Integration of spatial information for geo-information systems
This book presents a model for the integration of spatial information for 3D Geo-Information Systems (3D-GISs). Former Geo-Information Systems are restricted to 2D space. They execute the integration of spatial information by conversion of vector and raster representations. This, however, leads to conceptual difficulties because of the totally different paradigms. After an introduction to the history and architecture of Geo-Information Systems this book examines spatial representations in 2D and 3D space regarding their suitability in 3D-GISs. A three-level notion of space serves as a basis of a model for the integration of spatial information. It likewise takes into account the geometry, metrics and the topology of geo-objects.
