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

This dataset is a collection of GeoTIFF and MrSID format natural color orthophotos covering Nassau County, Florida. 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. Imagery was acquired for Nassau County at 0.9 foot ground sample distance (GSD) resolution. Flight height maintained during mission was 9,000 feet AGL. The imagery was captured at 12-bit radiometric resolution and converted to 8-bit radiometric resolution during post processing. The imagery was captured with 60% forwardlap and 30% sidelap between all adjacent flight lines. The imagery was obtained and processed by all digital means beginning with data acquisition using a Z/I Imaging Digital Mapping Camera (DMC), serial number DMC01-0046. The orthophotos are available in GeoTIFF and MrSID form. The projected coordinate system is State Plane Florida East (FIPS Zone 901), NAD 83 HPGN, GRS 80, Units Feet.
