What does gis mean

1. GIS System, that is, Geographic Information System (GIS, Geographic Information System) is a computer-based tool that can map and analyze things and events that occur on the earth.

2. Geographic information system (GIS) is sometimes also called "geological information system". It is a specific and very important spatial information system.

3. GIS is a geographic information system. GIS is the abbreviation of Geographic Information System. GIS is a computer space or space-time information system that expresses, acquires, processes, manages, analyzes and applies the characteristic elements of geospatial entities and phenomena.

4. The full name of gis is Geographic Information Science, that is, the major of geographic information science. 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.

5. gis is the abbreviation of geographical information system, which means geographic information system.

6. gis means geographic information system. GIS is a discipline developed with the development of geographical science, computer technology, remote sensing technology and information science.

What is gis?

gis is a specific and very important spatial information system. Its full name is Geographic Information System, abbreviated as GIS, and its Chinese name is Geographic Information System, sometimes also called "Geographic Information System".

GIS is a geographic information system. GIS is the abbreviation of Geographic Information System.GIS is a computer space or space-time information system that expresses, acquires, processes, manages, analyzes and applies the characteristic elements of geospatial entities and phenomena.

GIS: Geographic information system, sometimes also known as "geological information system" or "resource and environmental information system". It is a specific and very important spatial information system.

GIS definition refers to a computer system that collects, stores, processes, analyzes, retrieves and displays spatial data. It is a discipline and a technology that processes spatial data. At present, GIS has a wide range of applications in all walks of life, such as the land industry, planning industry, etc.

Development status and trend of geographic information system

Big data era: With the advent of the big data era, 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.

In a word, the GIS industry has great development potential and future. In the short and long term, it will be a career field full of opportunities and bright prospects, which can bring relatively high treatment and a more comfortable professional environment to the majority of practitioners.

The main development trends of information systems include the following points: integrating and sharing information between multiple units, industries and regions, and establishing a global information system to improve the efficiency, effectiveness and economic benefits of the information system.

The composition of GIS

What does the GIS system consist of? From the perspective of the computer, the geographic information system (GIS system) is composed of four elements: computer hardware, software, data and users.

Here, the software and hardware of the computer system are its core parts. Spatial data reflects the geographical content of GIS, while managers and users determine the working method and information representation of the system (Figure 10-2).

personnel are the most important components in GIS. Developers must define various tasks executed in GIS and develop processing programs. Skilled operators can usually overcome the shortcomings of GIS software functions, but the opposite is not true.
