ACM SIGSPATIAL GIS 2009, from a distance
Turning from a conference i (mostly) attended to a conference i had no excuse to attend, this week was the 17th ACM SIGSPATIAL International Conference on Advances in Geographic Information Systems (ACM SIGSPATIAL GIS 2009). Twitter didn’t reveal much discussion with a few tweets discovered with “sigspatial” and a few others referring to “ACM GIS”. No need to turn to any visualization software. I tried correlating the tweets with the session schedule and will wait to skim the papers when they arrive. (Last year they were delivered on CD.)
I’ve found one paper already, thanks to an encouraging tweet from @snittel, and it is a fabulous cross of geospatial referencing, data mining, and the social web: Twitterstand. Socially, there’s the attempt to identify persons who tweet about breaking news. Then the data mining component comes in using both a static and dynamic training corpus to distinguish news tweets from everything else. Once a tweet is identified as news, it is then added to a topic cluster (another incredibly challenging process for computers). Once a topic cluster is established they need to locate that news. They do this by extracting and locating place names (toponym recognition via natural language processing parts of speech analysis with named-entity recognition and toponym resolution via Geonames gazetteer) from the 140 character tweets and the user’s location. Then all the locations for a topic cluster are weighted and analyzed to geolocate the news cluster, then mapped.
After the cut, tweets and the abstract for the keynote.

I vaguely remember seeing a Google/Yahoo/Microsoft map interface that did something like this some years ago, but lost where.)

Keynote:
Pat Hanrahan Computer Science and Electrical Engineering Departments Stanford University Cartography and Information Presentation: A Graphics/Visualization Perspective Wednesday, Nov 4, 9:25-10:25Abstract: The purpose of a map is to present information about the earth. For millennia cartographers have perfected the craft of map-making, in the process discovering many design principles that now form the basis of cartographic information presentation. One of the challenges facing all of us is how to integrate these traditional principles into modern geographic information systems.
Not surprisingly, many of these cartographic principles apply to other forms of visualization. The first part of the presentation describes how cartographic thinking has informed information visualization. Information visualization research has benefited enormously from the work of great cartographers including Jacques Bertin and Eduard Imhof. The second part presents examples where ideas from information visualization, and progress in automating graphic design, have led to new ways to make maps. A major goal of future research should be to enable computers to present information effectively using a well-designed and beautiful map.
