    • Nearshore Benthic Habitats of Timor-Leste Derived from WorldView-2 Satellite Imagery

    Metadata Updated: December 13, 2025

    Benthic habitat classes were derived for nearshore waters (< 20 m depths) around Timor-Leste from DigitalGlobe WorldView-2 satellite imagery, acquired from February 9, 2010 to December 14, 2013, by the NOAA Coral Reef Ecosystem Program (CREP). Habitat classes include soft (sand or mud) and hard (rubble, boulders, etc.) substrates by depth (shallow, mid and deep); seagrass, mangrove, and macroalgae dominated areas; intertidal zones; lagoons; and emergent rocks. Supervised classifications were performed using several different methods (maximum likelihood, and minimum distance) with imagery at several different stages of processing (deglinted, radiance, reflectance and deglinted, depth invariant, sieve, and clump), with final classification based on the classification method and imagery variant that provided the best overall results for each WorldView-2 image.

    Lineage Benthic habitat classes were derived for nearshore waters around Timor-Leste from WorldView-2 satellite imagery. Habitat classes include different combinations of shallow, mid and deep depths, soft (sand or mud) or hard (rubble, boulders, etc.) substrates, macroalgae, seagrass or mangrove dominated areas, intertidal areas, lagoons, and emergent rocks. Supervised classifications were performed using several different methods and with imagery at several different stages of processing, with final classification based on the classification method and imagery variant that provided the best overall results for each WorldView-2 image.
