Research of major hazard management system of enterprise based on 3DGIS

The major industrial accidents have occurred from time to time, which has a serious threat to people's property and lives. This paper builds a major hazard management system based on 3DGIS, does some research about the system structure and the key technology, and analyzes and designs the main system's functions and database. The system displays and manages a variety of basic information and data of the major hazard by the three-dimensional visual method, simulates the consequences of the accidents, and assesses the disaster. The system provides a strong technical support for the safety control, accident prevention, and accident investigation of the major hazard.
