# Returned landmark information

The `ReturnValue` property returned by a synchronous `GetList` call and by `callback` for an asynchronous `GetList` call is an iterator containing the requested landmark information. Each item (object) in the iterator corresponds to one landmark, landmark category, or landmark database, depending on what type of landmark information was requested. The following sections describe the object properties returned for each type:

- Landmark

- Landmark category

- Landmark database
