The map features do not contain every OS NGD feature type, nor the complete list of attribution available within the feature types that are included; we have purposefully only selected feature types and a subset of attribution from them that are useful for visualisation as this keeps the tiles lightweight and quick to render.

The inclusion of unique identifiers (IDs), where available, allows you to cross-reference with the full product, for example, with OS NGD API – Features. Find out more about OS NGD unique identifiers.

Update Frequency

Collection IDUpdate Frequency








Updated as and when updates are received from the authoritative bodies

Although OS NGD API – Tiles will be updated weekly, the data updates are based on the set currency of the OS NGD collections (for example, the Structure Features Collection currency is daily, whereas the Water Network Collection currency is monthly).


A collection in OS NGD API - Tiles references OS NGD Feature Type grouping. Feature types have their own data model and specifications which are not commonly shared with other feature types.
