Anonymous users2024-02-05A geographic information system is a system that processes geographic information.
Geographic information refers to information that is directly or indirectly related to the spatial location on the earth, also known as spatial information. In general, GIS can be defined as: "a computer system used to collect, store, manage, process, retrieve, analyze, and express geospatial data, and is a general technology for analyzing and processing massive amounts of geographic data".
GIS is composed of computer systems, geographic data and users, through the integration, storage, retrieval, operation and analysis of geographic data, generate and output a variety of geographic information, so as to provide new knowledge for land use, resource evaluation and management, environmental monitoring, transportation, economic construction, urban planning and administrative management of the first department, and provide services for engineering design and planning and management decision-making.
In China, geographic information system is also known as resource and environmental information system. The application system of GIS is mainly composed of five parts, including hardware, software, data, personnel and methods.
Introduction: Geographic Information System (GIS) is a data management system with a professional form of information system space. In the strict sense of the word, it is a computer system that centralizes, stores, operates, and displays georeferenced information.
For example, data can be identified based on its location in the database. Interns also often think that the entire GIS system includes the operator as well as the data fed into the system.
Geographic Information System (GIS) technology can be applied to scientific surveys, resource management, property management, development planning, mapping and route planning. For example, a geographic information system (GIS) can make it easier for emergency planners to calculate emergency response times in the event of a natural disaster, or to use a GIS system to identify wetlands that need to be protected from pollution.

At the same time, relying on these basic functions, GIS further deduces and enriches related functions by using spatial analysis technology, model analysis technology, network technology and database integration technology to meet the extensive needs of society and users.

Anonymous users2024-02-03There are five main functions of GIS:
1. Data collection and function: including graphic data collection and attribute data and analysis.
2. The basic skills of the geodatabase management system, including database definition, database establishment and maintenance, data rubber database operation, communication function, etc.
3. Cartographic function: According to the data structure of GIS and the type of plotter, users can obtain vector maps or raster maps. The GIS can not only output all-element maps for users, but also output various thematic maps in layers according to the needs of users, such as administrative division maps, soil use maps, road traffic maps, contour city maps, etc.
Some special geological analysis maps can also be obtained through spatial analysis, such as slope map, aspect map, profile and so on.
4. Spatial query and spatial analysis functions: including topological Qishen space query, buffer analysis, overlapping analysis, spatial set analysis, and geoscience analysis.
5. Terrain analysis function: including the establishment of digital elevation model and terrain analysis.
There are no requirements for computer performance, only your memory has 512M, and there is no problem with running GIS software. The key is to buy a computer and study hard.
ArcGIS Server is a tool used by Esri for WebGIS development, it is more complex to install, depending on your subject should not be used, ArcGIS Desktop is a desktop application, focusing on spatial analysis and data processing of data, and some of his functions can be called when AE is developed, such as the style manager that can directly call it with a simple ** and so on. But it is not recommended, but the basic environment of its AE development still needs to be installed. >>>More
Because of the management information system.
It is very important for modern enterprises and management, which is manifested as follows: >>>More
Management information systems, like all systems engineering, are established and continuously developed by human beings through organization, management, and collaboration. The groups of people linked by their participation in the establishment and development of management information systems form a social system under organizational management. The establishment and development of management information systems is both the goal and the output of this social system. >>>More
The program information of the Langge information release system is all collected and released by the background in a unified manner, and the program list is diversified, and multiple regional visualization operations can be realized in the region, providing a variety of materials (**file, **stream file, audio, **, text, real-time text, digital clock, **clock, weather forecast), and adjust the subtitle file position, size and superposition at will, we provide users with a variety of templates, which users can directly use or re-use the template to meet their own needs.
