| Resumo | This paper presents an analysis of C band SAR acquired over the Tucurui reseervoir as part od the Saouth American Radar Experiment (SAREX-92) carrid out through a cooperation between ESA (European Sapace Agency), CCRS (Canadian Centre for Remote Sensing), INPE (Instituto Nacional de Pesquisas Espaciais)and Eletronorte (Centrais Eletricas do Norte, S.A). The reservoir was formed by damming the Tocantins river and flooded an area od approcimately 2430 Km2of forest land. Deforestation, forest burning and soil erosion is producing outstanding changes in the reservoir boundaries over the time. Attempts to use TM/Landasat to monitor aquatic weed infestation and changes in the water land boundary were limited to the dry season because of the heavy cloud cover from September thorough May. Radar data present an unique opportunity to obtain sensonal information on the reservoir boundaries and on the plant communities. During the experiment the Convair 580 SAR system acquired C band data at different modes (Nadir, Narrow and Wide modes)and polarizations (HH, VV< HV< and VH)Aerial color photographs at the 1:10 000 scale, TM/Landsat images and ERS-1 data were also acquird. In this paper the`empahasis is put on the differences between two parallel polarizations HH and VV obtained to simulate Radarsat and ERS-1 data respectively. To perform this asssesment a sub-image encompassing five different aquatic weed species (Eichhormia crassipes, Salvinea auriculata, Pistia stratiotes, Scirpus cubenses, Typha dominguensis)with various degrees of homogeneity and density and dead trees (paliteiros) was selected. Sar images were geometrically and radiometrically corrected and resgisteres to TM/Landasat data ERS-1 data. Preliminary results show an enhanced capability of rada data(SAR and ERS-1)for mapping the land-water boundary over water bodies affected by aquatic weed infestation. Macrophyte species, however, are better discriminated in the TM color composites. Three different species: Scirpus cubenes, Eichhornia crassipes and Salvinea auriculata were discriminated with SAR-C bands. They also proved to be useful to map the areas with different densities of dead trees (paliteiros). |
