Coastlines
These examples show how to use the multi-resolution coastline
database, RANGS (Regionally Accessible Nested Global Shorelines),
developed by Rainer Feistel from Wessel and Smith's GSHHS (Global
Self-consistent Hierarchical High-resolution Shoreline) database. You
need to download and install it first; click here for more
information.
coast_1.ncl:
Demonstrates the three levels of coastline data in NCL.
To change the coastline to the medium level, set mpDataBaseVersion = "MediumRes".
The third example is of the multi-resolution coastline database. Once you have the RANGS database installed, set mpDataBaseVersion = "HighRes" to create maps using this database. Note: you should not use this database to plot maximal area plots, because 1) you will get horizontal lines through your plot, and 2) it takes a long time.
