Development of an early warning information infrastructure using spatial web services technology

Abstract

Current high-performance monitoring and early warning systems are comparatively expensive and inflexible. The project described here aims for a systematic development of a prototypical alarm and early warning system for landslides utilising low-cost ad hoc wireless sensor networks and flexible spatial web service technology. Using web-based services as tools to exchange environmental data is an important step towards addressing today's larger scale environmental problems. The project's information system functions for notification, data access and analysis are implemented utilising Open Geospatial Consortium web service specifications. Approaches to implementing the orchestration of operation workflows and production of near real-time information products are illustrated. © 2010 Taylor & Francis.
