Methods of computer technology application in GIS

Dizzy, if you don't want to give points, it is recommended to check the relevant information yourself, and then filter the required part by yourself. If there is no relevant information, it can be solved by giving points above.

1. Resource management.

It is mainly used in the field of agriculture and forestry to solve the problems of distribution, classification, statistics, and mapping of various resources (such as land, forest, and grassland) in the field of agriculture and forestry. There are two main types of problems: "positioning" and "mode".

2. Resource allocation.

In the city, the distribution of various public facilities, disaster relief and mitigation materials, nationwide energy security, food and other institutions in various places are all resource allocation issues. The goal of GIS in this type of application is to ensure the most rational allocation of resources and maximize the benefits.

3. Urban planning and management.

Spatial planning is an important application area of GIS, and urban planning and management is the main content of it. For example, how to ensure the proportion and reasonable distribution of green space in the construction of large-scale urban infrastructure, and how to ensure that schools, public facilities, sports venues, service facilities, etc. can have the largest service area (urban resource allocation problem).

4. Land information system and cadastral management.

Land and cadastral management involves many contents such as changes in land use properties, changes in the contour of land plots, changes in cadastral tenure relations, etc., which can be completed efficiently and with high quality with the help of GIS technology.

5. Ecological and environmental management and simulation.

Regional ecological planning, environmental status assessment, environmental impact assessment, decision-making support for pollutant reduction and allocation, decision-making support for environment and regional sustainable development, management of environmental protection facilities, environmental planning, etc.

6. Emergency response.

In the event of major natural or man-made disasters such as floods, wars, and nuclear accidents, how to arrange the best evacuation routes and equip them with corresponding transportation and support facilities.

Answer]: The complete GIS logistics analysis software integrates the vehicle route model, the shortest path model, the network logistics model, the distribution set model and the facility positioning model to achieve the optimal design of the vehicle route bucket code, the shortest transportation path, the most complete logistics network, the most adequate equipment allocation, and the most reasonable facility positioning, so that the logistics analysis technology is more conducive to improving and selling high logistics efficiency and reducing costs.

GIS (Geographic Information Systems) is a product of the intersection of multiple disciplines, which is based on geographic space, using geographic model analysis methods, providing a variety of spatial and dynamic geographic information in real time, and is a computer technology system that serves geographic research and geographic decision-making. Its basic function is to convert the data (whether it comes from a database, an electronic file, or is entered directly into a program) into a geographic display, and then browse, manipulate, and analyze the results of the display. Displays can range from intercontinental maps to highly detailed neighborhood maps, with real-world objects such as population, sales, transportation routes, and more.
