With a growing ability to collect and store geospatial information leading to increasing amounts of heterogeneous geospatial data, Next Generation Geospatial Information confronts these new challenges through a collection of contributions from leading experts. This book addresses the distributed nature of currently available spatial data infrastructure. It discusses image-based geospatial information management and modeling, covering such topics as semi-automated feature extraction. It presents indexing techniques and query processing methods including indexing for location-based services. This text also explores the role of ontology and semantics in geospatial data processing.
