Geographic Information System (GIS)

Concept

Geographic Information System (GIS) is a specific spatial information system that, with the support of computer hardware and software systems, collects, stores, manages, calculates, analyzes, displays, and describes geographic distribution data related to the entire or part of the Earth's surface space.

Components and functions

GIS consists of computer hardware, software, geographic spatial data, application models, design and development personnel, and application personnel. Its main functions include: Data collection and input: By means of map digitization, aerial photography, satellite image processing, etc., geographic information is converted into digital information that can be processed by computers. Data storage and management: Effectively store and manage the collected geographic data. Data processing and analysis: Using geographic models to perform operations and analysis on data, extracting useful information. Data display and application: Display analysis results through maps, charts, and other forms to provide support for decision-making.

Application Fields

GIS has been widely used in the construction of the national economy, especially in the following fields: Natural resource survey: helps to understand and evaluate underground resources such as minerals and water sources. Environmental assessment: Provide detailed terrain, climate, and ecological information to help understand environmental changes and develop protection strategies. Disaster prediction: By analyzing historical data and real-time monitoring data, predict the occurrence of natural disasters such as floods and earthquakes. Urban planning: Used for the layout planning of urban transportation, buildings, and public facilities. Transportation: Provide route planning and analysis in transportation management.

Typical case

Nangong City Land Space Basic Information Platform Construction Project

! [Construction of Nangong City Land Space Basic Information Platform] (/survey/nangong. jpg) The 'One Map' of National Land Spatial Planning is based on natural resource survey and monitoring data, establishing a unified national land spatial basic information platform, and using the information platform as the base, combining various levels and types of land spatial planning to gradually form a 'One Map' of national land spatial planning, promoting data sharing among government departments and information exchange between government and society. The Central Committee of the Communist Party of China and the State Council have issued the "Several Opinions on Establishing a National Land Space Planning System and Supervising its Implementation", which clearly states that "in the future, the system of national land space planning should no longer be a compilation system, but should become a system centered around supervision and implementation". By utilizing technologies such as big data and intelligence, we will strengthen the supervision of planning implementation, establish a spatial planning "one map" implementation supervision information system, achieve top-down integration, establish a standard, system, and interface from top to bottom, and form a "one map" of national spatial planning. General Secretary Xi Jinping has repeatedly mentioned the need to carry out the relevant work of a unified map system in accordance with the requirements of a unified base map, unified standards, unified planning, and unified platform.
