Basic Examples  (5)

Extract the longitude from a geodetic position:

Compute the longitude of a position given in projected coordinates:

Longitude of Madrid:

Compute the longitude of a geo entity class:

Scope  (10)

Find your current longitude:

This is equivalent to the following:

Extract the longitude of a GeoPosition object:

Compute the longitude of any type of geo location:

Get the longitude of a geo entity:

This is equivalent to the following:

Extract the longitudes of the locations in a GeoPosition array:

Get the longitudes of the elements of a geo entity class:

That is equivalent to the following:

Extract the longitude of a geo location in a given datum:

Longitude automatically threads over lists of locations:

Extract Exif location information from an image:

Named locations:

These are the current longitudes of the magnetic poles, as determined by GeomagneticModelData:

Properties & Relations  (2)

Take a GeoPosition object:

Longitude returns the longitude of that location as a Quantity object:

The "Longitude" property of GeoPosition objects returns a numeric result in degrees:

The presence of elevation or temporal data does not affect the value of longitude:

Possible Issues  (1)

Longitude values can be given in any determination, not necessarily between and degrees:
