CORVEG mappings to Yellow Book

CORVEG contains categorical values such as growth form, structural formation classes, landform element, etc that map fully or partially to the Australian Soil and Land Survey Field Handbook.

CORVEG mappable categorical values


Landform situation

Definition: The HERBRECS code used to describe landform.

Doesn’t look like a straight-forward mapping to the handbook.

Landform element

Definition: The three-letter code taken from Speight (2009), such as cliff, crest, bank etc. and listed in Table 26 at the end of this appendix. Landform elements are in the order of 40 metres wide (Speight 2009).

See the landform element key and glossary page 31 to 44. Looks like most, if not all terms are there. Definitions look the same as well.

Erosional pattern

Definition: Two-letter code taken from Speight (2009, table 5) and listed in Table 24.

Erosional pattern is a combination of local relief (hill, plain) and slope class (flat, undulating, steep). The slope class may not be the same as the slope recorded for the site (for example, a site situated on a hill crest landform element of a steep mountain landform pattern).

See page 47, table 5. The table looks almost identical.

Landform pattern

Definition: A three-letter code taken from Speight (2009), such as floodplain, hill etc., and listed in Table 25 at the end of this appendix. Landform pattern can be derived from erosional pattern with the aid of tables 6 and 7 in Walker and Hopkins (1990). Landform (and erosional) patterns are in the order of 600 metres wide (Speight 2009).

See page 58 to 72.

Type (Morphological type)

Definition: Morphological type is broadly classified into types from Speight (2009) from the codes in Table 13.

See page 19 to 20.



Definition: Recorded as one of the following values; map, cutting, core or surface observation.

Not sure if it is the same as the type of soil observation on page 147.


Definition: The default value is L (low) but can be one of the following: H high—by a pedologist (or specialist) M medium—experienced non-pedologist or obvious

Not sure if this is available in the handbook.

Broad soil types

Definition: Broad soil types derived from HERBRECS code from the Corveg soil type and geological codes the categories in the tables aim to provide options for non-experts to recognise a broad category of soil and geology, while an expert soil scientist or geologist will be able to classify the soil or geology
to a more precise level. CORVEG allows the entry of the soil or geological code provided on soil/ geological coverages and these should be added to the database. The nomenclature of the Australian Soil Classification (Isbell et al. 2016) has been applied to the soil codes used in Table 20. This classification should be used for all newly collected soils site data.

Doesn’t look like this is available in the handbook.


Definition: Broad surface soil colour classes from Table 19.

CORVEG does not record if the soil is wet or dry, but it is mostly dry. It is based on the Revised Standard Soil Colour Charts from page 161 of the handbook with a few extra terms.


Definition: Broad soil surface texture from Table 19.

Not a direct mapping. See page 164 to 166.



Definition: Recorded as map, cutting, core or outcrop (or any surface) observation

Not sure if this is covered. Maybe will be something in the Land Surface chapter.
