What are the application fields of GIS?

It is mainly used in agriculture and forestry to solve the problems of distribution, classification, statistics and mapping of various resources (such as land, forest and grassland) in agriculture and forestry. Mainly answer "positioning" and "mode" two questions.

2. Resource allocation?

All kinds of public facilities in cities, distribution of materials for disaster relief and reduction, nationwide energy security, food supply, and institutional allocation in various places are all problems of resource allocation. The goal of GIS in this kind of application is to ensure the most reasonable distribution of resources and maximize benefits.

3. Urban planning and management?

Spatial planning is an important application field of g is, and urban planning and management are its main contents. For example, in large-scale urban infrastructure construction, how to ensure the proportion and reasonable distribution of green space, how to ensure schools, public facilities, stadiums, service facilities and so on. Can have the biggest service (urban resource allocation) and so on.

4. Land information system and cadastral management?

Land cadastral management involves the change of land use nature, plot outline, cadastral ownership and many other contents. With the help of GIS technology, these tasks can be completed efficiently and with high quality.

5. Ecological and environmental management and simulation

Regional ecological planning, environmental status assessment, environmental impact assessment, pollutant reduction and distribution decision support, environmental and regional sustainable development decision support, environmental protection facilities management, environmental planning, etc.

6. Emergency response

Solve the problem of how to arrange the best evacuation route and equip the corresponding transportation and security facilities in the event of major natural or man-made disasters such as floods, wars and nuclear accidents.

Characteristics of GIS

Geolocation Basis 1 and Gong * * *;

2. Ability to collect, manage, analyze and output all kinds of geospatial information;

3. The system is driven by analysis model, which has strong spatial comprehensive analysis and dynamic prediction ability, and can generate high-level geographic information;

4. It is a man-machine interactive spatial decision support system for geographical research and decision-making.

Development space:

Many disciplines benefit from geographic information system technology. The active geographic information system market leads to the low cost of GIS components and the continuous improvement of software and hardware. These developments in turn lead to the wider application of this technology in science, government, enterprises and industry.

Applications include real estate, public health, crime map, national defense, sustainable development, natural resources, landscape architecture, archaeology, community planning, transportation and logistics. Geographic information system is also divided into Location Services (LBS).
