High 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 high resolution coastlines which are required to create high quality maps with GMT.
