BA All Regions BILO cells in subregions shapefile


The dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.

A polygon shapefile of BILO grid cells for each subregion in the Bioregional Assessment. These data should be used for mapping and indicative purposes only as cells are not mutually exclusive between some adjoining bioregions. See history for more details.

Cells are identified by their GRIDCODE, that being a nine digit integer derived from the centroid lat-long co-ordinates.

The formula is (long nnn.nn) x 100,000 + -(lat nn.nn) x 100

eg a cell with a centroid of 148.05 degrees east and -26.55 degrees south would have an ID of 148052555

Subregions are coded as follows:

No subregion

1 Gippsland

2 Wollongong Coast

3 Georges River

4 Hawkesbury-Nepean

5 Hunter

6 Gloucester

7 Clarence-Moreton

8 Central West

9 Namoi

10 Gwydir

11 Maranoa-Balonne-Condamine

12 Arckaringa

13 Pedirka

14 Galilee

14 Cooper

note: Cooper and Galilee both have code 14

Dataset History

The data were extracted from the BILO grid cells for the whole of Australia using an intersection of the BILO cells with the subregion boundaries in ArcGIS. The order of processing for each subregion polygon determined the coded assigned to each cell polygon such that where a cell intersect more than one subregion boundary (i.e. where subregions share a common boundary) then the boundary used in the most recent selection will over-ride that of previous selections. For individual subregions it is recommended that such selection is done individually for the single subregion polygon if these data are required for further analysis. This data set should only be used for over-view mapping and indicative purposes.
