Taking measurements of reflected and emitted radiation from soil or plant materials.
It involves the visible (VIS) (0.4-0.7 μm), near-infrared (NIR)(0.7-1.1μm), shortwave-infrared (SWIR)(1.1-2.5μm), and thermal-infrared (TIR)(7-14μm) spectral bands.
Platforms include satellites, aircraft, and UAVs.
Measurements made with tractors and hand-held sensors are known as proximal sensing.
Spaceborne and UAV/airborne sensors.
