NSW Elevation and Depth Theme: LiDAR and Contour Data for New South Wales

New South Wales elevation and depth data includes measurements of the Earth's surface above or below a vertical datum. Data is collected using sensors like laser, sonar, radar, and optical, and includes derived products like spot heights, raster surfaces, contours, triangulated irregular networks, and digital elevation models. The dataset is provided by Spatial Services (DCS) and was last updated on 2026-05-17.

Use Cases

• Generate flood risk models based on digital elevation models and contour data.
• Analyze terrain for construction planning using spot heights and relative heights.
• Create 3D visualizations of landscapes using point cloud data derived from LiDAR and photogrammetry.

Strengths

• Data aligns with the national GDA2020 standard, improving accuracy and compatibility.
• Includes multiple data types like historical contours (2m, 10m, 20m), current 2m contours, spot heights, and point clouds.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
