uk.ac.rdg.resc.edal.util.CoastlineReader

public class CoastlineReader
extends Object

A class with static methods to read data from the GSHHS binary format to create masks of land data. Also contains a method to apply such a mask to an image file. All data assumed to be in EPSG:4326. Its original purpose was to mask out oceans from satellite images for the MyOcean project. This doesn't fit nicely into EDAL yet, but it has some useful methods so it is going in the codebase. We may want to modify this for other purposes in the future.
