Dataset description

Terrain (DTM) & Surface (DSM) elevation models of river basins derived from airborne LIDAR survey systems. A Digital Terrain Model (DTM) is a digital file consisting of a grid of regularly spaced points of known height which, when used with other digital data such as maps or orthophotographs, can provide a 3D image of the land surface. This data is typically provided in tiles of 1km x 1km, each containing elevations in a 1m x 1m grid. Tiles are grouped and can be downloaded by area as shown on the index ‘River Basin LIDAR-Coverage Map’. Data acquired in 2009 & 2010 also contains Point Cloud files, a closely spaced (0.2m) irregular grid of elevations from which the 1m x1m grids were derived. By download or use of this dataset you agree to abide by the Open Government Data Licence. This data is not a supported LPS product, supporting documentation has been provided to assist / offer guidance on the data itself.

Yes. Selected APIs include a free API quota, so your team can validate coverage, freshness, response shape and workflow fit before asking for a production plan.

Often yes, but usage rights depend on the source license and dataset. We surface source, license and update metadata where available, and can help review terms before a production integration.

Maintained APIs include update metadata where available. For production integrations, we can add history, monitoring and push updates so changes are easier to detect and act on.

Production APIs can add SLA, stable identifiers, versioning support, history, push updates and direct support around the data your product or AI workflow depends on.
