Soil movement, and long-term subsidence, can be measured and monitored in several ways. InSAR (Interferometric Synthetic Aperture Radar) uses radar images of the Earth taken from a satellite. LiDAR stands for Light Detection And Ranging. In this technology, laser pulses (light waves) are sent from a scanner, where the scanner is attached to a tripod, airplane, helicopter or drone.
The Dutch National Research Programme on Greenhouse Gases in Peatlands (NOBV) is researching the effectiveness of measures in the peat meadow area to reduce greenhouse gas emissions. The effects on soil subsidence are also mapped out. Among other things, InSAR and LiDAR are used for this. How do these methods work and what do we know so far about using InSAR and LiDAR to measure soil movement in the peat meadow area? This will be the topic of the webinar NOBV is organizing on April 3 from 10:00-11:30 am.
What to expect in this webinar:
- Researcher and advisor Sanneke van Asselen (Deltares) discusses soil movement and various methods for measuring soil movement. How much do peat soils actually move in a year? Why is it important to measure that and what measurement methods are there?
- Ramon Hanssen, professor of Geodesy (surveying) and Satellite Earth Observation at TU Delft, will show the latest developments and insights into the use of InSAR for measuring soil movement.
- Roeland de Zeeuw, Managing Director at Shore Monitoring & Research, will give a presentation about the use of What do we now know about measuring seabed movement with LiDAR?
- Of course there is also room to ask questions.
