An approach is provided for generating accurate and substantially real-time map and location-based data in a cost-effective manner. Specifically, one or more communications within one or more social networks are monitored, processed, and mined to determine map-related information (e.g., maps, traffic, points of interest). The map-related information is then subjected to one or more threshold criteria (e.g., a correctness probability, a level of confidence, a degree of trust, an author's influence, a rating, or a combination thereof) to better ensure its accuracy before being made available to mapping and/or location-based services that can use the map-related information to develop better quality maps and/or location-based mobile applications (e.g., improved routing guidance, location recommendations, etc.). By providing mapping and location-based services with accurate and real-time map and location-based data, the services can fulfill user's increasing expectation and demand for up-to-the-minute information.
