Spectral Wizard Allows Mine Operators to Detect Copper Deposits Customer Challenge GIS Specialists at the Sensores Remotos & GIS (SRGIS) in Santiago, Chile needed to find copper deposits in the Chuquicamata mine by using spectral signatures. Solution Achieved The Chuquicamata mine is the biggest porphyry copper deposit in the world. Investigators at SRGIS knew that the West Fault area had limited mineralization and sterile rock,yet to the east of the fault, they determined that there was copper mineralization. To further determine the viability of the mine, they developed a process to study the spectral responses in ASTER imagery of the area. During the investigation, the team used ENVI from begining to end of their image workflow. Since ENVI supports a wide variety of multispectral and h
