City of Melbourne Digital Surface Model at 0.1-Meter Resolution

A terrain surface dataset representing the height of all natural and built features across the City of Melbourne municipality. Data was captured in May 2018 as GeoTIFF files with a 0.1-meter pixel resolution, referenced to the Australian Height Datum.

Use Cases

• Generate 3D city models and analyze building height distributions using elevation values from GeoTIFF tiles.
• Assess urban vegetation canopy height and coverage by extracting elevation data for non-built surface features.
• Calculate solar exposure and shadow modeling for urban planning based on the high-resolution terrain surface.
• Integrate elevation values with the provided KML tile index for precise geospatial analysis and visualization.

Strengths

• High spatial resolution of 0.1 meters per pixel for detailed surface modeling.
• Covers the entire City of Melbourne municipality, providing complete urban coverage.
• Data is provided in the standard GeoTIFF format, compatible with most GIS software.

Limitations

• The dataset is a single snapshot from May 2018 and may not reflect recent urban changes.
• The provider notes the content may contain errors, omissions, or defects despite accuracy efforts.
• The 12.0 GB download size indicates significant storage and processing requirements.
