GPS (Global Positioning System) is a global (satellite) positioning system. It was successfully developed and put into operation by the United States and provided for military and civilian use. Its function is positioning and navigation.

GIS (Geographic Information System) is a geographical information system. It is a computer system used to collect, store, manage, process, retrieve, analyze and express geospatial data. It is a general technology for analyzing and processing massive geographic data.

RS (remote sensing) means remote sensing. It is a modern science and technology that uses sensors to collect the electromagnetic wave information of the target object without touching the object itself. After processing and analysis, the target object is identified and its geometry, physical properties, interrelationships and change patterns are revealed.
