Vector Map (VMap) Level 0 is an updated and improved version of the National Geospatial-Intelligence Agency's (NGA - formerly NIMA) Digital Chart of the World (DCW).
The VMap Level 0 database provides worldwide coverage of vector-based geospatial data. It consists of geographic, attribute, and textual data stored on four CD-ROM's containing more than 1,800 megabytes of vector data organized into 10 thematic layers. The primary source for the database is the 1:1,000,000 scale Operational Navigation Chart (ONC) series co-produced by the military mapping authorities of Australia, Canada, United Kingdom, and the United States. VMap Level 0 includes major road and rail networks, hydrologic drainage systems, utility networks (cross-country pipelines and communication lines), major airports, elevation contours, coastlines, international boundaries and populated places. VMap Level 0 includes an index of geographic names to aid in locating areas of interest. Further information can be found on the NGA website.
Application software, called VPFVIEW V2.1 (developed by NIMA), allows users the ability to access and view VMap Level 0 data. This software, provided on a separate CD-ROM, has been developed to operate on an IBM PC (or compatible), as well as SUN UNIX, Silicon Graphics, Hewlett-Packard, and Macintosh environments.
