Title

Management Areas for the HGL of the Australian Capital Territory 2017 (Third Edition)

Alternative title(s)

ACT_ManAreas_2017

Abstract

This dataset supersedes all earlier versions of 'Management Areas 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. The dataset defines individual management areas in defined Hydrogeological Landscapes (HGL), specifies landform elements and assigns a unique Landscape Code to be used when incorporating soil and land degradation management action information. The dataset provides the base for joining other landscape information to specific management areas when developing new spatial products for the ACT.

The management areas for the ACT were derived by:
(i) Dividing the ACT region into two regions – highlands and lowlands
(ii) Running LF7 with a 10 m DEM using these regions as a constraint
(iii) Combining the two outputs and intersecting with ACT HGL boundaries
(iv) Assigning a HGL management area to each of the LF7 classes in each HGL unit based on ACT HGL descriptions and field observation
(v) Converted to a feature class and dissolved
(vi) Extra information about each management area added to the feature class.

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). The 10 m DEM was a product of the Digital Terrain Models created from existing 10 m and 20 m contours sourced from the NSW Topographic Map Archive.

dataset

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 unique landscape management code and information about which HGL and landscape element they represent. 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.
