Dominant landform, soils and vegetation communities are described for each Land Unit, and general land capability is assessed.Download the spatial data package (contains ESRI spatial data) via data.nt.gov.au/ You are licensed to use the DLPE geospatial products on the terms and conditions set out in: Creative Commons Attribution 4.0 International Public License (CC BY 4.0) at: creativecommons.org/licenses/by/4.0/legalcode If you do not agree to the terms and conditions you must not use the geospatial products.

Survey methodologies and related technical assessments used during the investigation are listed in the accompanying technical report: Burgess J, Burley P, Carnavas M and Petursson J (2024) Land Resources of the Katherine South Area, Northern Territory. Technical Report 32/2024, Department of Lands, Planning and Environment, Northern Territory Government, Darwin. 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, microrelief, salinity, slope (as a surrogate for water erosion), sodicity, soil depth, soil drainage and surface rock. Land units categorised as 'Disturbed' or 'Urban' have not undergone further subclassification, and consequently, contain null values in subsequent classification fields.0Map land unit boundaries delineated from interpretation of digital aerial photography (15cm) satellite imagery including ESRI World Imagery, Google Satellite Imagery, Sentinel-2 imagery, and an aerial-photo derived 2.5m Digital Terrain Model. Field data described and classified according to national standards at the time of capture. Final map unit boundaries adjusted to account for field data. Core landform, soil and vegetation attributes attached to map units with additional attributes unique to individual surveys. Spatial data formats are ESRI file geodatabase and shapefiles. Data is stored in datum GDA94, geographics.
