QGIS versus ArcMap

by

story imageThe QGIS Project released the latest 2.4 version of their free and open source QGIS geospatial information system software a week or so ago (codename Chugiak). The 2.4 changelog lists a number of new features that indicate the QGIS software is increasing in data analysis and map composing sophistication, i.e., moving beyond its traditional strength as a geospatial data management interface. One new feature that seems especially exciting is the multi-threaded rendering which allows users to continue to interact with the map views while re-rendering of the map is ongoing.

Anyway, I've been using QGIS almost exclusively in my own research for the past five years or more -- although I have been preparing final figures and maps using Generic Mapping Tools scripts because of perceived limitations with previous iterations of the Map Compositor functionality in QGIS. However, my place of work and many of my colleagues continue to use the commericial ArcGIS suite of software for GIS and Map preparation tasks and so, out of necessity, I am constantly switching back and forth between the two.

I remain convinced that for many people's workflows, QGIS is a hugely competitive product because it is free and supports a wide range of GIS activities. QGIS functions are only getting more numerous and sophisticated with time.

I thought I would take the 2.4 release of QGIS as an opportunity to ask the Pipedot community if they had any ongoing experience switching from ArcGIS to QGIS or supporting both platforms concurrently? As well, what points of comparison would Pipedot contributors emphasize in considering the QGIS versus ArcMap question? Thanks!

Distro Friday: GALPon MiniNo

story imageI got the idea when writing up that article about Distrowatch: they cover so many distros and so many of them are so obscure; I decided to check some of them out. Conveniently - as though they're tempting me - there's a "Random Distribution" button on the front page of Distrowatch, which makes it easy. Every Friday I propose a roll of the dice, and a quick look at some distro you've probably never heard of. I'll try to give equal coverage to the BSDs too.

If this is annoying or not interesting to you, quick! Flame me to a cinder in the comments. Otherwise, enjoy what will hopefully be a weekly feature that will lead to interesting commentary and comparison. I'll be skipping the big guys (RedHat, openSUSE, Ubuntu, etc.) since the purpose is to give some exposure to the obscure/niche stuff. These aren't reviews since I don't have time to install and try each one.

Today's distro is GALPon MiniNo, which gets my vote for the "least memorable name for a distro, ever." But it can be explained: GALPon is the Linux User's Group of Pontevedra, Spain, in the region of Galicia. And they're actively working to get Linux in schools, especially where equipment is old or low-powered and often recycled. No surprise then that GALPon MiniNo emphasizes low system requirements: it installs on machines with 128M of RAM and 4GB hard drives, and uses IceWM or Openbox, RoxFiler, and the like to stay light. It also supports Galician and Catalan - regional languages of Spain - out of the box. Looks like it will install nicely on a netbook or liveCD.

I'm a big fan of lightweight distros to counter the otherwise endless bloat of the big guns. I might have to try this one out and give Puppy a run for its money. Read more (in Spanish) at their homepage, their help and documentation (also Spanish/Galician), or their Google group forum.
