Abstract: The Vector Map (VMap) Level 0 database represents the 5th ed. of the Digital Chart of the World. VMap Level 0 (VMap0) is a comprehensive 1:1, 000,000 scale vector basemap of the world. It consists of cartographic, attribute, and textual data stored on compact disc read only memory (CDROM). The data include major road and rail networks, major hydrologic drainage systems, major utility networks (cross-country pipelines and communication lines), all major airports, elevation contours (metric equivalent of 1000 foot (ft), with 500ft and 250ft supplemental contours), coastlines, international and first order boundaries and populated places.
