• Measurement system analysis and model-based sensor fusion for hydrographic water exchange zone monitoring using unmanned carrier systems

  The aim of the project "Measurement system analysis and model-based sensor fusion for hydrographic water exchange zone monitoring with unmanned carrier systems (WaMUT)", which the GIH is working on on behalf of and in cooperation with the Bundesanstalt für Gewässerkunde (BfG), is the continuous, quality-assured acquisition and modelling of geo-base data of the water exchange zones and shallow water areas of federal waterways to improve the quality of - in particular small-scale - digital terrain models of the watercourse. In contrast to the classic geodetic observation methods for recording bathymetry and topography, the use of unmanned sensor platforms - primarily on land (unmanned aerial vehicle UAV), but also on the water (unmanned surface vessel USV) - has come into focus in recent years. As part of the WaMUT project, these measurement systems are to be validated and, based on this, a quality-assured, integrated measurement programme is to be created in order to be able to record reliable geobase data in the water exchange zones.

• Risk Minimization in Structural Safty Monitoring

  One main goal of structural safety monitoring is minimizing the risk of un-expected collapses of artificial objects and geologic hazards. Behind these activities in the DFG founded project, it is the need of the society in mini-mizing the negative environmental impacts. An optimal configuration for measurement setups and all other decisions shall therefore review and ra-te the risks of an individual monitoring project. Nowadays, the methodolo-gy in many engineering disciplines and mathematically founded decisions are usually based on probabilities and significance levels but not on the risk (consequences or costs) itself.

• Simulation-based optimization of tachymetric network measurements

  In geodetic networks of large extent or with a large number of points, the tachymetric network measurement is usually associated with a high logistical effort. The individual measuring points must be visited again and again in order to align the reflectors to the current tachymeter position. The efficient planning of the measurement has the goal of causing the lowest possible costs or it aims at the shortest possible measuring duration.

• Efficiency optimization of geodetic measurement processes

  The efficiency optimization of measurement and evaluation processes of engineering geodesy requires a detailed modeling of the individual sub-steps. This modeling is realized by means of Petri nets. Thus computer-aided simulations can be carried out. To minimize the cost or duration of the measurement processes Genetic algorithms are used as an optimization method.
