City of Hobart BYDA Layers: Urban Infrastructure and Environmental Assets

BYDA Layers provide a multi-faceted geospatial inventory of the City of Hobart's built and natural environment. The dataset includes 24 distinct layers covering infrastructure like roads, stormwater networks, and electrical assets, as well as environmental features such as trees, rivers, and cadastral boundaries. This collection supports integrated urban management by linking physical assets with operational data like parking sensors and incident areas.

Use Cases

• Stormwater network modeling and maintenance planning based on Stormwater Nodes, Pipes, and Branch Connections layers.
• Urban tree canopy assessment and protection based on Significant Tree, Tree, and Significant Tree Areas layers.
• Cadastral and property development analysis based on Cadastre Parcel Boundaries and Building Footprints layers.
• Road and traffic infrastructure management based on Road Centre Lines, Road Formation, and Parking Sensors layers.
• Identifying potential hazards for excavation and construction based on Potential Underground Electrical Assets and Infrastructure Cables layers.

Strengths

• Contains 24 distinct, thematically organized geospatial layers for comprehensive urban analysis.
• Cross-platform presence on data.gov.au indicates official status and sustained maintenance.
• Includes both static assets (buildings, trees) and dynamic operational data (parking sensors, incident areas).

Limitations

• Critical metadata is missing: row counts, file sizes, and specific column schemas are not provided for any layer.
• The license is listed only as 'other', which creates ambiguity for reuse and redistribution.
• A future 'last updated' date (2026-04-11) appears in two entries, suggesting a metadata error that affects trust in freshness indicators.
