User-generated geospatial content; Volunteered geographic information (VGI)


The crowdsourcing of geographic information addresses the collection of geospatial data contributed by non-expert users and the aggregation of these data into meaningful geospatial datasets. While crowdsourcing generally implies a coordinated bottom-up grassroots effort to contribute information, in the context of geospatial data, the term volunteered geographic information (VGI) specifically refers to a dedicated collection effort inviting non-expert users to contribute. A prominent example here is the OpenStreetMap effort focusing on map datasets. Crowdsourcing geospatial data is an evolving research area that covers efforts ranging from mining GPS tracking data to using social media content to profile population dynamics.

Historical Background

With the proliferation of the Internet as the primary medium for data publishing and information exchange, we have seen an explosion in the amount...
