Humanitarian OpenStreetMap Team [H.O.T.] Training for SBTF
- 1. Openstreetmap and the Humanitarian Openstreetmap Team Stand By Task Force – 17 March 2013
- 2. OpenStreetMap A web project to create a free and open map of the entire world, built entirely from volunteers surveying with GPS, digitizing aerial imagery, collecting and liberating existing public sources of geographic data. = +
- 3. History and stats 2004 : Start of OSM 2012 : Users : + 1,000,000 Nodes : + 1,800,000,000 Ways : + 170,000,000
- 4. Community : State of the Map
- 5. Community : Mapping Parties
- 6. Wiki
- 8. IRC
- 9. Forum
- 10. Governance The ecosystem of the OSM community Citizens Associations Local governments NGOs International Organizations (UN, WB) Academia Private actors: • Google, Microsoft, Foursquare • AND • Cloudmade, Geofabrik, Camptocamp & DevelopmentSeeds The growth of the OSM project is fostered by • OpenStreetMap Foundation & local Chapters (France, Spain) • Humanitarian OpenStreetMap Team (HOT) Hum/Dev contexts
- 11. Contributing : Tracing over imagery Free, purchased, negociated
- 12. Contributing : Survey
- 13. Contributing : Data imports : Public Domain
- 14. Data primitives Node : basic element Latitude & longitude Used for POIs Way : ordered interconnection of nodes Used for linear features Closed Way : first and last nodes of the way identical Used for areas Relation : group of any primitives with associated roles Used for relationships between objects and abstract objects
- 15. Tags/attributes • Tagging system fully flexible • Strongly recommended to use the already existing, debated, approved and described tags so that the OSM data remains consolidated as much as possible. • Wiki : http://wiki.openstreetmap.org/wiki/Map_Features
- 16. Web maps : ITO http://www.itoworld.com/map/main
- 17. Walking Papers http://walking-papers.org/ • Combined, GPS and Walking Papers can be used for rapid surveying and ground truthing. • Walking Papers allow users to print out small sections of the OSM map. In the field, these paper maps can be used to draw new features, annotate existing data, and take notes that will help with the import of GPS data. • Icons in each of the corners and a unique code for each Walking Paper let users scan the paper and upload to OSM so the notes can be viewed in an editing environment.

- 26. Quality Muki Haklay (UCL) : positionning accuracy • United Kingdom: OSM - Ordnance Survey Meridian II database • Haiti: OSM - GoogleMapMaker - MINUSTAH/CNIGS 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 OS .
