Assessing semantic information of Volunteered Geographic Information

Although high quality geospatial information is in great demand but limited due to short supply, OpenSteetMap (OSM) is striving hard to compete with the commercial vendors providing worldwide map data-sets free of cost. The users can now contribute to fine cartographic mapping and enrich it with attribute details. This area was traditionally limited to professionals and expert cartographers further imposing technical and legal restrictions over its access to end-users(Haklay and Weber, 2008).
