For more than three decades, geologists have been using passive remotely sensed data, both multispectral and hyperspectral, for geological applications such as mapping, structural interpretation, pollution and mine tailings, prospecting for Earth mineral resources as well as planetary geology. Since its beginning, spaceborne multispectral imaging has provided continuous full global coverage. The significant advantages of multispectral imaging are the continuous wide area coverage in connection with long-term availability as well as the reduced level of complexity and computational requirements for data processing. The launching of new satellite missions, such as…
