  2. Origins of OpenStreetMap “The Wikipedia of Maps” Started in 2004

    in the UK Map originally based on nothing but volunteers’ GPS traces and notes

  6. License CC-BY-SA until 12 September 2012 Now: ODbL CC-derived Open

    Database License Main difference: produced works (such as rendered maps) require attribution, but not share-alike only adapted databases trigger share-alike wiki.osm.org/wiki/Open_Database_License

  15. The question of imports

  16. OSM TIGER Import Stands for “Topologically Integrated Geographic Encoding and

    Referencing” TIGER is a product of the United States Census Bureau, therefore in the Public Domain OpenStreetMap imported TIGER’s 2005 data starting in late 2007: animation: wiki.osm.org/wiki/Tiger
  17. wiki.osm.org/wiki/Stats

  18. Imports beyond TIGER

  19. 19 Buildings without addresses

  20. Addresses without buildings

  21. Landcover

  22. Incomplete landcover import

  23. Critiques of imported data: Low data quality Destroys volunteer contributions

    Discourages new contributors
  24. Current best practice wiki.osm.org / wiki / Import / Guidelines

  25. Community Imports • Divide data into chunks • Community members

    manually upload each chunk NOTE: The term "Import" is highly loaded in the OSM community. "A distributed and curated merge," is a more accurate description of what Seattle OSM planning to do. — wiki.osm.org/wiki/Seattle_Import
  26. Building community through imports Four training events and editathons Five

    events out walking around 20+ active participants slideshare.net/gwhathistory/osm-sotm-us-2013-imports4community-002
  27. NYC community building import • Estimated 1500 hours of work

    • Volunteers + Mapbox employees • Coordination with NYC GIS Dept animation: mapbox.com/blog/nyc-buildings-openstreetmap
  28. LA County building import (still in planning stage) 3,141,244 building

    footprints 6,423 block groups github.com/osmlab/labuildings
