Geo information for disaster management : [Gi 4 DM ; First International Symposium on Geo information for Disaster Management Delft the Netherlands 21 23 March 2005 ; selected papers] Geo information technology offers an opportunity to support disaster management: industrial accidents road collisions complex emergencies earthquakes fires floods and similar catastrophes (for example the recent huge disaster with the Tsunami in South East Asia on 26 December 2004). Access to needed information facilitation of the interoperability of emergency services and provision of high quality care to the public are a number of the key requirements. Such requirements pose significant challenges for data management discovery translation integration visualization and communication based on the semantics of the heterogeneous (geo ) information sources with differences in many aspects: scale resolution dimension (2D or 3D) classification and attribute schemes temporal aspects (up to date ness history predictions of the future) spatial reference system used etc. The book provides a broad overview of the (geo information) technology software systems needed used and to be developed for disaster management. The book provokes a wide discussion on systems and requirements for use of geo information under time and stress constraints and unfamiliar situations environments and circumstances
