Alkis — Recording points with measurement

The locally marketed recording points, managed in the Official Property Register Information System (ALKIS), as well as the digital satellite positioning service SAPOS refer to the official spatial reference. The network of recording points, marketed as floor/wall points, is no longer renewed after the productive introduction of SAPOS since 2005 in case of loss or damage, but is still available for use. A guarantee for the local presence of points registered here cannot be assumed. Lost points are removed annually from the evidence. * Important note on how to handle surveying marks: Surveying marks for marking points of the location field may only be introduced, altered, restored or eliminated by surveying points (these are the state’s Geoinformation and Surveying and Surveying Engineers approved in Hamburg!
