A few months back I published an article about the large scale deployment of QGIS and FOSSGIS at the state administration of Vorarlberg, Austria. Shortly after I published the article, they asked for the opportunity to update the article with more details. The article that follows below is that amended version. In 2011, the State...

Today is Open Data Day 2013. I did’t have much time to hack, but I made a few tweaks to my ‘just for fun’ osm-reporter project to provide average, min and max counts per active day for each user. I also did a bunch of code cleanups under the hood which probably nobody except me... Read more »
Yes I know its a bit wierd to see the word ‘OSX’ in an article by me…I recently bought a Mac for testing InaSAFE and fooling around with FOSSGIS software on OSX. Besides the 2 or three days it took to get it set up as a development machine for FOSSGIS stuff (as compared to... Read more »
This weekend I implemented a new feature for my ‘just for fun’ project osm-reporter. The feature implements timeline reporting for Open Street Map contributors. Its probably easiest to explain with a screenshot: Here is another one showing a few charts together: I added the feature because I wanted to see how many... Read more »
A couple of weeks ago I had the pleasure of doing an interview on behalf of the InaSAFE project as part of the selection process for the Black Duck Software ‘open source rookies of the year’ competition. A week later we heard that we had made it into the top 10! The award is based... Read more »
In 2011, the State of Vorarlberg, Austria became a new sponsor for the QGIS project. I was quite interested in the work they were doing as they are yet another great example of QGIS and FOSSGIS being used in an enterprise level setting. I arranged with Nikolaus Batlogg at the time to check in with... Read more »
Here is a little update to my last post. I quickly whipped up a web app for the little stats script I wrote. It is available at http://osm.linfiniti.com. The stats only update once per hour so as not to hammer the osm export server. The code is all open source (https://github.com/timlinux/osm-reporter), written in python and... Read more »
If you even visited my lovely home town of Swellendam in the Western Cape of South Africa on http://openstreetmap.org, you might have noticed that the building footprints for the town are almost non-existent. Building footprints provide a valuable way to understand impacts of flood and other natural hazards, as well as being a valuable source... Read more »
Anton Westholm just published this great article on using QGIS and blender to create 3D visualisations: http://kodex.tumblr.com/post/37038839550/visualising-qgis-data-with-blender
I have been working a lot in Indonesia this year on the InaSAFE project. InaSAFE is a QGIS plugin (also available as a web extension for GeoNode) for assessment of scenarios following a natural disaster such as a flood, earthquake, volcano, tsunami etc. This month the InaSAFE team (which consists of developers from around the...

In the last few weeks we merged the work from the QGIS SEXTANTE project into the official QGIS repository’s master branch. This means basically that in QGIS 2.0 SEXTANTE will be a default plugin, available immediately on installation of QGIS. SEXTANTE uses a pluggable architecture, providing front ends to SAGA, GRASS, Orpheo Toolbox, MMQGIS and... Read more »
Today we got another nice new feature in QGIS master – a pimped out python console! The improvements were implemented by Salvatore Larosa with some hints and help from Larry Shaffer. Read on for more details! There are a number of improvements which center around Salvatore using the PyScintilla editor widget. Probably the most... Read more »
We (the QGIS PSC) had a nice message from a QGIS user today: I’m a GIS user located in the U.S. and I recently received an email offering several FREE GIS softwares for the low price of $785. I’m not sure how I got on the email list, but it really made me angry that someone... Read more »
Here is a quick tip on how to make QGIS less noisy on the command line. I write quite a few command line based apps (typically in python these days) and I got kinda bored of looking at the reams of stuff that gets put onto stdout like this: src/core/qgsproviderregistry.cpp: 219: (QgsProviderRegistry) Checking /usr/local/qgis-master//lib/qgis/plugins/libheatmapplugin.so :...

Wow it’s been a long time since I posted anything here….but I’m back with another (hopefully) useful howto. Over the last six months or so I have made a rather dramatic shift away from using VIM as my primary development environment for everything to using IDE’s for my python development work. I spent the first... Read more »
