Implementation of new reference systems in Denmark
Bahl, Lola
In year 2000 new reference systems for horizontal coordinates (UTM/ETRS89) and heights (DVR90) were defined. For 5-6 years National survey and Cadastre (KMS) has coordinated the implementation of the new reference system in all existing geographical data. Governmental authorities, municipalities and the private sector have transformed large amount of data from the old systems to the new ones. This year the cadastre map will be transformed to the UTM/ETRS89. By the end of 2006 it is expected that 75% of the horizontal data in the municipalities has been transformed to UTM/ETRS89. One of the central elements for making this implementation project a success is the accessibility of transformation programs. The transformation procedure between the old systems and UTM/ETRS89 is rather complex, as it cannot be described with a set of parameters. In the beginning of the implementation project, no Geographical Information (GI) systems handled the Danish transformation procedures as a standard. Today all GI systems and GPS systems have built in the official transformation procedures which can be downloaded free of charge. The implementation process and experiences from the process, which is long and deadline free, is described.
