Who gives Let me introduce the development of geographic information system in China

Third, the number of professional talents is increasing, and many universities have begun to provide geographic information system training.Some commercial consulting service companies began to work on geographic information systems, such as the American Institute of Environmental Systems (ESRI), which was founded in 1969.

The development of GIS in China is relatively late, and has gone through four stages, namely the stages of starting (1970-1980), preparation (1980-1985), development (1985-1995) and industrialization (after 1996). GIS has been applied in many departments and fields, and has attracted the high attention of *** departments.

In recent years, China's geographic information industry has maintained a high-speed development trend, the scale of the industry continues to expand, and some geographic information technology and products have reached or approached the current international advanced level.

year, Canadian surveyor R.F. TomliNson first proposed the term "geographic information system" and established the world's first geographic information system.

Geographic Information System

Geographic Information System is abbreviated as GIS. Sometimes also known as "geological information system", it is a specific and very important spatial information system.

Geographic information system is a system that processes geographic information. Geographic information refers to information directly or indirectly related to the spatial location on the earth, also commonly known as spatial information.

Geographic information system is a technical system that electronically stores, acquires, processes, analyzes, manages, represents and transmits geographical data (including topography, landforms, landform changes, population distribution, socio-economic, geographical environment, etc.).

GIS---Geographic Information System is a computer-based tool that can graph and analyze things and events that occur on the earth.

[The development of geographic information system]

1. Since the 1990s, the geographic information system has entered a stage of rapid development.

2. With the rapid development and popularization of computers, geographic information systems have gradually matured and been comprehensively promoted to the application stage worldwide. Third world countries have also begun to introduce, apply and develop their own geographic information systems.

3. GIS has developed into a powerful spatial data integrated processing technology system with multimedia network, virtual reality technology and data visualization.

4. Overview of GIS technology development: In the emerging information industry, GIS (Geographic Information System) as a set of computer science, geography, surveying and mapping, remote sensing, environmental science, urban science, space science and governance science and related disciplines, etc., have emerged rapidly in the past 30 years.

5. The era of big data: With the advent of the era of big data, GIS will further expand its scope of application and provide more accurate and comprehensive data support for applications in various fields through the analysis and mining of massive data.

What is the geographical technology of gis

1. Other information: gis refers to Geographic Information Science, that is, geographical information science major. Geographic information science is an undergraduate major in an ordinary university in China. The major code is 070504. It is awarded a bachelor's degree in science and a four-year study.

2. III) The development trend of geographic information system (GIS) In recent years, geographic information system technology has developed rapidly, and its main driving force comes from the increasing requirements for geographic information system in an increasingly wide range of application fields.

3. GIS technology (Geographic InformationSystems) is a product of the intersection of multiple disciplines. It is based on geographical space and adopts geographical model analysis methods to provide a variety of spatial and dynamic geographical information in real time. It is a computer technology system that serves geographical research and geographical decision-making.

4. Geographic Information System (GIS) is a kind ofComputer-based tools that can graph and analyze things and events that exist on Earth.
