The link between geometrical geodetic techniques (e.g. satellite positioning techniques) and physical geodetic techniques (e.g. geometric levelling combined with gravity measurements) is the geoid as a special equipotential surface of the gravity potential. There is a broad spectrum of applications of the geoid or more generaly of the gravity field, even more in the future than in the past.
Nowadays 3D Geoinformation is needede for many planning and analysis tasks. For example, 3D city and infrastructure models are paying the for complex environmental and noice analyzes. 3D geological sub-surface models are needed for reservoir exploration in the oil-gas-and geothermal industry. Thus 3D Geoinformation brings together researchers and practitioners fr9om different fields such as theā¦
