gives the geodesic distance between latitude-longitude positions on the Earth.
gives the distance between locations specified by position objects or geographical entities.
gives the total distance from loc1 to locn through all the intermediate loci.
- GeoDistance[loc1,loc2] gives the distance between locations loc1 and loc2 as measured along the geodesic joining them on the surface of the reference ellipsoid. Heights are ignored.
- The result is returned as a Quantity object with dimensions of length. The unit used can be chosen with the option UnitSystem, which has $UnitSystem as default value.
- Latitudes and longitudes can be given as numbers in degrees, as DMS strings, or as Quantity angles.
- Position objects in GeoDistance[loc1,loc2] can be given as GeoPosition, GeoPositionXYZ, GeoPositionENU, or GeoGridPosition objects.
- In GeoDistance[loc1,loc2], the loci can be Entity objects with domains such as "City", "Country", and "AdministrativeDivision".
- For entities corresponding to extended geographic regions, GeoDistance by default computes the minimum distance between any points in the regions.
- GeoDistance[loc1,loc2] by default uses the reference ellipsoid associated with the datum for loc1.
- GeoDistance and GeoDirection solve the geodetic inverse problem.
- GeoDistance has option DistanceFunction, with the following settings:
"Boundary" minimum distance between any points in regions "Center" distance between centers of regions "SignedBoundary" distance to boundary, negative for interior points
- GeoDistance by default uses the setting DistanceFunction->"Boundary".
