Application of network geographic information system in environmental science

Abstract Environmental science is the study of various environmental elements and their interrelationships that human beings rely on for survival, including the understanding and transformation of the interaction between humans and the environment in nature. The science of relationships. This article discusses the specific application technology of D's distributed network geographic information system and AGENT technology's distributed geographic information system in environmental science.

Keywords geographical information system, environment GIS, distributed

Geographic information system is an information-related *** that integrates computer graphics and databases. It outputs geographical location and related attribute information to users with pictures and text. Users can make various auxiliary decisions with the help of its visual expression. The emergence of geographic information systems has changed the traditional way of processing information, allowing people to process information from the numerical field to the spatial field. Geographic information systems have always been closely related to information technology. With the rapid development of distributed computing technology and network technology, distributed computing technology, as a platform capable of carrying geospatial information, has become the most important direction of GIS development. A distributed geographic information system is an online geographic information system based on a distributed spatial database, with a group of distributed servers cooperating to provide geographic information services to clients. The network information system can effectively manage complex pollution source information in a large geographical area, and analyze in detail the changes in factors affecting the regional environment, as well as the geographical attributes and characteristics of major pollutants.

1. Characteristics of network geographic information systems

1. With the rapid popularity of the Internet, relying on the Internet to obtain information expands the application fields of geographic information systems. Use network software through ordinary browsers to enjoy geospatial information services, thereby reducing data distribution costs. For example, the emergence of digital maps allows people to abandon traditional printed maps and easily search for locations and routes on the Internet.

Superimpose the characteristics of different environmental influencing factors in the same area at different times to analyze the relationship between regional quality evolution and other factors. Predict regional environmental quality. In addition, the location of key pollution sources and their impact on the environment can be displayed on a plot map.

Second, achieve maximum sharing of resources. In order to achieve the ultimate sharing of information, an open network for user-oriented and resource-sharing is established. It has powerful spatial analysis and data processing functions and makes full use of the network's functional modules combined with selected environmental monitoring models to process multi-source environmental information to discover the dynamic laws of environmental evolution, establish scientific monitoring models, and realize environmental monitoring. Comprehensive dynamic monitoring.

Three, fast speed and high precision. Network distribution technology can be used to associate data with maps to establish topological relationships for spatial analysis, and to assist decision-making and management of various thematic maps. Not only does it save a lot of manpower, material resources, and financial resources, but the most important thing is that the results are obtained quickly and with high accuracy.

Four transparency, location transparency, that is, users do not need to know the location of files and databases, and the names of resources can flow freely in the system without changing their names. The outside world does not need to know the system to balance resources. And change the position of the object. The system can make additional copies of files at will without the user knowing, and in parallel without the user being aware. Hiding the similarities and differences between data representation and call mechanisms can hide errors and recovery events inside objects to achieve error correction.

2. Main performance methods of networked geographic information systems

One-D distributed networked geographic information system

1. With data management functions: 1. Attribute data are managed by a relational database, geospatial data are stored in the form of artifacts, and spatial operations are performed by spatial data management software packages. Establish connections between geospatial data files and relational databases through indicators or keywords; 2. Improve the relational database, manage attributes and spatial data in a unified manner, introduce object-oriented technology into the relational database, and establish object-relational data. Library or pure object database, objects and underlying representations are separated, spatial attributes and non-spatial attributes are positioned equally, realizing integrated management of attribute data and spatial data. With the advancement of technology, the client can adopt new protocols and use web technology to improve the new geographic information system. It can display multimedia data on the browser, and the information in WebGIS can query and analyze spatial data through interactive operations. Users can browse the spatial data on the site and perform various spatial data retrieval and spatial analysis.

2. Expression methods of distributed network systems: 1 Plug-in method. Using a distributed network system, some simple operations require the server to complete and return the results. When the network traffic is high, it is necessary to use plug-in technology and use software that can exchange information with the browser to transfer some service functions to the client, speeding up the response speed of user operations and reducing network traffic and server costs. load. It is also simple to operate, allowing ordinary users to easily obtain the information they need. Use a general browser to release geographic information, usually using free plug-ins, which greatly reduces the user's financial burden; 2 Cross-platform: no matter what system the client and server use, and what software is used on the server side , users can transparently access WebGIS data and realize the sharing of remote heterogeneous data; 3. Portability: A stateful spatial data transmission protocol can be implemented. After the same data transmission process, the establishment of data transmission between Contact to reduce the heavy network transmission burden. As an in-program expansion method, it effectively reduces the time consumed by the program. The client also does not have a data management mechanism, the execution speed is relatively fast, and the burden on the network and server is light.

A distributed geographic information system based on AGENT technology

It is a digital form that reflects various spatial data and descriptions of the current situation and changes in the earth's space on which human society depends. The attributes of these spatial data characteristics use a modeling method to simulate the behavior of earth space objects. With the support of computer software and hardware, they support input/output, storage, display and geospatial information query in a specific format. An effective tool to assist decision-making. In a word, geographic information systems provide people with advanced tools for managing geographic information and conducting spatial analysis. With the development of computer networks, computer communications and other technologies, the Agent system relaxes the restrictions on centralized and sequential control, provides decentralized control and parallel processing, and solves the problem of collaborative work between network distribution system application fields. Different Systems in the field cooperate with each other to complete related applications, analyze the interoperability issues of geographical information and geographical applications, mutually access information and interoperate in heterogeneous geographical information processing environments, realize effective management of resources, and perform high-quality geographical information Communication with services reduces frequent interactions between servers and customers, and can be used for local geographic calculations and secondary processing such as measurement and geographic modeling to provide personalized display of data. The specific performance of data can describe arbitrarily complex content, and has obvious advantages and characteristics, including realizing the sharing of spatial data and network distributed services, high-performance computing, and the security of data resources.
