Design And Implementation Of Emergency Map Data Management And Control System

Throughout the Chinese and foreign history of ancient and modern, the key that decides the war is material support. Now the war has already combined with information technology, so it needs that the material support commanding staffs are able to react quickly to the situation and make right decisions. But the traditional way that marking and drawing current situation on the paper map is not meeting the requirements in current situations because of the low efficiency. Therefore, Designing a system that is used for displaying the current situation of emergency material support tasks and draw marks for the situation which is with fully function and high efficiency is needed.This article analyzes the functional needs from actual demand, and decides to use B/S architecture with 3 layers for the system. Application layer requires user to access and use the system from the browser that with Adobe Flash Player plugin. Business logic layer contains Flex application and Java application. Flex Application is used with Geoserver together to implement the base map that for displaying situations and drawing marks. And Spring frame and Hibernate frame are used to manage the entities, handle the logic business and provide accesses to Oracle Database. Flex codes and Java codes can send and receive data between each other with BlazeDS. In data layer, the system saves and queries the data in the system by using Oracle Database. In functional aspect, system contains 4 parts in general. Base data preparation part manages all of the data in the system. Base map display and display control part can display the entities in the system and provides tools for drawing and marking. Statistical analysis part can statistic data in the data packet and show the statistic result with table and diagrams. Display scheme part manages the way that entities show in base map.The system meets the requirements in general and has handled the problems in traditional way to display and mark the situation in emergency material support tasks, and provides a situation displaying and situation marking solution that is informational, high efficiency and is convenient for information sharing. This system also provides a data management and map displaying tools for the simulation and evaluation system for emergency material support tasks.
