Bioregional_Assessment_Programme_GIP - Catchment Scale Land Use of Australia 2014 for the Gippsland Basin bioregion

Abstract

This dataset was derived by the Bioregional Assessment Programme from the Catchment Scale Land Use of Australia - 2014 dataset (GUID: 6f72f73c-8a61-4ae9-b8b5-3f67ec918826). 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.

This dataset includes:

1. A clip of the dataset 'Catchment Scale Land Use of Australia - 2014' to the Gippsland Basin bioregion boundary

2. Two tables showing land use statistics for the Gippsland Basin bioregion (primary and secondary land use classification)

Dataset History

The Catchment Scale Land Use of Australia - 2014 (https://data.bioregionalassessments.gov.au/datastore/dataset/6f72f73c-8a61-4ae9-b8b5-3f67ec918826) was clipped by the Gippsland Basin bioregion project boundary (https://data.bioregionalassessments.gov.au/dataset/e8a2d577-c5c5-4e2c-b0fa-53e4b2d4a034) in ArcMap using 'Extract by Mask'.

Statistics for each land use type were derived from the clipped dataset by:

1. Using the 'Summary Statistics (Analysis)' tool in ArcMap with the follwing inputs: Statistics Field = 'COUNT', Statistic Type = SUM. The tool was run twice, once for the Primary classification and once for Secondary, producing two output tables.

2. In each table a new field 'AREA_SQ_KM' was added and the area calculated in the Field Calculator using the following equation [SUM_COUNT]*0.0025 (because the SUM_COUNT field indicates the number of 50mx50m grid cells).

3. The percentage of total Gippsland Basin Bioregion area covered by each land use type was then calculated in a new field (AREA_PERC) using ([AREA_SQ_KM]/14607.81)*100 in the field calculator.
