– Fonction permettant de convertir des coordonnées exprimées dans le système décimal dans le système sexagésimalp.dms2dec(frame)
– Fonction permettant de convertir des coordonnées dans l'autre sens (du système sexagésimal dans le système décimal)p.latitude(frame)
– récupère la latitude de coordonnées (locale ou stockées sur Wikidata). Surtout utile pour les infoboîtesp.longitude(frame)
– récupère la longitude de coordonnées (locale ou stockées sur Wikidata). Surtout utile pour les infoboîtesp.distance(frame)
– calcule la distance entre deux points dont on précise les latitudes et longitudes.
p._coord(args)
– similaire à p.coord, mais à utiliser depuis un autre module Luap._dms2dec(dmsobject)

Exemples basiques
Il existe deux moyens pour renseigner dans un article des coordonnées
- À partir des coordonnées décimales
{{#Invoke:Coordinates | coord |43.651234|-79.383333}}
: Erreur Lua : callParserFunction: function "#coordinates" was not found- la latitude(43.651234) et la longitude (-79.383333) de Toronto sont renseignés sous formes décimale
- À partir des coordonnées sexagésimales
{{#Invoke:Coordinates | coord |43|29|4|N|79|23|0|W}}
: Erreur Lua : callParserFunction: function "#coordinates" was not found- la latitude(43/29/4/N) et la longitude (79/23/0/W) de Toronto sont renseignés sous forme d'un quadruplet Heure/Minute/Seconde/Sens représentant le calcul sous forme de minutes d'arc.
{{#Invoke:Coordinates | coord |43/29/4/N|79/23/0/W}}
: Erreur Lua : callParserFunction: function "#coordinates" was not found- la latitude(43/29/4/N) et la longitude (79/23/0/W) de Toronto sont renseignés directement
- À partir des coordonnées géographiques issu de Wikidata seulement pour les coordonnées principale d'un article
{{#Invoke:Coordinates | coord }}
Le format de sortie est par défaut le format d'entrée mais on peut le changer en passant un argument supplémentaire sous la forme |format=xxx
- dms pour un affichage degrée/minute/seconde
{{#Invoke:Coordinates | coord |43.651234|-79.383333|format=dms}}
: Erreur Lua : callParserFunction: function "#coordinates" was not found
- dms long pour un affichage degrée/minute/seconde avec l'orientation en toute lettres
{{#Invoke:Coordinates | coord |43.651234|-79.383333|format=dms long}}

Affichage dans la barre de titre
Il est possible de renseigner les coordonnées en haut de la page en précisant l'argument |display=
- {{#invoke:Coordinates|coord|43.65|-79.38|display=inline}} : Affiche uniquement les coordonnées dans le corps du texte
- C'est le comportement par défaut
- {{#invoke:Coordinates|coord|43.65|-79.38|display=title}} : Affiche uniquement les coordonnées dans la barre de titre
- {{#invoke:Coordinates|coord|43.65|-79.38|display=inline,title}} : Affiche les coordonnées dans le corps du texte et dans la barre de titre
Ce modèle « catégorise » la page qui l’emploie dans la catégorie article géolocalisé.
Pour un affichage différent entre les coordonnées dans le texte et celui dans le titre, on peut utiliser l'argument |formatitle
- {{#invoke:Coordinates|coord|43.65|-79.38|display=inline,title|format=dec|formatitle=dms}} : Affiche les coordonnées dans le corps du texte en décimal et dans la barre de titre au format sexagésimal
Gestion des erreurs
Si les paramètres sont mal renseignés ou incorrects, une balise est affiché à coté des coordonnées précisant le type d'erreur.
- Exemple d'appel erronés
- {{#invoke:Coordinates|coord|2843.65|-79.38}} : Erreur Lua : callParserFunction: function "#coordinates" was not found

dms2dec
Wrapper to allow templates to call dms2dec directly.
Usage:
{{#invoke:Coordinates | dms2dec | direction_flag | degrees |
minutes | seconds }}
Converts DMS values specified as degrees, minutes, seconds too decimal format.
direction_flag is one of N, S, E, W, and determines whether the output is
positive (i.e. N and E) or negative (i.e. S and W).

Refer to {{coord}} documentation page for many additional parameters and

Note: This function provides the visual display elements of {{coord}}. In
order to load coordinates into the database, the {{#coordinates:}} parser
function must also be called, this is done automatically in the Lua
