Abstract
 Study of Saltpan Increment in Gulf of Cambay Using GIS Track: GIScience Author(s): Madhavi Pikle, Sunit Charatkar, R Biradar, Debashish Mitra In recent years, the country's coastal stretches have become a pressure point for indiscriminate and unsustainable development pressures. Satellite data and geographic information system provide an enviable tool of huge potential. Gujarat is one of the largest salt producing states in India. The coast of the Gulf of Cambay of Gujarat is enclosed by a number of estuaries, mud flats, salt marshes, islands, cliffs and mangrove forests. A study was carried out using IRS 1C/1D LISS III imageries to delineate changes in saltpan from 1995 to 2003. ERDAS IMAGINE 8.7 and ArcGIS 9 software were used. Also supervised classification was done to study various landuse and landcover changes. There was remarkable increment in saltpans, 53.91 Km2 from the year 1995 to 2000, 22.56 Km2 in 2000-2001 and 35.73 Km2 in 2001-2003. Coastal villages face problems due to devastation of natural habitats.
