Mapped information describes associated patterns/land systems as distinct from higher resolution mapping. Information is usually interpreted to indicate land capability for a range of land uses and provides a basis for identifying the extent and distribution of land resources for the Darwin Region. (Land System - An area or group of areas throughout which there is a re-recurring pattern of landform, soils and vegetation. Recognised as being an assemblage of Land Units). This spatial dataset was amalgamated within the compilation dataset Land System Surveys of the Northern Part of the Northern Territory. (Department survey code NORTH_250) Refer to Metadata record: http://www.ntlis.nt.gov.au/metadata/export_data?type=html&metadata_id=8E85C28F9C9285EBE040CD9B21447F57 Download the spatial data package (contains spatial data, maps and reports) via https://data.nt.gov.au/ You are licensed to use the DENR geospatial products on the terms and conditions set out in: Creative Commons Attribution 4.0 International Public License (CC BY 4.0) at: https://creativecommons.org/licenses/by/4.0/legalcode If you do not agree to the terms and conditions you must not use the geospatial products.

The summation of errors from all sources results in data with a standard deviation defined by scale used as +/-250m for well-defined points.0not knownThe accuracy of the attribute information is considered high and conforms to the 'Australian Soil and Land Survey Field Handbook' at time of capture.0Original linework derived stereographically using aerial photography to delineate land unit boundaries and site selection, then extensively ground-truthed with topographic basemap coordinated field survey and site data collection. Verified linework transferred photogrammatically to 1:100,000 film/base to produce final map. Resultant linework scanned/digitised into GIS system as ArcInfo vector information then built as a polygon coverage. Recompiled and updated to GDA94 as part of ongoing GIS Progarm 2004.
