EQUIPMENT, METHODS AND STANDARDS OF ACCURACY APPLIABLE TO AERIAL SURVEYS

THIS PAPER IS A DISCUSSION OF THE VARIOUS METHODS OF USING AERIAL SURVEYS AND MAPS COMPILED BY PHOTOGRAMMETRIC METHODS IN HIGHWAY ENGINEERING INVESTIGATIONS. SCALES OF PHOTOGRAPHS, MOSAICS, AND MAPS FOR DIFFERENT PURPOSES ARE DISCUSSED, ALONG WITH HORIZONTAL AND VERTICAL ACCURACY REQUIREMENTS. THE PAPER BRIEFLY REPORTS ON AN INVESTIGATIVE STUDY THAT IS BEING MADE FOR THE STATE HIGHWAY DEPARTMENT OF INDIANA TO DEVELOP DIRECTLY FROM LARGE-SCALE AERIAL PHOTOGRAPHS BRIDGE SITE TOPOGRAPHIC MAPS AT A SCALE OF 30 FT PER IN. EQUIPMENT CONSIDERATIONS ARE PRESENTED FOR A PROPOSED PHOTOGRAMMETRIC SYSTEM WHICH WILL INCLUDE AN AERIAL CAMERA, PROCESSING LABORATORY, AND PHOTOGRAMMETRIC PLOTTERS. /AUTHOR/
