Further application fields could be entered, if distributed spatial objects could be integrated on the fly into one 3d scene. We argue, that this integration can only be successful

In this article we sketch promising new applications and examine their technical requirements. We discuss how these issues can be addressed by the use of interoperable geo web servic

To overcome current limitations we introduce a new web service for the 3d visualization of spatial data. The presented application scenarios

Besides the well-known applications in the fields of architecture,urban and transport planning, surveying and mobile telecommunication, 3d models become increasingly important in the fields of city and regional marketing (e.g. representation of regions,municipalities

Most applic

E.g. an architecture firm requires for the planning of a new shopping mall digital 3d geoinformation in terms of a small scaled and low detailed city model covering the whole planning area, which will support the identification of appropriate locations. The 3d objects also have to be related to socioeconomical 2d geoinformation. When the appropriate location has been found, detailed
