What are tiers?
Tier 1
Estimate using own judgement and observations
For example, estimate % of total land area with each soil type, multiplied by total land area.
Tier 2
Estimate using third-party professional estimates or public data
Tier 3
Model or measure based on site-specific surveys/sampling, remote or in-field sensing, laboratory analysis, etc.
Example data sources
Internal records
Third-party data sources
Maps of Australian soil types are available at the Australian National Soil Information System (ANSIS) Data Portal.
Site-specific measurements or model outputs
Data on area of soil resources by soil type for New South Wales are available on request at the Central Resource for Sharing and Enabling Environmental Data in NSW (SEED) – Experimental Environmental-Economic Accounts for NSW – Soil Accounts – 2021.
Notes
For Tier 1 it would be appropriate to use whatever local soil classification the user is familiar with, and for Tier 3, whatever soil classification is used by third-party soil information providers. For Tier 2, it would be appropriate to use a nationally accepted soil classification standard such as Soil Science Australia’s standards for soil types or the 28 major groupings used in the FAO’s Harmonized World Soil Database. Note that volume (in cubic metres) of soil resources by soil type could also be recorded – however, reliable data is unlikely to be widely available.
