The generation of a prototype USGS 1 : 24, 000-Scale topographic map from digital line graph data

Abstract

In an effort to modernize the production of graphic maps, the U.S. Geological Survey Is investigating the development of automated methods for the production of standard topographic maps using Digital Line. Graph (DLG) data. This paper describes the development of processes that led to the production of a fully symbolized color composite proof of the l:24,Q00-scale Bombay, New York – Quebec quadrangle from Digital Line Graph data archived In. the National Digital Cartographic Data Base. The project was developed to Include the use of existing hardware and software for production, to maximize the automation, of production procedures wherever possible; to minimize the use of interactive editing, to create symbols that meet established l:24,000-scale map series standards, and to produce publication-quality output.
