Item Identification

Title: 2009 C-CAP Land Cover, Territory of American Samoa, Rose Atoll
Short Name: 2009_era_as_rose_atoll_landcover
Status: Completed
Publication Date: 2013-08-15
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 1 full or partial 2009 WorldView2 multispectral scene and the 2002 high-resolution Rose Atoll, American Samoa C-CAP data set. The imagery and base classification were included in a multi-step change detection process to extract land cover features in the 2009 imagery.

Purpose:

To improve the understanding of coastal uplands and wetlands, and their linkages with the distribution, abundance, and health of living marine resources.

Data Quality

Accuracy:

None.

Horizontal Positional Accuracy:

<3.5 meters CE90

Vertical Positional Accuracy:

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

Completeness Report:

Data does not exist for all classes.

On Rose Atoll 6 classes exist; 8 (Grassland/Herbaceous), 10 (Evergreen Forest), 12 (Shrub), 19 (Unconsolidated Shore), 20 (Barren), 21 (Water).

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: 628129
Description:

This data set was created by Photo Science Inc. (www.photoscience.com).

This version of the classification is the High Resolution Land Cover (2009-era) for Rose Atoll, American Samoa.

This section outlines the classification procedure for Rose Atoll, American Samoa High Resolution C-CAP. Non-impervious features were mapped using a 0.25 acre minimum mapping unit (MMU) and impervious features were mapped using a 0.1 acre MMU.

Pre-processing steps:

The WorldView2 imagery utilized for this project was provided from Digital Globe as an orthorectified, georeferenced product. Photo Science geo-referenced the 2002 C-CAP classification and the 2002 base imagery to the WorldView2 (as it has better horizontal accuracy) to co-register the data sets.

Classification:

The 2002 C-CAP classification was overlaid on the 2009 WorldView2 imagery with a semi-transparency. The classification was systematically reviewed at a scale of 1:2,500. Where land cover changes were identified the analyst would zoom into a larger scale and manually edit the map to reflect the 2009 ground conditions. The updated map then went through an independent review to further refine the classification. Image segmentation was run on the 2009 imagery in a buffered zone around all of the changed areas. The updated land cover was summarized by the image objects (segments) to replace hand delineated boundaries with boundaries based on image segmentation. This final step ensured a consistent look and feel across the high resolution C-CAP data sets.
