North American Coastal Plain PRISMA Surface Reflectance and Mixture Residual Spectra

The data available here include the training and validation spectra for creating the models for the currently unpublished manuscript “Classifying Plant Communities in the North American Coastal Plain with PRISMA Spaceborne Hyperspectral Imagery and the Spectral Mixture Residual." Spectral data contain both raw surface reflectance (SR) and spectral mixture residual spectra (MR) transformed with endmembers and code from Sousa et al.'s (2022) paper titled "The spectral mixture residual: A source of low‐variance information to enhance the explainability and accuracy of surface biology and geology retrievals." Spectra represent averaged 60 m x 60 m areas (2 x 2-pixel window) located in the Red Hills (RH), the Jones Ecological Research Center (JERC), the Ordway-Swisher Biological Station (OSBS), and the Disney Wilderness Preserve (DSNY). To maintain the confidentiality of private property information on behalf of landowners, the locations of the RH plots were intentionally obscured, considering the nature of the region. See manuscript for further details.
