Soil and Land Degradation Management for the HGL of the Australian Capital Territory 2017 (2nd Ed) |

Abstract |
This dataset supersedes all earlier versions of 'Soil and Land Degradation Management for the HGL of the Australian Capital Territory'. It incorporates HGL boundary and management area edits based on updated soil landscape mapping for the ACT. The focus of this dataset is the Australian Capital Territory. It contains digital spatial data developed to assist in land management decision making in the ACT. The dataset identifies soil and land degradation issues in defined Hydrogeological Landscapes (HGL). At the HGL unit level, information about general management issues and landscape function is assigned. Classifications for Land and Soil Capability (LSC) Soil Regolith Stability and Soilworks class are assigned at an individual management area level within each HGL. Appropriate management actions for soil and land degradation management and specific high risk land uses are given for each management area. Hyperlinks to full soil and land degradation management descriptions for each HGL unit are provided. The Hydrogeological Landscape (HGL) concept provides a structure for understanding how differences in salinity are expressed across the landscape. A HGL spatially differentiates areas with similar salt stores and pathways for salt mobilisation. The process of delineating a HGL relies on the integration of a number of causative factors: geology, soils, slope, regolith thickness, and climate; an understanding of the different modes of salinity development; and the impacts of salinity within landscapes (land salinity, salt load and salt concentration in streams due to salt contributions from base flow and runoff ). Information sources such as soil landscape maps, site characterisation, salinity occurrence maps, hydrogeological data, surface water and groundwater data are incorporated into standardised unit descriptions. Spatial resolution for this product is 1: 25 000. |

Purpose |
This dataset was generated for the ACT Environment and Planning Directorate as a component of the ACT Hydrogeological Landscapes (HGL) Framework project. The focus of this project was to assess impacts of climate change on wetlands and on land degradation issues related to salinity and erosion in the ACT. |

Lineage |
The hydrogeological landscape (HGL) mapping used the following base data for delineation of map units: published 1:1 million, 1:250 000 and 1:100 000 geological mapping data (polygon); published 1:100 000 soil landscape data (polygon); soil profile data from the OEH SALIS database (point); and Digital Elevation Model (DEM) for the ACT and derivative products taken from the 30 and 10 metre DEM. |

DQ Topological Consistency |
|
Effective date |
2017-05-19 |
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 |
2017-05-19 |
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 |
2017-05-19 |
Explanation |
All polygons are labelled with a hydrogeological landscape unit and management area tags, and attributed with information relevant to soil and land degradation management. Attributes were checked as part of routine GIS capture quality assurance procedures, including a visual check of polygon tags against field data. During the fieldwork phase, regular meetings were held to discuss and review methods, processes and consistency in landscape interpretation and documentation. |
