Environment Agency - England LiDAR-derived DEMs

This dataset contains Environment Agency LiDAR-derived Digital Elevation Models for England, both Digital Terrain Models and Digital Surface Models. These have been taken from the original [National LiDAR Programme data](https://www.data.gov.uk/dataset/f0db0249-f17b-4036-9e65-309148c97ce4/national-lidar-programme), and converted to Cloud Optimized GeoTIFF format with STAC catalogues. The original data is released under the Open Government License, which allows redistribution with attribution, an

What's in it

Data offered docs-verified: DTM (Digital Terrain Model) · First Return DSM (Digital Surface Model)
Coverage docs-verified: England
Resolution llm-inferred: 1 m
Formats docs-verified: Cloud Optimized GeoTIFF (COG) · STAC JSON · STAC GeoParquet
Access docs-verified: Public; anonymous HTTPS/S3 access via source.coop; Open Government Licence (redistribution with attribution)

Useful for

Use cases llm-inferred: FRA baseline ground levels and terrain inputs for flood modelling · Drainage strategy catchment delineation and flow-path analysis from 1 m DTM · Earthworks and cut/fill volume estimation by differencing against site surveys · Vegetation and built-form height estimation from DSM minus DTM
Audience llm-inferred: flood consultants · drainage engineers · civils engineers · hydrologists · GIS analysts

Limitations

Constraints llm-inferred: Released with no guarantees or warranty · LERC compression is not available for the DSM; DSM is DEFLATE only · DSM is first-return, so it includes vegetation and buildings rather than bare earth · Static STAC catalogues are not well supported by stackstac or odc-stac; lazycogs or GDAL GTI recommended · Requires GDAL (GTI driver) or Python tooling to query STAC GeoParquet efficiently
