Manhattan 3D model
Midtown Manhattan block cluster — DXF + STL
The densest region in the catalogue: a 590 × 780 m patch of midtown Manhattan holding several hundred buildings. Terrain here is nearly flat, so the model is almost entirely built mass — a good reference for checking building heights and footprint fidelity.

What to expect here
- 411 building footprints and 405 road segments measured in 0.46 km² — roughly 900 buildings per square kilometre.
- Effectively flat: the interesting geometry is vertical, which makes this a useful test case for LOD1 height quality rather than terrain.
- US coverage, so USGS 3DEP 1 m lidar is tried first even though the relief barely uses it.
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 USGS 3DEP lidar 1 m
- 2 USGS 3DEP 1/3 arc-second ~10 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.
