A method has been developed for capturing ground based hyperspectral images which allow the remote mapping of lithology and mineralogy. These data have been collected in combination with traditional ground based lidar data, acquired by Riegl's LMS-Z420i. The results allow the generation of hyperspectral virtual outcrops. Preliminary testing of the system has been undertaken on dolomitized limestone from a quarry in northern England. The results are encouraging and suggest that mineralogical variations can be mapped remotely. The resultant hyperspectral virtual outcrop has been used to quantify the spatially controlled degree of dolomitization with a degree of detail and precision not previously obtainable.
