GSHHG (Global Self-consistent, Hierarchical, High-resolution Geography Database; formerly Global Self-consistent, Hierarchical, High-resolution Shoreline Database (GSHHS)) is a high-resolution shoreline data set amalgamated from two data bases (the CIA world database WDBII, and the World Vector Shoreline database) in the public domain. The data have undergone extensive processing and are free of internal inconsistencies such as erratic points and crossing segments. The shorelines are constructed entirely from hierarchically arranged closed polygons. The four-level hierarchy is as follows: seashore, lakes, islands within lakes, ponds within islands within lakes.
Semi-transparent orthographic projection, centered on 40° N, 40° W, using shoreline data from GSHHG ("crude level")
The data can be used to simplify data searches and data selections, or to study the statistical characteristics of shorelines and land-masses. It comes with access software and routines to facilitate decimation based on a standard line-reduction algorithm.
