Comparison of ASTER and Sentinel
In the ASTER VNIR-SWIR false colour composite im-age (Fig. 2A), exposed lithologies are highlighted by red, green and purple colours corresponding to the variable con-tent of silicate and clay minerals and iron-oxides, respec-tively. Rocks enriched in quartz2B). Get price
Description and validation of an automated methodology
However, the acquisition, processing, and analysis of such airborne data at regional and national scales can be time and cost prohibitive. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) sensor carried by the NASA Earth Observing System Terra satellite was designed for mineral mapping and the acquired data can be efficiently used to generate uniform mineral maps Get price
