The new Geographic Information Systems Stack Exchange site is now open to the public!
It’s brand new, and has the potential to be an extremely valuable resource for GIS professionals, academics, enthusiasts, and just about anyone else looking for answers to GIS related questions.

Last night I had an uncontrollable urge to make geopoprocessing in QGIS better, faster and more fun! I had come across a couple of posts (here, here) on the idea of a cascaded union operation, and since it has recently been added to GEOS (which QGIS uses for its geometry operations), I thought I’d give a much needed boost to the fTools union tool and related functions.

Last week I attended the 2009 QGIS Developers Meeting in Vienna, Austria. We all had a really good time, met many new people, and actually got a lot done in the process. There have been updates about the meeting (hackfest) on the QGIS blog, and Tim Sutton has written a few words about our progress as well. I’m not going to repeat what others have said, but I would like to give a quick update on the work that I was doing at the meeting, and show off the new geoprocessing features now available to all QGIS developers (Python and C++).

My article “Spatial-temporal patterns of snow cover in western Canada”, has now been published on-line with The Canadian Geographer. At this stage, only the proof copy is available online.
UPDATE:
The article is now officially published, and can be cited as:
Farmer, C. J. Q., Nelson, T. A., Wulder, M.A. and Derksen, C. (2009). Spatial-temporal patterns of snow cover in western Canada, Canadian Geographer, 53 (4): 473-487.
If you would like a copy, but do not have access to the article, please email me and I can forward you a PDF version.

My latest article, “Identification of snow cover regimes through spatial and temporal clustering of satellite microwave brightness temperatures”, has recently been published on-line , with the journal Remote Sensing of Environment. For now,

Announcing an opportunity to learn about the leading edge free and open-source technologies for desktop and web-based mapping and data analysis. This is a two day Masterclass focusing on introducing participants to the wonderful world of open source geospatial software. Check out the announcement from the Postgraduate Statistics Centre at Lancaster University.

Two quicks notes to share:
Firstly, please check out this excellent introduction to GIS by Tim Sutton, Otto Dassau, and Marcelle Sutton in partnership with the Chief Directorate for Spatial Planning & Information, Department of Land Affairs, Eastern Cape, South Africa, and the Spatial Information Management Unit, Office of the Premier, Eastern Cape, South Africa. They use QGIS to present some basic GIS concepts and skills, and I particularly like their section on Coordinate Reference Systems.
Secondly, don’t forget to checkout the FOSS4G 2009 Free and open source software for geospatial conference in Sydney in October. There will be loads of excellent presentations and exhibitors, and the atmosphere is always very cool. I will be presenting some software that I’ve been developing for a while now, and will hopefully get a chance to represent QGIS there as well!
