MEMO -TASK 89.1 Because of the enhanced radiometric calibration of Landsat 7, the planned approach was to select multi- date Landsat 7 images for the entire project area. However, because in many cases the Landsat 7 scenes for the required dates have considerable amounts of cloud coverage, Landsat 5 scenes will be selected instead for those dates and frames. Table 3 shows the sensor for each of the recommended image frames. Table 3: Recommended Landsat 5 & 7 Images for the SPDSS Study Area Additional to Path/Row 33/32.
