GeoDirection
GeoDirection[{lat1, long1}, {lat2, long2}]
gives the azimuthal direction from one latitude-longitude position on the Earth to another.
GeoDirection[pos1, pos2]
gives the azimuthal direction between positions specified by position objects.
Details and Options
- Latitudes, longitudes, and directions are given in degrees.
- GeoDirection["latlong1", "latlong2"] gives the direction between positions specified by latitudes and longitudes given as strings.
- Position objects in GeoDirection[pos1, pos2] can be given as GeoPosition, GeoPositionXYZ, GeoPositionENU, or GeoGridPosition objects.
- GeoDirection gives the angle in degrees relative to due north to get from one position to the other, when projected onto a reference ellipsoid. Heights are ignored.
- GeoDirection[pos1, pos2] by default uses the reference ellipsoid associated with the datum for
. - GeoDirection and GeoDistance solve the geodetic inverse problem.
- The algorithm used by GeoDirection can be specified by setting the Method option to one of the following values:
, 
, or 
.
