Emergency Command System Of Gis-based Program Design

Emergency Command System is the command deployment operation systems,which run in the event of any emergency,including command and dispatch system, disposal of system, resources and support system, information management system, decision assistant system. GIS (Geographic Information System) is composed of computer hardware, software and different methods, which designed to support spatial data acquisition, management, processing, analysis, modeling and display, in order to solve complex planning and management issues. Experienced 30 years of development, GIS technology is becoming a complete technology system , establishing theoretical system, forming a multi-level and application of different scales pattern,becoming an important component of the information industry. As a comprehensive technology, GIS integrated with other technology, its development related other technologies, in particular the development of computer .In the area of software development, the maturing computer components technology is becoming one of the main streams of the development. Its rapid development triggered the computer-related information industry changes. GIS will be used to form emergency command system as components ,that will hot only give emergency command and the implementation of contingency great convenience, but also make emergency management more stylized, contingency process smoother and more rapidly, and also large extent reduce the loss of affected areas or people.This paper mainly expounded the concepts of emergency management, GIS-related theoretical knowledge as well as the application in the vast reality field, and a detailed description of the GIS-based emergency command system programming, including functional analysis of the detailed design procedures, code-writing class diagram .The process is writing and running under Windows Xp, SuperMap5 Objects as a basic software platform.Dot Net Framework2.0 as the programming environment, C# as the main programming language, SQL Server for database processing platform, Design to prepare an emergency command system which make the GIS as the core function. GIS detailed features include: the basic map functions, such as zoom out, zoom in, map pan and output images, spatial analysis, such as the neighbor analysis, path analysis, the latest facilities to find, Gps tracking and map display and special thematic map etc. This topic passed the related department to approve, the topic achievement has initially used in the national some department emergency command system.
