摘要

Timely and reliable information on soils with respect to their nature, extent, spatial distribution, and potential and limitations/hazards, namely soil erosion by water and wind, soil salinity and/ or alkalinity, wetness, soil compaction, etc., is very crucial for optimal utilization of available natural resources on a sustained basis. Soil surveys, which hitherto have been conducted through conventional approach, provide such information. By providing synoptic coverage of the earth's surface at regular intervals remote sensing has augmented the efficiency of soil survey programmes.
