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. |
