Geographic Information System (GIS) is sometimes called "Geo－Information system". It is a specific and very important spatial information system. It is a technical system that collects, stores, manages, calculates, analyzes, displays and describes the relevant geographical distribution data in the whole or part of the earth's surface space (including the atmosphere) with the support of computer hardware and software systems.

Geographic Information System (GIS) is a comprehensive subject, which combines geography and cartography, remote sensing and computer science. It has been widely used in different fields, and is a computer system for inputting, storing, querying, analyzing and displaying geographic data. With the development of GIS, Some people call GIS "Geographic Information Science", and in recent years, some people call GIS "Geographic Information service". GIS is a computer-based tool, which can analyze and process spatial information (in short, it is to map and analyze the phenomena and events that exist on the earth). GIS technology integrates the unique visualization effect and geographical analysis function of map with general database operations (such as query and statistical analysis).
