Simplified Road Centerlines for Western Australia Display

Landgate's Roads (Simplified) dataset is a modified road centerline layer derived from the medium scale Topographic GeoDatabase, excluding proposed roads. It is developed for display purposes only, with fully attributed data available in separate Landgate layers.

Use Cases

• Visualize simplified road networks for cartographic display using the derived centerline geometry.
• Integrate the display-optimized road layer as a base map for thematic mapping applications.
• Compare this simplified layer with the fully attributed Roads (LGATE-012) layer to assess generalization for specific use cases.

Strengths

• Derived from the authoritative Landgate Topographic GeoDatabase (TGDB) Road segment layer.
• Excludes proposed roads, providing a snapshot of existing infrastructure.
• Available in multiple geospatial formats including GeoJSON, SHP, and Geopackage for interoperability.

Limitations

• No data dictionary is available, limiting understanding of attribute schema.
• Data is heavily modified and intended for display only, not for analysis requiring full attribution.
• Sample data and specific row/column counts are unavailable for assessing dataset scale.
