Full description

In the frame of a collaborative research project "Spaceborne mineral maps for critical metals exploration in the Gascoyne and Pilbara" (OD229547) between the CSIRO and the GSWA, hyperspectral satellite imagery was acquired from the Western Australian Gascoyne and Pilbara provinces and processed into a suite of mineral abundance, mineral composition and crystallinity mosaics, as well as green and dry vegetation layers. In order to evaluate the geological and mineralogical information provided by the satellite imagery, the mineral maps were compared with 1) GSWA’s 500K and 100K geological and regolith maps, 2) publicly available geophysical layers (i.e. radiometrics and magnetics) and 3) previously published mineral maps, processed from spaceborne multispectral (i.e. ASTER) and airborne hyperspectral (i.e. HyMap) VNIR-SWIR imagery. This work was complemented by a ground validation campaign in the Gascoyne, during which VNIR-SWIR and TIR field spectrometer data were acquired along transects and samples collected for further analysis.
This collection comprises the data generated in the frame of said project.
