Data Quality

Lineage:Original map unit boundaries delineated from aerial photographs and stereoscope interpretation. Map units transferred to clean dyeline sheets or topographic maps 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 hard copy aerial photography and stereoscope, satellite imagery (post 1993), geological and topographic maps. Field data (site data) 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:Hardcopy maps rectified using control points marked on original hardcopy maps. 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.

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.

Completeness:Complete.
