The dataset was derived using multipectral World View-2 satellite data. Limited groundtruthing data are available for Ni'ihau Island and therefore we are unable to evaluate the accuracy of the supervised classification seafloor substrate map. The hard and soft seafloor map is being used to improve sampling techniques for long-term ecosystem monitoring, to guide future ground-truthing operations and to identify coral-rich and species specific environments. This is a preliminary product and the methods used to generate the map are currently being evaluated for their accuracy.

The pre-processed and de-glinted image was loaded into ENVI 4.8.software. Six different types of regions of interest (ROI's) were created in ENVI 4.8. The ROI's are classified as followed: 1. shallow soft/sand 2. medium deep soft/sand 3. deep soft/sand 4. shallow hard 5. medium deep hard 6. deep hard The Image classification was performed seperately on the multi-band image using three different methods. The MahalanobisDistance Classification, which is a direction sensitive distance classifier. J.A.Richards, 1999, Remote Sensing Digital Image Analysis, Springer-Verlag, Berlin, p. 240. The Maximum Likelihood Distance, which assumes that the statistics for each class in each band are normally distributed and the Minimum Distance, which uses the mean vectors for each class and calculates the distance from ech unknowkn pixel the the mean vector for ech class. More information about the MahalanobisDistance, Maximum LiklihoodDistance and the Minimum Distance algorithm can be found in the ENVI documentation available at http://www.exelisvis.com/ProductsServices/ENVI/ENVI.aspx. THe results of each of the three classifications were compiled into an ENVI standard image. The outputs were exported in a geotiff format and loaded in ArcGIS 10.1. All land and NoData values were removed using the Arc10.1 toolbox "extracting by mask" tool. The outputs were the same six classes as previously when creating the ROI's. THe results were reclassified using the Arc10.1 toolbox into "hard" and "soft" classes only. 2013-03-10T00:00:00 otherRestrictions Metadata Access Constraints: None otherRestrictions Metadata Use Constraints: None annually This metadata was automatically generated from the FGDC Content Standards for Digital Geospatial Metadata standard (version FGDC-STD-001-1998) using the 2016-01-11 version of the FGDC RSE to ISO 19115-2 transform.
