Digital geodetic archive
Alfredsson, Anders & Mikael Lilje
Since several years, Lantmmteriet (the National Land Survey of Sweden) has worked with the process to convert the analogue information regarding the points in our national geodetic networks to digital format. These networks are under the responsibility of Lantmmteriet. It is important to have a homogenous archive about the geodetic points. It is also important that the data is easily accessible. Measurements and adjustments belonging to the national 3D, horizontal, vertical and gravimetric networks are stored in a systematic way in the archive. The Geodetic Archive at Lantmmteriet does not have any information about local networks that belongs to the municipalities. Traditionally the different national geodetic networks have had their own archive separate from the others even though many points are physically the same in the various networks. It is even so that the same point may have several different point identifiers depending on what network it belongs to. Converting towards a digital geodetic archive means that we have been forced to merge the different datasets into one common database to make the use of the geodetic archive more efficient. A digital geodetic archive has been in place for the staff at the geodetic archive for some years but we are now making it accessible for other users through the Internet. We hope that this will help them to find the information by themselves. It will improve the efficiency of the geodetic archive as well as the archive will be available 24 hours per day any day of the year.
