Geotracing my September-October

The last 40 days, I sadly increased my contribution to global warming in releasing NOx, CO, HC and SO2 to propel me around Europe and California. Below I try to compare the “geotraces” I left using (semi-implicitly) Plazes and (implicitly) Flickr. I generate the Plazes’ traces using Pascal’s jplazes.

Relation to my thesis: I am interested in the use of implicitly and explicitly collected “geotraces”. More specifically I would like to understand what level of quality/granualrity of the location information users need (when and in what context). and their visualizations.
Currently, Paul is running a little experiment on tracking his days. I aim at similar little side experiment with the daily use of a GlobalSat BT338 and GSM cell-id based positioning. The purpose here is to understand the potential of implicit trace generation with behavior inference based on location data.
