This volume includes top papers from the 2014 International Symposium on Spatial Data Handling and covers Web and Crowd-sourcing GI, Network Analysis, Spatial Modelling and Reasoning, and Statistical and Spatial Analysis. The Symposium is the premier long-running forum in geographical information science, providing a prestigious outlet to geographers, cartographers, computer scientists and others in this rapidly developing multidisciplinary area.
