Melbourne 3D Textured Mesh With 7.5cm Ground Sample Detail

A 3D textured mesh representing buildings, trees, and terrain across the City of Melbourne municipality, captured in May 2018. The model is provided in .obj format with .mtl and .jpg texture files, split into geo-referenced tiles with levels of detail from L13 to L20. Data capture used a 7.5cm ground sample distance for spatial accuracy.

Use Cases

• Generate 3D city visualizations and simulations using the .obj files and .jpg image textures.
• Analyze urban features like building footprints and vegetation density from the textured mesh tiles.
• Integrate tile geometry with real-world coordinates using the metadata.xml origin coordinates for GIS applications.
• Assess model detail for specific areas by comparing L13 to L20 level-of-detail .obj files.

Strengths

• High-resolution capture with 7.5cm ground sample distance.
• Model includes multiple levels of detail, from L13 to L20, for flexibility.
• Complete spatial coverage of the City of Melbourne municipality via tiled data.
• Provides geo-positioning metadata and a Tile_Index.kml for spatial reference.

Limitations

• Dataset is a single snapshot from May 2018 and may not reflect current city conditions.
• Large file size (9.7GB ZIP) requires significant storage and processing capability.
• Data provider disclaimer notes potential for errors, omissions, or unavailability.
