which supports OSM
● osm2pgsql (importing OSM into PostgreSQL)
● mapnik (cartographic rendering)
● monav (routing engine and application)
● OpenLayers (web maps)
● + much much more....

13. Low Adoption Barrier
● Existing worldwide minutely web map updates
● www.osm.org
● Daily OSM extracts available for you to import into
existing GIS systems
● download.cloudmade.com
● Easy for new users to get started
● potlatch2

14. Contributing to OSM
● Ground survey
● With a GPS
● Without a GPS (eg. walking papers)
● Tracing aerial imagery
● Providing existing data under a free licence
● Editors: Potlatch2, JOSM, Merkaartor
