England LIDAR Surface Elevation Tiles With Survey Timestamps

LIDAR-derived Digital Surface Model raster tiles for England, capturing heights of terrain, buildings, and vegetation. The Environment Agency archive contains site-specific surveys conducted since 1998, with some coastal areas surveyed multiple times. Data is available at resolutions of 25cm, 50cm, 1m, and 2m, packaged in 5km GeoTIFF zips.

Use Cases

• Analyze urban growth by comparing building heights from DSM tiles across different survey timestamps.
• Model flood inundation using the terrain and surface object elevation data with its +/-15cm vertical accuracy.
• Monitor coastal erosion by comparing surface elevation from repeated surveys in the coastal zone.
• Assess vegetation canopy change over time using the last-return LIDAR signal that includes object heights.

Strengths

• Vertical accuracy of +/-15cm RMSE for all LIDAR data.
• Multiple available resolutions: 25cm, 50cm, 1m, and 2m.
• Surveys conducted since 1998, providing a multi-decadal archive.
• Specific coastal zones have been surveyed multiple times for temporal analysis.

Limitations

• Spatial coverage is limited to England, not the entire UK.
• Specific row/record counts and total file size are unknown.
• Data transformation and geoidal model vary by survey time period, requiring careful integration.
