A large number of proprietary and open source applications exist to process remote sensing data. Abstract. (Electromagnetic radiation, which is reflected, scattered or emitted from the object. To facilitate the discussion of data processing in practice, several processing "levels" were first defined in 1986 by NASA as part of its Earth Observing System[22] and steadily adopted since then, both internally at NASA (e. g.,[23]) and elsewhere (e. g.,[24]); these definitions are: A Level 1 data record is the most fundamental (i. e., highest reversible level) data record that has significant scientific utility, and is the foundation upon which all subsequent data sets are produced. Terrestrial remote sensing depends upon the fact that surface features and certain other phenomena are recognizable by distinct 'signatures' which result from their differential response to electromagnetic energy. "Remote sensing is the science (and to some extent, art) of acquiring information about the Earth's surface without actually being in contact with it. IGARSS, Honolulu, USA, 2780–2782 8. applications.
