As an exploratory first step
towards documenting the spatial changes in the selected area, we visually
compare the spatial changes in the Indian Sundarbans and the Bangladesh Sundarbans
in 2000 and 2014. We use false colored red-green-blue (RGB) composites of
different band combinations of these two datasets to qualitatively analyze this
change. Shown in figures 3 and 4 are false colored RGB composites from 2000 and
from 2014 of the Indian and Bangladesh Sundarbans respectively. In these RGB
composites, land is shown as green and water as black. Varying shades of brown
are also seen in the water representing suspended sediment. The figures below
show changes in the areal extent of several small islands and of the shoreline,
widening and narrowing of water channels in different places, and differences
in the total suspended sediment in the water.
