This data set consists of land cover derived from high resolution imagery according to the Coastal Change Analysis Program (C-CAP) protocol. This data set utilized 1 full Quickbird multispectral scenes which were processed to detect C-CAP land cover features on the island of Niihau.
To improve the understanding of coastal uplands and wetlands, and their linkages with the distribution, abundance, and health of living marine resources.

No report is available.
Tests for logical consistency indicate that all row and column positions in the selected latitude/longitude window contain data. Conversion and integration with vector files indicates that all positions are consistent with earth coordinates covering the same area. Attribute files are logically consistent.
Data does not exist for all classes.
There are no pixels representing class 24 (Tundra), 25 (Perennial Ice/Snow), 26 (Dwarf Scrub - Alaska specific class), 27 (Sedge/Herbaceous), and 28 (Moss - Alaska specific). Developed classes have been altered to exclude the percentage breakdown of impervious surfaces as the breakdown is not appropriate for high resolution mapping (Developed High Intensity (2), Developed Medium Intensity (3), and Developed Low Intensity (4) are reduced to Impervious Surfaces (Class 2)). Mixed Forest (11) was also determined not be appropriate for this map since no mixed pixels existed at this spatial resolution.

This dataset was created by Sanborn (www.sanborn.com). This version of
the classification is the High Resolution Land Cover (2005-era) for the
Island of Niihau, HI.
Summary:
This section outlines the classification procedure for the Niihau High
Resolution C-CAP. Quickbird imagery used in producing this land cover
product was also utilized in producing an associated impervious surfaces
layer for the island. The mapping approach utilized an object oriented
approach. A calibration visit was not conducted. Non impervious features
were mapped using a 0.5 acre minimum mapping unit (MMU).
Pre-processing steps: The Quickbird mosaic utilized for this project was
provided from Digital Globe as an orthorectifed, georeferenced product
and was consistent with the quoted 1:12000 spatial accuracy. In
conjunction with the Quickbird mosaic, Sanborn used an IKONOS mosaic, as
well as a DTM created from a 5m radar collect for the island. The
original return image from the radar was also utilized.
Field-Collected Data: Training data was not collected.
Classification: Segmentation - Image segmentation was completed at
multiple scales using the multispectral (2.4 m) imagery in order to
group like spectral and textural objects within the imagery. For
consistency, the associated impervious data set was incorporated into
the segmentation layer as a boundary delimiter. Segments can share
boundaries of an impervious surface, but can never overlap an impervious
surface.
Automated Classification, image segments are classified using a decision
tree classifier in See5 software and an iterative nearest neighbor
classifier in Definiens software. Nearest neighbor training data is
collected through analyst interpretation or ancillary data sets and used
to calibrate the classification algorithm.
Automated Classification Refinement - Models are built to refine or
reclassify land cover areas by utilizing the wealth of attribute
information linked to each segment within Definiens.
Classification Edits - As with any automated or semi-automated land
cover classification there are often inconsistencies in the land cover
map. The final step before map finalization was to remove inaccuracies
through manual segment labeling as interpreted by an analyst.
Map Finalization - Sanborn used independent reviewer's comments to
further refine the land cover map.
Post processing:
The change detection process used to create the 2010 Niihau C-CAP product highlighted some errors in the 2005 land cover map. To create a more accurate product these issues we addressed by NOAA through a combination of spatial models and manual edits. While the changes may not be large in area and/or be directly reflected in the accuracy assessment, we feel the products more accurately reflect the land cover for the time period.
