As soon as weather permits following major natural disasters, the National Geodetic Survey begins aerial survey missions to assess damages to affected areas. Typical weather-related events include hurricanes, tornadoes, and floods. NGS responds to other events, such as oil spills, as well. Directly georeferenced-imagery data are collected, rapidly processed, and made available via open-source Geographic Information Systems (GIS). These data and images provide emergency and coastal managers with information needed to develop recovery strategies, facilitate search and rescue efforts, identify hazards to navigation and HAZMAT spills, locate errant vessels, and provide documentation necessary for damage assessment through the comparison of before-and-after imagery. Images are also available to view and download by the general public as a tool to assess impacts to their homes and community:
