People at Zurich electricity provider ewz have recently kindly invited me to give a keynote presentation at one of their telematics events.
The task was to sketch emerging trends in GIS and visualisation from three perspectives: as GIS consultant at Ernst Basler + Partner, as a researcher at Oxford Internet Institute and as an individual that sometimes undertakes GIS and geovisualisation projects. I ended up highlighting four big trends that I think will continue to control developments in GIS/visualisation (although I will concede that certain aspects of these trends are over-hyped here and there). The actual keynote consisted of significant interactive parts, but I embed the slides here in case you want to check out trends and examples: Continue reading “Keynote about trends in GIS and visualization”
After my project proposal had been accepted, I have attended a workshop at ETH Zurich, titled “Cartography & Narratives” organised by Barbara Piatte, Sébastien Caquard and Anne-Kathrin Reuschel in last summer. The goal of the workshop was to explore “mapping as a conceptual framework to improve our understating of narratives”. Narratives are “an expression in discourse of … Continue reading Flickr as a vehicle of narrative: photos contextualised in space and time
I just got news that TileMill now also runs on Windows (besides Mac OS and Linux). TileMill is a browser-based tool to prepare map tiles which you can, for example, overlay on Google Maps or use as basemap in a Processing sketch. The latter of which I have in my ZIPScribble maps series (here, here or … Continue reading TileMill available for Windows, too
“Einigkeit und Recht und Frei-ei-heit…!” But before we get to that, as explained earlier, there are different levels in my ZIPScribble Maps: Level 1 ZIPScribble Map: Only the first digit of the postcode is compared. Thus, a discontinuity is detected, for example, between postal codes 8679 and 9000, but no discontinuity is detected between 8399 and 8400. … Continue reading ZIPScribble Map Germany

Earlier I’ve blogged a two-parts tutorial on how to create ZIPScribble Maps using the Processing visualization framework. The map uses a background I made with TileMill and CC-BY-licensed postcode data from the Geonames gazetteer portal. (By the way, here’s an informative short TileMill tutorial by Pierre La Baume) As explained earlier, there are different levels … Continue reading ZIPScribble Map Italy
Having seen a visualization by Robert Kosara of EagerEyes a loooong time ago, I wanted to try to reproduce it for Switzerland using Processing. This is the second installment of a two-parts post covering this project, in which I will describe how to arrive at the final result, the ZIPScribble Map. I’ll do that in some detail, maybe this is helpful to somebody.
In the first installment of this series I explained my process up to an intermediate result: a map depicting all the postal code locations in Switzerland, like this:
This involved creating a basemap with TileMill, using Till Nagel’s MercatorMap class in Processing, finding and downloading postal code data from Geonames and writing a Processing sketch which makes use of all these. In this second installment I will explain how to arrive at a ZIPScribble Map for Switzerland from the above intermediate result. So from the first part we have many things in place already. What is missing are basically three things: Continue reading “ZIPScribble Map: Switzerland – Part II”

The visualization is called the ZIPScribbleMap: “ZIP” for postal codes, “Scribble” for rather obvious reasons (as in “it looks like what I doodle while on the phone!”): Continue reading “ZIPScribble Map: Switzerland – Part I”
Till Nagel has a tutorial on using custom maps as backgrounds in Processing sketches. The solution uses TileMill, a map design environment which allows you to export a customised static map as an image for use in Processing. For advanced users, Till Nagel also describes the procedure for interactive tiled maps. That latter solution relies on an … Continue reading Using customised basemaps in Processing
Starting from yesterday the Processing team offers Processing 0195 pre-release for download. Lots of bugs have been fixed and 0195 is considered a stepping stone for a Processing 1.5 stable release in a few days. (via Ben Fry) Continue reading Processing 0195

For quite some time I’ve been following the news about Processing. Processing is an open-source environment for creating visualizations programmatically. The project was initiated by Casey Reas and Benjamin Fry in the Media Lab of the MIT.
Processing encompasses both the Java-based Processing programming language and an Integrated Development Environment, IDE, in which to write code. Processing enables users to generate rather complex graphics and animations (also with interactivity). Considerably fewer code is needed to implement something in Processing rather than in Java itself.
According to the website some of Processing’s feature highlights are: Continue reading “Intro to Processing”
