Building Roofprints with Height and Construction Year for Geelong

Building outlines representing roof areas for the City of Greater Geelong, derived from LiDAR and photogrammetry. The dataset includes attributes for approximate building height in metres and year of construction. It is published and maintained by the City of Greater Geelong, with a last recorded update in April 2026.

Use Cases

• Estimate urban heat island effects by analyzing building height and roof area distribution across the city.
• Model population density by correlating building footprint size and construction year with census data.
• Assess solar panel installation potential across rooftops using geospatial roofprint data.
• Analyze urban development trends over time by filtering buildings based on their construction_year attribute.
• Calculate approximate building volume for energy demand modeling using the building height and footprint area.

Strengths

• Data is derived from authoritative remote sensing methods: LiDAR analysis and photogrammetry.
• Includes multiple key attributes per feature: building outline, approximate height, and construction year.
• Available in several standard geospatial formats including GeoJSON, SHP, and WFS for interoperability.
• Published under a permissive CC-BY-4.0 license, allowing for wide reuse with attribution.

Limitations

• The building heights are described as 'approximate', indicating potential measurement inaccuracies.
• Specific sample size, total row count, and spatial resolution details are not provided.
• The disclaimer notes the data is provided without warranty, implying potential undiscovered errors.
