OS Terrain 5
5m DTM with 0.5m vertical accuracy - the workhorse for landscape and flood analysis.
// WHAT'S IN IT
Inside the dataset
OS Terrain 5 is a Digital Terrain Model at 5-metre grid spacing with 0.5m typical vertical accuracy. It's the standard product for regional landscape, slope and flood analysis where 1m LIDAR is overkill or unavailable.
Delivered as gridded raster (GeoTIFF) or as contours (GML/GeoPackage), it's the most commonly licensed terrain product after open-data Terrain 50.

// COVERAGE & LICENSING
Licensed to fit, not bloat.
Every licence is sized to your actual usage. We'll always recommend the smallest coverage tier that solves your problem - and scale up as you do.
Single site
A specific site or property - typical for small consultancies and one-off projects.
Regional
A council area, county, region or custom polygon - typical for LAs, utilities and dev firms.
National (GB)
Full GB coverage - for prop-tech, insurance, multi-region utilities and national operators.
Bespoke
Custom AOI, mixed cadence, multi-tenant or co-built licence. We scope under NDA.

// FAQ
Common questions
Is this LIDAR-derived?
Terrain 5 blends LIDAR-derived data with photogrammetric and surveyed sources to give national coverage at 5m.
Should we use Terrain 5 or Terrain 1m?
Terrain 5 is right for regional/national workloads. Terrain 1m is right when you need fine vertical detail (e.g. roof drainage, micro-flood).
Can we get just contours?
Yes - contours are available as GML or GeoPackage at standard intervals.
How big is a national delivery?
A full GB Terrain 5 GeoTIFF is roughly tens of GB. We typically deliver tiled.
