3D Models API

Every Belgian building
as a 3D model

Automated 3D reconstruction based on LiDAR point clouds. LOD2 level of detail with roof shapes, neighbourhood context and multiple export formats.

Interactive 3D viewer

Rotate, zoom and view the 3D model from any perspective. This is a live example of a building in Heusden-Zolder.

From point cloud to 3D model

Three automated steps transform raw LiDAR data into a detailed 3D building model.

1

LiDAR point cloud

High-quality LiDAR data for all of Belgium. Millions of measurement points per square kilometre for accurate height and shape data.

LiDAR All of Belgium DSM + DTM
2

Taxon 3D engine reconstruction

Our in-house 3D engine processes the point cloud together with building footprints into an accurate LOD2 3D model with recognisable roof shapes.

3D model output

The result is available in several standard 3D formats. Ready to integrate into your own application, viewer or analysis software.

GLB OBJ DAE STL

Use cases

From roof analysis for solar panels to volume calculation for valuation.

Roof analysis

Automatic roof area calculation based on the 3D model. Ideal for solar panel installers and energy advisers to quickly assess potential.

Volume calculation

Exact building volumes for valuation, renovation planning and permit applications. More accurate than manual measurements thanks to LiDAR precision.

Visual valuation

3D context for better property valuation. View the building and the neighbourhood in three dimensions for a more complete picture during the valuation.

Technical specifications

Everything you need to know about the 3D reconstruction engine and its output.

LOD2 level of detail

3D geometry with individual roof planes and roof shapes

Roof shape recognition

Gable, hip, flat, mansard and complex roofs

Neighbouring buildings context

Surrounding buildings within a 40m radius, added automatically

Parcel boundaries

Cadastral parcel boundaries as a 3D overlay

Export: GLB/OBJ/DAE/STL

Interactive CesiumJS viewer

Built-in 3D viewer with orbit controls and terrain

API integration

A single API call for a complete 3D building model with metadata, parcel boundaries and neighbourhood context.
