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!

Oyu Tolgoi from Space

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.

Sentinel-2 resolutions

What level of spatial detail by Copernicus Sentinel-2 data is suitable for your application? Here we see three examples from Cape Town for the three different versions of resolutions of Copernicus Sentinel-2 (10m, 20m, 60m).

South Africa surface mapping

Are you interested in identifying the most prominent surface covers in a country? Resens+ Space can provide you with this information. Here you can see the spectraly most prominent surface cover types of South Africa based on Copernicus Sentinel-2 data.
