England LIDAR Point Cloud Archive With Temporal Coverage

1998 to present LIDAR surveys across England, with point cloud data available from 2006. The archive contains hundreds of millions to billions of 3D points with x, y, z coordinates and component attributes, produced by the Environment Agency. Data is organized into 5km ZIP files containing LAZ files aligned to the Ordnance Survey grid for each survey year.

Use Cases

• Create canopy height models using classified 'surface objects' points and elevation data.
• Generate custom intensity rasters from the laser return intensity component attribute.
• Analyze coastal erosion by comparing x, y, z points from multiple surveys of the same area over time.
• Derive bespoke digital surface models (DSM) from the raw point cloud for specific sites.
• Assess average point density per tile for survey quality control and resolution analysis.

Strengths

• Hundreds of millions to billions of highly accurate 3D points provide dense spatial coverage.
• Surveys span from 1998 to present, with point cloud data available from 2006, offering long-term temporal analysis potential.
• Points include component attributes beyond x, y, z coordinates, such as classification and intensity.
• Data is aligned to the standardized Ordnance Survey grid for consistent georeferencing.

Limitations

• No matching point cloud may exist for every derived surface model product due to historic archiving.
• Classified 'ground' points in the cloud do not match the final edited digital terrain model (DTM).
• Specific row counts, file sizes, and complete geographic coverage details are not provided.
