A remote sensing system has two components. Which option correctly lists both components?

• A. Receiver and Transmitter
• B. Camera and Lens
• C. Sensor
• D. Sensor and Platform

Answer: (D)

In remote sensing, a system has two essential parts: the sensor that collects data and the platform that carries it. The platform provides the moving vehicle—such as an aircraft, satellite, or drone—from which observations are made. The sensor is the instrument that detects electromagnetic energy from the ground and converts it into signals or images that can be processed. Together, they enable data collection from above the Earth. Why this pairing is the best fit: you need both a capable carrier and a sensing instrument to capture information remotely. A camera and lens describe a specific imaging device, but not the carrying vehicle. A single sensor describes only one piece of the system. A receiver and transmitter refer to a communications link rather than the sensing setup. The combination of sensor and platform captures data from a distance and situates the instrument within a moving or stationary platform, which is the core idea of a remote sensing system.
