Vector Map (VMap) Level 0 is an updated and improved version of the National Imagery and Mapping Agency's (NIMA) Digital Chart of the World (DCW®) and is produced by NGA.

The VMap Level 0 database provides worldwide coverage of vector-based geospatial data which can be viewed at 1:1,000,000 scale. It consists of geographic, attribute, and textual data. 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. The complete database is organized into 10 thematic layers.

The top level thematic layers are:

• Boundaries
• Elevation
• Hydrography
• Industry
• Physiography
• Population
• Transportation
• Utilities
• Vegetation

There are various layers underneath each top level category.

As VMAP0 is not suitable for scales more detailed than 1:1,000,000; VMAP0 is not suitable for precise locational work, however it is an excellent regional or global resource.
