Oblique Aerial Photographs from October 13 and 17, 2024, of Landslides and Flooding Caused by Hurricane Helene (ver 1.1, March 2025)

This data release consists of geotagged oblique aerial photographs taken by U.S. Geological Survey (USGS) scientists to support landslide situational awareness following Hurricane Helene under mission assignment from the Federal Emergency Management Agency (FEMA). The data release is accompanied by a photo viewer map where select photos can be viewed interactively. The photographs were taken on October 13 and 17, 2024, from two helicopters flying simultaneously on both days. The team used three different camera models (Canon EOS 6D Mark II, iPhone 14 Plus, iPhone 15 Pro Max). Photos were taken primarily through an open window, but some were taken through a closed window or the windshield and may include glare or reflections. Flight paths, shown on Figure 1, were planned based on known areas of substantial landslide and flood activity, specific areas of concern relevant to the response, areas of high estimated hazard based on rainfall and landslide susceptibility, and sites not visited or well-visualized by earlier reconnaissance flights from fixed-wing aircraft.
