Satellite images and GIS enables government, state and emergency management to better prepare for hurricane impact on their region. Estimates of the particular land cover classes that may be inundated by each category hurricane can enable planners to better assess their region's risk and vulnerability. With this type of information, planners are better able to prioritize and target mitigation and preparedness activities for their area.

Prior to a storm, satellite images 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 the storm, satellite images can be used to determine the extent of landscape change and monitor the progress of recovery.
Damage and Recovery Assessments
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 for example, flooding, wind pressure, and storm surge.
High resolution satellite images can distinguish damage conditions of individual buildings, such as damage to roofs caused by wind pressure. Widespread flooding can be detected and monitored using less-detailed moderate-resolution imagery.
Rapid Acquisition/Rush Tasking
Rush tasking orders for satellite image data around the world are accepted in support of live events, natural disasters, global security, and various other applications in which FAST delivery of image data is critical. In most instances, we can provide image data within 24 hours after the initial data has been acquired and delivered via FTP and DVD media.
