Abstract

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.

1 See Surowiecki (2005) for an impressive essay on the “Wisdom of Crowds” and Shirky (2008) for a fascinating discussion of the crowd and its self-synchronization.

2 During his keynote address at Interactive Local Media (ILM) 2007, John Hanke, director, Google Earth and Maps for Google, while discussing the quality of the data provided by Google’s map data suppliers, looked up at the audience and said, “You have no idea how bad these data are.”

3 See David Stage (2009) for an interesting distinction between “authoritative” and “trusted” data sources. Stage considers those who collect and distribute authoritative data to be trusted.

4 See Van Exel et al. (2010), p. 3.

5 The progress of OSM in developing a crowdsourced database in the United States, a country with a rich history of publicly available, low-cost, nonproprietary spatial databases, appears to be less impressive than in other areas of the world.

6 2007 was the last year for which publicly available financial data was available for NAVTEQ. Due to its acquisition by Nokia in 2008, NAVTEQ ceased to have public responsibility to report on its financial health.
