Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Uncrewed Aircraft Systems (UAS) natural color imagery and structure-from-motion data products collected at the Marsh-Felch Dinosaur Quarry site in Colorado, July 2024 Uncrewed Aircraft Systems (UAS) natural color imagery and structure-from-motion data products collected at the Marsh-Felch Dinosaur Quarry site in Colorado, July 2024
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...
Satellite images used to test a sundial method for inferring image acquisition time from shadow orientation Satellite images used to test a sundial method for inferring image acquisition time from shadow orientation
This data release provides satellite images used to test a method for inferring image acquisition time from shadow orientation. For many applications, such as linking remotely sensed data to streamflow recorded at a gaging station, knowing the time an image is acquired is important, but such metadata often is not available. The sundial method is a simple means of inferring image...
Image-based measurements and gage records used to test a method for inferring river discharge from remotely sensed data based on critical flow theory Image-based measurements and gage records used to test a method for inferring river discharge from remotely sensed data based on critical flow theory
This data release makes available the data used to test a method for remote sensing of river discharge based on critical flow theory. In rivers where flow conditions are near critical and well-defined standing waves are present, simple measurements of the wavelengths of the standing waves and the width of the channel made using readily available image data can be used to infer river...
Wake Atoll yellow crazy ant survey, 2023 (ver. 2.0, October 2024) Wake Atoll yellow crazy ant survey, 2023 (ver. 2.0, October 2024)
This data release includes metadata and tabular data that documents the distribution of yellow crazy ants (Anoplolepis gracilipes) across Wake Atoll. The three islands that comprise the atoll were systematically searched by hand. The dataset describes the outcome of searching 3,675 cells, each 50 x 50 m in size, during 6-21 October 2023. .
Digital Surface Model of the Lost River Fault, Idaho, from 1966 Aerial Photographs Digital Surface Model of the Lost River Fault, Idaho, from 1966 Aerial Photographs
This data release contains a point cloud and raster image of a digital surface model (DSM) that covers a portion of the Lost River fault in Idaho that ruptured in the 1983 M6.9 Borah Peak earthquake. The DSM provides a high-resolution, pre-earthquake record of the landscape from 1966. It is constructed using structure-from-motion photogrammetry software and aerial photographs taken in...
Data on Exposure of Wild Mammals Inhabiting Alaska to H5N1 Influenza A Viruses Data on Exposure of Wild Mammals Inhabiting Alaska to H5N1 Influenza A Viruses
This data set describes serological data collected from mammals in Alaska and seropositivity to influenza A, clade 2.3.4.4b H5 highly pathogenic avian influenza (HPAI), North American lineage H5 low pathogenic avian influenza (LPAI), and N1 antigens.
