Title:
Benthic habitat map of the U.S. Coral Reef Task Force Watershed Partnership Initiative Kaanapali priority study area and the State of Hawaii Kahekili Herbivore Fisheries Management Area, west-central Maui, Hawaii
Abstract:
A benthic habitat polygon coverage has been created of the coral reef ecosystem within the U.S. Coral Reef Task Force Watershed Partnership Initiative Kaanapali priority study area and the State of Hawaii Kahekili Herbivore Fisheries Management Area, West-Central Maui, Hawaii. Polygons were hand-digitized from visual interpretation of QuickBird-2 satellite imagery (2005), and SHOALS bathymetry data. We also utilized in situ knowledge from underwater photography and videography (2002-2011), side-scan sonar data, and diver and snorkeler observations. The polygons have attributes for Main Structure/Substrate, Dominant Structure/Substrate, Major Biological Cover, Percent of Major Biological Cover, Reef Zone, Unique ID, and measurements of Area (in square meters) of each polygon.

Why was the data set created?

This mapping effort was carried out as a part of a U.S. Geological Survey effort to understand geologic processes of coral reef systems in the U.S. and its trust territories. It is intended to provide a baseline inventory of benthic habitat resources of the coral reef system within the U.S. Coral Reef Task Force Watershed Partnership Initiative Kaanapali priority study area and the State of Hawaii Kahekili Herbivore Fisheries Management Area, West-Central Maui, Hawaii for use by scientists, managers, and the general public. The data can be used with geographic information systems (GIS) software for research purposes.

  2. How were the data generated, processed, and modified?
    Date: 2013 (process 1 of 4)
    QuickBird-2 satellite imagery and SHOALS bathymetry data were used for the interpretation. These were loaded into ArcGIS 10.1 software, along with the NOAA Habitat Digitizer Extension. Additional field data used for the interpretation include sidescan-sonar data, and underwater digital video and photographs. Habitat boundaries were delineated directly into the digitally referenced GIS. Polygons were saved as a shapefile. Person who carried out this activity:

  3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    Vector polygon boundaries were delineated by interpretation of georeferenced QuickBird-2 satellite, SHOALS bathymetry data, sidescan-sonar data, and underwater video and photographs. The polygons were attributed using a modified version of the NOS/NOAA coral reef habitat digitizing extension for ESRI ArcGIS 10. Attributes are generated directly in the shapefile and errors are not expected. The shapefiles are free of topology errors. Overall accuracy of the major habitat classifications in these data is greater than 81%.
  2. How accurate are the geographic locations?
  3. How accurate are the heights or depths?
  4. Where are the gaps in the data? What is missing?
    Data are complete. Habitat boundaries are based on interpretation of digital imagery data of ground conditions at the time the imagery was collected. Polygon boundaries are subject to change over time.
  5. How consistent are the relationships among the observations, including topology?
    Digitizing was conducted using the "heads up" on screen method. Delineation of habitat boundaries is from interpretation of georeferenced QuickBird-2 satellite imagery, SHOALS bathymetry data, sidescan-sonar data, and underwater video and photographs. The digital imagery this interpretation is based on are believed to be logically consistent, although not tested.
