C’est toujours Longitude/Latitude l’ordre : X puis Y.
Ceux qui ne respectent pas cet ordre sont des incompétents :)
Et pour moins de troll, voici la spec http://geojson.org/geojson-spec.html#appendix-a-geometry-examples
Point coordinates are in x, y order (easting, northing for projected coordinates, longitude, latitude for geographic coordinates)

Mouais ... bon, ok, c'est pas faux.
Mais Leaflet n'est pas de cet avis : http://leafletjs.com/reference.html#latlng
Les specs, c'est moins important que l'utilisation réelle sur le terrain par des vrais gens, n'est-ce pas ?

Il y a eu un gros fail de certaines libs de carto (google y a malheureusement contribué) à considérer qu’elle ne représenteraient que des coordonnées sphériques, et jamais de coordonées projetées… Ce qui leur a permis de prendre des libertées avec les conventions des maths.
Même Hergé n’avait pas commis une boulette aussi énorme http://geantropie.free.fr/tintin/licorne61.jpg
Ne pas respecter la spec, ferait que tu casserait d’autres fonctions de leaflet, genre à tout hasard http://leafletjs.com/reference.html#geojson.
Le très vénérable ancêtre Openlayer a eu le bon gout de s’abstraire et demander explicitement x,y pour éviter la connerie qu’à faite leaflet http://dev.openlayers.org/releases/OpenLayers-2.13.1/doc/apidocs/files/OpenLayers/Geometry/Point-js.html#OpenLayers.Geometry.Point.OpenLayers.Geometry.Point
