Openstreetmap is a collaborative project to create a free editable map of the world. Participants can contribute data from aerial imagery, field work, or other sources under open licenses. Volunteers are waiting to trace roads, buildings and other features from aerial photos to quickly create vector maps. Field data on land use, names, and points of interest are also needed. Any data shared must be in an open format like shapefile and avoid copyrighted sources. People with local knowledge or access to data are encouraged to request imagery from partners or contribute what they collect to improve Openstreetmap maps.

2. What OpenStreetMap needs

3. Aerial imagery
● Lots of people from OSM are waiting for one
thing : tracing over aerial imagery !
● Identifiable data : roads, landuse, high
structures, damaged buildings...
● Rather fast to get vector data from these
images

4. Example : Kyrgyzstan

5. Field data
● People on the ground often needed for specific
data :
● Landuse and roads
● Street names
● Points of interest (health facilities, education,
infrastructures...)
● Formats :
● shapefile is the best
● other possibilities : kml, gpx, pictures, sketches by
hand...

6. Licence questions

7. Aerial imagery
License agreement to allow data tracing for OSM
Two methods :
● Public WMS, available for anyone to use (eg
Haiti)
● Private WMS, available on request for people
interested in tracing (eg Kyrgyzstan, Gaza)

8. Points of interest
● Personal knowledge of the reality
● Public domain data
● No licensed data like copyrighted paper maps
or Google Maps
● Example : you collect data with a GPS and then
share it with OSM

9. Please ask !

10. Scenario
You want a map You have a map !
No vector data OSM shapefiles
available available
You share
your data
Data
integration
OSM creates
data

11. Conclusion
OSM has dozens of people who waiting for one
thing : mapping.
We have a lot of potential data sources.
So please ask, even now, if vector data is needed
for an area !
