Overview of the development of GIS??? Urgent!!!!!

Why, buddy, ......There is an introduction in the encyclopedia...... whether it is good or not

Summary. Good afternoon, dear and glad for your question. Geographic Information System (GIS) is sometimes referred to as a "geoscience information system".

It is a specific and very important spatial information system. It is a technical system that collects, stores, manages, calculates, analyzes, displays and describes the relevant geographical distribution data in the entire or part of the earth's surface (including the atmosphere) space with the support of computer hardware and software systems. Presumably, you are looking to inquire about the subject major, see the analysis below.

Did you answer the second question?

e: The employment scope of GIS major is relatively wide: transportation, meteorology, geological departments and other large industries have employment channels.

S: such as traffic supervision departments, supported enterprises; Meteorological supervision departments, meteorological information service departments, early warning departments, etc. m is measured by the accuracy of the application of the subject; a. It can realize the ** of traffic congestion, weather and climate; r. Realize secondary disasters or dangers that can be avoided due to accurate early warning; t is for what happens in the next 24 hours up to 48 hours**.

A 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.

Geographic information system (GIS) is a technical system that stores, obtains, processes, analyzes, manages, represents and transmits geographic data (including topography, landforms, geomorphological changes, population distribution, socio-economy, geo-ridge environment, etc.) electronically.

GIS can integrate and analyze different types of geographic information to provide useful information and decision support about geographic location and spatial relationships. It is a comprehensive spatial information processing and application technology, which has been widely used in natural resource management, urban planning, transportation, power communication, environmental protection, disaster management, public safety and other fields.

Differential links between GIS and general information

1. Data type, GIS deals with geospatial data, that is, the location, shape, size and other characteristics related to the earth's surface. Whereas, general information systems usually deal with non-spatial data, such as text, numbers, sounds, images, etc.

2. GIS needs to represent geospatial data on the earth's surface, and commonly used data structures include points, lines, surfaces and volumes. General information systems use common data structures such as arrays, lists, trees, and graphs.

3. Data analysis, an important use of GIS is to analyze and model geospatial data to support decision-making, planning and management. General information systems focus more on areas such as data processing, processing and distribution.

4. Data**, GIS data** usually includes sensors, cameras, satellites, etc., to obtain information about geospatial data. The general information system covers a wider range of data, such as social, e-commerce, logistics information, etc.

5. Technical requirements: GIS needs to use a variety of technical means including scanning, interpretation, processing and analysis to process spatial data. Depending on the domain and business needs, these technologies may require different data structures, algorithms, and software tools. In contrast, general information systems require more diverse and flexible technologies.
