Hyperspectral imaging and geophysics are tools for data collection by instrumentation not in direct contact with the object being studied. Remote sensing uses satellite and airborne imagery to look at variations in the earth's surface, while geophysics employs quantitative physical methods to study subsurface phenomena. The integration of geophysics and remote sensing with geologic mapping can be applied to a wide variety of investigations, such as mineral and energy resource assessments, environmental characterizations, groundwater studies, human health and ecosystems.
