In the emerging information industry, GIS (Geographic Information System), as a new frontier discipline integrating computer science, geography, surveying and mapping remote sensing, environmental science, urban science, space science, governance science and related disciplines, has risen rapidly in the past 30 years.
GIS combines computer technology with spatial geographic distribution data, and provides useful information for the planning, governance and decision-making of earth science, environmental science and engineering design, and even corporate governance through system establishment, spatial operation and model analysis.
At present, GIS has been widely used at home and abroad, not only in the fields of surveying and mapping, cartography, resources and environment, but also as an important tool for urban planning, public facilities management and engineering construction. In addition, GIS has also entered various fields such as military strategic analysis and decision-making, business planning, culture, education and health, and even people's daily activities.
At present, GIS is considered as a pillar industry in the 2 1 century and an important part of the information industry. During the Ninth Five-Year Plan period, the Ministry of Science and Technology listed the geographic information system as the "top priority" project, focusing on supporting the development of the geographic information system industry in China. ?
Extended data
The development of geographic information system in China is about 15 years later than that in advanced countries in Europe and America, but the development speed is not very slow. 1In September, 1994, the State Bureau of Surveying and Mapping of China signed the ARC China cooperation plan with the ARC/INFO headquarters of the United States.
Only the applications of GIS in cities include urban tap water, urban gas, urban planning, urban underground pipelines, urban environment, urban roads, urban land, etc. Other applications such as environmental monitoring, soil erosion, mineral resources and investment evaluation are more common. All these indicate the growth and development of GIS in China. ?
