Low-Cost Geological Reconnaissance for Artisanal and Small-Scale Mining: RGB–HSV Analysis of Rendered Google Earth Imagery in Arid Copper-Prospective Terrains of Chile and Balochistan
Advanced multispectral and hyperspectral remote sensing supports mineral and alteration mapping, but its imagery, specialist expertise and validation requirements may remain inaccessible to artisanal and small-scale mining operators during first-pass evaluation. This study evaluates how much defensible geological recon...
