Constructor Detail GeocentricTransformTest public GeocentricTransformTest(String name)(Code) Constructs a test case with the given name. Method Detail main public static void main(String args)(Code) Runs the tests with the textual test runner. suite public static Test suite()(Code) Returns the test suite. testEllipsoid public void testEllipsoid() throws FactoryException(Code) Tests the orthodromic distance computed by DefaultEllipsoid . There is actually two algorithms used: one for the ellipsoidal model, and a simpler one for spherical model. We test the ellipsoidal model using know values of nautical mile at different latitude. Then, we test the spherical model with random values. If JDK 1.4 assertion is enabled, the spherical model will compare its result with the ellipsoidal one. Note about nautical mile: "Le mille marin était, en principe, la longueur de la minute sexagésimale du méridien à la latitude de 45°. Cette longueur dépendait donc des valeurs adoptées pour le rayon équatorial de la terre et son aplatissement. En France, le décret du 3 mai 1961 sur les unités de mesure, fixe à 1852 mètres la longueur du mille marin qui est également la valeur adoptée pour le mille marin international."
