COLOR PHOTOS FOR HIGHWAY ENGINEERING

RESULTS OF THE USE OF AERIAL COLOR TRANSPARENCIES AND PRINTS IN ENGINEERING MATERIALS SURVEYS BY THE FEDERAL HIGHWAY PROJECTS OFFICE, REGION 9, U. S. BUREAU OF PUBLIC ROADS, SHOWS THAT THEY HAVE MANY ADVANTAGES OVER BLACK AND WHITE PHOTOGRAPHS. A PHOTOGRAPHY SCALE OF 1:6,000 SEEMS TO PROVIDE OPTIMUM RESULTS FOR MATERIALS SURVEYS. PRELIMINARY INVESTIGATION OF INFRARED COLOR PHOTOGRAPHS SHOWS THAT ALTHOUGH IT DOES HAVE SOME ADVANTAGES OVER CONVENTIONAL COLOR PHOTOGRAPHS FOR ENGINEERING INTERPRETATION, IT CAN BE BEST EMPLOYED AS A SUPPLEMENT TO COLOR FILM. THE DEVELOPMENT OF THE STEREOIMAGE ALTERNATOR SYSTEM AND TECHNOLOGICAL ADVANCE MADE BY THE FILM INDUSTRY MADE IT POSSIBLE TO USE COLOR PHOTOGRAPHS FOR TOPOGRAPHIC MAPPING WITH DOUBLE PROJECTION ANAGLYPHIC PLOTTING INSTRUMENTS AS WELL AS FOR INTERPRETATION. /AUTHOR/
