Popis

Aerial photographs taken by NOAA's National Geodetic Survey during 1977 and 1971 were mosaicked and orthorectified by the Biogeography Branch resulting in a single composite mosaic of both years of photography. The resulting image was used to digitize benthic, land cover and mangrove habitat maps of the Salt River Bay National Historic Park and Ecological Preserve (National Park Service), on St. Croix, in the U.S. Virgin Islands. The composite, rather than a single year mosaic, was used because the northward extent and water clarity of photos from any single year were inadequate for the project objectives. The mosaic is centered on the National Park Service Site, located on the north central coast of St. Croix, and extends beyond the park boundaries approximately 3 km to the south, 6 km to the west, 4.5 km to the east, and 0.5 km to the north.
