USE OF AERIAL SURVEYS IN CONNECTICUT

AERIAL PHOTOGRAPHY FOR HIGHWAY ENGINEERING PURPOSES WAS FIRST USED BY THE CONNECTICUT STATE HIGHWAY DEPARTMENT IN 1930 FOR LOCATING AND DEVELOPING SCHEMATICS, AND PREPARING PRELIMINARY RIGHT-OF-WAY ACQUISITION MAPS FOR THE MERRITT PARKWAY. IN 1944, THE FIRST TOPOGRAPHIC MAPS COMPILED BY PHOTOGRAMMETRIC METHODS WERE USED BY THE HIGHWAY DEPARTMENT. SINCE THEN THE HIGHWAY DEAPRTMENT HAS OBTAINED OVER 800 LINEAL MILES OF TOPOGRAPHIC MAPPING. AS THE DEPARTMENT HAS NO ESTABLISHED PHOTOGRAMMETRIC SECTION, ITS AERIAL PHOTOGRAPHY AND PHOTOGRAMMETRIC WORK ARE ACCOMPLISHED UNDER NEGOTIATED CONTRACT BY ESTABLISHED PHOTOGRAMMETRIC FIRMS. PRELIMINARY SURVEY PLANNING AND THE EARLY DETERMINATION AND COMPARISON OF ALTERNATIVE HIGHWAY LOCATIONS ARE DONE BY USE OF THE STANDARD TOPOGRAPHIC MAPS PUBLISHED BY THE U.S. GEOLOGICAL SURVEY. THE USE OF PHOTOGRAMMETRY FOR TOPOGRAPHIC MAP COMPILATION IN CONNECTICUT IS DESCRIBED. THE HIGHWAY DEPARTMENT CONTEMPLATES GREATER USE OF TOPOGRAPHIC MAPS COMPILED AT THE SCALE OF 40 FEET TO ONE INCH IN THE FUTURE FOR HIGHWAY LOCATION, DESIGN, AND PREPARATION OF CONTRUCTION PLANS.
