OSM issues

  • Threshold of entry
    • Newbies
    • Editor
    • How to
    • Community
  • Continuous validation
  • Imagery

Why OSM important

  • It open for usage and editing
  • It mostly the best map (especially outside cities)
    • bicycle roads
  • It already help
    • ambulance (and fire?) cars on call
    • on rescue operation after flood or earthquake

Why not Google/Yandex

  • Terms of usage
  • Thousands requests + limits can be slow
  • Can't get or work with pure data (API only)
  • Can't fix (or limited?) mistakes or improve
  • Mostly worse coverage

Why not Wikimapia

  • Unclear data license (used Google Maps)
  • Pure editors and other tools
  • Category and text description
    • 3D mapping?
    • Speed limits?
    • Turn restrictions?
  • Mostly worse coverage

OSM community

OSM Belarus

  • Belarusian names
  • Government organisations mapping
    • pure contact with community
    • bad changes
  • POI is pure
