Examples with GeocentricTranslationTest org.apache.sis.internal.referencing.provider.GeocentricTranslationTest used on opensource projects

Example 1 with GeocentricTranslationTest

use of org.apache.sis.internal.referencing.provider.GeocentricTranslationTest in project sis by apache.

the class EllipsoidToCentricTransformTest method testConcatenate.

/**
 * Tests {@link EllipsoidToCentricTransform#tryConcatenate(boolean, MathTransform, MathTransformFactory)}.
 * The test creates <cite>"Geographic 3D to 2D conversion"</cite>, <cite>"Geographic/Geocentric conversions"</cite>
 * and <cite>"Geocentric translation"</cite> transforms, then concatenate them.
 *
 * <p>Because this test involves a lot of steps, this is more an integration test than a unit test:
 * a failure here may not be easy to debug.</p>
