New Zealand Elevation Models at 1-Meter Resolution from LiDAR

New Zealand's publicly owned digital elevation and surface models, available under an open license. The dataset contains 1-meter resolution grids derived from LiDAR data, organized by region and survey. It is provided as Cloud Optimised GeoTIFFs with LERC compression and accompanied by STAC metadata.

Use Cases

• Terrain analysis and 3D modeling based on high-resolution digital elevation models.
• Flood risk and hydrological modeling based on elevation data.
• Infrastructure and urban planning based on digital surface models.
• Environmental change detection based on regionally organized LiDAR-derived grids.

Strengths

• 1-meter spatial resolution derived from LiDAR data.
• Data is organized by region and survey, providing structured access.
• Files are Cloud Optimised GeoTIFFs with LERC compression for efficient access.
• Includes STAC metadata for standardized discovery and use.

Limitations

• Point clouds are not included in the initial release.
• Row count and total dataset size are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
