Describe the appearance of forest and agricultural fields. The dark-red coloration of forest areas is visually similar to many agricultural fields, which are evident because of their rectangular shape. Furthermore, upland and bottomland forests display the same spectral signatures in this image. On this basis, the standard false-color composite is not effective in separating the upland forest from other types of vegetation cover in the scene. When the image displays, change to the NDVI256 palette.
Vegetation appears in green, non-vegetated surfaces are yellow, and water bodies show in brown.
For further processing, change the raw NDVI values into the byte-binary data type as follows. Explain your answer. Active, green vegetation biomass. Check TM, and enter files for July 87 bands 1-5 and 7. Describe the appearance of the study forest on the three images.
