Title

Australian Soil Classification (ASC) soil type map of NSW

Abstract

This map identifies the dominant soil types across NSW using the Australian Soils Classification (ASC) at Order level. It uses the best available soil resource mapping coverage incorporating over 55 different datasets of multiple scales across NSW.

The formal ASC classification has been slightly modified in this map to further identify 2 extra sub-classes - soils with alluvial origins in the Rudosol order and soils with sodium-rich subsoils in the Kurosol order category.

Soil types are representative of the dominant facet (sub-landscape) of each map unit and allocated using a lookup table system, linking a Great Soil Group classification soil type to the most appropriate Australian Soil Classification (ASC) class (see LUT table in data package). In some areas (north coast region and Cobargo area), an ASC classification has been assigned to map units directly without using a lookup system. These areas are identified in the ASC confidence map found within in the data package. While the ASC classification commonly equates to a particular GSG soil type classification, this is is not always the case and therefore ASC classifications allocated manually, will have a higher accuracy.

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.

Each map unit polygon was assigned a dominant soil type (Great Soil Group classification), from which an Australian Soil Classification value (Isbell 1996) was derived using a lookup table (see Table 1 in data package). It is known that the link between the two classifications does not always have a one to one relationship so the most common ASC class was selected. For example Red Brown Earths (GSG) are most commonly classified as a Chromosol (ASC) but may sometimes occur as a Sodosol (ASC). It is also likely that multiple soil types will exist in most if not all polygons. Thus the map gives only a guide to the most likely soil types present.

In some areas (north coast region and Cobargo area), an ASC classification was assigned to each map unit directly without using a lookup system. These areas are identified in the ASC confidence map found within in the data package. While the ASC classification commonly equates to a particular GSG soil type classification, this is is not always the case and therefore ASC classifications allocated manually, will have a higher accuracy.

The ASC classifications used in this map have been slightly modified from the published classification to provide 2 additional classes. Rudosols have been split to identify Rudosols derived from alluvial process (Rudosols - alluvial) and the Kurosol class has been split to include an additional class identifying this sodic/natric subsoil property (Kurosols - natric).

DQ Completeness Commission

Effective date

2020-09-24

Explanation

All polygons were labelled with a soil type class as per the classification except for the following units below which have been labelled accordingly: Water = Water and rock and Disturbed Terrain = Not assessed.

An internal desktop review has been completed for the Great Soil Group soil type field, used in the production of this map along with limited checking of the ASC classification.

DQ Topological Consistency

Effective date

2020-09-24

Explanation

ArcGIS was used to ensure all polygons in the feature class are topologically correct. (cluster tolerance 0.000003 DDeg).

DQ Absolute External Positional Accuracy

Effective date

2020-09-24

Explanation

The accuracy of this map coverage varies across NSW, as map polygon boundaries were derived from many different sources and scales (see lineage). Soil boundaries using published and draft 1:100,000 scale mapping by DPIE are generally accurate to within 100 m. Soil boundaries using published or draft 1:250,000 scale, SCA and reconnaissance 1:100,000 - 1:250,000 level soil landscape mapping are generally accurate to within 250 m. Land Systems is a different style of mapping however is published at a scale of 1:250,000 and is generally accurate to within 250m. Some small alignment issues may occur for Land Systems mapping from issues with the digitizing process when first captured years ago into a digital format.

DQ Non Quantitative Attribute Correctness

Effective date

2020-09-24

Explanation

The accuracy of attributes used to derive this map coverage varies across NSW, as map polygon boundaries were derived from many different sources and map scales. A data source diagram (see figure one in data package) shows these different datasets and their quality according to the data confidence classification outlined below:

  • High (1) - All necessary soil and landscape data is available at a catchment scale (1:100,000) to undertake the assessment of LSC and other soil thematic maps.

  • Moderate (2) - Most soil and landscape data is available at a catchment scale (1:100,000 - 1:250,000) to undertake the assessment of LSC and other soil thematic maps.

  • Low (3) - Limited soil and landscape data is available at a reconnaissance catchment scale (1:100,000 & 1:250,000) which limits the quality of the assessment of LSC and other soil thematic maps.

  • Very low (4) - Very limited soil and landscape data is available at a broad catchment scale (1:250,000 or 1:500,000) and the LSC and other soil thematic maps should be used as a guide only.
