| Abstract | Remote sensing is an auxiliary tool to access soil and environmental parameters, allowing synoptic and long time coverage. In this way, the combined use of Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) short wave infrared (SWIR) and thermal infrared (TIR) images were evaluated for the identification of sandy soil surfaces (topsoil) and associated land degradation areas. The images were acquired on September 7, 2006 over an agricultural area (soybean, maize and cotton) from central Brazil. Topsoil samples were collected for laboratory physical-chemical analyses. To discriminate non-photosynthetic vegetation (NPV) from bare soil pixels, the soil fraction image (>0.65) of the linear spectral unmixing model was used. As a complementary approach, SWIR (bands 5 and 6) and TIR (bands 10 and 14) normalizations with threshold values of 0.05 (dark soil) and 3 (bright soil), respectively, were applied. To estimate total sand fraction over bare soil pixels identified from the previous approach, a TIR band ratio (b10/b14) fitted with a polynomial regression (R2=0.63, Ñ=0.05) was used. Results showed that some areas with total sand fraction values larger than 90% were coincident with land degradation processes verified in field and caused by the abrupt removal of the Brazilian savanna (Cerrado) over quartz-bearing soils. | |||
