ASDST Grinding Grooves Current Model: Predictive Likelihood for NSW

A 2020 geospatial model predicts the likelihood of Aboriginal grinding grooves across New South Wales. The Department of Planning, Industry and Environment produced this raster layer at 50-meter resolution using a Geographic Coordinate System. It is part of the Aboriginal Sites Decision Support Tool suite, which includes separate models for other site types like rock art and stone artefacts.

Use Cases

• Assess landscape development impacts based on predicted likelihood of cultural heritage features.
• Prioritize field survey areas based on the model's reliability layer mentioned in the description.
• Compare pre-colonisation and current feature likelihood to understand accumulated impacts.
• Support planning decisions for Aboriginal heritage sites based on predictive raster outputs.

Strengths

• Model covers the entire state of New South Wales.
• Provides a current landscape prediction at 50-meter resolution.
• Cell values are on a defined 0-1000 likelihood scale.
• Part of a larger suite of models for different Aboriginal site feature types.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
