The 3D surface combines LINZ's coastal LiDAR DEM, where available, with its national land elevation tiles. Coastal data is read directly from LINZ's cloud-optimised GeoTIFFs. Aerial imagery is supplied by LINZ Basemaps.
The coastal DEM supplies the 3D elevation values at and below 0 m. Positive coastal DEM values are filtered out, so the national land elevation surface supplies the land. Missing elevation values remain transparent. Vertical exaggeration changes how the terrain appears.
Click the map to ask the LINZ Data Service for the coastal DEM value at that location. Contours are drawn at 1 m intervals from −50 m to 0 m, with heavier lines every 5 m. The optional coastline is LINZ's mean high water springs reference line; it may differ from the DEM's shoreline.
