Distance between two positions on the reference ellipsoid:

Distance between two cities:

Distance between two fully specified geodetic positions:

Distance between two historical entities at the time of their closest approach:

Distances from a location to a list of different locations:

Total distance between several locations:

Compute the distances from your location to all US state capital cities:

Find the minimum, maximum and mean distances:

Plot a histogram of all those distances:

Draw a Mercator map of all geodesics from your location to the US capital cities:

A nautical mile was traditionally defined as the distance corresponding to a minute of arc of a meridian:

This depends on the latitude:

The standard "NauticalMiles" unit approximates the value at latitude 45 degrees:

GeoDistance is a symmetric function:

GeoDistance is a partial inverse of GeoDestination:

GeoDistance returns part of the result returned by GeoDisplacement for point-like locations:

The length of a degree of parallel strongly depends on latitude:

But the length of a degree of meridian is approximately constant:

The distance corresponding to a given meridian angle α increases when approaching the poles:

Compute distances between consecutive pairs in a list of points with GeoDistanceList:

The same result can be obtained using Partition and GeoDistance, though in a less efficient way:

Include the distance between the last and first point:

GeoDistance computes distances between points:

GeoLength computes the length of a geo path:

Construct points on a geodesic circle, starting with regular bearings:

On an ellipsoid, they are not exactly equidistant:

Construct multiple points along a geodesic, at regular distance intervals:

The list of distances can also be obtained with GeoDistanceList:

The distance between two locations coincides with the distance between their antipodal locations:

Distance between extended geo entities is computed between boundaries by default, and hence zero for contiguous entities:

Therefore, this total distance is also zero:

The GeoDistance of two historical entities that do not coexist in time returns unevaluated:
