ASDST All Combined Features Pre1750 Model

New South Wales is covered by a raster GIS model predicting the likelihood of Aboriginal site features prior to European colonization. The dataset includes separate layers for specific feature types like stone artefacts and rock art, with cell values ranging from 0 to 1000. It was produced by the NSW Department of Planning, Industry and Environment in 2020 at 50-meter resolution.

Use Cases

• Assess landscape planning risk based on predicted likelihood of Aboriginal site features.
• Compare pre-colonization and current landscape likelihoods for impact analysis.
• Prioritize survey areas based on model reliability and data gaps mentioned in the description.

Strengths

• Covers the entire extent of New South Wales.
• Provides separate predictive layers for 9 distinct Aboriginal site feature types.
• Offers both pre-colonization and current landscape model forms.

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.
