The mapped information describes vegetation units and their attributes as floristic and environmental data and provides a basis for identifying the extent and distribution of vegetation resources. The original field survey was undertaken in 1996 at a mapping scale of 1:50,000. The survey area of 1,151km2 is located approximately 90km east of Darwin on the coastal plains west of Kakadu National Park, between the coastline and the MacKinlay River just south of the Arnhem Highway.

Polygon topology rules applied are; must not overlap, must not have gaps and each polygon has only one label.0not knownPOLYGON DATA: Map unit boundaries transferred from aerial photographs to topographic maps, using the best available topographic mapping at the time (generally 1:100 000) via a mapograph. Level of accuracy depends on the number of control points on individual aerial photographs. 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 to high. POINT DATA: Site point coordinates collected from a geographic positioning system with general accuracy of within 100m. Selective availability during this time prevented increased accuracy. 0not knownAttributes assigned according to the dominant feature. The accuracy of the attribute information conforms to the 'Australian Soil and Land Survey Field Handbook' at time of capture. Analysis of site data to provide community information.0Original map unit boundaries delineated from aerial photographs and stereoscope interpretation. Map units transferred to topographic map sheets via a mapograph. Original maps were hardcopy only. With the advent of geographic information systems polygons were digitised by rectifying the original hard copy maps. Map unit boundaries derived using aerial photography and digital satellite imagery, geological and topographic data. Field data (site information) described and classified according to national standards at the time of capture. Map unit polygons collected via geographic information system (ArcGIS/MapInfo).
