Abstract
Usefulness of Landsat imagery in discerning major arid zone soils has been studied. Results are based on analysis of Band 7 coverage and Band 5 and 7 for a limited area followed by a comparison of these with the known soil distribution as seen in Bikaner, Jodhpur and part of Jalore, Pali and Nagaur districts. Results show that at Band 7 the dominant course loamy Typic Camborthids in association with dunes could be recognised. Vegetation was found non-interfering though surface soil moisture variation of the period immediately following monsoon months (Sept.–Dec.) appeared to do so. Hardpan soils were identifiable largely by their associated features than by soil characteristics proper.
