Remote sensing in the UFZ is used as tool to fascilitate concrete thematic driven research in the fields of Soil and Landscapes, Vegetation, Water, Biodiversity and Urbanization.
Besides requiring different spatial and temporal scales, all fields exploit different sensors, use various approaches, and possess numerous investigation sites distributed globally. In order to get a brief overview of each of these aspects on the respective topic, follow the links given below.
Forests of the world are an important sink for carbon and of imense significance for the regulation of the climate. Most of all tropical rain forests play a descisive role, representing the majority of the above-ground biomass. Until now, these forests store more carbon than they emit (carbon sink), yet locally large differences may occur. Additionally, the influence of climate change and land-use on the carbon cycle in tropical forests is an important research field.
One objective is to estimate the biomass of these forests through the combination of forest models and remote sensing data, being able to supply information concerning the carbon cycle. One essential challenge plays the analysis and prediction of biomass across scales (upscaling) as, to date, the variation of biomass within a few hectare-large forest areas is less investigated. Specifically, for those areas unmanned aerial vehicle (UAV) are most suitable, as representative forest areas can be mapped cost-efficiently and flexible in spatio-temporal terms.
