public class GARSGraticuleLayer
extends AbstractGraticuleLayer

Displays the geographic Global Area Reference System (GARS) graticule. The graticule has four levels. The first level displays lines of latitude and longitude. The second level displays 30 minute square grid cells. The third level displays 15 minute grid cells. The fourth and final level displays 5 minute grid cells. This graticule is intended to be used on 2D globes because it is so dense.
