Urban planners, architects and drivers are based on two-dimensional maps, which they sometimes much imagination demands and can lead to wrong conclusions. "Three-dimensional models provide a striking contrast image and be better understood, because they tend to conform to the natural human sense of space," says Jorg Haist, head of 3D Geo Information Systems at the Fraunhofer Institute for Computer Graphics (IGD).
HB BERLIN. For architects, planners and project developers based on the spatial visualization of 3D city models, GIS has several advantages: it is even possible the transmission of sound between buildings and shading to check for new building - features which, in spite of all the other calculations are often detected only after completion. Even local residents can get through a planning approval procedure, a glimpse of how their city walk around with a new mall will be. Brokers and marketers are equipped with location of 3D GIS models of intuitive arguments.
So that they can get better and easier to use, the Fraunhofer-IGD the so-called "CityServer3D developed, which allows an interactive, three-dimensional visualization of geospatial data and mobile. Install Unlike conventional solutions to the user on their computer software needs, the data can now be viewed with any browser anywhere, provided that the Java plug-in 3-D includes "promises Haist.
The 3D spatial data server accesses several database systems and formats. "With him geometries can be saved as well as their topology, materials, factual information and addresses," explains the Fraunhofer researchers. Geographic nodes and edges and surfaces of the objects are broken down and stored in tables, so that even very complex architectural models can be managed. All data are accessible via different interfaces. Conversely, various information sources can be brought in, without causing compatibility problems. That is not insignificant, since the data collection and conversion still makes up two thirds of the cost of geo-information systems.
