Surveying / Geodesy
Geodesy is the science of surveying and depicting the earth’s surface. Its purpose is to determine the shape of the earth (referred to as the geoid) and its gravity field, and any changes that take place. Geodetic surveying tasks include the definition of geodetic reference systems and the creation, updating and management of reference frameworks, as well as the marking and surveying of the national borders.

The fundamentals of geodesy include reference systems, the definition of reference areas and map projection systems and their realisation in the form of reference frameworks, geoid models, control and permanent GNSS networks. These are used for bringing spatial data (geodata) of all types into harmony with an unequivocal and precise geometric correlation with the European and global reference systems. Thanks to geodetic criteria and reference data for the national geodata infrastructure, it is possible to depict geodata and their national and international interchangeability in a homogeneous manner.
