AERIAL SURVEYS AND USES OF PHOTOGRAMMETRY FOR HIGHWAYS

THE AERIAL SURVEYS BRANCH OF THE US BUREAU OF PUBLIC ROADS WAS ESTABLISHED FOLLOWING THE SUCCESSFUL COMPLETION OF A COMPREHENSIVE AERIAL SURVEY TO LOCATE FEASIBLE HIGHWAY ROUTES THROUGH A 90,000 SQUARE MILE AREA IN THE CENTRAL UNITED STATES. AERIAL SURVEYS FOR HIGHWAYS COMPRISE TAKING AND USING AERIAL PHOTOGRAPHS, REGARDLESS OF THEIR TYPE OR SCALE AND MANNER OF USE, WHILE ACCOMPLISHING THE ESSENTIAL PHOTOGRAPHIC INTERPRETATION (INCLUDING PHOTOGRAMMETRY AND ELECTRONIC COMPUTER APPLICATIONS) AND REQUISITE GROUND CONTROL SURVEYS. RECONNAISANCE SURVEYS FOR DETERMINING FEASIBLE ROUTES AND COMPARING THEM TO SELECT THE BEST ROUTE HAVE BEEN COMPLETED AND REPORTS PREPARED FOR HIGHWAY PROJECTS OF DIVERSIFIED TRAFFIC REQUIREMENTS AND VARIOUS CONSTRUCTION STANDARDS IN REGIONS OF AFRICA, HAWAII, AND CONTINENTAL UNITED STATES. IN ADDITION, ROUTE LOCATIONS FOR NUMEROUS HIGH-STANDARD SECTIONS OF THE INTERSTATE HIGHWAY SYSTEM HAVE BEEN DETERMINED. RECONNAISANCE SURVEY REPORTS ARE WRITTEN ACCORDING TO THE SPECIFIC REQUIREMENTS OF EACH SURVEY. PRELIMINARY SURVEY MAPPING IS USUALLY DONE ON A JOINT RESEARCH PROJECT BASIS. IN PRELIMINARY SURVEY MAPPING, NEW PHOTOGRAPHY IS DESIGNED AND TAKEN FOR EACH SURVEY PROJECT. WORK OF THE AERIAL SURVEYS BRANCH SELDOM CONTINUES BEYOND THE MAPPING PHASES OF THE PRELIMINARY SURVEY STAGE OF HIGHWAY ENGINEERING INTO THE DETAILED DESIGN PHASES. SPECIAL SERVICES ARE A CONTINUAL AND IMPORTANT FUNCTION OF THE BRANCH. NUMEROUS TRIPS HAVE BEEN MADE TO REGIONAL AND DIVISION OFFICES OF THE BUREAU TO PERFORM A CONSULTING ENGINEERING SERVICE, ESPECIALLY IN OBTAINING AERIAL SURVEY SERVICES BY CONTRACT FOR HIGHWAY ENGINEERING SURVEY AND DESIGN PURPOSES. AERIAL SURVEY TRAINING HAS BEEN GIVEN TO HIGHWAY ENGINEERS, ADMINISTRATIVE PERSONNEL, JUNIOR ENGINEERS, AND MATERIALS ENGINEERS SINCE 1947. DATA ON SURVEY COSTS RELATIVE TO ALL TYPES OF HIGHWAY SURVEYS ARE COMPILED AND REVISED ON A CONTINUOUS BASIS TO KEEP COST RECORDS CURRENT AND AVAILABLE TO ANSWER REQUESTS FOR INFORMATION.
