DCW-GMT for Debian
-------------------

The gmt-dcw Debian package includes the DCW-GMT basemap of the world in
NetCDF 4 format for use with GMT 5.

The DCW-GMT homepage [1] describes the project and the origin of the data as
follows:

"
 The Digital Chart of the World (DCW) is a comprehensive 1:1,000,000 scale
 vector basemap of the world. The charts were designed to meet the needs of
 pilots and air crews in medium-and low-altitude en route navigation and to
 support military operational planning, intelligence briefings, and other
 needs. For basic background information about DCW, see the Wikipedia entry
 (http://en.wikipedia.org/wiki/Digital_Chart_of_the_World).

 DCW-GMT is an enhancement to DCW in a few ways: (1) it contains more state
 boundaries (the largest 8 countries are now represented), and (2) the data
 have been reformatted to save space and are distributed as a single deflated
 netCDF-4 file. The raw files used to build dcw-gmt.nc came from the
 Princeton University Digital Map and Geospatial Information Center,
 accessible via website http://www.princeton.edu/~geolib/gis/dcw.html;
 however, the DCW access seems to have disappeared. Other sites with DCW data
 include the GeoCommunity at http://data.geocomm.com/readme/dcw/dcw.html.
