Web Service Orchestration of OGC Web Services for Disaster Management

Flexibility and reusability are major goals when developing complex applications based on OGC Web Services (OWS). Within the project OK-GIS (www.ok-gis.de) we evaluate the suitability of the Web Service Orchestration (WSO) technology as possible solution for disaster management scenarios. We present an example of a part of an evacuation scenario after a bomb has been found. This scenario includes in particular the need for emergency route planning. We evaluate how the actions to be performed by the system supporting the rescue workers can be mapped onto a service chain of basic OWS. The service chain is represented as a BPEL document and can be executed in a web service orchestration engine, such as Oracle BPEL-engine. BPEL is a standard for service orchestration and means Business Process Execution Language.
