Geographic information The basic functions of the system

The functions of the geographic information system are: data collection and editing are mainly used to obtain data and ensure the integrity of the data in the GIS database in terms of content and space. The purpose of GIS system data conversion is to ensure the integrity of the content and logical consistency of the data when it is warehoused.

Data acquisition and input: Obtain geospatial data, including maps, satellite images, geographical location information, etc., and input them into the GIS system.Data storage and management: Store and manage the collected geospatial data, including the organization, classification, indexing and updating of the data.

The basic functions of geographic information system include data input and editing, data storage and management, data query and analysis, and data visualization and output. First of all, data entry and editing are one of the basic functions of geographic information system.

Data. Geospatial data is the most basic component of a GIS application system. (4) Personnel. Personnel are an important component of the geographic information system. ( 5) Method. The method mainly refers to the comprehensive analysis method of spatial information.

Function of geographic information system: public geolocation basis. It has the ability to collect, manage, analyze and output a variety of geospatial information.The system is driven by analytical models, has strong spatial comprehensive analysis and dynamic prediction capabilities, and can generate high-level geographical information.

What is the Geographic Information System based on

1. Geographic Information System also Known as the land resource information system, it is a computer system that can connect geographical data and integrate and analyze it with other information.The geographic information system is based on geospatial data and adopts the geographical model analysis method to provide a variety of spatial geographic information in a timely manner.

2. Geographic information system is the intersection of multiple disciplines such as computer science, geography, surveying and cartography. It is based on a geospatial database and uses geographical model analysis methods to provide a variety of spatial and dynamic geographical information in real time to serve geographical research and geographical decision-making. Technical system.

3. The term GIS was first proposed, and the world's first GIS (Canadian Geographic Information System CGIS) was built for the management and planning of natural resources. Tomlinson's foresight in advocating the use of computers for spatial analysis and his leadership role in establishing CGIS have won him the honorable title of "Father of GIS".

4. The geographic information system is based on the geospatial database. With the support of computer software and hardware, it collects, manages, operates, analyzes, simulates and displays spatial-related data, and adopts the geographical model analysis method to provide a variety of spatial and dynamic geographical information in a timely manner, for geographical research The computer technology system established for the investigation and geographical decision-making services.

5. Geographic Information System (Geo-Information System, GIS) is sometimes also known as "Geological Information System" or "Resource and Environmental Information System". It is a specific and very important spatial information system.

6. GIS Geographic Information System isBased on the geospatial database, with the support of computer software and hardware, the theory of system engineering and information science is used to scientifically manage and comprehensively analyze geographical data with spatial connotations to provide a technical system of information required for management, decision-making, etc.
