Satellite Images and GIS in Natural Disaster Mitigation
Satellite imagery and GIS maps can give emergency and disaster response officials a wealth of information for assessment, analysis and monitoring of natural disasters such as hurricanes, tornadoes and cyclone damage from small to large regions around the globe.
Estimates of the particular land cover classes that may be inundated by a natural disaster can enable operators and planners to better assess their region's risk and vulnerability. This information will allow for prioritizing target mitigation and preparedness activities for their area.
The use of multispectral satellite imagery is therefore critical for the separation of constituent materials within an image and for the interpretation of images of damage for pre or post-disaster assessment. View Before and After example satellite images here.
