Spot Height: NSW Elevation and Depth Points for Geospatial Analysis

Spot Height is a point feature class representing individual surveyed elevation points across New South Wales. The dataset is part of the state's authoritative Foundation Spatial Data Framework and was initially captured from stereoscopic aerial photography at scales of 1:25,000, 1:50,000, and 1:100,000. It is provided by Spatial Services, a business unit of the Department of Customer Service NSW, and has been updated to the GDA2020 geodetic standard.

Use Cases

• Conducting flood risk assessment and hydrological modeling based on terrain elevation.
• Supporting safe navigation for aeronautical and road planning using surveyed height points.
• Informing climate change adaptation and natural hazard risk assessment with foundational elevation data.
• Defining maritime and administrative boundaries using an authoritative elevation reference.
• Aiding natural resource exploration and environmental management with terrain information.

Strengths

• Aligned with the national GDA2020 geodetic standard, improving accuracy and compatibility.
• Part of the authoritative NSW Foundation Spatial Data Framework, suggesting official provenance.
• Data captured from stereoscopic aerial photography at multiple scales (1:25k, 1:50k, 1:100k).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale projects.
• Data currency is listed as 01/01/3000, which is a placeholder and obscures actual freshness.
