3D Processing
Since 2017, Geokali has been combining laser scanning and photogrammetry to produce digital twins.
By using state-of-the-art tools and controlling every stage of processing, this approach ensures highly accurate geometry and fine textures, enabling detailed inspection even in difficult-to-access areas.

Notre-Dame de Dijon, western façade — from raw hybrid 3D model to textured rendering
Geokali’s textured 3D models are fully georeferenced measurement tools — enabling plan restitution and morphological monitoring — while also providing a solid basis for understanding and documenting each site.
The models are made easily accessible through an online platform, usable on standard computers or smartphones.
