The extensive field studies necessary to understand the development of desert sand seas are hampered by their large size and inaccessibility. Remote sensing data used in conjunction with detailed field studies and textural and mineralogical analyses of surface sediments at specific ground-control points can provide a wealth of information on dune types and activity, regional aeolian dynamics, sediment sources and thickness, and depositional history for sand seas. The information available from LANDSAT TM (VNIR), AIRSAR (microwave), and AVIRIS (high spectral resolution VNIR) is compared using Kelso Dunes as a test case.
