Abstract : An accelerating interest in automatic name placement has revealed a growing need for the creation of cartographic data bases. An effort has been made to creat such a data base from two extent types of digitized USGS maps data. Features are defined by geographic data stored as graphic elements in the USGS 1:2,000,000 Digital Line Graph data files. These features are then used as a set onto which names extracted from the Geographic Names Information System data files are mapped. This mapping serves as a cartographic data base, supplying both a label and a graphic description of specific geographic features. Automatic generation of this data base draws nearer the realization of automated map generation.
