Title

Soil Regolith Stability for North-East and South-East New South Wales

Abstract

The Soil Regolith Stability classification is used in the assessment of soil water erosion and water pollution hazards. It is currently in use as part of the EPA 1998/99 Pollution Control Licences within state forests. This map identifies soil regolith stability classes using linework and soil information from published soil landscape mapping and reconnaissance soil landscapes of Northern and Southern Comprehensive Regional Assessment (CRA) mapping projects.
Each soil landscape unit on the coverage has been allocated a regolith stability classification (soil erodibility), comprising of four classes:

  • class R1 – High coherence soils with low sediment delivery potential
  • class R2 – Low coherence soils (when wet) with low sediment delivery potential
  • class R3 – High coherence soils with high sediment delivery potential
  • class R4 – Low coherence soils (when wet)

A regolith stability classification consists of a dominant class and up to three sub-dominant classes (if necessary), for example, R1(R3,R4), where R1 is the dominant regolith stability class and (R3 & R4) are the sub-dominant regolith stability classes.

Online Maps: This dataset can be viewed using eSPADE (NSW’s soil spatial viewer), which contains a suite of soil and landscape information including soil profile data. Many of these datasets have hot-linked soil reports. An alternative viewer is the SEED Map; an ideal way to see what other natural resources datasets (e.g. vegetation) are available for this map area.

Lineage

The Soil Regolith stability map was compiled from the following data sources: * Published and draft 1:100 000 and 1:250 000 Soil Landscape Mapping * Reconnaissance Northern and Southern Comprehensive Regional Assessment (CRA) mapping. Some areas of this mapping were modified and re-tagged to improve the dataset. * Soil Landscape mapping for the Sydney Catchment Authority (SCA) Hydrological Catchments, * New linework in small areas with no existing soil landscape mapping.

New reconnaissance level soil landscape mapping was created using the following base data and methods: * existing published and pre-publication 1:100 000 soil landscape mapping nearby, - published geology data, * Soil profile data from the Soil and Land Information System database (SALIS), * radiometric imagery, * satellite imagery, such as Landsat TM. * very little or no field assessment was undertaken.

Regolith Assessment: A Microsoft Access database was used to record soil and landscape information important for the determination of regolith classes across the mapping area. For soil map units, a regolith class (R1-4) was assigned to each facet/sub-landscape and the dominant of these class identified for the overall soil landscape map unit. On the map, the regolith classification consists of a dominant class and up to three sub-dominant classes (if necessary). For example, R1(R3,R4), where R1 is the dominant regolith stability class and (R3 & R4) are the sub-dominant regolith stability classes.

Areas of rock outcrop, water bodies, disturbed terrain (e.g. quarries) were not assessed as part of the soil regolith mapping project. In addition a 201 km2 polygon within the mapping area was not assessed and has been identified as unmapped.

dataset

DQ Completeness Commission

Effective date

2002-07-05

Explanation

All polygons are labelled with a regolith class or equivalent code. One 201 km 2 polygon within the mapping area was not assessed and has been identified as unmapped. Soil regolith stability classes have been checked.

DQ Conceptual Consistency

Effective date

2002-07-05

Explanation

The regolith classification was applied in a consistent manner for all map units within the mapping area. There was always a minimum soil and landscape inventory available to make the assessment.

DQ Topological Consistency

Effective date

2002-07-05

Explanation

All polygons in the coverage are topologically correct and all polygons have been attributed.

DQ Absolute External Positional Accuracy

Effective date

2002-07-05

Explanation

The accuracy of the coverage varies across the mapping area of South-east and North-east New South Wales. This is because map polygon boundaries were derived from different sources. Soil boundaries using published and draft 1:100 000 scale mapping and from Sydney Catchment Authority catchment are generally accurate within 100m. Soil boundaries using published 1:250 000 scale, and updated reconnaissance level Northern and Southern CRA mapping are approximate and generally accurate to within 250m.CRA mapping has had limited quality checking and is more likely to contain errors.

DQ Non Quantitative Attribute Correctness

Effective date

2002-07-05

Explanation

Soil regolith stability classes using published and draft soil landscapes and new SCA 1:100 000 scale mapping are generally accurate to 1:100 000 soil landscape mapping standards. Soil attributes using published 1:250 000 scale are generally accurate to 1:250 000 soil landscape mapping standards. Soil attributes using CRA reconnaissance level soil landscape mapping are approximate and should be used only as a guide because CRA mapping was rapidly collected, has had limited quality checking and is more likely to contain errors. Assigned regolith classes have undergone some broad level quality assurance including checking by local experts around NSW.
