Dominant landform, soils and vegetation are described for each Land Unit, and general land capability is assessed. The assessment is considered for Mapping the Future project for the Western Davenport Water Allocation District.Data supplied by this Department is licensed under the Creative Commons Attribution 3.0 Australia License (CC BY 3.0).

Survey methodologies and related technical assessments used during the investigation are listed in the accompanying technical report: Mapped land units typically exhibit a uniform pattern on aerial photography or satellite imagery, and present as a repeatable and recognisable combination of landscape terrain, soil type and associated vegetation community. While some degree of variation is normally expected within a land unit, such variation is usually too small or too inconsistent to map separately at the given survey scale. Attributes assigned according to the dominant feature. For example, where ten sites have been grouped to describe a particular map unit and two different soils described from these sites then the dominant soil is chosen. The department's list of core attribute values, described in the Data Dictionary below, have been added to each polygon. Each land unit has also been assessed for GENERAL LAND CAPABILITY, evaluating landscape characteristics that could influence the general use of the land. A General Land Capability Class of 1 Land with negligible constraints to Class 4 Land with Extreme Constraints has been assigned to each land unit. Descriptions for key characteristics considered important have been added to the land unit polygon, including flooding, slope (as a surrogate for water erosion), soil depth, soil drainage, surface rock, and wind erosion.
