Libraries
I studied Computer Science at the Technischen Universität Berlin. As part of my diploma thesis I wrote a federated search engine for German university libraries called ZACK Gateway.
OpenStreetMap
My OpenStreetMap contributions:- BBBike: is a route planner for cyclists in Berlin. It is now ported to other cities around the world - thanks to the OpenStreetMap project!
- map compare: shows you different maps from OpenStreetMap, Google, Bing, Esri, Here and others side by side
- extracts service: allows you to extracts areas from Planet.osm in OSM, PBF, o5m, Garmin, Osmand, mapsforge, mbtiles, GeoJSON, Organic Maps, SVG or Esri shapefile format.
- tag name search: a fulltext search in more than 145 mio name, notes, description tags in OpenStreetMap by words, sub-strings, phrases, regular expressions, or best match
