BYDA Layers: Urban Infrastructure and Environmental Assets for Hobart

City of Hobart's BYDA Layers provide a detailed geospatial inventory of over 20 distinct urban asset classes, from stormwater pipes and electrical cables to significant trees and parking sensors. This dataset serves as a foundational digital twin for municipal infrastructure and environmental management. It integrates cadastral boundaries with physical assets, supporting operational and planning functions for the local government.

Use Cases

• Stormwater network modeling and maintenance planning based on stormwater nodes, pipes, and branch connections.
• Urban tree canopy management and protection based on significant tree and tree area layers.
• Utility coordination and excavation planning based on potential underground electrical assets and infrastructure cables.
• Property and land use analysis based on cadastre parcel boundaries and building footprints.
• Traffic and parking management based on road centre lines and parking sensor locations.

Strengths
