|Title||TerraSAR-X Radar for Supporting Dynamic Monitoring of Flood-Affected Land Cover and Land Use in Wetlands in Semi-Arid Africa|
|Investigator||Seiler, Ralf - Technische Universität Dresden, Geoscience|
|Summary||The ecology of the inland delta of the river Niger (Mali) is determined by a mosaic of permanently, periodically and temporary flooded areas. Investigations on land cover and land use changes in this region highly depend on the availability of earth observation archive data. Monitoring of floodplains can benefit from spaceborne imaging radar data in a special way, as these EO data offer a number of advantages compared to data from optical sensors due to its specific acquisition parameters. TERRA SAR-X data provide high resolution multitemporal and multipolarized data. The acquired reflected radar signal is strongly related to phenomena of seasonally and annually shifting patterns of flooded /non-flooded areas. Main Objectives of the proposed project will be the analysis of the influence of system parameters
-different polarisation modi (dual and VV)
on the monitoring of flood extend and vegetation cover in the inland delta and its semi-arid environment. Special emphasis will be placed on the investigation of the applicability of multipolarised SAR data for a high quality discrimination of water surfaces and vegetation cover, especially sparse vegetation cover.
Research on the operationalization of data fusion of TERRA SAR-X data with existing ERS SAR and ENVISAT ASAR data as well as with data of optical sensors will increase classification accuracies of land use and land cover change assessment in the inland delta and its environment.
