This e-book offers a version for the mixing of spatial details for 3D Geo-Information platforms (3D-GISs). Former Geo-Information structures are constrained to second house. They execute the mixing of spatial info by means of conversion of vector and raster representations. This, although, results in conceptual problems as a result of the completely different paradigms. After an creation to the background and structure of Geo-Information platforms this booklet examines spatial representations in second and 3D house concerning their suitability in 3D-GISs. A three-level proposal of area serves as a foundation of a version for the mixing of spatial info. It likewise takes under consideration the geometry, metrics and the topology of geo-objects.
