Description
This spatial dataset, surveyed at a scale of 1:25 000, provides polygon information on the vegetation community boundaries of Bullo River Station, Northern Territory. The main purpose of the survey is vegetation community mapping and floristic inventory.
Soil-landscape information was also mapped and described, however, this broadscale information is relevant at a scale of 1:100 000; and may be referred to by this department as landunit dataset BULLO_100. (Please note; BULLO_100 does not exist as a specific land resource dataset. Refer to this vegetation dataset BULLO_25 for spatial data)
Bullo River Station covers an area of 1627 km2 and is located approximately 800 km south-west of Darwin and 460 km west of Katherine by road.

Data Quality
Lineage:Vegetation community 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.
Vegetation community polygons collected via geographic information system (ARCGIS). Core vegetation, landform and soil and attributes attached to vegetation communities with additional attributes unique to individual surveys.
Positional Accuracy:Vegetation community boundaries digitised on screen directly from digital rectified aerial photographs. 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 high to very high.
Attribute Accuracy:Attributes assigned according to the dominant feature. For example where ten sites have been grouped to describe a particular vegetation community and two different communities are described from these sites then the dominant community is chosen
Logical Consistency:GIS editing tools were used to rectify all overshoots and undershoots in linework. Using ArcInfo topographical consistency checks were performed to detect flaws in the spatial data structure. The coverage was cleaned, to eliminate any duplicates arcs. The coverage was built for arcs and polygon topologies. A label errors routine was run to detect unlabelled polygons. A node errors routine was run to identify pseudo nodes and dangles. Checks were done to unsure that all classified polygons are closed, nodes are formed at intersections of lines and that each polygon has only one label.
Completeness:Complete.
