Sydney 3D model
Sydney CBD and Circular Quay — DXF + STL

The Sydney CBD running down to the harbour. Australia has its own terrain chain, so this sits between the 1 m lidar regions and the 30 m global fallback at a 5 m DEM.

What to expect here
- Geoscience Australia 5 m lidar DEM is tried first, with the 1-second SRTM product behind it.
- Harbour edge with a complex, non-straight coastline — a good check of how water boundaries are cut.
- Southern hemisphere: the export projects to a southern UTM zone (EPSG 327xx), which trips up some CAD importers that assume northern zones.
Where the data comes from
Terrain sources are tried in order and the first one that actually covers the region wins, so the resolution you get depends on what has been flown here:
- 1 Geoscience Australia lidar DEM 5 m
- 2 Geoscience Australia SRTM 1-second ~30 m
- 3 Copernicus DEM GLO-30 30 m
Buildings, roads, water and landuse come from Overture Maps, which is global and openly licensed. Building heights are used where the source has them.
