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.
