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. Purpose: The image was used to create benthic and mangrove habitat maps of the Salt River Bay National Historic Park and Ecological Preserve. The maps support current and future monitoring and management efforts at the site, and support programmatic objectives of the NPS service-wide Inventory and Monitoring Program. In addition to the habitat maps, the georeferenced image may by utilized by the park to examine other resource management issues, including development, deforestation, erosion, etc. Time_Period_of_Content: Time_Period_Information: Multiple_Dates/Times: Single_Date/Time: Calendar_Date: 19711120 Single_Date/Time: Calendar_Date: 19771207 Currentness_Reference: ground condition Status: Progress: Complete Maintenance_and_Update_Frequency: None planned Spatial_Domain: Bounding_Coordinates: West_Bounding_Coordinate: -64.819247 East_Bounding_Coordinate: -64.694612 North_Bounding_Coordinate: 17.806403 South_Bounding_Coordinate: 17.729013 Keywords: Theme: Theme_Keyword_Thesaurus: NCEI Geoportal Filter Theme_Keyword: CoRIS_Metadata Theme: Theme_Keyword_Thesaurus: CoRIS Theme Thesaurus Theme_Keyword: EARTH SCIENCE > Biosphere > Zoology > Corals > Reef Monitoring and Assessment > Photographic Analysis Theme_Keyword: EARTH SCIENCE > Biosphere > Zoology > Corals > Reef Monitoring and Assessment > Remote Sensing Theme_Keyword: EARTH SCIENCE > Biosphere > Zoology > Corals > Reef Monitoring and Assessment > Remote Sensing > Aircraft > Aerial Photography Theme: Theme_Keyword_Thesaurus: CoRIS Discovery Thesaurus Theme_Keyword: Map Images > Aerial Photographs Theme: Theme_Keyword_Thesaurus: None Theme_Keyword: Coastal Ecosystem Science Theme: Theme_Keyword_Thesaurus: ISO 19115 Topic Category Theme_Keyword: environment Theme_Keyword: 007 Place: Place_Keyword_Thesaurus: CoRIS Place Thesaurus Place_Keyword: OCEAN BASIN > Atlantic Ocean > Caribbean Sea > Virgin Islands > St. Croix > Salt River Bay (17N064W0022) Place_Keyword: COUNTRY/TERRITORY > United States of America > U.

Geometry appears topologically clean. Completeness_Report: The composite 1971/1977 mosaic, rather than a single year mosaic, was used because the northward extent and water clarity of photos from any single year were inadequate for overall mapping objectives. Accordingly, areas within the following approximate bounding coordinates originated from 1977 imagery: NE: lon: -64.73161 lat: 17.79139 SE: lon: -64.72022 lat: 17.75467 SW: lon: -64.77546 lat: 17.73921 NW: lon: -64.78095 lat: 17.77758 Mosaicked images were originally photographed at 1:30,000 or 1:20,000, and scanned from diapositives at a resolution of 25 microns, with pixel size of 0.5 x 0.5 m. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Fixed ground control points were selected through examination of imagery, and located in the field. GPS data was collected at each point, and approximately 10-15 points were utilized to orthorectify the imagery. Several additional points were subsequently used to calculate horizontal accuracy: Residuals in meters (root mean square error): 1971 x: 1.90 y: 1.38 1977 x: 1.83 y: 1.86 Pixel size: 0.5 x 0.5 m Lineage: Source_Information: Source_Citation: Citation_Information: Originator: National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), National Geodetic Survey (NGS) Publication_Date: 2005 Title: NGS Color Aerial Photography Geospatial_Data_Presentation_Form: remote-sensing image Publication_Information: Publication_Place: Silver Spring Publisher: MD Other_Citation_Details: These photographs were mosaiced and georeferenced by NOAA's National Ocean Service (NOS), National Centers for Coastal Ocean Science (NCCOS), Center for Coastal Monitoring and Assessment (CCMA), Biogeography Program Type_of_Source_Media: aerial photography and scanned photographs Source_Time_Period_of_Content: Time_Period_Information: Multiple_Dates/Times: Single_Date/Time: Calendar_Date: 19711120 Single_Date/Time: Calendar_Date: 19771207 Source_Currentness_Reference: ground condition Source_Citation_Abbreviation: NGS aerial photos Source_Contribution: Benthic features were interpreted and mapped from NGS aerial photos of the Salt River Bay region of aerial photographs of St. Croix, U.S.V.I. Process_Step: Process_Description: Ground control points, camera calibration data, and USGS DTM data were used to orthorectify 1200 dpi scans of the aerial photos using PCI Geomatica OrthoEngine version 9.1.2. Scanned photos were loaded into OrthoEngine with survey-grade GPS data, camera calibration factors, DTM data, and other corrective measures to eliminate spatial distortion. Once a satisfactory spatial model had been produced (RMS less than 1) the optimal sections of each photo were selected to minimize sun glint, turbidity, etc. and maximize area of interpretable bottom features.
