A Geospatial Collaboration Information System for City Environment Assessment Based on Adaptive Workflow

摘要：

City environment assessment based on cyber-infrastructure includes the activities of information exchange,information system collaboration and service integration among multiple departments.The method of adaptive service workflow (ASW) for geospatial collaborative system is proposed.With considering of the service quality and optimization algorithm,the virtual workflow (VW) and optimized selection of service (OSS) model are given for the selection of the best service in distributed computing environment.An application example of city environment assessment for poison gas diffusion is developed with the information collaboration between weather bureau,city construct department and environmental department,and the experiment result of diffusion plume is visualized and overlapped with base map on Web client.
