Evaluating Open Source GIS for Libraries

Wednesday, March 17th, 2010

I’ve hit a couple of milestones this month.

I had my first peer-reviewed journal article published, Evaluating open source GIS for libraries. After my initial exploration of open source GIS that I documented on this blog over a year and a half ago, I took a systematic approach to evaluating a number of software packages for thematic mapping. This article documents the tests and results and provides the requisite background on open source software, GIS, and how both are manifest in academic libraries. Given the lengthy process of academic publishing (the whole process began in Dec 2008 with my first test and ended in March 2010 with publication), some of my observations of individual software packages have changed with the release of bug fixes, new features, and new versions. Generally, individual software packages and open source GIS as a whole have improved during this short span of time, but my primary observations and the big picture still hold.

Title: Evaluating open source GIS for libraries

Journal: Library Hi Tech
Year: 2010 Volume: 28 Issue: 1 Page: 131 – 151
ISSN: 0737-8831

I’ve previously mentioned Steiniger and Bocher’s excellent article, An overview on current free open source desktop GIS developments in the International Journal of Geographic Information Science, which Steiniger has posted on his website. I recently discovered he’s written a second article with Hay entitled Free and Open Source Geographic Information Tools for Landscape Ecology in Ecological Informatics, which is also available there. The second article provides an in-depth look and great summary tables of landscape analysis applications for eight different open source GIS apps, focusing on advanced tools for researchers. In contrast, my article focuses on basic mapping capabilities for novice to intermediate users.

The other milestone is this blog – I just noticed that we’ve passed the two year mark. While there have only been a few public comments here and there, I have received a number of emails over the years with questions and comments and the number of visitors to the site has grown consistently from month to month. I’m glad that it’s been useful to so many people; it’s certainly been useful to me (as an extension to my feeble brain) and I’ll endeavor to keep it going. Thanks to everyone for your comments and feedback. Best – frank

Geographic Information: Literacy and Systems

Wednesday, August 5th, 2009

I’ve been spending a good portion of my summer working on the course that I’m going to teach this fall. The library at my college offers credit courses in Information Studies which students can take as a minor – they can choose two 3000 level courses and then a 4000 level capstone course. My course is a 3000 level special topics course which I’ve called Geographic Information: Literacy and Systems.

My situation is rather peculiar. I can’t teach this course as a pure GIS course, since it’s an information studies class and not geography or earth sciences. Beyond that, my college does not have a geography department, and earth sciences are not an individual department but are combined with other natural and physical sciences. With the exception of a regional geography class offered by the anthropology department, my college doesn’t offer geography instruction. So even if I could teach a pure GIS class, it’s unlikely that any of the students would have any foundational geographic knowledge.

I also can’t teach the course as a “library” class where I’m training people to be map or GIS librarians, because that isn’t the point of the info studies minor. The minor is meant to introduce students to the foundational principles of information – what is information, how do we search for it, organize it, what is its context in society, etc. I also could not teach the course as a basic software class, as that isn’t really appropriate for a college course. In short, I couldn’t find a model that I could follow, as what I’m doing falls outside these traditional realms.

So I decided to build the course around the concept of geographic information where I’ll cover some foundational geography,cartography, and GIS from an information science perspective that encompasses:  organization, search and retrieval, data processing, and assessment and analysis of GI. I’ve divided the class into four units that cover geographic information and fundamental geography, maps as information objects, and two units of GIS. In the first GIS unit we’ll cover the theoretical aspects and the basics of using the software with datasets that I’ll provide. In the second unit we’ll deal with the nitty gritty of actually searching for and processing freely available GIS data. In the last couple of weeks I’ll spend some time on web mapping and on geographic analysis and research.

Many of the concepts that I’ll be teaching are things that I never formally learned in a college course, such as a discussion of the kinds of administrative and statistical divisions that exist in the world, why they exist, and how data is collected for them. The second GIS unit on data processing is something that I feel is never adequately covered in GIS classes, but is essential for doing just about anything in GIS. I think this is also poignant in information studies, as it involves a discussion of the difference between data and information and how you can turn one into the other.

I’ve decided to use all open source software. Since these are undergraduate students who probably won’t be entering a geography related field, and we are a commuter campus where students have to make special trips to get to computer labs, I didn’t see any logic in using ArcGIS. With the open source software they can use it anywhere and there will be a better chance that they’ll use it after the course is over (and after they graduate). I’ve opted to go with QGIS as it covers all the bases I need. I liked gvSIG but had too many problems with the map layout – I might be able to cut my way through them, but can sophomore business and english majors? QGIS is also more thoroughly documented (in english), which is important since this is an introductory class.

I’m using Krygier and Woods Making Maps as my textbook, along with a few chapters here and there from other texts. I have looked to the pages Krygier’s created for his courses for guidance, and like the stream of consciousness style he used for writing his notes. I’ll post an annotated reading list later.

Since I’m breaking molds, I’ve also decided not to use Blackboard to organize the whole course and am using a blog and various other bits and pieces of software for creating assignments, organizing the roster, etc. If you’re interested you can follow along on my course blog – (only students can register). Classes start on August 31st…

Updated Links for Data and Resources

Saturday, April 25th, 2009

I recently went through my pages of suggested links for data and resources to update and clean them up. I’ve included many of the cool resources I’ve discovered since I started writing this blog, which ended up in individual posts but not in these pages. I went over the resources page in particular, to try and classify the reference materials, tools, and software into useful categories rather than just having one large blob of stuff.

Comments Disabled

Tuesday, February 24th, 2009

Because I’m being spammed to death, I’ve disabled the ability for anyone to leave comments on posts and have restricted it to registered users only.

But for some reason, when someone registers for this blog they aren’t sent an email confirmation with a temporary password as there is something wrong with the configuration of my email server and how it communicates with WordPress. I know of one possible solution that I’m going to try this weekend to fix this. Until then, no one will be able to leave comments or officially register. Hopefully I can get this straightened out soon…

Red States / Blue States

Saturday, August 23rd, 2008

It’s been a busy summer – I’ve spent a good chunk of it working on an election mapping project. The library wanted to create a resource for students to use for the upcoming 2008 presidential election. Here it is:

Red States, Blue States: Electoral Strategy Behind the Map

A few of the procedures and issues I encountered while working on the project became fodder for a number of posts to this blog, so I thought I’d share the end result.

I’ve also been assembling data and pages for a server I’ve been given to provide GIS data at Baruch, and have been investigating open source alternatives to ArcGIS. More on that later…

Monday, March 31st, 2008

ESRI has just released another service pack for ArcGIS – Service Pack 5, which fixes a number of bugs and adds some additional functionality.

Innagural Post

Tuesday, March 11th, 2008

Welcome to my little world of Gothos! Here, I will share my experiences, tips, musings, knowledge, mistakes, opinions, and thoughts as a geography / GIS librarian. We’ll cover data sources, data processing, map making, resources, and more. I’ll also post relevant announcements for the local GIS community at CUNY and beyond. Where possible, I’ll also share some of my work: maps, reference guides, and datasets. See the About page for additional info.
