The U.S. Geological Survey (USGS), as part of the National Assessment of Coastal Change Hazards (NACCH) project conducts baseline and storm-response photography missions to document and understand the changes in the vulnerability of the Nation's coasts to extreme storms and longer-term processes related to sediment supply and sea-level rise. On November 14, 2006, the USGS's NACCH project conducted an oblique aerial photographic survey from the Harney River, Everglades National Park, Florida to Anclote Key, Florida, aboard a U.S. Coast Guard Helicopter at an altitude of 500 feet (152 meters) and approximately 1,200 feet (366 meters) offshore to collect baseline data.
