Objectives

This project involves conducting a campaign to acquire, process, and analyze hyperspectral data on the ground in an open pit mine. At the same time, spectral signatures are also being collected on samples and drill cores from units of interest using a spectroradiometer in order to build a reference library for subsequent mapping and classification needs.

Methodology

1. Develop a systematic data collection method that takes into account the position of hyperspectral imaging stations and the viewing angles of the pit faces.
2. Compare the signatures obtained from hyperspectral images with those from the spectroradiometer.
3. Map the pit walls using hyperspectral data mosaics.
4. Perform mineralogical classifications.
5. Create a mosaic of hyperspectral data showing the different sides of the pits.
6. Evaluate the quality of the spectral signatures from the hyperspectral data and perform analyses to produce the various maps relevant to the two mining contexts.
