AN EVALUATION OF COLOR AERIAL PHOTOGRAPHY FOR ENGINEERING PURPOSES

THIS REPORT INVESTIGATED WHETHER COLOR AERIAL PHOTOGRAPHY PROVIDED ADDITIONAL INFORMATION OR FACILITATED INTERPRETATION IN HIGHWAY CONSTRUCTION MATERIAL SURVEYS ABOVE AND BEYOND THAT PROVIDED BY CONVENTIONAL BLACK AND WHITE AERIAL PHOTOGRAPHY. BLACK AND WHITE PHOTOGRAPHY /MATTE AND GLOSSY PRINTS/, COLOR POSITIVE TRANSPARENCIES OBTAINED FROM KODAK EKTACHROME FILM, AND COLOR AND BLACK AND WHITE PRINTS OBTAINED FROM AGFACOLOR NEGATIVE FILM WERE EVALUATED. THE PHOTOGRAPHY, AT A SCALE OF 1'12,000, WAS ANALYZED AND THE MATERIALS INFORMATION THAT WAS OBTAINED WAS LATER COMPARED WITH DATA OBTAINED THROUGH FIELD CHECKING AND DRILLING. COLOR AERIAL PHOTOGRAPHY WAS FOUND TO BE USEFUL ONLY IN AREAS OF ERRATIC GROUND CONDITIONS WHERE GROUND INFORMATION COULD NOT BE USED EFFECTIVELY, AND WHERE THE COLOR IMAGE OR A CHANGE IN THE IMAGE COLOR COULD BE ASSOCIATED WITH A DESIRABLE TYPE OF MATERIAL. THE REPORT ALSO CONTAINED THE RESULTS OF A NON-HPR STUDY WHICH EVALUATED THE SAME TYPES OF PHOTOGRAPHY AT A SCALE OF 1'12,000 IN DETERMINING ITS USEFULNESS IN DETECTING HIGHWAY PAVEMENT STRAINS WHICH, IN KANSAS, ARE ASSOCIATED WITH CRACKS AND SUBSEQUENT DISINTEGRATION. THE COLOR PHOTOGRAPHY WAS REPORTED TO HAVE A DISTINCT BUT LIMITED USE. /BPR/
