Study on the use of UAVs in forest monitoring
The use of UAV for forest monitoring is of great interest to various forestry-related research institutes on an international level. Due to the high costs and limited resolution of aerial imagery derived from satellite and manned-aircraft platforms as well as costly Laser Scanning acquisition methods, UAV photogrammetry provides a cost-effective alternative and enables institutions to acquire data at a high spatial and temporal data entirely in-house. Although cost-effective, the process of acquiring and processing data, in particular for the production of high quality photogrammetric points and multispectral imagery still requires further research especially when a low-cost system (< 30,000 EUR) is implemented.
Background and Objective
Potential outcomes of study:
- Tree Geometries (e.g. individual tree height)
- Automatic Tree stem positioning
- Tree top position and stem position comparison
- Gap coverage
- Cost-effective data acquisition workflow competitive to field methods (also large scale)
- Enhanced possibilities for long term monitoring (all data sets can be processed in the same way retroactively)
- Automized workflow for large scale acquisition
- Field Manual
Approach
At the Lysimeter station in Britz different options of UAV use is tested and the results are compared with terrestrial assessments.
