                                                Title:  VMAP_1V10 - Vector Map Level 0 (Digital Chart of the World)

Purpose:  The VMap Level 0 is a general purpose global database designed to

support Geographic Information Systems applications. 

                  Abstract:  The Vector Map (VMap) Level 0 database represents the third

edition of the Digital Chart of the World.  VMap Level 0 is a comprehensive 1:1,000,000 scale vector of the world. It consists of cartographic, attribute, and textual data stored on compact disc read only memory (CD-ROM). The primary source for the database is the National Imagery and Mapping Agency's (NIMA) Operational Navigation Chart (ONC) series. This is the largest scale unclassified map series in existence that provides consistent, continuous global coverage of essential basemap features.  The data includes major road and rail networks, major hydrologic drainage systems, major utility networks (cross-country pipelines and communication lines), all major airports, elevation contours (1000 foot(ft), with 500ft and 250ft supplemental contours), coastlines, international boundaries and populated places.
