Ortho Seam Lines with Photo Exposure Dates - 2024 Imagery

In 2024, on behalf of the NC Center for Geographic Information and Analysis five contractors captured 6-inch pixel 4 band true color plus NIR ortho imagery for the 27 Coastal Counties in NC (CO24). This file documents the mosaic of imagery exposures and associated seamlines used to generate the countywide collection of imagery in all Study Areas. Seamlines were combined from each study area allowing for smooth transitions between each exposure frame. For the Surdex Corporation seamlines, the exposures have a value of 0.
