South Atlantic Landscape Conservation Cooperative(administrator), Tom Allen(Principal Investigator), 2017-02-28(Publication), Normalized Difference Index (NDX) Mosaic Composite for SALCC Salt Marshes,


Data set includes a mosaic of multiple Landsat 8 OLI sensor path/row combinations for May 14, 17, and 19, 2014 covering the South Atlantic Landscape Conservation Cooperative (SALCC) geography between extreme northeastern North Carolina (including Back Bay, VA-NC) south through Sapelo I., GA. The imagery was acquired as georeferenced, calibrated digital data. Water and upland masking used NIR thresholds, CCAP land cover, and LiDAR DEMs. The image composite includes three normalized difference indces useful for marsh classification and monitoring, including: 1) Normalized Difference Vegetation Index (NDVI), 2) Normalized Difference Water Index (NDSI), and 3) Normalied Difference Soil Index (NDSI). The NDX bands were regionally classified [...]

The NDX composites were derived from Landsat 8 for classifying salt marshes of the SALCC into improved, thematic compositional information clases (versus land cover or strictly physiognomic classes). Salt marsh zonation is evident in the multispectral NDX color space and provided discrimination for OBIA clasification.


None. Please see 'Distribution Info' for details.; None. Users are advised to read the data set's metadata thoroughly to understand appropriate use and data limitations.; Distributor assumes no liability for misuse of data.
