DEVELOPMENT AND PRODUCTION OF TWO-COLOR AERIAL PHOTOMOSAIC CONTRACT PLANS

THE INCREASED COMPLEXITY OF HIGHWAY DESIGN AND CONSTRUCTION HAS PROMPTED THE USE OF AERIAL PHOTOGRAPHY AND TWO-COLOR PRINTING TO DEPICT PROPOSED DESIGNS MORE EASILY. A SOFT GREEN INK IS USED TO SHOW THE AERIAL PHOTOGRAPH BACKGROUND AND BLACK INK SHOWS THE PROPOSED DESIGNS. THE TECHNIQUE IS A DEPARTURE FROM TRADITIONAL DRAFTING METHODS IN THAT A BASE DRAWING IS USED FOR ONE COLOR (GREEN) AND AN OVERLAY DRAWING FOR THE OTHER COLOR (BLACK). THIS METHOD IS COMPATIBLE WITH THE MODERN "SCISSORS DRAFTING" OR "STICK-UP" TECHNIQUE NOW BEING USED BY MANY STATE HIGHWAY DEPARTMENTS. RESULTS HAVE SHOWN GREATER CLARITY AND INCREASED FLEXIBILITY IN THE USE OF AERIAL PHOTOGRAPHY AND BETTER RESULTS IN REPRODUCTIONS FROM BLACK-AND- WHITE MICROFILM. /AUTHOR/
