Ten years ago, the Geobasis Steering Committee (LA Geobasis) was established to implement the strategic and fundamental Objectives of the Working Committee of the Surveying Authorities of the Laender of the Federal Republic of Germany (AdV). It is based on an administrative agreement between the 16 regional surveying and mapping authorities of Germany relating to the cooperation in official surveying. In particular, the Committee accompanies the work of the three central offices in the fields of satellite positioning data, house coordinates/house surrounds/3D data as well as geotopographic data. In addition, the main focus is on the joint implementation of transnational projects and procedural developments. The sustainable financing and controlling of institutions and projects is ensured by a central Agency. Flexibility and commitment characterize the work of the LA Geobasis and ensure effective task completion within the federal framework. Cooperation with the Cartographic and Geodetic Authority of Germany (BKG) is indispensable. The LA Geobasis has proven itself in the official surveying system as a successful model for the cooperation of the regional surveying and mapping authorities among themselves and with the federal government.
