3D Buildings (LOD2.2)

(Available starting October 27, 2026)

LOD2.2 3D buildings represent buildings in three dimensions, with a detailed representation of their roof structure, including features such as dormers. The walls are then created by extending the roof outlines down to the ground.

Product features :

The accurate reconstruction of 3D buildings is based on XEOS’s AI technology, patented in Canada, Europe, and the United Kingdom (2026). It is also patent-pending in the United States and Australia.

Each building is modeled in 3D to accurately represent its geometry, including:

  • The overall building volume;
  • The different roof surfaces;
  • Changes in roof slope and height.

The following attributes are associated with each building:

  • Height
  • Area (m²)
  • Number of floors

The following attributes are associated with each roof surface:

  • Area (m²)
  • Aspect (orientation relative to north)
  • Slope

The data can therefore serve as a basis for numerous 3D analyses, including:

  • 3D city modeling;
  • Photovoltaic solar potential assessment;
  • Calculation of rainwater catchment areas on flat roofs for stormwater network engineering;
  • Shadow and sunlight analysis;
  • Firefighter intervention planning in the event of a fire.

For whom :

  • Municipalities and urban forestry managers;
  • Land-use planners;
  • Architects;
  • Land surveyors;
  • Insurance companies.
