This living resources information focuses on marine and estuarine benthic habitat data. The geographic domain is nearshore, intertidal, and subtidal areas. Some benthic cover data are comprehensive and capture all detectable resources within a study area, while others focus on a specific feature or habitat type such as seagrasses or oyster reefs. Most data are derived from raster imagery sources such as aerial multispectral imagery or acoustic backscatter. The collection also includes point data collected from single-beam acoustic sensors, which capture benthic habitat information along transects.
