From point cloud to city model.

Feed LiDAR and building footprints — automatic LoD1.2 / 1.3 / 2.2 meshes powered by the roofer engine behind the Dutch 3D BAG. Plus forestry LiDAR toolkit and Gaussian splat pipeline.

Building reconstruction

The 3DBAG engine, on your desktop

roofer + LiDAR + footprints → LoD1.2 / 1.3 / 2.2 CityJSONSeq as native mesh graphics. Optional CLI — 503 if absent; app unaffected.

LoD1.2 / 1.3 / 2.2

Guided Tools → Roofer workflow; async jobs ~1–10 min per city block.

FUSION/LDV

30-command forestry toolkit — ground filter, canopy, tree segmentation.

Gaussian splats

Postshot or COLMAP+OpenSplat — photos/video → splat on your hardware.

iTowns + Spark viewer

Splats + OGC 3D Tiles, camera-synced to the ArcGIS SceneView.

Honest by design

Optional CLI, clean licensing

roofer GPLv3 invoked as separate process — not bundled
Inputs: LAS/LAZ/COPC + footprint GPKG
MaxBuildings cap (default 5000) for map performance
Air-gapped viewer — three/iTowns/Spark vendored locally
