Hydrothermal mineral alterations in the Brady and Desert Peak geothermal fields
Results of the analysis of HyMap's spectra against know hydrothermally altered minerals in the Brady-Desert Peak Geothermal Areas. The analysis was performed using ENVI's Target Detection process against USGS library spectra for Chalcedony, Kaolinite, Gypsum, Hematite and Epsomite.
Each compressed file includes three raster images created after fusing the target detection results for all minerals:
_fusion_all - Contains the 8 layers resulting from target detection and fusion of the 5 minerals
_fusion_all_normal - Contains each layer as above, after Winsorization (99% percentile on the positive side only due to skewness of results), and normalization of each layer to achieve a range between [0-1]
_fusion_final - Contains a fused raster by sub-setting the normalized layers, with the results of MTMF, MTTCIMF, OSP and SAM. Both CEM and MF were discarded as being less accurate than MTMF, and TCIMF is less accurate than MTTCIMF, ACE results were discarded because they were notably different from the rest of the analyses.
The base_names are:
brady - Brady geothermal area only
desert - Desert Peak geothermal area only
hymap - Full image analysis comprising both the Brady and Desert Peak geothermal areas
