Dataset Abstract:

These three images were collected during falling water conditions in the mid-1980s at three locations along the Amazon floodplain. We ran an unsupervised classification on the entire floodplain area visible in each Landsat TM image and excluded upland areas. Excluding the large river channels, the area of floodplain available for analysis was 4710 km2 in the western area, 3830 km2 in the central area, and 7300 km2 in the eastern area. The purpose of the classification was to provide a consistent description of floodplain land cover at several locations along the floodplain. For the unsupervised classification, we used all Landsat bands except Band 6 (thermal IR). We generated 40 clusters from the image data and then merged the clusters into a smaller number of classes, a method designed to avoid overlooking land-cover types with distinct spectral signatures but relatively low areal coverage. The merging was based on the spectral separability of the classes (transformed divergence). To identify the classes, we compared the spectral signature of each class, particularly the reflectances in the red, near-infrared, and mid-infrared bands, to known signatures of land-cover types in similar environments. We also used available ground information and information from other remote sensing studies conducted within the study areas (Ayres 1993; Wittmann and others 2002; Albernaz and Ford in MMP; Hess, in press; Costa and others 2002). The class names identify the materials present in the classification image; in some cases, these materials are not necessarily those present at all times of the year. Legend: Class 0: Non-floodplain areas and cloud-covered areas Class 1: Non-floodplain water Class 10: Floodplain water Classes 21-26: Floodplain forests, from dark (21) to bright (26) Classes 31,32,33: Areas of herbaceous and woodland vegetation, from dark (31) to bright (33) Classes 41-44: Dark areas of mixed materials: water, shade, vegetation, soil, and non-photosynthetic vegetation Classes 51-55: Bright areas of green vegetation mixed with soil and non-photosynthetic vegetation Image Dimensions: Near Tefe: columns : 3391 rows : 3238 West of Manaus: columns : 6593 rows : 2531 Near Santarem: columns : 6800 rows : 4139
