190 The Dutch Ministry of Transport, Public Works and Water Management uses their Enterprise Architecture framework to move from vertical (geo)applications towards a service oriented architecture with the emphasis on open standards. The main benefits are demonstrated in a real life use case demonstrating the flexibility of this setup in real life emergency situations. Emphasis will be put on the build-up of an Open Source Framework implementation using a variety of OSS (Mapserver, Chameleon, Geoserver and Deegree). The use of proprietary software (IONIC, ESRI) will be briefly discussed as well.
