The survey area encompasses 164 km2 of the south-east portion of Kakadu National Park and is located approximately 225 km south-east of Darwin. The original field survey was undertaken in 1982 at a mapping scale of 1:50,000. Core attributes describing the land units, as defined by this department, were added to the spatial dataset in March of 2025Download the spatial data package (contains spatial data, maps and reports) 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.

Polygon topology rules applied are; must not overlap, must not have gaps and each polygon has only one label.0not knownPOLYGON DATA: Hardcopy maps rectified using control points marked on original hardcopy maps. Control points include creek lines, cadastre and other topographic features. Depending on the nature of the landscape (the number of control points) positional accuracy may vary. Positional accuracy generally considered moderate. POINT DATA: Survey teams navigated during field operations with topographic maps, aerial photographs and prismatic compass. Point source locations marked on aerial photography in the field. Positional accuracy considered within 300m but generally below 200m depending on the terrain. Site coordinates derived by transferring site locations from aerial photographs to topographic maps and coordinates calculated. In some cases, sites have been georeferenced directly from aerial photography to Google Earth Web Map Server in ArcGIS.0not knownThe attribute information conforms to the 'Australian Soil and Land Survey Field Handbook' at time of capture. 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 has assigned a list of core attribute values, described in the Data Dictionary below, to each polygon. The attribute naming format uses 10 characters with no spaces to be suitable for an ESRI shape-file format. An alias attribute name is applied to an ESRI file geo-database format.0Original map unit boundaries delineated from aerial photographs and stereoscope interpretation. Map units transferred to clean dyeline sheets via a mapograph. Original maps were hardcopy only. With the advent of geographic information systems polygons were digitised by georeferencing the original hard copy maps. Original map unit boundaries derived using hard copy aerial photography and stereoscope geological and topographic maps. Field data (site data) described and classified according to national standards at the time of capture. Map unit polygons collected via geographic information system (ESRI ArcGIS). Core landform, soil and vegetation attributes attached to map units with additional attributes unique to individual surveys.
