City of Melbourne 3D Textured Mesh with 7.5cm Ground Sample Distance, 2018

A 3D textured mesh representing physical features like buildings, trees, and terrain across the City of Melbourne municipality. The dataset is provided in tiled .obj files with accompanying .mtl and .jpg texture files, captured in May 2018 with a 7.5cm ground sample distance. Data is provided by City of Melbourne Open Data and includes multiple levels of detail from L13 to L20.

Use Cases

• Urban planning and development analysis based on 3D building and terrain models.
• Creating realistic visual simulations and digital twins based on textured mesh data.
• Environmental studies assessing vegetation and terrain features mentioned in the description.
• Augmented or virtual reality application development for city navigation and exploration.

Strengths

• Provides multiple levels of detail (L13 to L20) for flexible use.
• High spatial resolution with a capture pixel size of 7.5cm ground sample distance.
• Includes geospatial positioning metadata and a tile index for real-world alignment.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2026-06-28 08:06:39.379503; freshness should be verified as the capture date is May 2018.
• Data scale (e.g., number of tiles or vertices) is unspecified, which may limit suitability assessment.
