Low resolution coastlines for the Generic Mapping Tools

GSHHG is a high-resolution shoreline data set amalgamated from two databases: Global Self-consistent Hierarchical High-resolution Shorelines (GSHHS) and CIA World Data Bank II (WDBII). GSHHG contains vector descriptions at five different resolutions of land outlines, lakes, rivers, and political boundaries. This data is for use by GMT, the Generic Mapping Tools.

This package contains the crude, low and intermediate resolution coastlines which will be enough to get you started.

Use gmt-gshhg-high or gmt-gshhg-full to create better quality maps at an higher resolution, but be aware that the full maps take space on your disk.
