Digital Chart of the World



    The Digital Chart of the World is a 1.7 GB digital geographic
database that is available on CD-ROM.  Like most US government
data it is public domain, price about US$200!

 More than 200 different types of attributes present worldwide
are logically organized into 17 thematic layers.  Since each
thematic layer may contain information in the form of points,
lines, and/or polygons, there are up to 27 possible coverages
present.  In addition to the attribute information most layers
contain one or more levels of annotation.  Most of the annotation
contains place name information for cities, mountains, lakes, or
other geographic features.  Other types of annotation supplement
attribute coding or contain data quality information.  The
original text size and location information are retained, thus
allowing the production of publication quality maps.  The major
thematic layers in the DCW database include international
boundaries, hydrography, elevation, populated places, roads,
railroads, utility lines, airports, cultural landmarks,
physiography, supplemental data, and data quality.

The BROWSE database is for worldwide maps:
