MS Gulf Coast 1 foot Aerial Photography
August 30, 2005
This photography was taken by Gulf Coast Area Mapping Company, Inc. for the MS Department of Transportation on August 30, 2005 in response to Hurricane Katrina.
The aerial photography was done from an altitude of 12,000 feet using a Leicha RC-30 aerial mapping camera. This camera is equipped with image motion compensation, gyro stabilized mount, and GPS control. The AWAR of the lense is 112 and the camera was last calibrated in September, 2004.
The film was Agfa Pan-80 high resolution black & white film. The images were scanned at 2000 dpi for 1’ pixel resolution using a Vexel Ultra Scan 5000 photogrammetric accuracy scanner.
Control for the images came a combination of points from the latest digital quarter quads and an analytical triangulation solution. The final images have been ortho corrected and are within about 5’ to 9’ of the actual geographic coordinates.
The data is stored in NAD83 State Plane MS East feet (2301) in MrSID format (30:1 compression). Average size per image – 6MB.
