VMAP
Vector World Map: VMAP level 0 or Vector World Map formerly
known as Digital Chart of the World-DCW is improved
and updated from the National Imagery and Mapping
Agency's (NIMA) which is supported by our 3D GIS mapping software Global
Mapper.
The VMAP Level 0 database consisting of textual,
attribute, and geographic data allows viewing vector-based geospatial data
of worldwide coverage based on 1:1,000,000 scale Operational
Navigation Chart (ONC) series.
Military mapping authorities of the United States, Canada,
United Kingdom and Australia co-produced more than
1,800 megabytes of vector data organized into
10 thematic layers that's available on
four CD-ROM's.
The Vector World Map or DCW geographic area coverage
is divided into four libraries:
- North America
- Europe and North Asia
- South America, Africa, and Antarctica
- South Asia and Australia
VMAP Level 0 database includes:
- major road and rail networks
- major airports
- utility networks
- hydrologic drainage systems
- elevation contours
- coastlines
- international boundaries
- populated places
- geographic names index
VMAP Level 0 is accessible directly from the CD-ROM or
transferred to your computer systems hard drive and widely utilized in many professional
geographic information system (GIS) applications such as our Global Mapper.
To load a VPF database, in Global
Mapper v6.00 and above, either select the dht file at the root of
the VPF database tree or select the lht file
at a lower level to load just one coverage
from the database (the latter option is
usually useful for DNC
Charts).
