Article on Geo Visualization
“Neue Sichtbarkeit” in Weave design magazine 06.11 Together with Cedric Kiefer, I wrote an article on collecting and visualizing geospatial data, and how it influences the perception of our environment. After a very brief cartographic history, we argue that the massive generation of geo data in recent years might lead to information overload, yet opens [...] Read more – ‘Article on Geo Visualization’.
Interactive Exploration of Geospatial Network Visualization
An interactive multitouch visualization of relations between geo-positioned locations. Our interactive tabletop visualization is intended to be a walk-up-and-use system. In our case study on research collaboration the targeted audience are attendees at scientific conferences.

The objective of the project is to give people visual and tangible access to real-time information [...] Read more – ‘Visiting the MIT Senseable City Lab’.
Exploding Menu
Exploding Menu enables high precision selection of geo-located markers on multitouch interfaces. In a geo-visualization, in which the visual scatter shall show spatial patterns, places must be displayed at their original geo-locations. In contrast to non-geographic layout strategies, where a positioning algorithm can prevent occlusions, this may result in overlapping markers for places in close [...] Read more – ‘Exploding Menu’.
Urbane Ebenen, winter 2010
This course was about the invisible layers of data in an urban context. The aim of the final project was to create a working prototype for a multitouch table or a wall display to show these layers in interactive geo visualizations. Read more – ‘Urbane Ebenen, winter 2010’.

Flickr’s details-on-hover map
Back in June Flickr did a major redesign, with larger image displays, a cleaner interface, and lots of interaction improvements. One of the more subtle updates is the way the small map displays the location of a geo-tagged photo. The closer the user moves the mouse to the marker, the more the map zooms in.
