ADOPTION OF AERIAL SURVEYING FOR HIGHWAYS

AERIAL SURVEYS HAVE PROVED OF PRACTICAL VALUE IN ALL STAGES OF HIGHWAY ENGINEERING. A BRIEF HISTORY IS GIVEN OF ADOPTING AERIAL SURVEYS AND THEIR MANY USES ARE EXPLAINED. IDENTIFICATION OF IMAGES ON THE AERIAL PHOTOGRAPHS, AND THEIR INTERPRETATION AND MEASUREMENT BY PHOTOGRAMMETRIC METHODS, AS NECESSARY, PROVIDE HIGHWAY ENGINEERS AND ALL COOPERATING AND INTERESTED OFFICIALS WITH INFORMATION AND DATA OF THE RIGHT KIND AND AMOUNT AS NEEDED. AERIAL PHOTOGRAPHS, ESPECIALLY WHEN EXAMINED STEREOSCOPICALLY, SHOW LANDFORM AND LAND USE, SOILS INFORMATION, AND INDICATE THE BEST PLACE FOR THE HIGHWAY AND ITS STRUCTURES AND WHETHER THE MORE VALUABLE LANDS CAN BE AVOIDED. FROM ONE TERMINAL POINT TO ANOTHER, AERIAL PHOTOGRAPHS OF SMALL SCALE PERMIT DETERMINATION OF THE FEASIBLE ROUTE BANDS BETWEEN INTERMEDIATE CONTROLS AND OBJECTIVES AND SELECTION OF THE BEST ROUTE, BASED ON COMPARATIVE VALUES OF DIRECTION, CURVATURE, GRADE, SERVICE TO TRAFFIC, AND OCCUPANTS OF ADJACENT LAND AND THE COSTS OF RIGHT-OF-WAY, CONSTRUCTION, AND MAINTENANCE. BY USE OF AERIAL PHOTOGRAPHS OF LARGE SCALE AND PHOTOGRAMMETRIC METHODS, THE PRELIMINARY SURVEY CAN BE MADE ON THE BEST ROUTE FOR DESIGN OF THE HIGHWAY LOCATION AND PREPARATION OF PRELIMINARY PLANS, WHEREVER GROUND COVER IS NOT UNUSUALLY DENSE, TALL, AND EXTENSIVE.
