This reference manual provides in-depth knowledge on the techniques, methodologies and best practices for using geospatial information in support of decision making for disaster risk management for specific hazards. Space-based information can significantly enhance disaster emergency response and preparedness and producing and using such information is critical for evidence-based decisionmaking. While maps may often look similar, the nature of different types of hazards requires different, thematic-specific information products, which may not be immediately apparent. Disaster management decisions require specific information and data sets that may not be available in one single map or information product. The handbook has been designed for the needs of disaster managers and geospatial information providers who must remain informed of the information needs, as well as the decision-making considerations for different hazard contexts.
