Abstract

Spatial in-situ measurements of spectral remote sensing reflectance for the validation of optical satellite data over inland water bodies are usually carried out from boats or ships, where hull, superstructures and crew have an unknown influence on the results. Drift, caused by wind and currents, makes it impossible to stay precisely at the same position or to keep a constant geometry when gathering series of measurements. We developed a low-profile, remotely or autonomously operated vehicle which is capable of holding or changing both position and orientation independently. For the validation of optical satellite data and its derivates (e.g. satellite derived bathymetry), it can be equipped with a multiplexed spectrometer system, a winch with a profiler, an echosounder, or with an underwater camera system for the two- or three-dimensional mapping of shallow water areas. Its capability of keeping a constant position during the change of orientation also allows for automated BRDF studies.
