The Development of Small Scale Map Control via Digital Paneling of Large Scale Map Source.

Abstract

A digital method has been devised which circumvents the traditional photomechanical reduction of large scale map source and the subsequent manual paneling of those reductions to a smaller scale control projection. The method requires the automatic digitization (via a scanner) of overlays which depict selected features compiled from the large scale source. The scanned data is vectorized. At a digital edit station, the data is then mathematically transformed to the desired compilation projection using common control points. Through file merging, the data sets are collected and input to a high-speed plotter where planimetric and hypsographic control bases are plotted for chart compilation. (Author)
