GeoDistance

GeoDistance[{lat1, lon1}, {lat2, lon2}] gives the geodesic distance between latitude-longitude positions on the Earth.

• GeoDistance[loc1, loc2] gives the distance between locations specified by position objects or geographical entities.
• GeoDistance[{loc1, …, locn}] gives the total distance from loc1 to locn through all the intermediate loci.

Examples

GeoDistance[{40.7, -74.0}, {51.5, -0.1}]

GeoDistance[Entity["City", {"NewYork", "NewYork", "UnitedStates"}], 
  Entity["City", {"London", "GreaterLondon", "UnitedKingdom"}]]
