摘要
By making use of enhanced remote sensing data and on the basis of measured reflectance spectrum of different geotechnical species, the authors achieved type identification of loose soils which composed of different grain sizes in different depositional environments. The study found that, ASTER data with band combination of 721 could effectively identify the different geotechnical species with the best effect in highlighting different geotechnical species.
