Description

Abstract:

This dataset provides polygon information on the map unit boundaries of the Pine Creek Township Area, Northern Territory. The main purpose of this survey is for general resource inventory, evaluation for urban uses and evaluation for land use planning. Data collected were soil properties, geomorphology and vegetation.

Fieldwork for the survey area of 9.38 km2 was originally undertaken in 1977.

Core attributes describing the land units, as defined by this department, were added to the spatial dataset in December 2009.

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: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. Positional accuracy generally considered moderate.

POINT SOURCE DATA
Survey teams navigated during field operations with topographic maps, aerial photographs and prismatic compass's. Point source locations marked on aerial photography in the field. Positional accuracy considered within 300m but generally below 200m depending on the terrain. Site coordinates derived by transferring site locations from aerial photographs to topographic maps and coordinates calculated. In some cases sites have been georeferenced directly from aerial photography to Google Earth Web Map Server in MapInfo or ArcGIS.

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 topological consistency checks were performed to detect flaws in the spatial data structure. The dataset was cleaned, to eliminate any duplicates arcs and 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.

Data Dictionary

AttributeAttribute DescriptionPossible CodeCode Description
DOUBLE_LABAlias: Land Unit Other Component
Used where a land unit label shares 2 descriptions. (field only used when relevant)
LAND_UNITAlias: Land Unit
Land unit label from the spatial dataset (ie.9a2).
LF_CLASSAlias: Landform 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).
LF_DESCAlias: Landform Description
Landform description includes details about landform, and general notes pertaining to slope, surface gravel and other details describing the land unit.
SOILAlias: Dominant Soil Order
The dominant soil order described in a land unit is recorded.
SOIL_DESCAlias: Soil Description
Soil description includes an ASC or Northcote/other soil classification and usually includes colour, soil depth and other notes describing the soil.
SOIL_SYSAlias: Soil Classification System
used to describe the soil in the land unit description.
SPECIES_ 3Alias: Veg Dom Species 3
Where 3 dominant vegetation species described in a land unit.The order of species listed determines their dominance.
SPECIES_1Alias: Veg Dom Species 1
The dominant vegetation species described in a land unit. The order of species listed determines dominance.
SPECIES_2Alias: Veg Dom Species 2
Where 2 dominant vegetation species were described in a land unit. The order of species listed determines dominance.
SURVEY_ID Alias: Survey Identifier
The SURVEY_ID field is usually the first five characters from the corporate survey code.
SURVEY_NMEAlias: Survey Name
The full name of the report to which the mapping refers.
VEG_DESCAlias: Vegetation Description
The dominant species and its structure are recorded. Occasionally it will include `minor' vegetation communities also noted in the land unit description and/or notes specific to the community.
VEG_STRUCAlias: Dominant Veg Structure
Structural classes from NVIS (ESCAVI 2003), Walker and Hopkins (1998) and Specht (1970) classification schemes.
VEG_SYS Alias: Veg Classification System
The National Vegetation Information System (NVIS) classification system.
