BYDA Layers: Urban Infrastructure and Cadastre for Hobart

BYDA Layers provide 23 distinct geospatial datasets covering the physical and administrative fabric of Hobart, Australia. This collection includes road networks, stormwater systems, building footprints, cadastral boundaries, and environmental features like significant trees. The data is maintained by the City of Hobart's GIS team and is available through multiple formats for integration into mapping and analysis systems.

Use Cases

• Urban planning analysis based on building footprints and cadastre parcel boundaries.
• Stormwater network modeling and maintenance planning based on pipe, node, and branch connection layers.
• Road asset management and traffic studies based on road centre lines and formation data.
• Urban forestry and environmental management based on significant tree and tree area layers.
• Utility location and conflict detection based on infrastructure cable and potential underground electrical asset layers.

Strengths

• Contains a wide range of 23 integrated geospatial layers for comprehensive urban analysis.
• Maintained and published by the authoritative local government source (City of Hobart).
• Available in multiple standard geospatial formats (GeoJSON, KML, CSV, ZIP, ArcGIS REST API) for interoperability.

Limitations

• Critical metadata is missing: no row counts, file sizes, or specific column schemas are provided for any layer.
• The listed 'last updated' date of 2026-04-11 is in the future, indicating a potential metadata error that casts doubt on data freshness.
• License is listed only as 'other', requiring users to investigate terms before use.
