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

Description

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.

Benthic_Habitat_Timor.zip Unknown GeoTiff raster benthic habitat data for nearshore waters of Timor Leste, based on a supervised classification of WorldView-2 satellite imagery. The benthic habitat data are organized by region (north shore, south shore, Atauro Island, and Oecusse), and each region contains 1) the individual final benthic habitat files (one geoTiff for each satellite image), 2) a projected (UTM_Zone_51S) benthic habitat mosaic for the region, and 3) an unprojected (WGS84) mosaic for the region. The mosaics are also in geoTiff format. An ESRI layer file is included within each region folder for ease of displaying the geoTiffs in ESRI's ArcGIS software. The symbology is based on the VALUE field and defined by the corresponding class. Open resource
Benthic_Habitat_Final_TIF_Metadata.csv Unknown Metadata information for each final benthic habitat geotif produced for the four regions (north shore, south shore, Atauro Island, and Oecusse) in Timor-Leste. Metadata file includes source satellite image name, and identifies the specific layer used for benthic classification, the supervised classification type, and any post-processing methods used.
