Nearshore benthic habitats of Timor-Leste derived from WorldView-2 satellite imagery from 2010-02-09 to 2013-12-14 (NCEI Accession 0168914)

browse graphicPreview graphic
Benthic habitat classes were derived for nearshore waters (< 20 m depths) around Timor-Leste from DigitalGlobe WorldView-2 satellite imagery, acquired from Jan 26 2010 to Aug 10, 2014, 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.

CMW43B Abstract:
Inventory of satellite images from DigitalGlobe’s WorldView-2 satellite purchased by the NOAA Coral Reef Ecosystem Program for Timor-leste from Jan 26, 2010 to August 10, 2014. Images were acquired for purposes of deriving seafloor depths and benthic habitat classes for the nearshore waters (< 20m depths) of Timor-leste. In addition to the inventory, the dataset includes the regions of interest (ROI) defined by NOAA used to define the geographic areas to acquire the satellite images from DigitalGlobe, the boundary extent of the available images within each ROI, and the footprint (extent) of each image. The data within each satellite image is clipped to the ROI. The ROI, boundary, and footprint files are provided in shapefile format, and the inventory is provided as a text file, which corresponds to the footprints shapefile.
Purpose In 2011, NOAA and the United States Agency for International Development (USAID) Timor-Leste Mission formed a 5-year bi-lateral partnership agreement from 2012 to 2016, in support of the Government of Timor-Leste—particularly the Ministry of Agriculture and Fisheries (MAF)—by addressing significant information gaps in their nearshore marine ecosystems. Specifically, MAF asked NOAA to address the following questions: 1. Where are the nearshore marine resources? 2. What are the nearshore marine resources? 3. How are they changing over time and what threats are potentially causing these changes? 4. What approaches are needed to manage and conserve the nearshore marine resources? With financial support from USAID and in-kind support from the NOAA Coral Reef Conservation Program (CRCP), the NOAA Coral Reef Ecosystem Program (NOAA-CREP) conducted baseline ecosystem assessment surveys to inform ecosystem-based management planning in Timor-Leste. The primary activities conducted by NOAA to answer these questions included: 1. satellite mapping of nearshore habitats, 2. conducting coral reef ecosystem assessments, 3. establishing ecological baselines for climate change, and 4. building management capacity by developing a spatial data framework The benthic habitat classification data described herein resulted from the first activity to conduct satellite mapping for the nearshore waters around Timor-Leste.
