History
- 1991-1993: The National Imagery and Mapping Agency (NIMA) develops the Digital Chart of the World (DCW) for the US Defense Mapping Agency (DMA) with themes including Political/Ocean Populated Places, Railroads, Roads, Utilities, Drainage, Hypsography, Land Cover, Ocean Features, Physiography, Aeronautical, Cultural Landmarks, Transportation Structure and Vegetation. One of the sources for the data was the Operational Navigation Chart that compiles military mapping from Australia, Canada, United Kingdom, and the United States.
VMAP (level 0) is a slightly more detailed reiteration of the DCW.
VMAP (level 1) has much higher resolution data.
- 2004 The National Imagery and Mapping Agency (NIMA) is renamed to National Geospatial-Intelligence Agency which will include other mapping agencies such as the Defense Mapping Agency (DMA), the Central Imagery Office (CIO) and the Defense Dissemination Program Office (DDPO). All VMAP data will subsequently be distributed through the NGA.
