Name: ACT Hydrogeological Management Areas (HGL)
Display Field: hgl
Type: Feature Layer
Geometry Type: esriGeometryPolygon
Description: The focus of this dataset is the Australian Capital Territory (ACT). 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.
Updates: By mid-2017, this dataset will be updated to align HGL boundaries with the final ACT Soil Landscape linework. After that, the dataset will be static, but could be updated as required if new or better mapping becomes available.
Fit for purpose: This dataset was captured at 1:25,000 scale. This dataset is fit for use as a tool for assessing land management issues at the paddock-scale in the ACT, but this does not negate the need for site assessment at a scale suitable to any potential land use or development under consideration. The mapping was mapped in GDA1994 MGA Zone 55s and transformed to GDA2020 MGA Zone 55s.
