Commercial blended land + bathymetry. Feature-preserving coastlines.
The world’s first commercial blended land-and-bathymetry terrain platform, engineered with attractive coastal collaring and feature-preserving coastlines. Stream a continuous global surface built for serious GIS, simulation and enterprise geospatial infrastructure.
QuantizedMesh.com is designed as a portable terrain foundation rather than a viewer-specific product. Deploy the same global terrain through CesiumJS, MapLibre, deck.gl or iTowns — choosing the rendering ecosystem that best fits globe visualization, web mapping, analytical overlays or immersive 3D geospatial applications.
The native home of Quantized Mesh. Stream global terrain into an industry-leading 3D globe with progressive level-of-detail, terrain lighting, watermask support and globe-scale interaction.

Explore MapLibre demo ↗ 03Pair global terrain with a high-performance geospatial visualization stack designed for rich data layers, interactive analysis and GPU-accelerated scenes.
Explore deck.gl demo ↗ 04See Quantized Mesh inside an extensible 3D geospatial environment built for globe, terrain and layered spatial content across demanding browser applications.
Explore iTowns demo ↗The terrain engine is built around adaptive triangulation rather than a single rigid meshing strategy. Regular Grid, Feature-Aware Grid TIN and Adaptive Delaunay options let geometry respond to terrain character while retaining efficient streaming and seamless tile continuity.
Multiple TIN strategies allow terrain construction to preserve meaningful ridgelines, cliffs, valleys and morphology without spending equal geometric complexity everywhere.
Per-vertex normals provide richer surface curvature and realistic shading cues, giving modern globe engines the information they need for detailed terrain lighting.
Accurate land/water classification is designed to preserve intricate shoreline detail, small islands and inland water features instead of reducing coastlines to coarse transitions.
Coverage spans 90° north to 90° south, with progressive streaming from global overview levels through enhanced regional detail where higher-resolution source coverage is available.
In these representative side-by-side views, QuantizedMesh.com bathymetry closely matches the terrain character visible in EMODnet, while the coastal collaring removes unnatural cliffs at land-to-water transitions. The comparison highlights the level of seafloor structure retained by the production-ready Quantized Mesh surface.

Rather than exposing disconnected elevation products, the platform evaluates and combines multiple DEM and bathymetry sources into a unified terrain experience. Coverage-aware source selection, validation and quality controls hide the source complexity from the final terrain consumer.
Primary high-resolution land elevation and the main global terrain foundation.
High-quality terrain coverage used within the multi-source integration strategy.
Broad-area fallback and continuity where the terrain engine requires resilient coverage.
Supplementary regional elevation used to strengthen source availability and terrain integration.
Global bathymetry and ocean terrain, integrated with terrestrial elevations for continuous land-to-seafloor geometry.
The integration layer is designed to maximise worldwide availability while presenting a consistent product across hemispheres and source boundaries.
Terrain generation happens ahead of production delivery. Multiple elevation sources are selected, validated and integrated; neighbour-aware edge management protects tile continuity; coastline and bathymetry processing establish a coherent global surface; and the resulting geometry is encoded as native Cesium Quantized Mesh.
The deployment therefore serves pre-generated compressed binary terrain instead of paying the computational cost of creating terrain on demand. The result is predictable streaming behaviour and lower runtime infrastructure complexity.
See the deployment model →Coastline morphology is treated as a core terrain feature. Authoritative terrestrial elevations and GEBCO bathymetry are fused into a visually continuous surface while preserving recognisable shoreline geometry and reducing coastal artefacts.
Shorelines, islands, archipelagos, estuaries, canals and fjords retain recognisable geometry instead of being blurred by crude transitions.
Neighbour-aware processing and edge management are designed to minimise visible tile seams and coastline artefacts.
The terrain surface continues naturally from mountains and coastal shelves into shallow water and the ocean floor.
Approximately 850 GB of pre-generated terrain is delivered from a portable SQLite terrain database, simplifying hosting, replication and distribution while keeping runtime terrain generation out of the production path.
Deploy behind scalable terrain services and distribution infrastructure for high-volume concurrent access.
Keep the entire global terrain package within controlled enterprise infrastructure with straightforward backup and replication.
Portable storage supports isolated and field environments where dependable terrain must remain available without external data services.
Pre-generated terrain reduces server-side generation overhead, supporting low CPU utilisation and consistent high-throughput streaming behaviour.

}Quantized Mesh combines compact vertex and triangle data with terrain-specific extensions. Oct-encoded vertex normals enrich lighting, watermask data distinguishes land and water, horizon occlusion metadata supports globe-scale rendering efficiency, and progressive quadtree levels-of-detail keep delivery appropriate to the viewer’s distance.
The platform is designed for professional applications that value dependable worldwide terrain, visual consistency, deployment control and predictable streaming behaviour.
A consistent global surface for city, infrastructure and planetary-scale 3D environments.
Controlled deployment options for simulation, visualisation and geospatial mission environments.
Progressive terrain suitable for terrain-aware visualisation and synthetic-world applications.
Land, coastline and bathymetry brought together in one continuous terrain surface.
Pre-generated global terrain that supports repeatable scenarios and predictable rendering behaviour.
High-performance 3D context for GIS, infrastructure planning and environmental modelling.
Bathymetric mesh output is sampled directly against the GEBCO reference surface. This completed zoom-10 validation block tested 4,326,400 elevation samples across 1,024 terrain tiles with zero failed tiles and zero invalid samples.
An MAE of 0.7449 m and RMSE of 1.3784 m indicate very close agreement with GEBCO while allowing the controlled smoothing expected from a production terrain mesh. The modest −0.6500 m bias shows a slight tendency for the smoothed mesh to sit below the reference surface.
| Threshold | Samples within threshold | Share |
|---|---|---|
| ≤ 0.5 m | 3,139,358 | 72.56% |
| ≤ 1 m | 3,607,670 | 83.39% |
| ≤ 2 m | 3,913,520 | 90.46% |
| ≤ 5 m | 4,207,624 | 97.25% |
| ≤ 10 m | 4,303,101 | 99.46% |
| ≤ 20 m | 4,322,745 | 99.92% |
The distribution is tightly concentrated around the GEBCO source: 72.56% of all samples are within 0.5 m, 83.39% are within 1 m, 97.25% are within 5 m and 99.92% are within 20 m. That is a strong fit for a streamed production surface where smoothing, seam-safe triangulation and coastal blending intentionally prioritise continuity while retaining close source conformity.
The 143.4108 m maximum is an isolated tail value rather than representative behaviour. For production QA it should remain visible and traceable, but the P95 of 3.6 m, RMSE of 1.3784 m and MAE of 0.7449 m are more representative of normal agreement across this validation block.
