The Danish cadastre of tomorrow

The digitalization of the Danish cadastral system has in recent years expanded the usability of the system. The cadastral system has evolved from being a somewhat “closed” register containing information about ownership and restrictions on property to being an “open” platform for multiple purposes, for instance reference for visualization in Geographic Information Systems. This multifunctional use of the cadastral system urges the need of rethinking the role of the cadastral system. Furthermore there are some obvious problems within the Danish cadastral system that needs to be addressed: Some objects are not conclusive (leasehold property) and some objects cannot be identified in the cadastre (flats, houseboats). Perhaps a 3D-cadastre is called upon to solve these problems. Another problem is that the cadastral map is a juridical map, where the absolute accuracy has not been an issue of importance. The fact that the map is now widely used as a reference for data-presentation makes the relative accuracy a problem. The cadastral map also has some imperfections in regard of lacking objects. The main questions are: Which role is the cadastral system going to play in the future? How is the interaction with other registers going to be? Which information is stored where and how (object-types and relations)?
