What is rs geographical technology?

rsRemote sensing is an emerging technology developed in the early 1960s based on aerial photography technology.

Beginning as aerial remote sensing, since the United States launched the first Land Satellite in 1972, this marked the beginning of the aerospace remote sensing era. After decades of rapid development, remote sensing technology has been widely used in fields such as resources and environment, hydrology, meteorology, geology and geography, and has become a practical and advanced space detection technology.

Remote sensing refers to non-contact, long-distance detection technology. Generally refers to the use of sensors/remote sensors to detect the radiation and reflection characteristics of electromagnetic waves of objects. Remote sensing uses instruments that are sensitive to electromagnetic waves, such as remote sensors, to detect target objects far away from the target and without contacting the target object.
