# Known limitations

There are some known limitations for bus lane data:

* **Completeness**: Bus Lane features have been captured from aerial imagery and therefore there are some limitations to completeness. Where features are not visible from aerial imagery (for example, where they are obscured by tree cover or are not visible due to urban shading), these will not be included. You can report any bus lane omissions on the [OS Data Hub Error Reporting Tool](https://osdatahub.os.uk/apps/errors-and-omissions) for OS to investigate.
* **Linking to the Road and Path Network**: The accuracy of the linking between Bus Lane features and the Road Network is dependent on the performance of an algorithm. In areas of complex network geometry (for example, at junctions) there are limitations to the accuracy of the linking algorithm.
