Mineral Mapping Using Spectroscopy: From Field Measurements to Airborne and Satellite-Based Imaging Spectrometry

Mineral physics dictate the appearance of rocks and soils across the electromagnetic spectrum. In the Visible/Near-Infrared (VNIR) and Short Wave Infrared (SWIR), many materials absorb radiation at specific wavelengths, allowing their identification by the position and character of absorption features. Imaging spectrometer datasets have been acquired around the world using airborne platforms and recent satellite systems provide spectral measurements for selected areas. The case history presented shows an example of the progression of imaging spectrometer data to its current state-of-the-art and demonstrates the link between laboratory, field, and imaging spectrometer data.
