Analysis of Alter Messages formats for Environmental Disaster Management

Crisis and emergency management require fast response times and the most efficient use of resources. It is required to have an effective response to hazards, for example, calls for early alert, reliable and accurate position information about the location of event. Police and emergency services need reliable and accurate knowledge of the location of deployed forces in order to coordinate them efficiently. This issue is particularly critical when the 'traditional' infrastructures are not available because of the emergency conditions (i.e. floods, maritime emergencies, oil spills, earthquakes and humanitarian aid operations). In this paper a contribution to environmental disaster prevention and management is given by the analysis of parameters relative to the identification and georeferencing of different kind of natural and anthropic emergenciesthrough the study of the format of the Common Alerting Protocol (CAP) version 1.2, implemented by Oasis, that allows a consistent warning message to be disseminated simultaneously over many different warning message to be disseminated simultaneously over many of transmission of alter messages are also examined including the possibility to use EGNOS (European Geostationary Navigation Overlay System) SIS (Signal In Space). The final objective is the extraction and real time visualization of the information on a mobile device (PDA, mobile phone).
