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.
