This handbook reviews the techniques, methodologies and best practices for using geospatial information in support of decision making for disaster risk management. The focus is on specific hazards, including flood, cyclone, earthquake, landslide, volcanic activity and forest fire. While space-based information can significantly enhance disaster emergency response and preparedness, maps may often look similar. The nature of different types of hazards requires a range of theme-specific information or data sets that may not be immediately apparent, or available in one single map or information product. This handbook thus addresses the needs of disaster managers and geospatial information providers who must remain aware of the decision-making considerations for different hazard contexts.
