Title: 1988 Mosaic of Aerial Photography of the Salt River Bay National Historical Park and Ecological Preserve
Short Name: sari_1988_orthophoto_met
Status: Completed
Publication Date: 2004
Abstract:

Aerial photographs taken by NOAA's National Geodetic Survey during 1988 were mosaicked and orthorectified by the Biogeography Branch. 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 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 0.5 - 4.0 km.

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.

Data Quality

Horizontal Positional Accuracy:

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):x: 1.09, y: 1.21 Pixel size: 0.5 x 0.5 m

Completeness Measure:

Cloud Cover: 0

Completeness Report:

Mosaicked images were originally photographed at 1:20,000, and scanned from diapositives at a resolution of 25 microns, with pixel size of 0.5 x 0.5 m. Images that covered the desired spatial extent (study area), and that minimized water glare and cloud cover were selected for orthorectification, and mosaicked. Extent of mosaic extends beyond the boundaries of the study area approximately 0.5 km - 4 km.

Conceptual Consistency:

These data are believed to be logically consistent, although not tested. Geometry appears topologically clean.

Process Steps

Process Step 1

CC ID: 601366
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.
