Definition

Earth Resources – Power sources and renewable or nonrenewable materials occurring naturally on Earth. NASA Thesaurus, Washington, DC: National Aeronautics and Space Administration.

Remote Sensing – The collection of information about an object or phenomena by a recording device that is not in physical contact with it. The term is usually restricted to mean the methods for, and activity of, recording features and phenomena of the Earth's surface from a remote platform or vehicle. Typically the methods used record reflected or radiated electromagnetic energy, such as radiometry, photometry, spectrometry, and photographic and radar techniques. NASA Thesaurus, Washington, DC: National Aeronautics and Space Administration.

NASA Interest

Exhaustive Interest : Remote sensing as conducted from the air or from space, supporting ground truth studies.

Selective Interest : Theory, studies, results, developments, mapping, photographic presentations, and the like resulting from and related to earth resources; the Earth's geothermal reservoirs and its solar energy base.

Negative Interest : Geology and geodesy of a routine, earthbound study unless for ground truth or related purposes.
