Abstract:
The data results show for the first time Landsat-based land use maps of both the terrestrial and benthic habitats of the U. S. Virgin Islands, spanning a period of 16 years (1985 to 2001). Shallow-water (generally, less than 30 meters) bank and land areas on St. Thomas, St. John, and St. Croix were identified through unsupervised classification of Landsat 7 TM and ETM+ satellite imagery. NOS aerial photographs, benthic habitat data, and bathymetric data were used to ground truth the scenes. The project was supported through the Coral Reef Conservation Program.

Purpose:
The objective was to evaluate the effectiveness of Landsat as a potential tool for monitoring the long-term impact of sedimentary runoff to benthic ecosystems. The terrestrial portions of the scenes showed a major shift from forest cover to rural and urban land use. The benthic areas showed a shift from live to dead-algae-covered coral. While the findings cannot establish a causative link between change in land use and decline in coral ecosystem health, they suggest that Landsat may serve as an effective tool when allocating resources for further analysis, habitat conservation, or protection.

Data_Quality_Information:
Logical_Consistency_Report:
Multispectral Landsat satellite imagery was positioned using ground control data points collected with Garmin GPS and with ground control points from NOS Aerial Photographs .
Completeness_Report:
Landsat imagery over deep water and cloud-covered pixels has been removed.

The results were more conclusive for St. Croix than for St. John, which were smaller in size and had a greater amount of cloud cover than St. Croix.

The classification accuracy was improved by removing all areas greater than approximately 9 m in depth from the classification. This was due to the fact that, in clear water, Landsat TM and ETM+ sensors are unable to discriminate spectral signatures of objects greater than approximately 9 m in depth.

Moderate-resolution Landsat satellite imagery was analyzed to produce land use maps of terrestrial and shallow-water habitats in the USVI.
Process_Step:
Process_Description:
The observation dates of LandSat imagery used ranged from 1985 through 2001. Image processing and analysis were carried out on USVI Landsat images from five dates that spanned a total of 16 years. All scenes had Level 1G radiometric and systematic geometric correction to 250 m based on Landsat payload correction data files and radiometric correction based on the pre-launch calibration of the sensor's reflective band detectors

Using the visible shallow water extent as a guide, each of the georectified shallow water areas and atolls were clipped from the Landsat ETM+ imagery. In another set of scenes, all water areas were clipped, leaving only terrestrial areas. They were atmospherically corrected, and using unsupervised classification, land use and change maps were created for the benthic and terrestrial portions of each scene.

Because water and land have spectral characteristics very different from one another, the benthic and terrestrial portions of each satellite image were classified separately.
