Research Topics
- Development of methods to analyse the dynamics of ecosystems from time-series (optical and SAR), especially for degradation processes or abrupt damages (e.g. caused by fire or storms)
- Relation of temporal and spectral signals to plant traits and biophysical variables (xantophyll, nitrogen, chlorophyll and fluorescence)
- Derivation of operationalizable and comprehensive environmental indicators that are needed for the effective implementation of management measures (e.g. within the framework of the European NATURA 2000 requirements) or for a better understanding of ecosystems
- Interaction of vegetation structure, which can be measured with LiDAR or SAR, with spectral information for the evaluation of forest properties
- Combining spatially very high resolution data (drones) with satellite data to understand ecohydrological processes and especially to derive hydrological variables such as soil moisture content or interception

| Abstract | Insect defoliation causes forest disturbances with complex spatial dynamics. In order to monitor affected areas, decision makers seek but often lack information with high spatial and temporal precision. Within the context of a riparian Tugai forest disturbed by the insect Apocheima cinerarius, this study examines whether the analysis of a RapidEye time series would benefit from the availability of synthetically generated images at the spatial resolution of RapidEye and the additional temporal resolution of Landsat 8. We applied the Enhanced Spatial and Temporal Adaptive Reflectance Fusion Model (ESTARFM) to downscale Landsat 8 Normalized Difference Vegetation Index (NDVI) scenes to concurrent RapidEye NDVI scenes.We a) performed a pixel-based regression analyses in order to evaluate the quality of the synthetically created NDVI products and b) examined if forest disturbance maps producedwith synthetic images improve the accuracy of disturbance detection. The results show that the ESTARFM predictions have a sufficiently good accuracy, with a correlation coefficient between 0.878 b r b 0.919 (p b 0.001) and an average root mean square error 0.015 b RMSE b 0.024. The overall accuracy of forest disturbance detection with added synthetic images increased from 42.8% to 61.1 & 65.7% compared to the original data set. Forest recovery detection accuracy improved from 59.5% to 80.9%. The main source of error in the disturbance analysis occurs during the temporal interweaving between foliation and defoliation in spring. |
