Class GreatCircleDistance

java.lang.Object
org.apache.jena.geosparql.implementation.great_circle.GreatCircleDistance
public class GreatCircleDistance extends Object
Great Circle distance uses Haversine formula. There are situations where the Vincenty formula is more accurate. However, the implemented Vincenty formula has errors, see Test 'testVincentyFormula_Distance8' and 'testVincentyFormula_Distance8'.
