Exploring Geotagged images for land-use classification

On-line photo sharing websites such as Flickr not only allow users to share their precious memories with others, they also act as a repository of all kinds of information carried by their photos and tags. In this work, we investigate the problem of geographic discovery, particularly land-use classification, through crowdsourcing of geographic information from Flickr's geotagged photo collections. Our results show that the visual information contained in these photo collections enables us to classify three types of land-use classes on two university campuses. We also show that text entries accompanying these photos are informative for geographic discovery.
