µ-shapes: Delineating urban neighborhoods using volunteered geographic information
Journal of Spatial Information Science, 2016 Urban neighborhoods are a unique form of geography in that their boundaries rely on a social definition rather than a well-defined physical or administrative boundary.

Accurate attribute mapping from volunteered geographic information: issues of volunteer quantity and quality [PDF]
, 2015 Crowdsourcing is a popular means of acquiring data, but the use of such data is limited by concerns with its quality. This is evident within cartography and geographical sciences more generally, with the quality of volunteered geographic information (VGI)

Evacuation time estimate for a total pedestrian evacuation using queuing network model and volunteered geographic information [PDF]
, 2015 Estimating city evacuation time is a non-trivial problem due to the interaction between thousands of individual agents, giving rise to various collective phenomena, such as bottleneck formation, intermittent flow and stop-and-go waves.

Volunteered Geographic Information
, 2020 Volunteered geographic information (VGI) is spatial data that are gathered and shared by individuals to derive information about the world. VGI has largely been embraced due to the pervasiveness of mobile devices and affordances offered by the locational sensors that are housed within them.

VOLUNTEER GEOGRAPHIC INFORMATION IN AFRICA [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019 Abstract. During the past few years much effort has been put into developing community-based methods to capture and analyze a large amount of data in a systematic manner. This new source of geo-referenced data could be very important throughout Africa where crowd sourcing activities or volunteered geographic information (VGI) enhance participation and ...
