Can we rely on online maps?



For the companies such as Google that maintain online maps, the authoritative sources of geographic data are commercially expensive so they tend to use crowd sourced geographic data in these maps. The public is increasingly using these online maps, nevertheless, the quality and integrity of the data in the maps is not fully known as they are created by an untrained crowd. Yet, the online maps have the potential to contribute to fatal errors particularly in emergency situations. While the use of theses maps by the public is unavoidable, the development of an approach to facilitate the automatic validation of the data in these maps forms the foundation of the proposed study mission.
