AERIAL CAMERA RESEARCH-AN ACCURACY COMPARISON USING THE ZEISS RMK 15/23 AND THE JENA LMK AERIAL CAMERAS

The Florida Department of Transportation has, for comparative purposes, obtained simultaneous photography from a single aircraft using both the JENA LMK and the ZEISS RMK 15/23 aerial cameras. Black and white nine inch mapping films utilized in both cameras were Kodak Panatomic X (2412), Plus X (2402) and Double X (2405). The test site utilized for this test was the Interstate 10 - U.S. 19 Interchange in Jefferson County, Florida. Flight elevations for black and white photography, above average terrain, were 1,200 feet, 2,400 feet, 3,000 feet and 4,800 feet - yielding photo scales of 1" = 200', 1" = 400', 1" = 500', and 1" = 800' respectively. Color infrared flights were made at 6,000 feet and 12,000 feet along a separate flight line in Leon and Jefferson Counties, and an additional flight line along the Wacissa River in Jefferson County, Florida. Kern PG 2 stereoplotter equipment was utilized to digitize cross sections of the test site. Two operators were utilized to read the models independently at each elevation for each type film for each camera over the twenty-six one hundred foot station test site. While some minor differences in area and volume were noted, the test results show that both the ZEISS RMK 15/23 and the JENA LMK yield acceptable results. A visual evaluation of the color infrared photography from the JENA LMK showed no noticeable "fall-off" in color, contrast and texture in any of the frames. (Author)
