Aerial Photography and Imagery, Ortho-Corrected - 2007 Digital Orthophotos - Highlands County

This dataset is a single orthophoto from a collection of GeoTIFF format natural color orthophotos covering the Southwest Florida Water Management District. 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 5,000 foot by 5,000 foot cell area on the ground. The source imagery was obtained in February and March of 2007 and used to produce orthophotos with a one foot ground sample distance (GSD). Imagery was acquired at 0.9 foot GSD resolution. Flight height maintained during mission was 8,650 feet AGL. The imagery was captured at 12-bit radiometric resolution and converted to 8-bit radiometric resolution during post processing. The imagery was captured with 25% sidelap between all adjacent flight lines. The SWFWMD project area was divided into 5 flight blocks due to neccessary base station and flight line length requirements. The imagery was obtained and processed by all digital means beginning with data acquisition using an ADS40 digital sensor. The orthophotos are available in GeoTIFF form. The projected coordinate system is State Plane Florida West (Zone 902), NAD 83 HARN, GRS 80, Units Feet.
