About GLB
Map of Hunan in GLB — an export of real OpenStreetMap data for the selected area.
GLB is the binary variant of glTF format. The entire 3D scene (geometry, materials, textures) is packed into a single compact file. Faster loading and smaller size compared to glTF with separate resources.
Which layers are in the file
The set of layers depends on the selected area.
What this file will not contain
In GLB for Hunan the following will not travel: 164 986 km of roads, 1 417 water features, 31 352 km² of green areas, 14 415 points of interest — the format prints solid volumes extruded from building outlines, and other layers are not part of the model.
File size
The expected size of the GLB file for Hunan is about 339 KB; the exact size depends on the chosen layers and area.
GLB file passport
Estimated from the place's OSM data; exact figures are in the file after the build.
- Triangles in the model (estimated): ≈ 12
- Buildings (96 281) are not included in a file at this scale — for 3D houses, order an area smaller than 25 000 km²
- Model size at 1:5 000: 108 136 × 121 371 mm
Losses: not in the file: Buildings 96 281.
Build recipe: glTF 2.0 (.glb — a single binary file, .gltf — JSON with embedded buffers): buildings extruded by height or building:levels × 3 m, material by building type; frame 541 × 607 km.

How to use GLB for Hunan
- Windows 10 and 11 — open it with a double click in the built-in "3D Viewer": you can spin the model around without installing anything.
- Blender (free) — File → Import → glTF 2.0; the scene arrives with materials, and from there it is lighting, camera and rendering.
- three.js and Babylon.js — GLTFLoader loads the .glb directly; the file is self-contained, there are no separate assets to place alongside.

FAQ: GLB for Hunan
Which layers are included in the 3D model?
Only building geometry. Roads, landuse, water, and boundaries are not included in the 3D scene.
Is terrain relief included?
Yes, where elevation data (DEM) covers the area: buildings sit on the terrain and the top of the base follows the slope. Without DEM the model stands at z = 0. A bare relief surface is the separate Terrain Mesh format.
What's the difference between GLB and glTF?
GLB is everything in one binary file. glTF is JSON + separate resources. GLB is more compact and loads faster.
Can I open GLB in Windows?
Yes, Windows 10/11 has a built-in 3D Viewer that supports GLB.
At what scale does the model arrive?
In meters, with the origin at the center of the selected area. The buildings stand on a plane, so the model can be measured right away and compared with real dimensions.
