Querying VGI by semantic enrichment
, 2016 Volunteered geographic information (VGI) plays an increasing role in current geodata provision. At the same time, due to its lack of structure, it is hard to use as meaningful input in software applications. In this chapter, we embark upon the unstructured character of VGI and on ways to enrich the structure in order to make it suitable for information

A representativeness-directed approach to mitigate spatial bias in VGI for the predictive mapping of geographic phenomena [PDF]
International Journal of Geographical Information Science, 2019 Volunteered geographic information (VGI) contains valuable field observations that represent the spatial distribution of geographic phenomena. As such, it has the potential to provide regularly updated low-cost field samples for predictively mapping the ...

ISPRS International Journal of Geo-Information, 2021 One of the most important challenges of volunteered geographic information (VGI) is the quality assessment. Existing methods of VGI quality assessment, either assess the quality by comparing a reference map with the VGI map or deriving the quality from ...
