Verbundprojekt ForestHype; Teilprojekt: Erhebung von Waldschäden und Abschätzung der oberirdischen Biomasse aus Hyperspektraldaten.
Description of the project:
The project ForestHype which is conducted in the framework of the EnMAP-mission aims on the development of methods in the field of forestry related hyperspectral remote sensing. Main goal of FELIS are the derivation of biomass and the detection of stressed/damaged trees.
Satellites providing imagery with high spectral resolution are still rare at present. The two currently operating satellites in space (CHRIS/PROBA, Hyperion) both show weaknesses (spectral range and Signal-to-Noise-Ratio respectively). The German satellite mission EnMAP wants to change this situation. As the name of the satellite “EnMAP – Environmental Mapper” already tells the overall objective of the system is to observe the environment in all of its facets. Within the group of EnMAP-projects ForestHype will cover the forestry sector. The main goals defined by FELIS are on the one hand the derivation of biomass on stand level and on the other hand the development of indices focusing on the detection of stressed or damaged trees. For both objectives a robust classification method to separate tree species is required in order to improve already existing methods. Preliminary examinations in the predecessor project HyMap showed that a combination of methods from multivariate statistics (Principal Component Analysis, Minimum Noise Fraction) and a classification algorithm (Support Vector Machine, kNN, Maximum Likelihood…) provided promising results in terms of tree species separation. Besides the already described target variables biomass and damaged trees another important methodical focus will lay on the adaption of methods developed based on HyMap-data (high spatial resolution with ca. 4m Ground Sampling Distance (GSD)) to simulated EnMAP-data with 30m GSD.
