Transcript

  • 1. Participatory mapping with OpenStreetMap in Ulaanbaatar 08/10/2013 Severin Menard & Russell Deffner Humanitarian 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 Endeavour This approach brings at least public savings and allows a fair competition between companies, what strengthen economics.
  • 3. 1 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. = + www.osm.org What is OpenStreetMap? It is based on the joint action of thousands of contributors working voluntarily. Anyone can participate!
  • 4. OSM focuses on all the visible, physical objects like: roads, buildings, land uses, facilities (health, education..) shops, industries, water and sanitation, natural spaces... but also not visible like administrative boundaries or transportation lines. OSM does not store information about populations. 1 www.osm.org Mapping any feature existing in the field, visible or not
  • 5. 1 History and Stats http://wiki.openstreetmap.org/wiki/History_of_OpenStreetMap Since 2004 the project grew up beyond 1,300,000 user accounts and more than 2 billion nodes created. http://wiki.openstreetmap.org/wiki/Sta The ongoing OSM contributions can be followed on http://live.openstreetmap.fr/ One year of edits can be watched on http://vimeo.com/56374742
  • 6. 1 “Legal” Details Was Licensed CC-BY-SA 2.0 Moved towards ODbL Kate Chapman's article about OdbL: http://www.maploser.com/2012/03/03/odbl-what-the-heck-can-you-do-with-it/
  • 7. 1 OSM governance The ecosystem of the OSM community Citizens Associations Local governments NGOs International Organizations (UN, WB) Academia Private actors: • Microsoft, Foursquare • Cloudmade, Geofabrik, Camptocamp, MapBox The growth of the OSM project is fostered by • OpenStreetMap Foundation & local Chapters (, ) • Humanitarian OpenStreetMap Team () Hum/Dev contexts
  • 8. 1 La cartographie Collaborative Idea: A large number of individuals contributing together will tend to create high quality data. Different kind of practises and tools strengthen this. Free mapping and quality
  • 9. 1 OSM Wiki http://wiki.openstreetmap.org http://wiki.openstreetmap.org
  • 10. 1 http://lists.openstreetmap.org/listinfo OSM mailing lists (geographic, thematic)
  • 11. 1 Training materials: LearnOSM. for Beginners, Intermediate, Advanced Mappers or Trainers http://learnosm.org
  • 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. History 1 The complete history of every object is accessible
  • 15. History 1 It is possible to know what has been updated recently over an area
  • 16. History 1 It is possible to know who are the active contributors in an area
  • 17. 1 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 The quality of OSM data demonstrated by scientific researches
  • 18. 1 OSM is a free map, not submitted to political constraints Example in China where OSM has no random offset
  • 19. 1 What are the OSM topological features?
  • 20. 1 OSM Data Structure Based on the idea of key/value pairs highway=primary name=I66 building=yes address=123 Main Street city=Somewhere amenity=hospital name=Sacred Heart
  • 21. 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 : http://wiki.openstreetmap.org/wiki/Map_Features
  • 22. 1 Contributing to OSM: mapping over Imagery Bing allows the OpenStreetMap contributors to trace over all its imagery.
  • 23. 1 Coordinating tool: the Tasking Manager http://tasks.hotosm.org/
  • 24. 1 Contributing to OSM: field mapping, Mapping Parties
  • 25. Most Any GPS Will Work 1 Tools to contribute in OSM: GPS devices
  • 26. 1 OpenStreetMap services: Maps for GPS devices
  • 27. 1 Tools to contribute in OSM: Walking of Field Papers http://walking-papers.org/ or http://fieldpapers.org/ Printable Map Collect Data by Writing Scan and Upload Edit for OpenStreetMap
  • 28. 1 Survey forms: fitting humanitarian data models (ex: UNDIT for roads)
  • 29. 1 OpenStreetMap services: Editors for smartphones OsmTracker - Routing - Pedestrian - Edits/Bugs - Edits/Bugs & transports Vespucci - light online editor - online - Edits/Bugs
  • 30. 1 Java Based OpenStreetMap Editor http://josm.openstreetmap.de/ Can be easily enhanced, many plugins, works well with sporadic connectivity
  • 31. 1 JOSM Presets Simplifies Editing Creates Editing Forms XML Based
  • 32. 1 OSM core – system components
  • 33. 1 A specific humanitarian rendering for OSM
  • 34. 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. https://www.youtube.com/watch?v=3XPvVcUNrjQ
  • 35. 1 The OSM map after the Earthquake: the best map of Port-au-Prince ever Port-au-Prince on OSM, January 12, 2010 Port-au-Prince on OSM, 28 days later
