Mapped information describes vegetation units and their attributes and provides a basis for identifying the extent and distribution of vegetation resources for the Arafura Swamp area. The survey area of 900 km2 is located on the northern coast of Arnhem Land, from Castlereagh Bay south east of Millingimbi Island and includes the coastal plains region. The original field surveys were conducted in May 1990 at a mapping scale of 1:50,000.Download the spatial data package (contains spatial data, maps and reports) via https://data.nt.gov.au/ You are licensed to use the 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.

Note that species names may have changed since this report was published.0not knownDataset topological consistency has been checked and all classified polygons are closed, nodes are formed at the intersection of lines and there is only one label within each polygon. Polygons have been classified for Veg community ID in the lookup table.0not knownDerived from topographic basemap and NT cadastre. The summation of errors from all sources results in data with a standard deviation defined by scale used as +/-100m 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. The spatial dataset has been compiled with a standard set of attributes used by the department. The attributes for this dataset only include NVIS Levels 1, 2 and 3. Notes have been added to the Data Dictionary in this record where the attributes have not been included.0Original linework derived using aerial photography to delineate mapping unit boundaries and site selection, then extensively ground-truthed with topographic basemap/GPS coordinated field survey and site data collection. Resultant verified linework georeferenced to 1:50,000 topographic basemap then input into GIS system as ArcInfo vector information and built as a polygon cover. Source data: Aerial photography - 1:50,000 Col; Base map - Australian Topographic Survey Series 1:50,000 AGD66; Northern Territory Cadastre AGD66; GIS - ArcInfo vector as AGD66/GDA94 February 2022: The spatial data was recompiled and projected to datum GDA94 to an ESRI file geodatabase using a standard set of attributes defined by this department.
