Graphic data were scanned, vectorized, and converted into the DXF file transfer format by means of an off—the—shelf PC—based system
consisting of a Datacopy model 612F scanner, CAD/camera vectorizer (by Autodesk) , and autoCAD software used on an IBM-AT. The data
were than loaded onto a Prime 9955 minicomputer where the ARC/INFO geoprocessing software was used to convert the files into
coverages, This publication oulines the entire procedure used from scanning the initial document to editing the final product, It also includes the FORTFRAN 77 and CPL programs used on the Prime computer that automated much of the processing.
