India - Erosion and Accretion of Bangladesh and Indian Sundarbans

Drawing on mosaiced Survey of India “inch” topographical maps (1904-24), Corona space photos (1967), IRS-1D L3+Pan (2001), and IRS-R2 L4-mx (2015-16) satellite images, this dataset provides erosion and accretion of Bangladesh, as well as Indian Sundarban. Comparison between 1904–24 topographical maps and 2015–16 satellite images highlights the extent of erosion along nearly the entire surface of the western delta and accretion in the interior parts, mainly in the west.
