    • 1. OpenStreetMap: editing and tasking mechanisms 26/03/2013 Severin MenardHumanitarian OpenStreetMap Team (AKA H.O.T.)
    • 2. 1 What is open data ? A piece of data is open if anyone is free to use, reuse, and redistribute it — subject only, at most, to the requirement to attribute and/or share-alike. No discrimination against Persons or Groups, or Fields of Endeavor. This approach brings at least public savings and allows a fair competition between companies, what strengthen economics.
    • 3. 1 What is OpenStreetMap? OpenStreetMap is a web project aiming at creating a world map of the entire world, accessible free and downloadable for anyone. It has been started in 2004 by a student from UK. It is based on the joint action of thousands of contributors working voluntarily. Anyone can participate! = +
    • 4. 1 Mapping any visible, physical feature OSM focuses on all the visible, physical objects like: roads, buildings, land uses, facilities (health, education..) shops, industries, water and sanitation, natural spaces... OSM does not store information about populations.
    • 5. 1 History and Stats Since 2004 the project grew up beyond 1,000,000 user accounts and more than 1 billion nodes created. The ongoing OSM contributions can be followed on One year of edits can be watched on
    • 6. 1 “Legal” Details Was Licensed CC-BY-SA 2.0 Moved towards ODbL Kate Chapmans article about OdbL:
    • 7. 1 OSM governance The ecosystem of the OSM community Citizens Associations Local governments NGOs International Organizations (UN, WB) Academia Private actors: • Google, Microsoft, Foursquare • Cloudmade, Geofabrik, Camptocamp & DevelopmentSeeds The growth of the OSM project is fostered by • OpenStreetMap Foundation & local Chapters (, ) • Humanitarian OpenStreetMap Team () Hum/Dev contexts
    • 8. 1 Free mapping and quality Idea: A large number of individuals contributing together will tend to create high quality data. Different kind of practises and tools strengthen this. La cartographie Collaborative
    • 9. 1 OSM Wiki
    • 10. 1 OSM mailing lists (geographic, thematic)
    • 11. 1 Documentation: Floss Manual
    • 12. 1 Quality assurance in OpenStreetMap : validation tools for users within the editors
    • 13. 1 Quality assurance in OpenStreetMap : Specific checking services Eg: Keepright!
    • 14. 1 History The complete history of every object is accessible
    • 15. 1 The quality of OSM data demonstrated by scientific researches The analysis shows that, where OSM was collected by several users and benefited from some quality assurance, the quality of the data is comparable and can be fit for many applications. The positional accuracy is about 6 metres, which is expected for the data collection methods that are used in OSM. The comparison of motorways shows about 80% overlap between OSM and Ordnance Survey . Quality: Muki Aklay (UCL) positional accuracy comparisons United Kingdom: OSM - Ordnance Survey Meridian II database Haiti: OSM - GoogleMapMaker – MINUSTAH/CNIGS
    • 16. 1 OSM is a free map, not submitted to political constraints Example in China where OSM has no random offset
    • 17. 1 What are the OSM topological features?
    • 18. 1 OSM Data Structure Based on the idea of key/value pairs highway=primary building=yes name=I66 address=123 Main Street city=Somewhere amenity=hospital name=Sacred Heart
    • 19. 1 How tags/attributes are defined? If the tagging system is fully flexible, allowing anyone to create new keys/values, it is strongly recommended to use the already existing, debated, approved and described tags so that the OSM data remains consolidated as much as possible. The OSM tags can be found on the wiki :
    • 20. 1 Contributing to OSM: mapping over Imagery Bing allows the OpenStreetMap contributors to trace over all its imagery.
    • 21. 1 Contributing to OSM: Mapping Parties
    • 22. 1 Tools to contribute in OSM: GPS devices Most Any GPS Will Work
    • 23. 1 Tools to contribute in OSM: Walking of Field Papers or Printable Map Collect Data by Writing Scan and Upload Edit for OpenStreetMap
    • 24. 1 Tools to contribute in OSM: Walking of Field Papers or
    • 25. 1 Les outils utilisés : Tools to contribute annoter les cartes de terrain à in OSM: Walking of Field Papers or
    • 26. 1 Tools to contribute in OSM: editors Potlatch JOSM
    • 27. 1 Potlatch The Editor when you go to and hit “Edit” Easy for beginners but limited and requires a permanent connection
    • 28. 1 Java Based OpenStreetMap Editor Can be easily enhanced, many plugins, works well with sporadic connectivity
    • 29. 1 JOSM Presets Simplifies Editing Creates Editing Forms XML Based
    • 30. 1 OpenStreetMap services: Routing Tools

    • 34. 1 OpenStreetMap services: Maps for GPS devices
    • 35. 1 OpenStreetMap services: Maps for smartphones OsmAND - Routing - Pedestrian - Edits/Bugs - Edits/Bugs & transports
    • 36. 1 OpenStreetMap services: Editors for smartphones OsmTracker - Routing - Pedestrian - Edits/Bugs - Edits/Bugs & transports Vespucci - light online editor - online - Edits/Bugs
    • 37. 1 OpenStreetMap and humanitarian data Interest for an open data, easily accessible for crisis response and quickly created by a numerous community of contributors started with the earthquake that hit Haiti on January 12, 2010. This major disaster affected the Capital City, Port-au-Prince, and the towns on its west side, causing maybe 200 000 casualties. Within a few days, the response of the OSM community to map the affected areas has been intensive.
    • 38. 1 The OSM map after the Earthquake: the best map of Port-au-Prince ever Port-au-Prince on OSM, Port-au-Prince on OSM, January 12, 2010 28 days later
    • 39. 1 A new interest from the humanitarian organizations to work with the virtual, technical communities
    • 40. 1 Free mapping and open data, a new humanitarian field A NGO has been created in August 2010 to create a bridge between the community of OSM contributors and the humanitarian and development stakeholders. Humanitarian/ Development organizations An organization working to promote the use of open data and volunteered geographic information within the humanitarian and development contexts The Humanitarian OpenStreetMap Team activate a response to quickly provide baseline data to the humanitarian stakeholders. The Humanitarian OpenStreetMap Team also works on field projects in Indonesia (AusAID), Haiti (USAID), Senegal (IOF), Burundi, CAR, Chad, Kenya (DG ECHO), in order to both create baseline data and build up local capacities by training future trainers to OSM techniques.
