Remote Sensing And its Application in Agriculture

Sophia Brown

Hearing is the process of obtaining information about the earth's surface by measuring its reflected and emitted rays without direct contact with the object. In most distant sightings, this process involves the interaction between event radiation and the intended purpose (Figure 1) The most effective electromagnetic radiation for remote sensing involves visible light (VIS), near infra red (NIR) and infwared infrared (SWIR). )), in infrared (TIR) and microwave bands (Figure 2). Sensitive remote sensors record the event radiation reflected or emitted from objects while the active sensors emit their rays, meet the target to be investigated and return to the measuring instrument.
