This book collects innovative research presented at the 17th Conference of the Association of Geographic Information Laboratories for Europe (AGILE) on Geographic Information Science, held in 2014 in Castellón, Spain. The scientific papers cover a variety of fundamental research topics as well as applied research in Geospatial Information Science, including measuring spatiotemporal phenomena, crowdsourcing and VGI, geosensor networks, indoor navigation, spatiotemporal analysis, modeling and visualization, spatiotemporal decision support, digital earth and spatial information infrastructures.
The book is intended for researchers, practitioners, and students working in various fields and disciplines related to Geospatial Information Science and technology.
