Description

Abstract:

This dataset provides polygon information on the map units boundaries of Darwin River Dam and Manton Dam Catchments, Northern Territory. The purpose of this survey was to map, describe and evaluate the land resources to assist in the development of a catchment management plan.

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:POLYGON DATA
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.

POINT SOURCE DATA
Site point coordinates derived from a geographic positioning system with general accuracy of within 10-50m.

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 topogical 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 was done to unsure that all classified polygons are closed, nodes are formed at intersections of lines and that each polgon has only one label.


Completeness:Complete.

AttributeAttribute DescriptionPossible CodeCode Description
LAND_UNITThe LAND_UNIT field is the land unit label from the spatial dataset (ie.9a2).
LF_CLASSLandform 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_DESCThe LU_DESC is a general text field from the map legend. The amount of detail may vary between surveys
SOILThe dominant soil order described in a land unit is recorded.
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.
SURVEY_IDThe SURVEY_ID field is the first five characters from the corporate survey code.
SURVEY_NMEThe SURVEY_NME is the full name of the report to which the mapping refers
VEG_STRUCStructural classes from NVIS (ESCAVI 2003), Walker and Hopkins (1998) and Specht (1970) classification schemes.
VEG_SYSThe National Vegetation Information System (NVIS) classification system.
