Physical Geodesy and National Geodetic Surveying

Abstract

Evolution of the Swiss national geodetic survey, horizontal and vertical networks. Global and local reference systems and frames. Spherical and ellipsoidal calulations, projection systems, datum transformations, height systems. Basics on physical and astronomical geodesy, geoid determination. New national geodetic surveys LV95 and LHN95. Modern satellite based networks and on-line services.

Objective

Basic knowledge of the theory and evolution of the Swiss National Geodetic Survey.

Content

An important part of the lecture focusses on the history and evolution of the traditional Swiss national geodetic survey in terms of the horizontal as well as the vertical (height)-networks. Furthermore the lecture illuminates the impact of recent space geodetic techniques on the national geodetic survey: Global and local refernce systems and their realisations (reference frames), spherical and ellipsoidal calulations, projection systems, datum transformations, classical triangulations, height systems, 3D-networks, basics on physical and astronomical geodesy, geoid determination. New national geodetic survey LV95, new height system LHN95. Modern satellite based networks and on-line services for navigation and positioning.
