# Class GeoTIFFTagSet

java.lang.Object
javax.imageio.plugins.tiff.TIFFTagSet
javax.imageio.plugins.tiff.GeoTIFFTagSet

public final class GeoTIFFTagSet extends TIFFTagSet
A class representing the tags found in a GeoTIFF IFD. GeoTIFF is a standard for annotating georeferenced or geocoded raster imagery. This class does not handle the GeoKeys referenced from a GeoKeyDirectoryTag as those are not TIFF tags per se.

The definitions of the data types referenced by the field definitions may be found in the `TIFFTag` class.
