This distance elearning course will cover a number of airborne lidar technologies including multi-spectral, single photon, topo-bathy and UAV.
Dr. Gottfried Mandlburger, TU Vienna, Department of Geodesy and Geoinformation (Austria)
Target audience: Staff of national mapping agencies, public authorities, private companies,
and PhD students with interest in small and large scale airborne laser scanning
Preconditions: Familiarity with the basic concepts of Airborne Laser Scanning
Maximum number of participants: 40
Course objectives: The recent decade has brought tremendous progress in Airborne Laser
Scanning (ALS), the state-of-the technique for 3D mapping of topography and shallow water
bathymetry. The pulse repetition rates increased from the kHz to MHz level and, together
with the introduction of single photon sensitive receiver arrays, this boosted both the
achievable point density and area coverage performance. LiDAR point cloud classification
further profited from multi-spectral laser scanning using infrared and green wavelengths and
from concurrent capturing of image and scan provided by modern hybrid sensor systems.
Green lasers are used for measuring underwater topography, also referred to as bathymetry,
laser bathymetry. Airborne Laser Bathymetry is no longer restricted to charting shallow
coastal areas only but evolved to a powerful tool for high resolution mapping of the entire
littoral area, referred to as topo-bathymetric LiDAR. Finally, sensor miniaturization and
progress in aviation technology has opened new close-range airborne applications due to
integration of lightweight LiDAR sensors on Unmanned Aerial Vehicles. All these topics are
covered in the EuroSDR distance course “Recent LiDAR technologies”.
In this course, the participants will refresh the basics of ALS, will learn details about the
above mentioned technologies in theory, and will also process provided sample data in
hands-on sessions. For the theory part of the course, respective papers, text book excerpts,
and slides will be provided along with short pre-recorded videos. The scientific laser
scanning software OPALS is the basis for practical data processing. The participants obtain
a temporal personal scientific license in advance, so that they can already familiarize
themselves with the software before the actual start of the course. The examination consists
of multiple choice tests (theory) and short technical reports (exercises).The course is divided
into the following six modules.
