Seafloor substrate (hard and soft bottom) maps derived from satellite imagery for the islands and atolls of the Pacific Remote Island Areas

Description

Seafloor substrate (i.e., hard vs. soft bottom) from 0 to up to 30 m depths around islands/atolls in Pacific Remote Island Areas produced by the NOAA Ecosystem Sciences Division (ESD). The islands/atolls include Howland, Baker, Jarvis, Kingman Reef, Palmyra Atoll, Johnston Atoll, Wake Atoll. This is a preliminary product derived from an unsupervised classification of depth-invariant indices prepared from high resolution satellite images. Unsupervised classification segmented the indices into multiple classes, and the binary substrate map was produced by mapping interpreter's informed judgments in attributing the predicted classes. Where required, area-specific class attribution and minor manual editing were undertaken to remove inaccurate predictions.
