Review of Remote Sensing-Based Methods to Assess Soil Salinity

Remote sensing is the process of collecting data about the earth’s surface and environment from a distance, usually by sensors mounted on ground equipment, aircraft, or satellite platforms. Depending on the spectral position of the bands, sensors collect energy that is reflected (visible [VIS] and

infrared), emitted (thermal infrared [TIR]), or backscattered (microwave) by a landscape surface and=or the atmosphere (Metternicht, 2007).
