nixpkgs / dcw-gmt - DCW-GMT is an enhancement to the original 1:1,000,000 scale vector basemap of the world, available from the Princeton University Digital Map and Geospatial Information Center. It contains more state boundaries (the largest 8 countries are now represented) than the original data source. Information about DCW can be found on Wikipedia (https://en.wikipedia.org/wiki/Digital_Chart_of_the_World). This data is for use by GMT, the Generic Mapping Tools.
