Laserscannersysteme für geowissenschaftliche Vermessungszwecke
Set von Laserscannersystemen für geowissenschaftliche Vermessungszwecke (Fernerkundung), bestehend aus zwei Laserscannersystemen (UAV-LS) für mobile/Drohnen/unbesetzte Luftfahrzeuge und einem terrestrischen Laserscanner (TLS).
Potsdam
Die Sektion 1.4 Fernerkundung und Geoinformatik des GFZ Potsdam beabsichtigt, eine Reihe von vermessungstauglichen Laserscannersystemen zu erwerben, die aus zwei Laserscannersystemen für mobile/Drohnen/unbesetzte Luftfahrzeuge (UAV-LS) und einem terrestrischen Laserscanner (TLS) bestehen.
In general, these systems are intended to collect very detailed three-dimensional information on vegetation and Earth-surface structure at the centimeter scale. The systems are expected to be easy to integrate, e.g. by using same or similar software processing workflows and laser wavelengths. All systems are expected to deliver multiple returns per fired pulse to optimize sampling in dense vegetation. Additionally, all systems need to be fully integrated (turn-key) solutions in order to allow fast adoption for scientific data collection.
The first UAV-LS should have the ranging capabilities to be mounted both on (low flying) manned as well as unmanned aircraft/UAVs. For the other UAV-LS system, it will suffice to be mounted on a UAV flying under typical conditions as prescribed in European countries (maximum altitude of 400 feet above ground level). Both these UAV-LS systems should be light-weight (<5 kg) with a high measurement rate to allow optimal mapping times and productivity. Furthermore, the UAV-LS systems will be expected to deliver high-quality position of the data through integration of high-quality Inertial Measurement Units (IMU) and the use of either Real-time kinematic (RTK) or Post-processing kinematic (PPK) technology.
The terrestrial laser scanner (TLS) will be used to produce reference point clouds and products for the UAV-LS systems. The TLS should be light-weight (<10 kg), and allow direct geo-referencing of point clouds via RTK or PPK. Optimally, the TLS will be interoperable with TLS systems used in ongoing activities on calibration and validation data collection for forest above-ground biomass (Calders et al., 2017; Duncanson et al., 2021).
