Given the clear need for better understanding and quantification of vegetation dynamics and variability in the Amazon floodplain, the present study proposes to fully evaluate the synergistic use of Radarsat 2 and TerraSAR-X systems to study vegetation communities in the Amazon floodplain, through the following objectives:

  1. Evaluate the effectiveness of combined C and X band and multiple polarization information in providing an operational, accurate method for macrophyte cover mapping and monitoring in the Amazon floodplain environment;
  2. Evaluate the effectiveness of C and X band and multiple polarization information in discriminating woody vegetation cover and capturing the phenology of woody species in the Amazon floodplain environment;
  3. Evaluate the added capabilities of full polarimetric information for discriminating among tree, shrub and macrophyte species in the Amazon floodplain;
  4. Evaluate the relative effectiveness of ScanSAR data for large scale mapping of vegetation communities, when compared to standard resolution products;
  5. Evaluate the suitability of high-resolution C and X band images as a basis for visual interpretation and validation of classification results, in order to reduce ground truthing efforts for the inaccessible areas of the floodplain.
