Both image oriented as well as computer-aided numerical approaches have been used in this study. Delineation of areas affected by salinityalkalinity, erosion, water logging etc. have been successfully done for some areas in the country. The problems and prospects in utilisation of Landsat data for mapping of soils and their limitations have also been discussed.
