The mobile use of measurement systems is becoming increasingly important in many areas of application. In particular, the use of such systems on flying platforms (civilian drones) is increasingly becoming the standard for surveying buildings, forests and agricultural areas. This project focuses on surveying the shore areas of lakes, rivers and the transition area from land to water. This enables critical infrastructure elements such as pipelines, supply lines and dams to be recorded and monitored and their operational safety to be guaranteed. The fully functional demonstrator from the LZN demonstrator project SwInG will be equipped with a green laser for this task, thus creating a bathymetry system. This will make it possible to penetrate the water column and record the topography below the water level. The challenge of the project is not to increase the weight of the already constructed demonstrator. This is the unique selling point of the Swing 4.0 system. A bathymetry system with a total weight in this size and weight class is not yet available on the market. The innovation of using special algorithms for data evaluation to record both the water level and objects in the water with just one measurement sets new standards. The demonstrator's already very broad range of applications is thus further expanded. The aim is to enable applications for recording natural surfaces and terrain, such as lakes and rivers, as well as monitoring anthropogenic structures such as pipelines, dams or rainwater retention basins.
