Data comprises:
• 400+ GeoTIFF tiles in NZTM2000 projection, merged from a variety of source surveys and tiled into the LINZ 1:50,000 tile layout.
Vertical Accuracy Specification is +/- 0.2m (95%).
Horizontal Accuracy Specification is +/- 1.0m (95%).
Vertical datum is NZVD2016.
Also available on:
• Basemaps as a Terrain-RGB service.
• NZ Elevation - Registry of Open Data on AWS, specifically at s3://nz-elevation/new-zealand/new-zealand/dem_1m/2193/. This is the data source and at this location it is LERC compressed and made available as Cloud Optimised GeoTIFFs.
Additional metadata from the S3 source:
• STAC Collection
• Capture Dates
• Capture Area
Please note that this dataset is manually imported into the LINZ Data Service after the S3 source is updated. It may not reflect the most recently published data in S3. Check the History tab to determine the most recent LINZ Data Service publish date. S3 source update dates are provided in the STAC Collection metadata file.
