@Test public void testGetNextEquivalentLongitude() { assertEquals(0, GISUtils.getNextEquivalentLongitude(0, 0), 1e-8); assertEquals(180, GISUtils.getNextEquivalentLongitude(0, -180), 1e-8); assertEquals(360, GISUtils.getNextEquivalentLongitude(360, 0), 1e-8); assertEquals(361, GISUtils.getNextEquivalentLongitude(360, 1), 1e-8); assertEquals(360, GISUtils.getNextEquivalentLongitude(360, 360), 1e-8); assertEquals(719, GISUtils.getNextEquivalentLongitude(360, 359), 1e-8); }
