The purpose of this paper is to analyze the feasibility of using this source of spatial information for three use cases related to land cover: Calibration, validation and verification. We first provide an inventory of the metadata that are collected with geo-tagged photographs and then consider what elements would be essential, desirable, or unnecessary for the aforementioned use cases. Geo-tagged photographs were then extracted from Flickr, Panoramio and Geograph for an area of London, UK, and classified based on their usefulness for land cover mapping including an analysis of the accompanying metadata. Finally, we discuss protocols for geo-tagged photographs for use of VGI in relation to land cover applications. 2016 10.3390/ijgi5050064 276 98 public ISPRS International Journal of Geo-Information 5 5 e64 TRUE 2220-9964 Harnessing the power of crowdsourcing to improve land cover and land-use information (CROWDLAND, FP7 617754) Geo-Wiki FALSE yes info:eu-repo/grantAgreement/EC/FP7/617754/EU/Harnessing the power of crowdsourcing to improve land cover and land-use information/CROWDLAND info:eu-repo/semantics/article info:eu-repo/semantics/openAccess
