The dataset was derived by the Bioregional Assessment Programme. This dataset was derived from multiple datasets. You can find a link to the parent datasets in the Lineage Field in this metadata statement. The History Field in this metadata statement describes how this dataset was derived.
A line shapefile of the Hunter subregion boundary with line segments attributed with the biophysical feature/dataset that defines that section of the boundary. This dataset is derived from the Bioregional Assessment areas and links to the source datasets are in the lineage field of this metadata statement.
To identify the underlying source used to define the boundary. Mostly the Bioregion boundary was used but some sections are defined by geology and CMA boundaries.For report map purposes.
A polygon shapefile of the Hunter subregion was converted to a line shapefile. The subregion boundary was then compared with the datasets that the subregion metadata listed as boundary sources (see lineage).
The subregion boundary line was split (ArcGIS Editor Split tool) into sections that coincided with the source boundary layers and attributed accordingly.
