City of Melbourne 3D Textured Mesh with 2cm Ground Sample Distance

May 2020 capture of a high-resolution 3D textured mesh representing all physical features across the City of Melbourne municipality. The data, provided by City of Melbourne Open Data, is delivered in ESRI SLPK and Wavefront OBJ formats, split into geo-referenced tiles. It features a 2cm ground sample distance and estimated spatial accuracies of 0.05m (X), 0.6m (Y), and 0.04m (Z).

Use Cases

• Create realistic 3D urban visualizations based on the textured mesh of buildings, trees, and terrain.
• Perform geospatial analysis of urban features based on the tiled, geo-referenced mesh data.
• Develop augmented reality applications using the high-resolution 3D model of the city.
• Simulate environmental impacts (e.g., shadow analysis, wind flow) based on the detailed 3D geometry.
• Support urban planning and development assessments using the accurate spatial representation.

Strengths

• High-resolution capture with a 2cm ground sample distance.
• Provides estimated spatial accuracies for X, Y, and Z coordinates.
• Covers the entire City of Melbourne municipality and is available in multiple standard 3D formats (SLPK, OBJ).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
