Hydrogeological Landscapes of the Central West Local Land Services Region: Nov 2020 (First Edition) |
Alternative title(s) |
Central West LLS HGL - 2020 |
Abstract |
This dataset supersedes much of the area covered by previous CW CMA and Western CW catchment HGL assessments. It is bounded by the Central West LLS regional boundary rather than the old CW CMA boundary. For CW CMA areas that fall outside the CW LLS boundary, please refer to the Residual Hydrogeological Landscapes of the Central West CMA Catchment: Nov 2020 dataset. The Hydrogeological Landscape (HGL) concept provides a structure for the understanding of how salinity manifests itself in the landscape and how differences in salinity are expressed across the landscape. A HGL spatially defines areas of similar salt stores and pathways for salt mobilisation. The process of HGL determination relies on the integration of a number of factors: geology, soils, slope, regolith depth, and climate; an understanding of the differences in salinity development; and the impacts (land salinity/salt load/water electrical conductivity) in landscapes. Information sources such as soils maps, site characterisation, salinity site mapping, hydrogeological conditions and surface and groundwater data are combined to develop standard templates for each HGL. The focus of this dataset is the Central West LLS region. It comprises introductory information on HGLs; HGL unit descriptions; digital maps and spatial data. Spatial resolution for this product is 1:250 000. |

Purpose |
This data package was generated for Central West Local Land Services (CW LLS) to modify and extend existing HGL unit boundaries to the new CW LLS regional footprint. Unit descriptions were revised accordingly. |

Lineage |
The hydrogeological landscape (HGL) mapping used the following base data for delineation of map units: Existing HGL mapping data for the Central West catchment (polygon); published 1:1 million and 1:250 000 geological mapping data (polygon); published 1:250 000 soil landscape data (polygon); soil profile data from the SALIS database (point); and a Digital Elevation Model (DEM) for the Central West LLS region. |

DQ Topological Consistency |
|
Effective date |
2024-06-28 |
Explanation |
All polygons in the coverage are topologically correct and all polygons have been attributed. Data has been visually checked at applicable scales. |
DQ Absolute External Positional Accuracy |
|
Effective date |
2024-06-28 |
Explanation |
The accuracy of the coverage varies across the mapping area as map polygon boundaries were derived from different sources. HGL boundaries derived from published and draft 1:100 000 scale mapping are generally accurate to 100 m. HGL boundaries derived from published 1:250 000 scale mapping are approximate and generally accurate to 250 m. |
DQ Non Quantitative Attribute Correctness |
|
Effective date |
2024-06-28 |
Explanation |
All polygons are labelled with a hydrogeological landscape unit tag, and attributed with information relevant to salinity management. Attributes were checked as part of routine GIS capture quality assurance procedures, including a visual check of polygon tags against field data. |
