Coastal Infrastructure Lines for Western Australia

A spatial dataset of Department of Transport-maintained coastal infrastructure lines in Western Australia, derived from aerial imagery interpretation. The data includes roads identified in the DoT asset management database, but excludes certain assets like signs and equipment. Locations are not guaranteed for current status or safety.

Use Cases

• Analyze spatial distribution of DoT-maintained roads along the Western Australian coast for infrastructure planning
• Integrate coastal road line features with other spatial datasets for regional transport network modeling
• Use the line geometry to assess coastal access points and connectivity for engineering studies

Strengths

• Data is provided by the authoritative Geographic Information Management team of the Department of Transport
• Includes only assets formally recorded in the DoT asset management database, ensuring an official source
• Available via multiple access methods including WFS, WMS, and an ArcGIS Server API

Limitations

• Dataset is incomplete, excluding significant assets like signs, services, and plant & equipment
• Locations are generated from aerial imagery interpretation and current status is not guaranteed
• Explicitly not intended for navigation or hazard identification, limiting operational applications
