                                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.
