Abstract
In the surveying of waters, especially the
geometrical information about the morphologic-topographical structure
of any kind of offshore and inshore waters is recorded. This is
necessary for giving detailed information e.g. for the safety use of
the rivers, canals and coastal waterways by trade vessels or tourist
ships.
The paper describes which measuring systems and
surveying systems are used for these geodetic tasks with an impression
of their reachable accuracies. By this, the use of modern multi
channel and multi beam echo sounding systems are explained. For the
part of positioning, the change from microwave radio location systems
to location and navigation with Global Positioning System (GPS) is
presented.
The examples are taken from daily practice at
Federal Waterways in the Federal Republic of Germany (FRG). The author
is Head of the Department Geodesy at the Federal Institute of
Hydrology (FIH). The main tasks in Geodesy at FIH are research and
development of new systems and methods for surveying of waters, so
that the personnel of the Federal Waterways and Shipping
Administration (FWSA) is able to optimise their monitoring - specially
the water depths - of the Federal Waterways in FRG.
In connection to these tasks the geodetic survey
offices of the 16 Federal Counties of FRG and the FWSA are
co-operating in the field of GPS permanent reference stations. The
Satellite Positioning Service (SAPOS HEPS) is used for high precise
coordinates as results by regularly surveying of waters.
