NV2005_EXTENT: Modelled Native Vegetation Extent 2005

July 15th, 2007 marks the completion of this modelled dataset depicting native vegetation and aquatic habitat extent for 2005. Created by the Arthur Rylah Institute, it categorizes landscapes into eight likelihood categories ranging from 'highly likely native vegetation' to 'unlikely to support native vegetation'. The model integrates Landsat imagery from 1989-2005, ground-truthing points, and expert validation.

Use Cases

• Model land cover change over time based on the 1989-2005 Landsat imagery time-series
• Assess habitat conservation priorities based on the eight native vegetation likelihood categories
• Validate other land-use datasets using the expert validation and ground-truthing points mentioned

Strengths

• Integrates Landsat imagery from a 16-year time-series (1989-2005)
• Includes many thousands of ground-truthing points for validation
• Categorizes landscape into eight distinct native vegetation likelihood classes

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
• The dataset is modelled, requiring careful use as noted in the description
