3D Building Models for Le Sud-Ouest and Ville-Marie Boroughs

Montreal's Le Sud-Ouest and Ville-Marie boroughs are represented by a digital 3D building model in CityGML LOD2 format with textures. The dataset includes models in GML and 3DM formats, accompanied by a digital terrain model for the same territory. It was published by the Government and Municipalities of Québec.

Use Cases

• Generate realistic urban visualizations and simulations using the textured 3D LOD2 building models.
• Conduct solar potential or shadow analysis by integrating the 3D building geometry with the provided digital terrain model.
• Perform urban planning studies on building form and density for the Le Sud-Ouest and Ville-Marie boroughs.
• Convert or compare architectural data between the provided CityGML and 3DM file formats.

Strengths

• Models are provided in two standard 3D formats, CityGML and 3DM, enhancing interoperability.
• Includes a complementary digital terrain model for the same territory, providing a complete 3D context.
• Data is provided with textures, increasing visual fidelity for rendering applications.

Limitations

• The spatial scope is limited to only two boroughs within Montreal, not the entire city.
• The base model year is 2009, making the building geometry potentially outdated for current analysis.
• Specific technical details like polygon count, resolution, or coordinate reference system are not provided.
