High Resolution Orthomosaics and DEMs produced from UAS imaging of sites in Turtle Creek, Union County, Pennyslvania

June 16, 2026

This landing page provides the high resolution orthomosaics and digital elevation models (DEMs) produced from UAS imagery of 3 sites along Turtle Creek, in Union County, Pennyslvania. Each of the 3 sites was imaged during leaf-off season in 2020/2021 (Flight 1) and in 2022/2023 (Flight 2). Structure-from-motion processing of the collected imagery in Agisoft Metashape software (v. 2.1.1) produced a high-resolution orthomosaic and DEM for each flight. These data products can be accessed via the child links below.  See metadata for indvidual files for detailed processing methods.
