VGI as a Compilation Tool for Navigation Map Databases

Volunteered geographic information, a crowdsourced approach to gathering geographic information, is being used in numerous map database compilation systems. Active and passive contribution systems exist, but it is the active systems, through which contributors can provide their personal local knowledge, that hold the greatest promise for improving the quality of spatial databases used for navigation and location-based services. Both open and hybrid map compilation systems have been developed in an attempt to benefit from VGI. We discuss the nature, limitations, and advantages of a range of crowdsourced compilation systems in an attempt to evaluate the influence of VGI in helping to improve various aspects of data quality.
