The
Methodology adopted for the creation of Coastal Regulation Zone Information System
has been given in the Figure.1. Coastal Regulation Zone map on 1:25,000 scale
derived from satellite data were collected from Department of Environment and
Forests, Government of Tamil Nadu. The georeferenced coastal regulation zone maps
were digitized in ARC-INFO GIS. Digitised maps were edited, labeled and a layout
was prepared. The area statistics of different coastal regulation zone class in
the maps were generated and are represented in the Table below.
Bathymetry
maps of Tamil Nadu coastal area on 1:25,000 scale were prepared using 1975 naval
Hydrographic Chart, ARC-INFO GIS software and Surfer package.
The
secondary data has been collected from various departments and it is given to
GIS as an input. Using avenue script the Coastal Regulation Zone Information System
was created.
