NSW Spot Height Elevation Points from Aerial Survey

Spot Height is a point feature class representing individual surveyed elevation points on the earth's surface for New South Wales. The data was initially captured at 1:25,000, 1:50,000, and 1:100,000 scales from stereoscopic aerial photography. It is provided by Spatial Services, a business unit of the Department of Customer Service NSW, as part of the Foundation Spatial Data Framework.

Use Cases

• Support safe hydrographic, aeronautical, and road navigation based on elevation points.
• Inform climate science and climate change adaptation studies based on terrain data.
• Aid emergency management and natural hazard risk assessment based on surface elevation.
• Assist in environmental and water management planning based on topographic features.
• Define maritime and administrative boundaries based on surveyed elevation points.

Strengths

• Data is part of the authoritative NSW Elevation and Depth Theme within the Foundation Spatial Data Framework.
• Points were captured from stereoscopic aerial photography at scales of 1:25,000, 1:50,000, and 1:100,000.
• The dataset supports a wide range of applications including navigation, climate science, and emergency management.

Limitations

• The service uses the GDA94 spatial reference, which may cause misalignment in GDA2020 environments and is scheduled for retirement.
• Column-level documentation is absent; field semantics must be inferred after accessing the service.
• The data currency date is listed as 01/01/3000, which is likely a placeholder and requires verification.
