Title

Soil Data Confidence map for NSW

Abstract

This map provides a guide to the data confidence of DPIE's soil related thematic map products in NSW. Examples of products this map supports includes Land and Soil Capability mapping, Inherent fertility of soils in NSW and Great Soil Group soil types in NSW.

Confidence classes are determined based on the data scale, type of mapping and information collected, accuracy of the attributes and quality assurance on the product.

Soil data confidence is described using a 4 class system between high and very low as outlined below.:

  • Good (1) - All necessary 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.

  • 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 - 1:500,000) and the LSC and other soil thematic maps should be used as a guide only.

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.

Version changes

The major change in version 4 occurs in the Hunter Region with the inclusion of high quality 1:100,000 for the area into the thematic soil map products. The confidence in this area has been increased to high.

Lineage

The best available soils datasets were sourced to provide a single (seamless where possible) layer across the area. Datasets collated to derive this map included:

  • published and draft 1:100,000 soil landscape mapping [1:100,000 scale]

  • published and draft 1:250,000 soil landscape mapping [1:250,000 scale]

  • Soil and Land Resources of the Hawkesbury Nepean Catchment [1:100,000 scale]

Polygons for each soil dataset in NSW were dissolved to create one polygon per mapping dataset. These individual dataset polygons were then assigned a data confidence based on data scale, type of mapping and information collected, accuracy of the attributes and quality assurance on the product. Figure one in the data package shows a map of the final product.

DQ Completeness Commission

Explanation

All polygons were labelled with a data confidence class as per the classification. This map product was produced to support DPIE's soil thematic maps.

DQ Conceptual Consistency

DQ Topological Consistency

Effective date

2017-05-05

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

2017-05-05

Explanation

The mapping line work reflects the boundaries of many different soil datasets across NSW. These dataset boundaries were captured at different scales and reflect a mix of map grid boundaries (e.g. 1:100,000 maps sheets), water catchments, Catchment Management Authority regional boundaries and other statutory boundaries. The general accuracy of these boundaries range between 100-250 m.

DQ Non Quantitative Attribute Correctness

Effective date

2020-10-27

Explanation

Polygons were attributed with a class using the dataset’s overall soil mapping standard and the scale of map production. Considering the methodology used, the attribute accuracy is good for use at a catchment scale.
