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.

Attribute Attribute Description Possible Code Code Description LAND_UNIT The LAND_UNIT field is the land unit label from the spatial dataset (ie.9a2). LF_CLASS Landform class is a system adopted by the department. The categories do not conform to national criteria even though some have been sourced from Australian Soil and Land Survey - Field Handbook (Mc Donald et.al. 1998). LU_DESC The LU_DESC is a general text field from the map legend. The amount of detail may vary between surveys SOIL_SYS The SOIL_SYS field is the soil classification system used to describe the soil in the land unit description SPECIES_ 3 Where 3 dominant vegetation species described in a land unit.The order of species listed determines their dominance. SPECIES_1 The dominant vegetation species described in a land unit. The order of species listed determines their dominance SPECIES_2 Where 2 dominant vegetation species were described in a land unit. The order of species listed determines their dominance SURVEY_ID The SURVEY_ID field is the first five characters from the corporate survey code. SURVEY_NME The SURVEY_NME is the full name of the report to which the mapping refers VEG_STRUC Structural classes from NVIS (ESCAVI 2003), Walker and Hopkins (1998) and Specht (1970) classification schemes VEG_SYS The National Vegetation Information System (NVIS) classification system
