Item Identification

Title: C-CAP Land Cover, Kauai, Hawaii 2005
Short Name: 2005_hawaii_ccap_hr_lc
Status: Completed
Publication Date: 2015-01-22
Abstract:

This data set consists of land derived from high resolution imagery and was analyzed according to the Coastal Change Analysis Program (C-CAP) protocol to determine land cover. This data set utilized Quickbird multispectral scenes which were processed to detect C-CAP land cover features on the coastal areas of the Big Island of Hawaii. Due to the size of the area mapped and the frequency of cloud cover across the region dates of the Quickbird scenes ranged from early 2002 to early 2009. Imagery was selected for least cloud cover, overall quality and most recent date possible.

Purpose:

To create a baseline inventory of land cover features which can be utilized by state and local resource managers.

Data Quality

Accuracy:

No attribute accuracy has been determined for this dataset.

Horizontal Positional Accuracy:

12 meters CE90

Vertical Positional Accuracy:

There was no terrain correction in the geo-referencing procedure.

Completeness Report:

Data does not exist for all classes.

There are no pixels representing class 9 (Deciduous Forest), class 11 (Mixed Forest), class 23 (Estuarine Aquatic Bed), 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 Developed, High Intensity (Class 2).

Conceptual Consistency:

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.

Process Steps

Process Step 1

CC ID: 627581
Description:

This dataset was created by Sanborn (www.sanborn.com) and MDA Information Systems (www.mdafederal.com).

This version of the classification is the High Resolution Land Cover (2005-era) for the Island of Hawaii, HI. Sanborn mapped land cover for the exterior (coastal zone) of the Big Island while MDA Federal mapped the interior.

Summary:

This section outlines the classification procedure for the Island of Hawaii 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 conducted by Sanborn and NOAA OCM staff. Non impervious features were mapped using a 0.5 acre minimum mapping unit (MMU).

Pre-processing steps:

The Quickbird imagery 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 imagery, Sanborn used ancillary IKONOS imagery from 2002-2003, and aerial Emerge imagery, 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 collected between January 18, 2009 and January 23, 2009 by Sanborn and NOAA OCM staff.

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 for the entire island and an iterative nearest neighbor classifier in Definiens software for certain sections. 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 compilation and edge matching - Sanborn's and MDA Federal's maps were edge matched by NOAA OCM through a combination of spatial modeling and manual editing to create a wall-to-wall land cover product.

Post processing - The change detection process used to create the 2010 Hawaii 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.
