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] - Soil and Land Resources of the Liverpool Plains Catchment [1:100,000 scale] - Reconnaissance Soil and Land Resources of the Murray CMA Catchment [1:100,000 & 1:250,000 scale] - Soil Landscapes of the SCA Hydrological Catchments [1:100,000 scale] - Soils landscapes of the Comprehensive Coastal Assessment (Bare Point, Jervis Bay, Batemans Bay and Ulladulla) [1:100,000 scale] - Southern Comprehensive Regional Assessment [1:100,000 scale] - Northern Comprehensive Regional Assessment [1:100,000 scale] - Reconnaissance soil landscapes of the Namoi CMA [1:100,000 scale] - Reconnaissance soil landscapes of the Upper Riverina (HSHL) [1:100,000 scale] - Reconnaissance soil landscapes of the Border Rivers/Gwydir CMA [1:100,000 scale] - Brigalow Belt South Western Regional Assessment [1:100,000 scale] - Reconnaissance Soil Landscapes of the Upper Macleay Catchment [1:100,000 scale] - Upper Murrumbidgee Soil Benchmarking project [1:100,000 scale] - Glen Innes Data Gap Reconnaissance Soils Mapping [1:100,000 scale] - Soil Information for the Nyngan 1:250,000 sheet [1:250,000 scale] - Soil Information for the Walgett 1:250,000 sheet [1:250,000 scale] - Soil Information for the Gilgandra 1:250,000 sheet [1:250,000 scale] - Reconnaissance soil landscapes of the Riverine Plains [1:500,000 scale] - Land Systems of the Western Division [1:250,000-1:500,000 scale] - Land Systems of the Cobar Peniplain Bioregion [1:250,000-1:500,000 scale]

Each polygon was assigned a dominant soil type (Great Soil Group), from which a fertility value was derived using a lookup table modified from Charman (1978) (See Table 1). It is known that other soil types will exist in most if not all polygons, thus the map provides a guide to the most likely fertility of the soil.

Assumptions made in the allocation of soil fertility mapping include: 1. The dominant soil type allocated to each polygon is representative of that area. 2. The dominant soil type has the typical characteristics/properties of soils classified under the Great Soil Group classification.

Explanation

All polygons were labelled with a soil fertility class as per the classification.

A limited, targeted internal desktop review has been completed for the soil type (Great Soil Group) field used in the production of this map. In addition a more thorough desktop triage quality check has been completed for soil type (Great Soil Group) field covered within the New England/North West, Upper Hunter, Central West, Greater Southern Highlands and Sydney Canberra Corridor Strategic Regional Land use Priority areas.

Explanation

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

Explanation

The accuracy of this map 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 OEH 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. Other small scale datasets (e.g., datasets up to 1:500,000) are approximate and generally accurate to within 500 – 2,000 m.

Explanation

The accuracy of the attributes used to derive this map varies across NSW, as map polygon boundaries were derived from many different sources and map scales. A data source diagram (Figure 1) shows these different datasets and their quality according to the soils confidence classification outlined below:

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

Fair (2) - Most soil and landscape data is available at a catchment scale (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 the state scale (1:250,000 - 1:500,000) and the LSC and other soil thematic maps should be used as a guide only.
