OS Features API
Have you considered the benefits of the OS National Geographic Database?
OS Features API is anticipated to reach End of Life in summer 2030 and will be retired.
Its replacement, OS NGD API – Features API, is built on the latest OGC API - Features standard and offers you all of the benefits of the OS National Geographic Database (OS NGD), including:
Increased data update frequency (up-to-daily updates for many datasets)
Richer attribution
Improved data structures
A continuous series of ongoing data enhancements
What is OS Features API?
Use OS Features API to filter OS data and receive exactly what you need, as and when you need it. Buildings, roads, rivers, hospitals, playing fields, greenspaces – there are many data layers available. There are lots of options for applying spatial filters (for example, Intersects), attribute filters and even combinations. For example, you can select all buildings within a specified area of interest (a polygon feature).
Benefit from current and historical detailed and accurate data to help you generate new location-based insight. OS Features API contains OS MasterMap Topography Layer and much more, and can remove the need to download, store and manage large and complex datasets.
OS Features API gives you direct access to the detailed geometries and rich attribution of individual features. It is based on the OGC standard Web Feature Service (WFS) so is interoperable with lots of GIS software and web mapping libraries.
