This digital soil landscape product contains natural resource mapping for the Australian Capital Territory. The project was completed by the Office of Environment and Heritage (NSW). The project was funded by the ACT Government to enhance knowledge of soils, landscapes and physical constraints to land use in the urban and rural environment. The information will assist in informed decision making, planning and environmental modelling throughout the catchment.55 soil landscape map units have been described for the ACT. Each unit is an inventory of soil and landscape information with relatively uniform land management requirements, allowing major soil and landscape qualities and constraints to be identified.The GIS product shown here provides location of each of the soil landscape map units - including the soil landscape code and name. For more detailed information please see the full soil landscape reports for each unit, as well as the final report (seedatasets.seed.nsw.gov.au). Detailed spreadsheets can be used to join more detailed information to the GIS also available on request.Lineage:The mapping undertaken by the NSW Government was created using:existing published soil landscape mapping (Canberra and Michelago 1:100,000 map sheets);new soil landscape mapping (part Brindabella and Tantangara 1:100,000 map sheets).For all datasets, provisional soil landscapes were established firstly on the dominant geomorphic processes responsible for the formation of the landscape and secondly on the geological parent material. Elevation, aspect, vegetation patterns and human disturbance were other factors considered when defining units.For existing mapping, the boundaries of these provisional soil landscapes were mapped using stereoscopic interpretation of 1:40,000 scale black and white and 1:25,000 scale colour aerial photographs (Canberra) and 1:40,000 scale black and white aerial photographs only for Michelago. LANDSAT thematic mapper and radiometric imagery were used to assist with perception and charting of provisional soil landscapes. These boundaries were transferred onto 1:25 000 topographic base maps. After field checking boundaries and detailed investigations of the soil, the provisional landscapes were confirmed, amalgamated or sub-divided.For new mapping on the Brindabella and Tantangara sheets, the boundaries were captured by digitizing directly to screen at around 1:10,000 scale using ArcGIS. Ultra-high resolution (10 cm) aerial photographic imagery provided a base layer during the capture process. In addition the following data were used to assist delineate soil landscapes boundaries: ADS digital aerial imagery, radiometric imagery, SPOT 5 satellite imagery, climate data, 1 second DSM and DEM elevation data from the Shuttle Radar Topographic Mission (SRTM), 1:100,000 scale geological mapping, 1:25,000 topographic maps and DTDB digital terrain models.Soils have been examined and described in detail at over 500 sites in the ACT. This includes 79 new detailed sites to fill data gaps for this project. At each site, soil morphological data and site information were recorded on Soil and Land Information System (SALIS) cards or digitally collected via the eDIRT field data collection system. Sufficient field work was undertaken within each soil landscape to identify the range of soils present and to enable their distribution within the landscape to be described. To best knowledge none of the sites were randomly sampled. Sample intervals were selected to be morphologically representative examples of each soil material present in each type profile i.e. soil horizons.A comprehensive suite of soil tests have been analysed for many of the representative type soil profiles within the ACT.A desktop review of published soil landscape units has occurred resulting in some minor amendments to the existing linework.Positional Accuracy:Observations and soil profiles were located using handheld GPS or using 1:25,000 topographic maps.

We acknowledge the Traditional Custodians of the ACT, the Ngunnawal people. We recognise the special relationship and connection that Ngunnawal people have with this Country. Ngunnawal people are a thriving community whose life and culture are intrinsically connected to this land in a way that is core to their physical and spiritual wellbeing, their cultural practices, law/lore, songlines and stories. Ngunnawal people have maintained a tangible and intangible cultural, social, environmental, spiritual and economic connection to these lands and waters for thousands of years. This Story Map documents monitoring and research of the Murrumbidgee Fish Community in the ACT in 2021.

The ACT Boundary is a single region defined for land administration and the legal description of the Australian Capital Territory. The ACT boundary is defined in metes and bounds in the in the Districts Act 1966, and cannot be changed without changes to the legislation. The ACT Border was first defined by surveyors between 1910 and 1915, it was redefined by surveyors again between 2003 and 2008. The original border is defined by metes and bounds description in the Seat of Governance ACT 1909, the current ACT Border definition is shown on survey plans held at the ACT Environment, Planning and Sustainable Delivery Directorate. The ACT Boundary is 306 kilometers, covering an area of 2,358 kilometers squared. The ACT is bounded by the Goulburn-Cooma railway line in the east, the watershed of Naas Creek in the south, the watershed of the Cotter River in the west.Coordinate System is MGA2020-55 (EPSG #7855).
