4D Land Administration Solutions in the Context of the Spatial Information Infrastructure (original) (raw)

SUMMARY The increasing complexity of modern world requires that Land Administration (LA) systems need an improved capacity to manage the third dimension. As the world is per definition not static, this implies that we must handle the temporal (forth) dimension as well, either integrated with the spatial dimensions or as separate attribute(s). Several important types of LA objects can be considered in a 3D+time (4D) context; for example apartments and utility networks. Currently individual apartments are usually not visible on the cadastral map, only the outline of the building is visible. However, the individual rights are attached to the individual apartments. Often it is possible to access (analogue or digital) drawings of the apartment building showing the individual units. But this is not integrated with the cadastral map. However, the building registration in more and more countries is geo-referenced and contains in some cases the 3D spatial description of apartment units to wh...
