24-bit True Color SE Quadrant of RINCON NE, Orthophoto Production for Puerto Rico and US Virgin Islands (rincon3_2004.tif)

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.
