The scientific community has and will witness a significant increase in the availability of different global satellite derived biophysical data sets. However, the use of such data is currently not supported by accurate in-situ biophysical measurements in both a research and operational context for the monitoring of forest and land dynamics. Terrestrial LiDAR (LIght Detection and Ranging) is a ground-based remote sensing technique that can retrieve the 3D vegetation structure in high detail.
Research within the Laboratory of Geo-Information Science and Remote Sensing is focused on:
- Deriving biophysical parameters to support forest inventory
- Quantifying biomass and changes in biomass
- Combining LiDAR and radiative transfer models to validate air/spaceborne data
- RIEGL VZ-400 laser scanner (Data sheet & Documentation)
- Scanner mount for manual tilt (adjustable in steps of 15° up to 90°)
- Integrated digital compass and GPS antenna
- Full waveform (FWF) readout
- NIKON D700 digital camera on high precision camera mount (NIKKOR 14/2.8 lens and NIKKOR 85/1.8 lens)
Available terrestrial LiDAR datasets
The listed datasets were collected by the Laboratory of Geo-Information Science and Remote Sensing. Reference data (e.g. forest inventory, hemispherical photography) and additional airborne/spaceborne data are available for most datasets.
