Description
High resolution survey describing/mapping landform, soils and
vegetation. Mapped information describes uniform areas/land units and their
attributes as distinct from reconnaissance level/land system surveys. Information
is generally interpreted to indicate land capability for a range of land uses. (Land
Unit - A reasonably homogeneous part of the land surface, distinct from surrounding
terrain, with constant properties in landform, soils or vegetation) - The survey area
is approximately 310km sq including Alice Springs and some of the surrounding area.

Data Quality
Lineage:Map unit boundaries delineated from aerial photographs. Aerial photography scanned and rectified. Linework digitised on screen directly from original aerial photographs.
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 (ARC/MapInfo). Core landform, soil and vegetation attributes attached to map units with additional attributes unique to individual surveys.
Positional Accuracy:1:25,000. Map unit 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 map unit and two different soils described from these sites then the dominant soil 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.
