OS Terrain 1m DTM/DSM
1m LIDAR-derived terrain - site-level analysis, fine flood, drainage and CV pipelines.
// WHAT'S IN IT
Inside the dataset
OS Terrain 1m is a high-resolution LIDAR-derived terrain product covering most of GB at 1-metre grid spacing. Both DTM (bare earth) and DSM (with surface - buildings, vegetation) are available.
It's the right product for site-level engineering, fine-grained flood modelling, drainage design, solar PV roof analysis, and any computer-vision or analytics pipeline that needs to see terrain detail under a metre.
Key features
- 1m grid resolution
- DTM (bare earth) and DSM (with surface) variants
- LIDAR-derived
- Coverage: most of GB (we'll scope your AOI before licensing)

// COMMON USE CASES
What teams build with this
Fine flood modelling
2D hydraulic modelling at sub-metre detail.
Solar PV
Roof slope, aspect and shadowing for PV feasibility.
CV pipelines
Building height extraction, vegetation classification.
// 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.

Standards & schema
All vector datasets ship with stable identifiers (TOID/OSID/UPRN) suitable for change-aware joining. Raster datasets ship with full georeferencing metadata. We can supply schema documentation, sample files and ETL guidance on request.
// FAQ
Common questions
Do you have full GB coverage at 1m?
Coverage is high but not 100% - we will scope your AOI and confirm coverage before licensing.
DTM or DSM - which do we want?
DTM strips buildings/vegetation (use for hydraulic modelling). DSM keeps them (use for solar PV, shadowing, view analysis). We can deliver both.
How big is delivery?
A 1km tile is ~1MB; a national delivery is hundreds of GB tiled.
Can we have it streamed via API?
Yes - we can serve elevation queries via API rather than shipping rasters.
