| Survey Equipment | Survey Info | Data Type(s) | Data Collected |
|---|---|---|---|
| Structure from Motion - UAS | --- | Photo | Aerial images from a UAS survey of the debris flow at South Fork Campground, Sequoia National Park, CA (This portion of the data release presents aerial images of the debris flow at South Fork Campground in Sequoia National Park. The images were acquired during an uncrewed aerial systems (UAS) survey on 30 April 2024, conducted under authorization from the National Park Service.) Aerial video acquired during the UAS survey of the debris flow at South Fork Campground, Sequoia National Park, CA (This portion of the data release presents aerial video acquired during the uncrewed aerial systems (UAS) survey of the debris flow at South Fork Campground in Sequoia National Park, conducted under authorization from the National Park Service. The video shows low-altitude oblique and nadir perspectives of the lower 1.3 kilometers of the debris flow. The video is being included as part of the data release to provide additional context for the geohazards assessment of the area.) Digital Surface Model (DSM) from UAS survey of the debris flow at South Fork Campground, Sequoia National Park, CA (This portion of the data release presents a high-resolution Digital Surface Models (DSM) of the debris flow at South Fork Campground in Sequoia National Park. The DSM has a resolution of 10 centimeters per pixel and was derived from structure-from-motion (SfM) photogrammetry using aerial imagery acquired during an uncrewed aerial systems (UAS) survey on 30 April 2024.) Orthomosaic imagery from the UAS survey of the debris flow at South Fork Campground, Sequoia National Park, CA (This portion of the data release presents a high-resolution orthomosaic image of the debris flow at South Fork Campground in Sequoia National Park. The orthomosaic has a resolution of 3 centimeters per pixel and was derived from structure-from-motion (SfM) photogrammetry using aerial imagery acquired during an uncrewed aerial systems (UAS) survey on 30 April 2024.) Topographic point cloud from UAS survey of the debris flow at South Fork Campground, Sequoia National Park, CA (This portion of the data release presents a topographic point cloud of the debris flow at South Fork Campground in Sequoia National Park. The point cloud was derived from structure-from-motion (SfM) photogrammetry using aerial imagery acquired during an uncrewed aerial systems (UAS) survey on 30 April 2024.) |
