What is GIS?

GIS (Geography Information

System) is a computer technology system based on geospatial database, supported by computer software and hardware, which collects, inputs, manages, edits, inquires, analyzes, simulates and displays spatial related data, and adopts spatial model analysis method to provide various spatial and dynamic information in time for geographic research and decision-making.

it is a new science integrating computer science, surveying and mapping, geography, space science, mathematics, statistics and management. with its efficient data management ability, spatial analysis, multi-factor comprehensive analysis and dynamic monitoring ability, it has become an effective management decision-making tool and is widely used in land management, urban planning, environmental monitoring, disaster prevention and mitigation, engineering construction, real estate development, commerce and other fields.

At present, the application of GIS in tourism management and development is mainly manifested in the following aspects:

Tourism information query. The tourism industry mainly attracts tourists by providing detailed information services. GIS can provide tourists with all kinds of information about tourist areas. For example, in travel fairs, travel agencies, travel websites on the Internet, and multimedia tour guide systems, there are usually query systems with text, sound and pictures.

production of tourism thematic map. GIS has rich text and graphic editing functions, which can facilitate the relevant personnel to update and maintain the database. The way GIS stores data is usually hierarchical storage, so it can not only output data according to the needs of customers, but also output hierarchical or superimposed thematic maps of various topics.

tourism development decision-making. The spatial analysis function of GIS has been applied in the process of urban planning, and at the same time, it can also be used reasonably in the decision-making of tourism development.

under normal circumstances, firstly, the evaluation maps of topography, climate, traffic, geology, etc. and tourism resources are rationally superimposed, and then the priority development areas are selected. Then, the layout of tourism routes is reasonably arranged with the help of the network analysis function of GIS. Finally, the development potential and protected areas of scenic spots are determined as a whole with the help of the buffer analysis function of GIS.

Extended data:

The basic function of p>GIS is to convert tabular data (whether it comes from database, spreadsheet file or directly input in the program) into geographic graphic display, and then browse, operate and analyze the display results. Its display range can range from intercontinental map to very detailed block map. The display objects include population, sales, transportation routes and other contents.

GIS technology includes many basic technologies, such as database management, graphic image processing and geographic information processing. With the support of computer software and hardware, it uses the theories of system engineering and information science to scientifically manage and comprehensively analyze geographic data with spatial connotation, and provides solutions for planning, management, research and decision-making for various industries.

GIS logistics analysis software integrates vehicle route model, shortest path model, network logistics model, distribution set model and facility positioning model.

vehicle route model. It is used to solve the problems of how to reduce the logistics operation cost and ensure the service quality in the transportation of goods with one starting point and multiple destinations, including deciding how many cars to use and the driving route of each car.

network logistics model. It is used to solve the problem of finding the most effective distribution route, that is, the layout of logistics outlets.

allocation set model. According to the similarity of each element, all or part of the elements on the same layer can be divided into several groups to solve the problems of determining the service scope and sales market scope.

facility positioning model. Used to determine the location of one or more facilities. In the logistics system, warehouses and transportation lines * * * together form a logistics network, and warehouses are located at the nodes of the network, which determine how many warehouses are set up in a given area according to the actual needs of supply and demand and the principles of economic benefits, the location of each warehouse, the scale of each warehouse, and the logistics relationship between warehouses, etc., which can be easily solved by using this model.
