ee.FeatureCollection

Les FeatureCollections peuvent être construites à partir des arguments suivants :

  - Une chaîne : supposée être le nom d'une collection.

  - Une seule géométrie.

  - Une seule fonctionnalité.

  - Une liste de fonctionnalités.

  - Une FeatureCollection GeoJSON

  - Un objet calculé : réinterprété comme une collection.

Utilisation	Renvoie
ee.FeatureCollection(args, column)	FeatureCollection

Argument	Type	Détails
args	ComputedObject|Feature|FeatureCollection|Geometry|List<Object>|Number|String	Arguments du constructeur.
column	Chaîne, facultative	Nom de la colonne de géométrie à utiliser. Utile uniquement lorsque vous travaillez avec une collection nommée.
