Abstract: The presented research work tested the suitability of remote sensing via unmanned aerial vehicles (UAV) and multispectral data as a low-cost solution for forestry applications.

High-resolution 6-band multispectral aerial image sequences obtained via UAV acquisition flights in three research areas in Austria were photogrammetrically processed to coherent datasets by the use of Structure-from-Motion technology. Resulting orthomosaics, digital surface and digital terrain models in resolutions from 2.5 – 5 cm were utilised in the subsequent object-based image analysis combined with a Random Forest classification modelling approach. The methodology facilitated tree species classification and vitality analysis with additional predictive mapping.

Our study delivered promising results for the application of UAV-based multispectral datasets in operational forestry. The developed methodology performed reliably in species classification and despite inherent research issue-related uncertainties showed great potential in the detection of differences in tree vitality.
