Description:

Abstract:

This project is a cooperative effort between NOAA's National Centers for Coastal Ocean Science (NCCOS), U.S. Geological Survey, National Park Service, and the National Geophysical Data Center, to produce benthic habitat maps and georeferenced imagery for the U.S. Virgin Islands. This project was was conducted in support of the U.S. Coral Reef Task Force.

Purpose:

This project was conducted in support of the U.S. Coral Reef Task Force.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Thematic accuracy was determined by comparison to field points and found to be 94% overall.

Logical_Consistency_Report:

Polygons were delineated directly from orthophotos directly into a GIS using ArcView. Attribution of polygon types was accomplished in ArcView as well. A careful review of the finished polygon coverage was done to ensure that all labels were compete and accurate.

Completeness_Report:

Data is complete. All interpretable habitats were mapped and peer reviewed by a panel of local experts familiar with the project area.

Source_Contribution:

Benthic features were interpreted and mapped from NOS aerial photos

Process_Step:

Process_Description:

Ground control points, camera calibration data, and USGS DTM data were used to orthorectify 500 dpi scans of the aerial photos using Socet Set Version 4.2.1. Orthorectified images were then loaded into ArcView 3.2 with the Image Analyst and Habitat Digitizer Extensions activated. This allowed the photointerpreter to interpret features, delineate and attribute benthic habitat directly into a digital reference system. The data were saved as ArcView shapefiles.
