Classified depth to water table for the Great Artesian Basin

Abstract

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.

Categorised depth to groundwater in the Great Artesian Basin.

Categories are: (Depth indicated is meters below surface, surface elevation taken from 3 Second SRTM DEM-s)

1 = 0 - 5m

2 = 5 - 10m

3 = 10 - 15m

4 = 15 - 20m

5 = 20 - 25m

6 = 25 - 30m

7 = 30 - 35m

8 = 35 - 40m

9 = +40m

Dataset History

Grid derived from subtracting the GAB waterlevel elevation surface from the GA 3second SRTM DEM-s

1. Depth to water table grid created using Raster Calculator. [GA 3sec SRTM DEM-s] - [GAB water table grid], Grid: float, produced.

2. QA/QC on float grid to remove values 40m. This final output is the available grid within this dataset.
