Map queries and foot traffic. Spatial layout of Shopping Malls I (A) and II (D). The number of people searching for Shopping Malls I (B) and II (E) on Baidu Maps and foot traffic for each place. Scatter plots of map queries and foot traffic for Shopping Malls I (C) and II (F). In both cases, the map query data were highly correlated with the offline foot traffic data, with both showing cyclical patterns in which they peaked on weekends. Maps were created using Adobe Illustrator, and the remote sensing images were derived from Baidu Maps.
