What It Is
Gaussian splatting just got an open standard — a breakthrough in 3D scene representation that fundamentally changes digital mapping.
Google Earth has looked the same for 15 years. This is the year that changes — and not just for humans.
What Is Gaussian Splatting?
A technique for representing 3D scenes using millions of tiny 3D Gaussian “splats” — ellipsoids that blend together to create photorealistic views from any angle. Unlike traditional 3D models (meshes with textures), Gaussian splats are:
- Rendered in real-time — no polygon limits
- Photorealistic — captures lighting, reflections, translucency
- View-independent — looks correct from any angle
- Compact — efficient to store and stream
Why It Matters for Mapping
| Before | After Gaussian Splatting |
|---|---|
| Flat satellite imagery | Full 3D photorealism |
| Textured 3D meshes (slow) | Real-time Gaussian splats |
| Human-only consumption | AI-readable 3D world models |
| Proprietary formats | Open standard |
The “not just for humans” part is key — an open standard means AI agents can read, navigate, and reason about 3D space the same way they read text.
