Coastline Data

US Geological Survey format for world coastlines

The screen image shows part of a typical coastline data file. They are lists of longitude/latitude coordinates forming coastline segments, with different segments separated by a "nan nan" line.

Coastline Data files can be obtained free for any part of the world from USGS Coastline Extractor. Use the "Matlab" format for the files.
