These carefully selected and peer-reviewed papers from the 17 th AGILE conference on geographic information science showcase some of the most advanced research in this fast-moving field, ranging from crowdsourcing to geosensor networks and indoor navigation.

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.

Based on the annual international AGILE conference and continuing a series that started in 2008 High-quality state-of-the-art research papers in the field of GI science Especially focuses on GI science and applications in the European context Reviewed by international experts Includes supplementary material: sn.pub/extras
