// WHAT'S IN IT

Inside the dataset

OS Terrain 50 is a 50-metre national DTM. It's the right choice when you need elevation context across a region or the whole country - basemap relief shading, summary statistics, dashboard backdrops - without the storage and compute cost of finer products.

We license Terrain 50 alongside our other products under enterprise terms even though it has open-data variants, because most enterprise buyers want it bundled with bespoke regional cuts and SLA-backed delivery.

Key features

  • 50m grid resolution
  • National coverage
  • Available as raster or contours
  • Lightweight - easy to host nationally

// FAQ

Common questions

Isn't Terrain 50 free under OS OpenData?

Yes - but enterprise customers often want it delivered alongside paid products under one contract, with bespoke clipping, hosting and SLA. That's what we provide.

Should we use Terrain 50 or Terrain 5?

50 is for national/regional context; 5 is for engineering work; 1m is for site-level analysis.

Do you host it for us?

Yes - we can serve it from R2 as PMTiles or as raster tiles via our API.
