Geodesy and Geoinformation: What's that?
The main application fields of surveying engineering are situated as well in civil engineering as in mechanical engineering and plant construction. Steering and quality assurance of complex construction and production processes require the supply of high precision geometrical information concerning the actual state of the process components. Practical examples for the participation in construction pocesses are e.g. steering of road heading machines in tunneling, stability control of buildings and geotechnical objects and the precise setting out of bridges and high-speed railroads. In the area of industrial production, quality control in automotive and aviation industry represent important fields of activity. Using high-tech measurement systems like robot tacheometers, laserscanners and lasertrackers, surveying engineering captures and evaluates all relevant informations in real-time. It attends the full process, beginning with the planning phase, via the technical realisation up to continuative monitoring for control and avoidance of possible damages. Engineering geodesists are all-round experts, who develop tailor-made solutions for metrological problems in dynamical environments.
There are various fields of activity for engineering geodesists. The area of civil engineering includes the creation of detailed topographical plans as precondition for planning processes, the creation of high precision engineering networks for the realisation of constructions, all surveying activities on the construction sites and the construction monitoring for damage prevention respectively the explanation of possible reasons. Especially the last task significantly exceeds normal surveying and requires detailed deformation anlyses and interpretations which are realised by the cooperation with civil engineers, geotechnicians, geologists and geophysicists. In this respect, surveying engineering is strongly embedded in the development of early warning systems. The area of industrial surveying includes the development, calibration and application of mechanical, optical and electro-optical measurement systems with high-frequency measuring rates (partly several thousands of measurements per second), extreme precision (partly within the range of some μm) and a high degree of automation. The measurement systems are fully integrated in industrial production processes and provide the geometrical information for quality control of the products (e.g. shape control of vehicle components). Industrial surveying is also involved in planning, precise setting out and control of technical plants. This can be all kinds of manufacturing plants but also power plants (e.g. wind or hydroelectric power stations) and research institutions like particle accelerators.
Consequently surveying engineering is a very interdisciplinary science. Engineering geode-sists are working close together with civil engineers, geologists and geotechnicians, geophysicists, mechanical and electrical engineers. Besides geodetic knowledge, this cooperation also requires multidisciplinary competence and a high degree of social and communicative skills. Engineering geodesists are not only surveyors but also participate in the steering of complex construction and production processes.
