3D Feature Extraction & Modelling

Building footprints, breaklines and CityGML LOD1 / LOD2 models digitised directly from client-supplied aerial LiDAR — accurate, attributed and ready for engineering, planning and digital-twin use.

Overview

We turn client-supplied aerial LiDAR into decision-ready 3D basemaps — every building footprint, road edge, breakline and utility feature is vectorized, attributed and delivered in the schemas your engineering, planning and digital-twin platforms already speak.

Client confidentiality

All project samples are shared with client permission. We treat every dataset as confidential and never disclose client data.

How we do it
  1. 01
    Source data intake

    Classified LiDAR, ortho imagery and — where available — oblique imagery are ingested and co-registered on a common datum and projection so every extracted feature sits on ground truth.

  2. 02
    Planimetric extraction

    Building outlines, roads, curbs, driveways, water bodies, walls and fences are digitized to the client's feature catalogue with tolerances matched to the intended CAD / GIS scale.

  3. 03
    Breaklines & surface conditioning

    Hard and soft breaklines — ridges, toe-of-slope, edge-of-pavement, streams — are digitized and integrated with the terrain model so downstream hydrology, grading and design behaves realistically.

  4. 04
    3D building modelling (LOD1 / LOD2)

    Prismatic LOD1 shells or roof-form LOD2 models are generated per CityGML, with heights, roof pitch and eaves derived from the point cloud and validated against imagery.

  5. 05
    Attribution, QA & delivery

    Every feature is attributed, topology-checked and reviewed against imagery. Deliverables ship in DGN, DWG, SHP, GeoPackage, CityGML, glTF or IFC with a documented QA report.
