Description

Abstract:

This land resources survey describes the polygon information on the map unit boundaries of the South East area of Bathurst Island, Northern Territory.
The survey was conducted in 1979-80 at scale 1:50 000 and covers an approximate area of 28,360ha.
The purpose of this survey was to identify land suitable for agriculture by determining the land resources present and to assess land capability for the required uses.

Core attributes describing the land units, as defined by this department, were added to the spatial dataset in November 2011.

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 (ArcGIS/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 DATA:
Survey teams navigated during field operations with topographic maps, aerial photographs and prismatic compass. 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. Attribute values, as described in the Data Dictionary below, have been added to each polygon.

Logical Consistency:GIS editing tools were used to rectify all overshoots and undershoots in line work. Polygon topology rules applied are; must not overlap, must not have gaps and each polygon has only one label.

Completeness:Complete

Data Dictionary

AttributeAttribute DescriptionPossible CodeCode Description
LAND_UNITAlias: Land Unit
the land unit label from the spatial dataset (eg 9a2)
LF_CLASSAlias: Landform Classification
the landform classification has been adopted by the dept across a number of surveys since 2000 to group land units into broad landform entities
LF_DESCAlias: Landform Description
includes details about landform, and usually general notes pertaining to slope, surface gravel and other details describing the land unit
SOILAlias: Dominant Soil Type
The dominant soil order described in a land unit is recorded.
SOIL_DESCAlias: 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. It is recommended that where possible soils are translated to an order in the Australian Soil Classification (Isbell 2003).
SPECIES_1Alias: Veg Species 1
The dominant vegetation species described in a land unit are recorded under SPECIES_1, SPECIES_2 and SPECIES_3 respectively using non abbreviated Latin names. The order of species listed determines their dominance.
SPECIES_2Alias: Veg Species 2
where 2 dominant vegetations species are recorded in a land unit
SPECIES_3Alias: Veg Species 3
where 3 dominant vegetations species are recorded in a land unit
SURVEY_IDAlias: Survey Identification
the first five characters from the corporate survey code
SURVEY_NMEAlias: Survey Name
the full name of the report to which the mapping refers (or the original survey report if several surveys have been amalgamated)
VEG_DESCAlias: Vegetation Description
Vegetation community is described; dominant species and its structure are recorded.
VEG_STRUCAlias: Vegetation Structure
The dominant vegetation structure in a Land unit is recorded. It is determined according to the Vegetation Classification scheme used to derive the data.
VEG_SYSAlias: Veg Classification System
vegetation classification system used to determine and describe the vegetation structure in a Land unit description.
