ACT Land and Soil Capability with Salinity Hazard Ratings

A 1:25,000 scale geospatial dataset for the Australian Capital Territory (ACT) developed by Rob Muller, Wayne Cook, Allan Nicholson, and Alie Cowood. It contains hazard ratings for land salinity, stream salt load, and stream EC, as well as landscape function information and management strategies for each Hydrogeological Landscape (HGL) unit. The dataset is fit for use as a tool for assessing land management issues at the paddock-scale in the ACT.

Use Cases

• Assessing land salinity hazard for paddock-scale management based on hazard ratings.
• Planning salinity management strategies based on landscape function information.
• Analyzing spatial patterns of salt mobilization based on Hydrogeological Landscape (HGL) unit delineations.
• Integrating causative factors like geology, soils, and slope for environmental modeling.

Strengths

• Captured at a 1:25,000 scale, suitable for paddock-scale assessment.
• Integrates multiple information sources including soil landscape maps, hydrogeological data, and salinity occurrence maps.
• Provides hyperlinks to full management descriptions for each Hydrogeological Landscape (HGL) unit.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The ACT Government disclaimer states the map may not be free from error.
• Row count is unknown, which may limit suitability assessment.
