Acid Sulfate Soils Risk Maps for Coastal NSW

128 map sheets detail the risk of Acid Sulfate Soil occurrence along the New South Wales coast at a 1:25,000 scale. The dataset provides maps of elevation, landform process groups, and landform elements for the mapped area, and was revised in 1997. It was co-funded by the Natural Resources Audit Council and is published by the NSW Department of Climate Change, Energy, the Environment and Water.

Use Cases

• Assess land development risk based on mapped Acid Sulfate Soil probability classes.
• Plan coastal rehabilitation projects based on landform process group and elevation data.
• Identify areas with Pleistocene sediments or ASS scalding for targeted environmental management.

Strengths

• Covers 128 map sheets at a detailed 1:25,000 scale.
• Includes multiple thematic layers: elevation, landform process groups, and landform elements.
• Published under a permissive CC-BY-4.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The core mapping was completed in 1997, with later revisions focusing on attribution fixes.
• Row count is unknown, which may limit suitability assessment.
