These templates calculate the distance between two geographic points using Vincenty's formulae.
Usage[edit]
{{User:Tcncv/Geodist | lat1 | long1 | lat2 | long2 }}
All parameters are signed decimal values in degrees.
Examples[edit]
- Lower 45 degrees latitude = 4984.944
- Upper 45 degrees latitude = 14986.91 (problem case)
- Upper 45 degrees latitude = 5017.021 (adjusted)
- 45 degrees longitude = 5009.321
- 45/45 lat/longitude = 6662.454
- Paris to Berlin - 878.593 km (Vincenty 878594.288 m)
- Los Angeles to Perth - 15023.658 km (Vincenty 15023747.718 m)
- London to Cape Town - 9635.44 km (Vincenty 9635442.275 m)
- Moscow to Washington DC - 7843.327 km (Vincenty 7843324.779 m)
- Rio to Tokyo - 18558.6 km (Vincenty 18558543.383 m)
