Mapping of salt-affected land in Saurashtra coast using Landsat satellite data

Coastal salt-affected land is subject to variation in area as well as magnitude with time because of influence of coastal processes. In order to take corrective and protective measures, it is essential to have accurate information about such an area in the form of maps. Using conventional ground methods, mapping of such an inhospitable area is not only difficult and time-consuming but also expensive, laborious, and associated with vagaries of weather. Hence an attempt has been made to use remote sensing techniques for the purpose of preparing a map of one of the coastal areas of Gujarat state, providing information about the extent and magnitude of salt-affected land.
