Building Roofprints with Height and Construction Year

Roof area outlines for buildings were identified and measured using LiDAR analysis and photogrammetry. The dataset includes attributes for approximate building height in meters and the year of construction. It is produced and maintained by the City of Greater Geelong, with a recent update in April 2026.

Use Cases

• Estimate solar panel potential and urban heat island effects by analyzing roofprint area and building height.
• Model population density and urban sprawl by aggregating building footprints and construction year data.
• Assess flood or fire risk for individual structures using the building height and year of construction attributes.
• Train computer vision models for building detection and segmentation using the derived roofprint geometries.

Strengths

• Includes multiple derived attributes like building height and construction year.
• Data is derived from a combination of LiDAR and photogrammetry, providing a detailed measurement method.
• Available in multiple standard geospatial formats including GeoJSON and SHP.

Limitations

• The specific number of building records (rows) is not provided.
• Data accuracy is subject to the limitations of the source LiDAR and photogrammetry, as noted in the disclaimer.
