The application of remote sensing technology in ecology began in the 1930s.

Remote sensing technology is a detection technology that emerged in the 1960s. Based on the theory of electromagnetic waves, it uses various sensing instruments to collect and process electromagnetic wave information radiated and reflected by distant targets. And finally imaging, a comprehensive technology to detect and identify various ground scenes. Through remote sensing technology, domestic high-resolution remote sensing images such as Gaofen-1, Gaofen-2, and Ziyuan-3 can be queried.

Basic concept:

Remote sensing technology is a technology that collects electromagnetic radiation information of ground objects from artificial satellites, aircraft or other aircraft to identify the earth's environment and resources. It is a comprehensive sensing technology that was gradually formed in the 1960s with the development of aerospace technology and electronic computer technology based on aerial photography and interpretation.

Any object has different electromagnetic wave reflection or radiation characteristics. Aerospace remote sensing uses remote sensors installed on aircraft to sense the electromagnetic radiation characteristics of ground objects and record the characteristics for identification and judgment. Putting remote sensors on high-altitude balloons, airplanes and other aircraft for remote sensing is called aerial remote sensing.

Mounting a remote sensor on a spacecraft for remote sensing is called aerospace remote sensing. The entire set of instruments and equipment that completes remote sensing tasks is called a remote sensing system. Aviation and aerospace remote sensing can sense from different heights, large ranges, quickly and in multiple spectral segments, and obtain a large amount of information. Space remote sensing can also periodically obtain real-time ground object information.

Therefore, aviation and aerospace remote sensing technology has been widely used in many aspects of the national economy and military. For example, it is used in meteorological observation, resource inspection, map surveying and military reconnaissance, etc.
