What are the two components of a remote sensing system?

The correct answer identifies the essential elements of a remote sensing system, which consist of a sensor and a platform.

The sensor is the device that collects data about the environment, capturing information through various means such as imaging, thermal sensing, or radar. This component is crucial because it directly affects the quality and type of data gathered, influencing the ability to interpret and analyze the information received from the environment.

The platform is the vehicle or structure that carries the sensor and provides the means to position it in the desired location. Platforms can include satellites, aircraft, drones, or ground-based structures, each serving to facilitate the collection of data from different altitudes and perspectives.

Understanding these two components is fundamental to grasping how remote sensing systems operate and how they are utilized for applications in various fields such as environmental monitoring, agriculture, and urban planning. Other options like camera and drone, radar and satellite, or receiver and transmitter do not capture the broader definition that encompasses all types of remote sensing systems. They may represent specific instances or technologies but lack the general applicability of the sensor and platform concept.
