Data Quality

Lineage:Original 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 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: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.

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.

LU_DESCThe LU_DESC is a general text field from the map legend. The amount of detail may vary between surveys
SOIL_SYSThe SOIL_SYS field is the soil classification system used to describe the soil in the land unit description
SPECIES_ 3Where 3 dominant vegetation species described in a land unit.The order of species listed determines their dominance.
SPECIES_1The dominant vegetation species described in a land unit. The order of species listed determines their dominance
SPECIES_2Where 2 dominant vegetation species were described in a land unit. The order of species listed determines their dominance
