Item Identification

Title: C-CAP Land Cover, United States Virgin Islands, St. John, 2012
Short Name: usvi_stjohn_2012_ccap_hr_land_cover
Status: Completed
Publication Date: 2015-01-30
Abstract:

This data set consists of land cover 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 CIR imagery captured from a Z/I Imaging DMC-II 230 (2012 flights) digital sensor. The land cover is based on the 2007 high resolution St. John C-CAP dataset. Changes were identified using aerial photo interpretation of the 2007 dataset against the 2012 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:

TO BE ADDED BY NOAA

Horizontal Positional Accuracy:

< 10.7 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 11 (Mixed Forest), 22 (Palustrine Aquatic Bed), 23 (Estuarine Aquatic Bed), 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 (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: 631768
Description:

This data set was created by Dewberry (www.dewberry.com). This version of the classification is the High Resolution Land Cover (2012-era) for the Island of St. John, United States Virgin Islands.

This section outlines the classification procedure for the St. John High Resolution C-CAP. The color-infrared imagery used in producing this land cover product was also utilized in producing an associated impervious surfaces layer for the island. This land cover is based on the 2007 high resolution St. John C-CAP dataset. Changes were identified using aerial photo interpretation of the 2007 dataset against the 2012 imagery. A calibration visit was not conducted though NOAA had access to local resources for validation. 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 2012 color-infrared imagery utilized for this project was provided from the USACE as an orthorectified, georeferenced product. The imagery was reviewed for radiometric errors, pixel dropouts, and other image issues. Individual image tiles were merged into a single mosaic and re-sampled from the native 1-foot spatial resolution to 1m.

Classification:

The 2007 C-CAP dataset was over-laid with semi-transparency on the 2012 color-infrared imagery. It was panned at a scale of 1:5,000 and manually updated to match features in the 2012 imagery. Analysts zoomed in to a larger scale when necessary to perform edits. The product went through a QC procedure to ensure features were accurately captured.

Map Finalization - Dewberry used independent reviewer's comments to further refine the land cover map.
