# ARFrame.WorldMappingStatus.mapped

World tracking has adequately mapped the visible area.

```
case mapped
```

## Discussion

When the [`worldMappingStatus`](/documentation/ARKit/ARFrame/worldMappingStatus-swift.property) of the session’s [`currentFrame`](/documentation/ARKit/ARSession/currentFrame) is [`ARFrame.WorldMappingStatus.mapped`](/documentation/ARKit/ARFrame/WorldMappingStatus-swift.enum/mapped), the session has produced a high-fidelity internal map of the real-world space around the device’s current position and the scene visible to the camera.

This status provides the highest reliability for relocalizing to a saved world map, provided that:

1. You call [`getCurrentWorldMap(completionHandler:)`](/documentation/ARKit/ARSession/getCurrentWorldMap(completionHandler:)) to save the world map while the status of the [`currentFrame`](/documentation/ARKit/ARSession/currentFrame) is [`ARFrame.WorldMappingStatus.mapped`](/documentation/ARKit/ARFrame/WorldMappingStatus-swift.enum/mapped).
2. When you run a new session (later or on another device) from that [`ARWorldMap`](/documentation/ARKit/ARWorldMap), the device running the new session is at a real-world position and orientation similar to that when the world map was saved.
