Application of WebGIS for Government Emergency Management Based on Web Service

This paper describes the design and implementation of a Web Geographical Information System (Web-GIS) for government comprehensive emergency management, which is based on advanced technologies such as Service-Oriented Architecture (SOA), Web Service etc. and show how WebGIS could be used to support decision making and manage geospatial information in emergency risk management. This system is on the basis of unified geospatial framework, taking geospatial sharing and construction as the main clue, effectively integrate fundamental geographical information, social economy and population information with thematic resource information of all industries by the way of loose coupling. The emergency management system described in this paper as a practical example of WebGIS instantiation provides a tool to access spatial-related data for management as well as communication for emergency planners. This paper mainly introduces the design of system and service framework, analysis of business process and implementation of WebGIS system.
