The desertic terrain of Rajaslhan, India, has been evaluated to work out the logistics relevant to planning a hydrocarbon exploration programme. The digitally enhanced, high-resolution Landsat-5 Thematic Mapper (TM) and SPOT data has helped in identifying various aeolian landforms. Sand dunes are most conspicuous. On the basis of sand-dune abundance, their amplitude, wavelength and direction, three land systems have been identified in the area. The gcomor-phic information extracted from the aforesaid satellite data has been used to assess each land sysem for its feasibility for seismic profiling, drill-site construction and groundwater location.
