Data and metadata management for better VGI reusabillity

The rapid expansion of citizen science projects and crowdsourcing applications is yielding a huge and varied pool of volunteered geographic information (VGI) on a wide variety of themes. This VGI may be of huge value for institutions, individuals and decision makers, but only if it can be discovered, evaluated for quality and fitness-for purpose and combined with data from other sources. If VGI data is to be discovered, used and re-used to its full potential, it must be actively managed. In this chapter we assess the current state of the art regarding data management practices in VGI, identify some challenges, obstacles and best-practice examples, and review a range of developing and established open source technologies which can underpin robust and sustainable data management for VGI.
