Survey
of India topographic map, Remote Sensing satellite imageries, NHO-Chart, GSI
maps and ground-truthing data collected by Tamil Nadu PWD over the past four
decades have been used to extract the shoreline during the various periods. In
addition NIOT has marked the High Tide Line (HTL) during the years 2006 and
2013 which gives real time information on the behaviour of the shoreline. Data
is processed and analyzed using software ERDAS for image processing and Arc-GIS
for geospatial analysis respectively. Rate of shoreline changes are estimated
by overlay analysis in GIS environment. The influence of natural and
anthropogenic processes along the coast which is found to modify the shoreline
configuration has been analyzed.Shoreline has been mapped using Landsat
satellite data andTamil Nadu PWD ground truthing data for 1990, 2000 and 2006.
It is observed that the shoreline change is more than 30 meters between 1990
and 2006. Studies include linking the natural impacts due to geology of the
region and coastal geomorphology influenced by the River Cauvery on the
shoreline change.
