[Geotools-gt2-users] NaN when calculating distances with GeodeticCalculator

[Paul S. <Pau...@to...>]

Hi everybody,


I got a NaN back when calculating the distance between two latlons that are very close together. Is this the intended behavior of the GeodeticCalculator? The following shows an example in Scala:

val gc: GeodeticCalculator = new GeodeticCalculator(DefaultEllipsoid.WGS84)

gc.setStartingGeographicPoint(-73.99102, 40.85273)

gc.setDestinationGeographicPoint(-73.99102287448099, 40.852729999999994)

gc.getOrthodromicDistance


Intuitively, I would expect a small number or 0 as a return value. Do I have to care in my code about NaNs?

I used geotools version 18.2 if this helps.


Best regards, Paul
