MAPPING URBAN AMERICA WITH AUTOMATED CARTOGRAPHY

LATE IN 1972 THE GEOGRAPHY DIVISION OF THE BUREAU OF THE CENSUS WAS AUTHORIZED TO BEGIN DEVELOPING A SERIES OF URBAN ATLASES FOR THE NATION'S 125 LARGEST STANDARD METROPOLITAN STATISTICAL AREAS. THE ATLASES WERE TO BE A CONTINUATION OF THE BUREAU'S LONG HISTORY OF PRODUCING HIGH QUALITY STATISTICAL MAPS EVEN THOUGH THEY WERE TO BE PRODUCED BY A COMPUTER, WITHIN A YEAR, AND AT A COST OF APPROX. ONE-FIFTH THAT OF MANUAL CARTOGRAPHIC TECHNIQUES. THE PROJECT UTILIZED A LASER BEAM, LINE-FOLLOWING DIGITIZER; INTERACTIVE COMPUTER EDITING ON A CATHODE RAY TUBE; AND THE DIRECT PRODUCTION OF COLOR SEPARATION NEGATIVES ON MICROFILM FROM A COM UNIT. IN ALL THREE OF THESE AREAS THE "STATE OF THE ART" WAS ADVANCED IN ORDER TO SUCCESSFULLY COMPLETE THE PROJECT. THE PROJECT DEMONSTRATES THAT HIGH QUALITY MAPS CAN BE EFFICIENTLY PRODUCED FROM COMPUTER PREPARED MICROFILM AT A LOWER COST PER MAP THAN IS POSSIBLE WITH ANY OTHER APPROACH. /AUTHOR/
