High-resolution, laboratory acquired hyperspectral images of rock samples from the footwall of the Kangaroo Caves Cu-Zn deposit, Pilbara, Western Australia

Image sizes were 384 by approximately 1200 pixels, resulting in images of a width of 11 mm and a length of approximately 4 cm. The images are provided in reflectance. The raw images were converted to reflectance using dark current and white reference measurements acquired during the recording of the images.

The images are noise reduced by i) checking for bad pixels that produced anomalous pixel-values, ii) the identification and removal of bad bands near the lower (1000 nm) and higher (2500 nm) margins of the measured wavelength range, and iii) application of a spatial-spectral smoothing filter that averaged five spatial and two spectral neighboring pixel values. The images are provided in ENVI file format and can be opened/viewed in Hyperspectral Python.
