Description: Das Projekt "Research into the Sensitivity of Fragmentation Metrics" wird vom Umweltbundesamt gefördert und von Universität Göttingen, Burckhardt-Institut, Abteilung Waldinventur und Fernerkundung durchgeführt. Tropical and subtropical forest are under special interest of conservation and climate change policies as they are hot spots for both biodiversity and carbon sequestration and at the same time they are facing big threats to be converted to other landuse systems. Remote sensing is one of the key technologies for forest cover and thus forest fragmentation assessments as it provides the possibility to monitor large areas with a reasonable effort. But as this technique commonly involves the use of optical sensors, limitations due to cloud cover are high in the wet tropics and subtropics. In 06/2007 the German aero centre DLR lunched a new satellite, TerraSAR-X, which is operating at the X-band. This makes it possible to acquire landsurface images independently of cloud cover. Objectives: Overall objective of this study is to research into the sensitivity of fragmentation metrics to the factors described above and to contribute to a more focused and more differentiated interpretation of fragmentation metrics. While this study takes forest and forest fragmentation as an example, it is a general methodological study and the results can immediately be applied to the fragmentation status of any other land use or land cover class. Beside this object, the potential of TerraSAR-X products for forest fragmentation assessments in the subtropics and tropics will be analysed. Therefore a fragmentation analysis of three study sites in Costa Rica will be carried out on the basis of optical and radar imagery.
