The U.S. Geological Survey collected low-altitude airborne natural color imagery via a fixed-wing uncrewed aircraft system (UAS) for mapping channel and vegetation change along a 2-mile reach of the Middle Green River at Grays Canyon near Green River, UT. Visual imagery was collected in jpg format and Structure-from-Motion (SfM) photogrammetry techniques were applied (Over et. al. 2021) using Agisoft Metashape Professional (v. 2.1.2 build 18358) to derive time-specific high-resolution 5 centimeter natural color orthomosaics of the study reach annually from 2021 to 2023. Ground control points (2ft x 2ft ground targets) were also surveyed in the field using Trimble RTK GPS survey units and were used in georectification in the SfM process.

The U.S. Geological Survey collected low-altitude airborne natural color imagery via a fixed-wing uncrewed aircraft system (UAS) for mapping channel and vegetation change along a 6-mile reach of the Middle Green River at Ouray National Wildlife Refuge near Ouray, UT.

These digital images were taken over an area of the Potomac River in Point of Rocks, Maryland using 3DR Solo unmanned aircraft systems (UAS) on October 24, 2019. These images were collected for the purpose of evaluating UAS assessment of river habitat data such as water depth, substrate type, and water clarity. Each UAS was equipped with a Ricoh GRII digital camera for natural color photos, used to produce digital elevation models and ortho images. Some photographs contain black and white targets used as ground control points (GCPs), which were surveyed by a field crew with a high-precision (GNSS) Global Navigation Satellite System and/or containing internal post processing kinematic (PPK) GPS system. This data release includes the original true color images from the Ricoh GRII digital camera of the Potomac River in Point of Rocks, Maryland.

The U.S. Geological Survey (USGS) National Uncrewed Systems Office (NUSO) supported the USGS National Cooperative Geologic Mapping Program’s Geoheritage Sites of the Nation Project in July of 2024 with the collection of UAS-based high-resolution imagery of the Marsh-Felch Quarry site at the Bureau of Land Management (BLM) Garden Park Fossil Area. One of the most complete dinosaur skeletons ever unearthed was found here. These discoveries around present-day Garden Park Fossil Area sparked the “Bone Wars” of the late 1800s and inspired the selection of Colorado's state fossil, the Stegosaurus. Three-dimensional (3D) scan flights were conducted at the fossil site using a Skydio X10 UAS, in which the aircraft autonomously determined where to capture photos to achieve coverage across a volume of interest. The natural color UAS images were processed in photogrammetry software to generate a 3D model of this fossil site for inclusion in the Geoheritage web application. A two-dimensional (2D) mapping scan with the Skydio X10 UAS flown at 300 feet above ground level was also conducted to capture the topography of the surrounding area. This portion of the data release presents raw natural color images collected during the 2D mapping flights over the fossil site. Over the course of one 21-minute flight, a Skydio X10 UAS with an integrated VT300-Z Narrow sensor mapped a 36,483 square meter area and captured 456 natural color red, green, blue (RGB) photos to achieve 75% overlap and 75% sidelap. The images are provided here in a zip file to facilitate bulk download. Structure-from-motion (SfM) Digital Surface Model (DSM) and Orthomosaic data products were generated by processing these 2D Mapping images in photogrammetry software. These data products are provided here in .tif format zipped with supporting files. These DSM and orthomosaic data products were generated for visualization of the environment surrounding the quarry site.
