Designs And Realization Of The Management Information System Of Civil Defense Based On GIS

With the power of air raid in the war strengthen under the modern high tech, the importance of the civil defense is more and more obvious as it is used for the important work to hide personnel and material in war and economy construct in peacetime. The high-speed development of our country's urbanization and the usage of the civil defense bring many problems for the management of the civil defense. How to adopt new technology to administer and use the civil defense effectively is a import and significant problem.According to the conception and theory of the OO(Object Oriented), the paper adopts the integration technology of MIS and GIS,designs and realizes the civil defense management information system. MapObjects 2.3 of ESRI as GIS development component is used in the system, and we build a series of data structure and classes for civil defense information. On the help of powerful data management of Oracle database, we realizes a series of functions, such as: the input, query, edit etc, on electronic map reaches expectant purpose, and manage the civil defense visually , intuitively, simply and effectively. Using GIS ability of geospatial data management and spatial analysis, we realizes some functions .For example,we making comprehensive estimation and analysis of the civil states in selectioned area; making the analysis of population circs in the covert of the single civil defense in some extent and making the analysis of the time of all people coming into the hiding entry, all these get good usage effect.
