Usability of VGI in Haiti earthquake response - preliminary thoughts Presentation Transcript

  • 1. Usability of VGI in Haiti earthquake response Dr Muki Haklay Department of Civil, Environmental and Geomatic Engineering, UCL m.haklay@ucl.ac.uk
  • 2. Haiti http://www.vimeo.com/9182869
  • 3. Humanitarian OpenStreetMap Team • With the leadership of Mikel Maron, a Humanitarian OSM Team (H.O.T) established in early 2009 • During 2009, carried out specific mapping Gaza, Iran, the Philippines and Kenya • At the beginning of January 2010, the list included about 30 volunteers
  • 4. Haiti earthquake response • As soon as the scale of the crisis became clear, H.O.T started looking for data that is available and suitable for OSM licensing scheme: – Maps from the University of Texas – High resolution imagery in Yahoo! – UN Joint Logistics Centre data
  • 5. Activating the community
  • 6. Coordination
  • 7. Dissemination
  • 8. Understanding requirements
  • 9. Sourcing up to date imagery
  • 10. Mapping process • The OSM Wiki was used to set tasks, explain the process to new users, etc.
  • 11. Google Map Maker effort
  • 12. Activation
  • 13. Data sources
  • 14. OpenStreetMap and Google Map Maker comparison – 18th January
  • 15. OpenStreetMap and the UN MINUSTAH comparison
  • 16. Issues 1: Metadata • GeoCommons provided a portal for GI • But the details are basic: – Metadata Version: 0.1 – Title: Roads in Port Au Prince: data from United Nations MINUSTAH – Citation: MINUSTAH (United Nations Stabilization Mission in Haiti) GIS and UN Cartographic Section Theme – Keywords: haiti,port au prince,roads Place – Keywords: [not yet implemented] – Abstract:The poly shapefile show locations of major roads, arterials in Haiti's capital Port Au Prince. – Originator: MINUSTAH (United Nations Stabilization Mission in Haiti) GIS and UN Cartographic Section – Contact Person: Alice Chow – Contact Address: Alice Chow Chief, Geographic Operations Unit Cartographic Section, SSS/LSD/DFS United Nations Headquarters 380 Madison Avenue, Room M-12001C New York, NY 10017 tel. 1-212-963-5001 fax. 1-212-963-3742 chowa@un.org – Contact Phone: 1-212-963-5001 – Time Period of Content: 2010-01-16 17:00:00 UTC – Format Name: AVSHP,KML,CSV – Use Constraints: This data is licensed under a Creative Commons Attribution 3.0 License. http://creativecommons.org/licenses/by/3.0/
  • 17. Issues 2: Usability of formats • Online – WMS, tile servers (OSM, Google Maps) • GIS data format – Shapefiles, OSM, KML • GPS devices – Garmin • Ready to print – PDF, PNG
  • 18. Issues 3: Was it of any use? Source: Schuyler Erle Andrew Turner Source: Schuyler Erle
  • 19. Issues 4: Schema UN MINUSTAH
  • 20. Issues 4: Schema Google Map Maker
  • 21. Issues 4: Schema OpenStreetMap
  • 22. Issues 5: Licensing • Sean Wohltman (Google): ’As it stands right now, even though the MapMaker data is free for non-profit use, projects like OSM can't use the data because there are commercial uses for OSM and the data belongs to Google, not OSM.’ • Sean Gorman (GeoCommons): ‘Google restricts use, so we or anyone else can't remix and repurpose the data... OSM's ODBL license is viral which makes it tough for companies like Google to get it past their lawyers.’ • Mikel Maron (H.O.T): ‘I disagree with the assumption of Google’s position that the OSM license prevents community use of this data … rather it only prevents Google participating in that community, by their own choice.’
  • 23. Issue 6: Conflation
  • 24. Issue 7: Coordination • Map Action: ‘There is all these spontaneous work by people - analysing data, impact analysis initiatives, new mapping portals emerging and duplicating the same information... This cloud creates difficulties. It generates noise – The traffic on the crisismappers mailing list blocked the internet connection to the people in Haiti, with too many messages ...’
  • 25. Conclusions • VGI can be useful in emergency situation • Studying emergency case studies bring in some of the core issues of VGI: data sources, coordination within volunteering community and with responders • Some of the most powerful formats are the widely use ones, and the ability to just print a good map • Possible research direction: – Rapid conflation – Data structure that are useful for first responders
