Satellite Images for Natural Disaster Monitoring

Satellite images incorporated with geographic information systems (GIS) can give emergency officials a wealth of information for assessment, analysis and natural disaster monitoring such as droughts, landslides, floods, earthquakes, hurricanes, tornadoes, cyclones, volcanic eruptions and tsunamis.

Natural disasters have caused major loss of human lives and livelihoods, the destruction of economic and social infrastructure, as well as environmental damages from small to large regions around the globe.

Prior to a disaster, high resolution satellite image data helps pinpoint where previous disaster events have occurred, where they are likely to occur in the future and the costs associated with historical events. After a natural disaster, satellite images can be used to determine the extent of landscape change and monitor the progress of recovery. Satellite imagery allows a larger land mass to be studied in a shorter amount of time than is possible with traditional ground cover study methods.

Satellite images gives state and government agencies the ability to view the damage from multiple vantage points. The spatial resolution of an image determines the ability to view individual features such as buildings and bridges. It also affects the ability to monitor and assess damage conditions, and depends on the nature of the disaster itself.
