This article will explain in detail what are the components of the GIS system. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

The five components of GIS system are hardware, software, data, personnel and methods. Hardware refers to all the computer resources needed to operate GIS; software refers to all kinds of programs necessary for GIS to run; data is the most basic part of GIS application system; GIS needs people to organize, manage, maintain and update data; method refers to application model.

Geographic information system (Geographic Information System or Geo-Information system,GIS) is sometimes called "geoscience 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 (including atmosphere) with the support of computer hardware and software systems.

Location and geographic information are not only the core of LBS, but also the foundation of LBS. A simple latitude and longitude coordinate can be recognized and understood by users only when it is placed in specific geographic information and represented by a certain place, symbol and orientation. After users obtain the location information through related technologies, they also need to understand the geographical environment, query and analyze the environmental information, so as to provide information support and services for user activities.

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

The application system of GIS system consists of five main parts, namely, hardware, software, data, personnel and methods.

(1) hardware. The hardware of GIS system refers to all the computer resources needed to operate GIS. A typical GIS hardware system includes not only computers, but also external devices such as digitizers, scanners, plotters, tape drives and so on.

(2) Software. Software refers to all kinds of programs necessary for GIS to run, providing functions and tools for storing, analyzing and displaying geographic information. GIS software consists of computer system software, GIS tools or GIS practical software, as well as application programs.

(3) data. Data is the most basic part of a GIS application system. Data includes spatial data and attribute data.

(4) personnel. GIS needs people to organize, manage, maintain and update the system, expand the system and develop application programs, and use spatial analysis model to extract a variety of information.

(5) methods. The method here refers to the application model. It is the expression of the law summed up on the basis of a large number of studies on the specific objects and processes in the professional field. GIS application uses these models to analyze and synthesize a large number of spatial data to solve practical problems. Such as mineral resources evaluation model based on GIS, disaster evaluation model and so on.

This is the end of this article on "what are the components of the GIS system?". I hope the above content can be of some help to you, so that you can learn more knowledge. if you think the article is good, please share it for more people to see.
