Research On The Organization And Service Of Emergency Geographic Information

In In recent years, unexpected events occur frequently in China, The Emergency Rescue have an urgent demand of the quick service emergency geographical information service.Emergency geographic information as an important part of geographic information, scattered in various departments, and there is no centralized management and sharing mechanism, when event occurs it is difficult to effectively analysis of the organization of emergency geographic information and the Share of data and services between departments, resulting in a waste of resources, low rate of utilizing emergency geographic information, a slow speed of data analysis, this will effect related emergency department decision analysis and comprehensive analysis, Greatly slowing the speed of disaster relief, reducing the efficiency of rescue. How to organize and manage the emergency geographic information quickly, and how to manage and share the emergency geographic information service, as the focus of this paper is discussed.The specific research contents and results are as follows:(1) Detailed classification of emergency geographic information and its services is discussed in this paper, analyze the specific sources of emergency geographic information and its service.(2) According to the category of emergency geographic information, the attribute demand of all kinds of emergency geographic information and emergency response departments for emergency geographic information service needs are analyzed.(3) This paper studies the management mechanism of emergency geographic information and service. According to different classification criteria, the emergency geographic information and services are organized in an orderly directory. Several collection methods of emergency geographic information data and the mechanism of data and service sharing are designed. proposed two emergency geographic information service publishing methods,realize the sharing of services.(4) Based on the research of emergency geographic information and service, a prototype system of emergency geographic information service is designed. It mainly includes three modules: data management, service management and integrated query. In the data management module, it mainly realizes the function of emergency geographic information data to add, data update and maintenance, data authorization and so on. In the service management module mainly realizes the service configuration, service registration, service authorization and so on. In the integrated navigation module, it mainly realizes the functions such as comprehensive browsing, data browsing, service browsing and so on.Through the research on the organization and service of emergency geographic information, the emergency geographic information is analyzed in detail, which is convenient for the management of emergency geographic information. The attribute demand of all kinds of emergency geographic information and the service demand of each emergency department are defined, which lays the foundation for establishing the emergency unified database.Formed a set of mature data and service management process, achieved the emergency geographic information and service sharing, Provides an important technical support for the construction of emergency geographic information service platform, to emergency departments quickly using the emergency information analysis and judgment. Improve the efficiency of the disposal of emergency incidents, Solve the merge of emergency geographic information is difficult, the use of low efficiency, difficult to solve the problem of service and other. The construction of the prototype system is a good display of the data and service management processes, as well as data and services overlay browsing, achieved the sharing of data and services. Due to the rapid change of emergency geographic information, the emergency geographic information real-time and rapid update also need further research.
