1. General Description of Data to be Managed

1.1. Name of the Data, data collection Project, or data-producing Program:
Seafloor substrate (hard and soft bottom) maps derived from satellite imagery for the islands and atolls of the Pacific Remote Island Areas
1.2. Summary description of the data:

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.

5. Data Lineage and Quality

NOAA has issued Information Quality Guidelines for ensuring and maximizing the quality, objectivity, utility, and integrity of information which it disseminates.

5.1. Processing workflow of the data from collection or acquisition to making it publicly accessible
(describe or provide URL of description):

Lineage Statement:
Satellite images were processed for the Pacific Remote Island Areas using the method described in Mumby and Edwards (2000) and then, unsupervised classification was applied to derive Hard and Soft substrates. ENVI 5.3 (Harris Geospatial Solutions, Inc.) and ArcGIS 10.5.1 (Esri, Inc.) The lineage describes the general processing steps. The detailed steps and coefficients for each place are described in the readme file in the zip file.

Process Steps:

  • Worldview 2 or Worldview 3 satellite images are acquired through the NEXTVIEW Imagery License Agreement between DigitalGlobe, Inc. and National Geospatial Intelligence Agency (NGA). Under the agreement, the images are available for the use by the U.S. Government. Standard product level (2A) of multispectral and pancrhomatic images were acquired to produce hard soft maps. The images meeting the following criteria are carefully selected : cloud and shadow free, relatively small surf breaks, little sunglint on the water surface and little turbidity in the water.
  • The satellite images were preprocessed before generating the depth invariant indices using the tools available in ENVI 5.3. The images were first orthorectified using the RPC Orthorectification Workflow tool. The images are then radiometrically corrected and converted into the radiance using the Radiometric Calibration tool and Apply Gain and Offset tool. Radiometric calibration factors for each image are provided by DigitalGlobe in the associated metadata. The absolute calibration factors are available in the online documentation made available by DigitalGlobe. (Citation: Absolute Radiometric Calibration: 2016v0)
  • The atmospheric correction steps described in Mumby and Edwards (2000) were applied to the radiance images remove some of the atmospheric influences on the images. The calculation is sequenced in ENVI 5.3/IDL 8.5. (Citation: Mumby, P. J., Edwards, A. J. Water column correction techniques. In Remote Sensing Handbook for Tropical Coastal Management. Green, E. P., Mumby, P. J., Edwards, A. J., Clark, C.D., Eds. UNESCO: Parisk, France, 2000. Pp. 121-128. )
  • Depth Invariant Index in Mumby and Edwards (2000) were derived for 10 band pairs of each image. The band pairs are: Coastal - Blue, Coastal - Green, Coastal - Yellow, Coastal - Red, Blue - Green, Blue - Yellow, Blue - Red, Green - Yellow, Green - Red, Yellow - Red. Following equation was applied to each band pair using using the Band Math tool in ENVI 5.3 to derive the Depth Invariant Index. Depth Invariant Index of band pair i and j = Li -[(ki/kj)*Lj] where Li = Radiance or Reflectance values of band i Lj = Radiance or Reflectance values of band j ki/kj = Ratio of attenuation coefficients of band i and j Ratio of attenuation coefficients were derived in Excel spreadsheet using the variance and covariance of the radiance values extracted over shallow and deep sandy bottoms of each image. The results were exported as GeoTiff for the further analysis in ArcGIS. (Citation: Mumby, P. J., Edwards, A. J. Water column correction techniques. In Remote Sensing Handbook for Tropical Coastal Management. Green, E. P., Mumby, P. J., Edwards, A. J., Clark, C.D., Eds. UNESCO: Parisk, France, 2000. Pp. 121-128. )
  • The ISO Cluster Unsupervised Classification tool in ArcGIS 10.5.1 was employed to segment the depth invariant indices into multiple classes. Number of iterations were set to be 5, and minimum class size were set to be 3. Up to 15 classes were generated for each band pair of the depth invariant index. (Citation: Dove, D., Acoba, T., DesRochers, A. Seafloor Substrate Characterization from Shallow Reefs to the Abyss: Spatially-continuous seafloor mapping using multispectral satellite imagery, and multibeam bathymetry and backscatter data within the Pacific Remote Islands Marine National Monument and the Main Hawaiian Islands. 2018. PIFSC Internal Report IR-18-08. Issued 18 October 2018.)
  • Each band pair classification was visually examined by inspecting the cluster results against the substrate boundaries that can be identified in the original satellite images. The best band pair classification result detecting the substrate boundaries was chosen, and interpreters made an informed judgement in attributing the predicted classes into hard and soft. Where required, area-specific class attribution and minor manual editing were undertaken to remove inaccurate predictions in ArcGIS 10.5.1. Output file type is GeoTIFF. (Citation: Dove, D., Acoba, T., DesRochers, A. Seafloor Substrate Characterization from Shallow Reefs to the Abyss: Spatially-continuous seafloor mapping using multispectral satellite imagery, and multibeam bathymetry and backscatter data within the Pacific Remote Islands Marine National Monument and the Main Hawaiian Islands. 2018. PIFSC Internal Report IR-18-08. Issued 18 October 2018.)
  • Where multiple images are available, the same steps are applied to the second image, and the gaps of the classification result in the first image will be filled with the second image.
5.1.1. If data at different stages of the workflow, or products derived from these data, are subject to a separate data management plan, provide reference to other plan:
Always left blank
5.2. Quality control procedures employed
(describe or provide URL of description):

The method was developed initially for an area in West Hawaii where multiple sources of accurate, reliable data were available. Applying the method to islands in the Pacific Remote Island Areas, the process and resulting classifications were quality controlled by a group of team members before the products were finalized.
