Alternative title(s)

Gully and Streambank Erosion - Multi attribute mapping

Abstract

This digital product identifies linear based erosion features in central and eastern NSW and forms a component of a much larger natural resource dataset called multi attribute mapping.

Four severity levels of gully erosion plus streambank erosion and erosion of farm tracks are delineated in this mapping. Additional properties such as gully depth or presence of salting further subdivide these classes.

Descriptions of the 25 classes are documented in the Standard Classification for Attributes of Land (SCALD) manual.

Overall multi attribute data is a vector-based inventory of the landscape comprising polygon and linear features. This system of mapping describes a number of attributes (such as slope, terrain, land use, vegetation community, presence of tree regrowth, soil erosion, rock outcrops, weed species and soil conservation measures) into one polygon. The value of attribute mapping lies in the fact that the data, which objectively characterises the land, can be used for a variety of purposes. This translates into the availability of a range of derivative maps.

Mapping is typically carried out at 1:25 000 scale using topographic maps as a base. Outputs are most useful at the sub-catchment or regional scale but not generally at the property level.

Lineage

Multi attribute mapping has developed from erosion/land use mapping carried out by DLWC and precursor organisations. Linework is based on aerial photograph interpretation (photo's dated between 1991 - 1993) by staff with training in natural resource assessment. Polygons are attributed with a selected suite of attributes, comprising: slope; landform; land use; vegetation type; tree regrowth; weed species, soil erosion; mass movement; rock outcrop; and soil conservation measures. Linear features indicate particular erosion features such as gullies and streambank erosion. These attributes are a subset of a more extensive set of attributes belonging to the Standard Classification for Attributes of Land (SCALD).Metadata imported.C:\Program Files\ArcGIS\Metadata\ANZMeta\Thesaurus\temp.xml2008090215222900

DQ Completeness Commission

Effective date

2009-01-10

Explanation

Mapping was carried out on 1:25 000 scale topographic maps from 1:25 000 scale aerial photography. Linear features less than 100 m in length were not represented. No minimum exclusion or inclusion area was set due to the nature of the mapping. ; ; Map legends are compact and standardised, carrying only limited descriptive information. Users of the data are urged to consult the Standard Classification for Attributes of Land (SCALD) for a full listing of the categories used and Landscape Assessment Unit staff for assistance with interpretation of the data.

DQ Conceptual Consistency

Effective date

1900-01-01

Explanation

Logical consistency checks performed, included label errors, overshoots, undershoots, polygon closures and topology. These tests ensure that all classified polygons are closed, nodes are formed at the intersection of lines and that there is only one label within each polygon,etc.

DQ Absolute External Positional Accuracy

Effective date

1900-01-01

Explanation

The estimated positional accuracy of the linework is between 12.5 m and up to 75 m, dependent upon the intensity of pre existing locational reference data (such as contours, cadastre, etc).

DQ Non Quantitative Attribute Correctness

Effective date

1900-01-01

Explanation

Land characteristics are interpreted from aerial photography by experienced Landscape Assessment Unit staff using the Standard Classification for Attributes of Land (SCALD), DLWC's standardised set of attribute codes. SCALD definitions are based on Australian Standards where applicable or DLWC standards elsewhere. Field verification was carried out to check and correct identification. ; ; Standard DLWC edge matching procedures were carried out on all tile joins for all attributes.
