s and crossing segments. The shorelines are constructed entirely from hierarchically arranged closed polygons.
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.
GSHHS is developed and maintained by Dr. Paul Wessel at the
University of Hawai'i , and Dr. Walter H. F. Smith at theNOAA Laboratory for Satellite Altimetry .See also
