Data Quality
Lineage:Original map unit boundaries delineated from aerial photographs and stereoscopic interpretation. Map units transferred to clean dyeline sheets or topographic maps via a mapograph. Original maps were hardcopy only. Field data (site data) described and classified according to national standards at the time of capture (1982) and original map unit descriptions derived from this data.
With the advent of geographic information systems (GIS) polygons were captured by scanning and rectifying the original hard copy maps. The location of the map unit boundaries were adjusted in a GIS using georeferenced colour aerial photographs captured in 2004 and other data.
Attribution of map unit polygons incorporates the original map unit and, based on current national standards (2009), core landform, soil and vegetation descriptions attached to map units with additional attributes unique to individual surveys.
Positional Accuracy:POLYGON DATA
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. With the advent of geographic information systems (GIS) polygons were captured by scanning and rectifying the original hard copy maps. The location of the map unit boundaries were adjusted in a GIS using georeferenced colour aerial photographs captured in 2004 and other data.
Positional accuracy generally considered moderate to 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.
Attribution of map unit polygons incorporates the original map unit label (M3a) and, based on current national standards (2009), core landform, soil and vegetation descriptions attached to map units with additional attributes unique to individual surveys.
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:Review in progress.
