:

sudo apt-get install add-apt-repository 
sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable
sudo apt-get install qgis

In my case, running these commands in sequence resulted in a error: “Package qgis is not available…” So to check what is happening I looked at the Software Sources (System–>Administration–>Software Sources) and specifically the second tab “Other Software”. If the second line of the code above executed, you will have a reference to “http://ppa.launchpad.net/ubuntugis/ubuntugis-unstable/ubuntu”. This is the correct URL that Ubuntu should look at to find the required binaries, but something is off.

The problem is that Ubuntu does not automatically check the repository for the software contained within it. To force an update, you have two choices. First is to use the GUI: Select the ppa.launchpad.net reference, then select ‘Edit’, don’t change anything, then select ‘Close’. The GUI will prompt that it needs to refresh, select yes. The second option would be to run: sudo apt-get update (I think). Either way, once the update completes, you can run the ‘sudo apt-get install qgis’ and it will install correctly. To install GRASS, run the command ‘sudo apt-get install grass’

I am working on the final stages of the long-delayed ‘Flat Map’ and needed to get the latest versions of the open-source GIS stack up and running. Processing for the continental U.S. is complete, the remaining steps include the creation of the index and the zonal statistics by state. Hope to have it completed by the end of October.

8th Annual KU GIS Day Symposium

GIS Day 2009 at the University of Kansas was an unquestionable success. Now in its 8th year the GIS Day Symposium continued its trend of bringing a quality mix of speakers to the university and attracting a diverse crowd from academia, government, and business. The speaker selection was balanced and had elements of GIS data structures for moving objects, open source software, biological conservation, transportation infrastructure modeling, and flood inundation modeling. The information fair (which started three years ago) had the largest vendor participation yet and the modified location in the Kansas Union, to the main lobby on the fourth floor for the information fair and Alderson Auditorium for the talks was a nice pairing. I am continually impressed with the quality of work presented in the student competition (full disclosure: I participated this year as well, more on this below).

This was the first year in the last six that I didn’t have a significant hand in the planning of GIS Day. While initially I wondered what would happen to the day, I can safely say this year was one of the best. Eric Weber (a MA student in Geography) stepped up to continue the tradition of Geography graduate student leadership, and Xan Wedel (KU Institute for Policy and Social Research), Rhonda Houser (KU Libraries), Joel Plummer (KU PhD Candidate in Geography), and Xingong Li (KU Professor in Geography) continued with their longstanding efforts as members of the Planning Committee. I can assure you that it is not easy to plan and execute a GIS Day and these folks (along with the other KU geography graduate students who helped out) deserve a lot of thanks for putting in the effort.

Personally, it was extremely gratifying that all of our hard work in previous years carried through in this the first year that didn’t involve either myself or Matt Dunbar (who was integral to GIS Day for the first five years). As a tongue-in-cheek joke, but I hope also sincere gesture, the long-term members of the planning committee listed above surprised me with a ‘Lifetime Achievement Award’ for significant contributions to the Geography and GIS communities at KU. While I recognize the intended humor in this, I really do appreciate my colleagues recognition of the many years of effort I put into GIS Day. If this year is any measure, we’ve created a framework for success and built something that can last into the future.

The presentation and videos for the day will be available on theĀ GIS Day website in the coming weeks. My presentation is available at this link. The final report of the project and data files will be posted later.
