Sysadmin Appreciation Day was exactly two months ago, but this gem shared by Bill Morris is too good to pass up on: (source) Then there’s of course also this classic by Randall Munroe: (source) Continue reading Be nice to your sysadmin
I was in L.A. the first time this March, before Esri’s Business Partner Conference and Dev Summit in Palm Springs. So this time-lapse film of L.A. by Sunchaser Pictures came as a nice diversion: (via BoingBoing) Continue reading Sunchaser Pictures: Angel City

I’ve mentioned it before, but now the official links have arrived for my latest work in user-generated content research: Together with Arzu Çöltekin and Gennady Andrienko I have published a paper titled Towards (re)constructing narratives from georeferenced photographs through visual analytics in The Cartographic Journal. You can find this official version here. Similarly, the article Uneven geographies of user-generated … Continue reading First two publications of 2014
Recently, I’ve stumbled across Noah Iliinsky’s Where 2012 talk When To *Not* Use Maps. The title immediately intrigued me. As a geographer and data consultant I’m convinced, an important part of my work lies in the question what tools best fit a purpose or a goal I want to achieve. But this is only one side of … Continue reading When NOT to use maps
Some days ago, Martin Elmer (@maphugger) tweeted Numberphile’s video in which they highlight the famous Minard map. Martin and I exchanged a series of tweets on the topic: Martin had some substantial criticism of Minard’s graphic. Maybe, graphic is the crucial word here: A part of Martin’s and my discussion was about the (too?) subtle geographic … Continue reading Minard’s march – a hallmark visualization, rightly so?

I also revamped the Ernst Basler + Partner GIS blog. From March to May I had an unpaid leave from Ernst Basler + Partner (EBP) and worked in the … Continue reading Happy 2014!
I have written about the ubiquity of Python before and I’ve also given a talk in that direction at this year’s FOSSGIS conference (“Python as ‘glue’ in the GIS software domain: Sun glare analysis of road traffic accidents”). There is also a video of my talk here (but beware, it’s in German). So, this post by Tal … Continue reading Ubiquity of Python

Further, Stephan and I both blog privately (see Stephan’s blog here) and within the EBP geoinformatics blog. These activities led me … Continue reading GIS blogs from the cartography country
