State Office for Surveying and Geoinformation Thuringia

from Wikipedia, the free encyclopedia

On April 1, 2005, the Thuringian land surveying office and the Thuringian land registry offices were organizationally combined to form the State Office for Surveying and Geoinformation (TLVermGeo). The previous surveying offices were divided into eight cadastral areas with offices and form the department "Parcel-related geographic reference data ". They will remain as decentralized offices at the previous locations. Only the place of work in Mühlhausen has been moved to Leinefelde-Worbis.

Geographic information

Both the Geoinformationszentrum (GIZ) and the state aerial image archive - both in Erfurt - provide information about the products of the surveying office. Extracts from the real estate cadastre and information on other services can be obtained from the information offices in the cadastral areas .

Land survey

The former state survey office was organized in a similar way to other German federal states. The national survey itself has the usual form of modern fixed point networks : first-order points ( TP ) at approx. 30 km intervals, compression by second to fourth-order points, comprehensive basic network using dGPS . The network and the geoid determination are integrated in the German basic network DHDN .

The first precise land survey was carried out from 1803 on behalf of Prussia by the Gotha observatory director, the Austrian astronomer Franz Xaver von Zach . In the course of this, Zach's method with powder flash signals was used for the first time , which proved to be very economical. The survey network was - as elsewhere in Europe - revised every few decades and now has an accuracy in the cm range.
