Usability of VGI for validation of land cover maps [PDF]
International Journal of Geographical Information Science, 2015 Volunteered Geographic Information (VGI) represents a growing source of potentially valuable data for many applications, including land cover map validation. It is still an emerging field and many different approaches can be used to take value from VGI, but also many pros and cons are related to its use. Therefore, since it is timely to get an overview
