OpenStreetMap : Sahana Mapping Client (SahanaCamp 1.2)
- 1. OpenStreetMap: SahanaMapping Client 2 November 2010, Sahana Camp Fran Boon fran@sahanafoundation.org
- 2. Mapping • Overlay • Import • Export …including Offline…
- 4. OpenStreetMap • “Wikipedia of Maps” • Collaboratively-edited: Participatory Mapping • Free-form tagging
- 5. What about Google? • Restrictive License – Images only – no source Vectors – Cannot access Offline • Only covers the areas of commercial interest to Google • Cannot develop new tags / rendering • Doesn’t respond fast enough in the event of a Disaster
- 9. Haiti • High-resolution Satellite Imagery available quickly (26 hrs) • OpenStreetMap volunteers used this & old printed maps to quickly cover Port-au-Prince • These were made available as basemaps on handheld GPS
- 12. Humanitarian • HOT: Humanitarian OpenStreetMap Team available for Tracing & Field Deployments (focus on Training) – Kibera slum, Nairobi – Haiti – Philippines • Humanitarian Data Model
- 13. Offlineusage Garmin Android iPhone •Local Server – Performance – Save bandwidth costs (e.g. Satellite, such as BGAN)
- 14. Walking Papers • Print a map of current status • Draw on this map • Scan Map in • Upload • Trace over it
- 16. End

- “Location, Location, Location” “Everything is related to everything else, but near things are more related than distant things.“ - The First Law of Geography http://en.wikipedia.org/wiki/Tobler%27s_first_law_of_geography
- Display WMS, KML & Internal Resources over an OpenStreetMap base layer (or Google, or Yahoo)
- Just like Wikipedia, the power of crowd-sourcing for creating Accurate, up-to-date content is incredible. The fact that anyone can edit would seem to suggest that the data will be unreliable, but actually the opposite turns out to be true – there are more honest people than vandals. Not having a hard system of classification allows it to adapt rapidly which is especially useful for Local contexts. This doesn’t mean that there is anarchy – using agreed tags means that the various rendering engines will display them properly.

- Jalalabad…nothing there is there?
- Wrong! This is a significant place…
- Yahoo are just as bad…
- As are Microsoft…
- But OpenStreetMap has a lot more :)
- Google has pretty good coverage of Port au Prince…
- …however OpenStreetMap is better & has the Damage Layer available. (It is also routable & had information on the blocked roads)

- Seems to be an active community (especially Urban). Mapping Party held in 2009 Domain openstreetmap.org.vn : Available (could setup a local server which would be faster for local users)
