Improving the map in OpenStreetMap involves data availability and reliability. Through the operations in which they are involved, organizations have a vast amount of data at their disposal, much of which is confidential and goes against the spirit of Open Data, which is all about sharing. This session will show how the OSMer in Residence program has fostered this paradigm shift through collaborati...

OpenStreetMap is a community project to map the world. Everybody can contribute whatever they want. Or can they? What are the rules that govern what can be mapped in OSM and how? How are we creating a coherent global map and not just a bunch of random data about the world? OpenStreetMap is a community project to map the world. Everybody can contribute whatever they want. Or can they? What are the...
