Oyu Tolgoi PCA analysis

Today is a comparison to that with the widely used statistical principal component analysis PCA which indicates areas of spectral homogeneity – but nothing more. The PCA aids your exploration by detecting surface patterns, but ReSens+ points straight to the expected mineralisation!

Here’s the best and second best fit of the spectral library features of the Sentinel-2 data for the Oyu Tolgoi mine in Mongolia. They show the surface pattern of strong iron mineralization but also the expected increase of carbonate and chlorite in the open pit.

rad.Data Spectral Analytics presents: How site-specific material libraries can improve the overall mapping of hyperspectral imagery using ReSens+ mapping algorithm “EnGeoMap”

Hyperspectral imagery in mining operations opens the possibility of mineral & ore-classification, and (semi-)quantitative maps in a diverse and changing mining environment. Tripod or drone-based (UAV) measurements can generate updated and pixel-precise ore-classification maps of a mine within 1-2 hours based on site-specific and georeferenced hyperspectral library data.
