Meta representation 23/4D

A new representation scheme for 3D building modeling to be used in digital landscape models is to be developed and investigated. It is expected to overcome some of the drawbacks of currently used 2.5D representations. Goal is a meta representation (23/4D) for storage of 3D information with the following features:

We propose a representation based on ''Singular Valued Polygon Map'' [MolenaarMolenaar1989] extended by 3D attributes. It is a special case of the boundary representation used in CAD systems. It will, however, not been possible to represent holes with this scheme.
