At the moment the Distance Calculation and Static Distance Calulation are using the using the ‘haversine’ formula [1]. But the result can be improved: Issue: Calc distance between Karlsruhe and New York: StreamPipes: 6230.166 km reference PostGIS: 6246.970 km \--\> Difference of ~17 km or 0,26 % error Calc distance between Karlsruhe and Rastatt: StreamPipes: 21.87866 km reference PostGIS: 21.908 km \--\> Difference of ~0,029 km or 0,13 % error Solution: Using GeographicLib as Library under MIT Licende [3][4] Using Geodesy Algorithm resolving different problems mentions in this paper [5] [1] https://www.movable-type.co.uk/scripts/latlong.html [3] https://mvnrepository.com/artifact/net.sf.geographiclib/GeographicLib-Java/1.50 [4] https://geographiclib.sourceforge.io/html/java/ [5] https://link.springer.com/article/10.1007/s00190-012-0578-z Imported from Jira [STREAMPIPES-131](https://issues.apache.org/jira/browse/STREAMPIPES-131).
