Hyperspectral sensors are relatively underexploited tools for geothermal resource exploration. However, both short wave infrared (SWIR) and long wave infrared (LWIR) hyperspectral sensors have demonstrated the potential to play a much more significant role as geologists continue to seek innovative exploration technology to reduce the exploration risk. Exploration managers are becoming familiar with hyperspectral data and derived imagery. The data derivatives are used in the early stages of a phased exploration approach to establish a better understanding of the regional structural setting, and allow the project geologist to optimize field-based exploration methods such as seismic and drilling. However, there is more opportunity for researchers and geologists to expand on the ways that hyperspectral data can provide clues about geothermal systems, especially hidden or "blind" systems. Characterization of surface temperature measurements, development of new target mineral spectra, and recognizing regional trends are some examples of areas where more knowledge and experience will result in more robust data interpretation.
