High-Resolution UAS-Based Optical and Thermal Infrared Imagery and Geospatial Data from Surveys of four Lake Ontario Tributaries, New York

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: August 25, 2025 | Last Modified: 20250708
This data release contains geospatial datasets that identify thermal zones across multiple reaches of four tributaries to Lake Ontario: St. Regis River, Salmon River, South Sandy Creek, and Sandy Creek. High-resolution uncrewed aircraft system (UAS)-based optical and thermal infrared imagery and ground level field observations are included. Shapefiles for each tributary reach identify thermal zones that are three, five, ten, and fifteen percent different than a reference temperature calculated as a mean along the approximate centerline of each reach. These data are accessible as an online webmap: https://ny.water.usgs.gov/maps/thermalrefugia
