Item Identification

Title: 2006 C-CAP Land Cover, Territory of American Samoa, Rose Atoll
Short Name: 2006_era_AS_Rose_Atoll_landcover
Status: Completed
Publication Date: 2009-12-17
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 which utilized 1 full Quickbird multispectral scene and 1 full or partial 2009 WorldView2 multispectral scene, was analyzed to detect C-CAP land cover features on Rose Atoll, American Samoa.

Purpose:

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

Data Quality

Accuracy:

None.

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.

On Rose Atoll 4 classes exist; 10 (Evergreen Forest), 12 (Shrub), 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.

CC ID: 627799
Description:

This dataset was created by Sanborn (www.sanborn.com).

This version of the classification is the High Resolution Land Cover (2006-era) for the Island of Rose Atoll, American Samoa.

This section outlines the classification procedure for the Island of Rose Atoll, American Samoa High Resolution C-CAP. Quickbird imagery used in producing this land cover was segmented in like objects and classified. A calibration visit was not conducted. Non impervious features were mapped using a 0.25 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.

Classification:

Segmentation - Image segmentation was completed at a single scale using the multispectral (2.4 m) imagery in order to group like spectral and textural objects within the imagery.

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.
