A multi-scale approach to exploring urban places in geotagged photographs
We examine the spatial and thematic properties of geotagged Flickr photographs. Flickr tags were aggregated at multiple scales using hexagonal lattices. Tagging similarity was examined using odds-ratio across multiple scales. Similarity was related to scale of aggregation. Place-specific tagging was observed at local scales in the study area.
