Paper Abstract

This paper presents operating details and performance specifications for an automatic laser raster scanner that provides an ordered vector (chain) file as an output. Several recent software enhancements to the system will be discussed. In the past, the vectorizing software ran as a post processor to the scanning system. The total systems software (scanner, vectorizer, control program) have now been integrated to provide a significant performance improvement. An entirely new software package will also be discussed. This single program utilizes the same hardware (scanner plus PDP 11/70) and produces the vector output "on the fly" but with performance improvements over the integrated system software. Speeds of over 5000 lineal inches/hour are possible. Quality of vector output and its relationship to DTM are an important topic. Slides of vector/raster output will be shown to illustrate the systems capabilities, and discussed in terms of the system hardware and software.
