What is rs short for?

Rs is the abbreviation of remote sensing. Rs is the abbreviation of remote sensing, which refers to the method of obtaining the state information of the target by indirect means. Remote sensing technology, global positioning system (GPS) and remote sensing technology rs, as multi-scale and multi-dimensional spatial data sources of GIS, provide impetus for the application of GIS technology.

The role of remote sensing

Remote sensing is a new technology developed on the basis of aerial photography, which was developed in the early 1960s. Started for aerial remote sensing, since 1972, the United States launched the first land satellite, marking the beginning of the era of space remote sensing.

After decades of development, remote sensing technology has been widely used in resources and environment, hydrology, meteorology, geology and geography and other fields, and has become a practical and advanced space exploration technology.

Remote sensing uses remote sensors to detect the characteristics of ground objects from the air. According to the principle that different objects have different responses to the spectrum, it is of great significance to recognize various ground objects on the ground.

That is to say, remote sensors on flying objects such as airplanes, spaceships and satellites above the ground are used to collect ground data and obtain information from them, and ground objects can be identified through recording, transmission, analysis and interpretation.
