Soil survey constitutes a valuable resource inventory linked with the survival of
life on the earth. The technological advancements in the field of remote sensing and Geographical Information System have been a boon for such surveys. Present paper describes the
role of remote sensing and Geographical Information System (GIS) technologies for mapping
and characterizing soils at various scales. The spectral behaviour of soil and its components,which is fundamental to deriving information from remote sensing data, is also discussed with the scope of present day remote sensing data for varying levels
illustrations. Furthermore formation generation is also reviewed
Resumen: El levantamiento de suelos constituye un valioso inventario de recursos ligado a
la supervivencia de la vida en la tierra. Los avances tecnológicos en el campo de la percepción
remota y los Sistemas de Información Geográfica han representado un gran adelanto para
