This dataset is a single orthoimage from a collection of GeoTIFF format natural color orthoimages covering the islands of Puerto Rico, Mona, Desecheo, Culebra, Vieques, and the US Virgin Islands.
An orthophoto is remotely sensed image data in which displacement of features in the image caused by terrain relief and sensor orientation have been mathematically removed. Orthophotography combines the image characteristics of a photograph with the geometric qualities of a map. Each orthophoto provides imagery for a nominal 3.75 minute (in latitude and longitude) cell area. The source imagery was obtained in October 2004 and used to produce orthophotos with a one meter ground resolution. Imagery was acquired at 0.86 meter ground sample distance (GSD) resolution. Flight height maintained during mission was 27,000 feet AGL. The imagery was captured at 12-bit radiometric resolution and converted to 8-bit radiometric resolution during post processing. The imagery was obtained and processed by all digital means beginning with data acquisition using a Leica ADS40 Digital Airborne Sensor. The orthophotos are available in GeoTIFF form. The projected coordinate system is UTM zone 19 N, NAD 83, GRS 80, Units Meters.
The purpose of this project is to provide the United States Department of Agriculture's (USDA) Aerial Photography Field Office (APFO) with current true-color digital orthophotography for Puerto Rico, the U.S. Virgin Islands, and the surrounding islands. The APFO is the prime source of aerial imagery for USDA's research needs. The contracting agency for the project is the St. Louis District of the U.S. Army Corp of Engineers (USACE).
The data design specifications for this product includes several directed to insure its quality, consistency, and usability. These specifications address some of the technical issues associated with orthoimage production: 1) the tops of buildings and other structures elevated above the surface of the ground 'tilt' away from the center point of the source photography and from their own bases as a result of perspective and their height which is not compensated for in digital elevation models of the ground surface and 2) individual orthoimages may be assembled from several source images (strips).

Sample points taken from overlapping areas of adjacent image strips that contributed image chips to each orthophoto tile are typically consistent to the 2-3 pixel level. This not only ensures that a consistent mosaic can be created from the adjacent image strips acquired with the ADS40 pushbroom scanner but also means that the images have good precision and as a group are spatially self-consistent. Imagery was rectified to a recent LIDAR derived DEM. Aerotriangulation generates a RMSE for the positional accuracy of photo control for the final block adjustment to insure that the geo-reference accuracy of the imagery block is more than sufficient to support the specified orthorectification accuracy.
The data provided in this publication is a subset of coverage for the Rincon study area. Additional data is available for all of the islands of Puerto Rico, Culebra, Vieques, Mona, Desecheo, and the US Virgin Islands. Each orthophoto has an overedge of approximately 300 meters on all sides of its centering 3.75 minute cell.
These data are compiled to meet project specifications, which are that 90 percent of all well-defined points tested must fall within 10 meters.

Horizontal accuracy was checked using ground survey control collected contemporaneously with image acquisition. Ground survey consisted of photo identifiable points.

Image Acquisition for Orthophoto Production.
Ground control consisted of photo identifiable surveyed points. The imagery was collected at an altitude of 8229m using an ADS40 digital sensor. Image quality was verified during the post flight review phase. Factors considered during this review included but were not limited to the presence of smoke and/or cloud cover, contrails, light conditions and sun glint.
The triangulated strips were rectified with a current LIDAR DEM of the area. The red, green, and blue bands were combined to produce the orthophoto.
The ADS40 sensor collects twelve bit image data which requires radiometric adjustment for output in standard eight bit image channels. Converting to eight bit results in a reduction of the color range from 4096 to 256 - thus loss of radiometric detail is inevitable. The extra dynamic range of the sensor permits greater object differentiation in shadows and in bright areas. The sixteen bit dynamic range permitted the imagery to be more effectively color balanced than is possible with eight bit imagery. This was accomplished by performing tonal enhancements immediately prior to the reduction from sixteen bit to eight bit data. In addition to color balancing these eight bit images were adjusted to create seamless imagery to the highest extent practically achievable.
The imagery was mosaicked using a combination of automated and manual seamlines generation. Project specified tiles were extracted from the mosaic. Final image tiles were reviewed for artifacts and anomalies and adjusted as part of quality control procedures. Adjacent images are compared for consistency in overlap regions.

The metadata was edited to remove errors as well as update some information. Edits include updating the citation section with the DOI link and a slight modification to the dataset title, added the USGS Thesaurus, added keywords section with USGS persistent identifier as theme keyword, replaced distribution liability with FSP statement. Other unrequired blank fields were deleted, duplicate entries within a field were deleted, required empty elements were fixed with “information unavailable from original metadata”. The metadata date (20070223), but not the contact (except email and contact instructions) was updated. The metadata available from a harvester may supersede metadata available from the publication. Compare the metadata dates to determine which metadata file is most recent. The metadata available from a harvester may supersede metadata available from the publication.
