Description 331-342
Present study
intends to quantify change of natural vegetation cover (mainly of mangrove
forest) in Sundarbans
Island between the time
span of 2004-2010, when sustained efforts of a forestation and conservation has
been in vogue. Vegetation indices like Normalized Difference Vegetation Index (NDVI),
Global Environmental Monitoring Index (GEMI), Optimized Soil Adjusted
Vegetation Index (OSAVI) and Transformed Difference Vegetation Index (TDVI)
have been used to decipher the measure of vegetation cover in this island and
its changes during the period. Radiometric normalization technique is used to
nullify various imaging condition anomalies while comparing multi-temporal data
for change detection analysis. TDVI has been found to be more effective in
vegetation cover change detection in such deltaic environment. Present study shows
an overall net increase of vegetation cover in the island as a result of
sustained conservation and plantation efforts.
