Description

Abstract:

This polygon spatial dataset provides information on the land unit boundaries of the Upper Mary River Catchment, Northern Territory and describes dominant landform, soils and vegetation.

The survey area of 5643 km2 is located approximately 120 km south east of Darwin and south of the Arnhem Highway. The area includes large sections of the Mary River National Park and the western borders of Kakadu National Park. The original field survey was undertaken in 2000 and 2001 at a mapping scale of 1:50,000.
Core attributes describing the land units, as defined by this department, are included in the spatial dataset and described in the Data Dictionary in this record.

The spatial data and the accompanying report, Land Resources of the Upper Mary River Catchment - Resource Assessment and Degradation Survey, provide a comprehensive land resource information base on which to plan and achieve sustainable resource management, conservation and development in the catchment.

Data Quality

Lineage:The map unit boundaries were interpreted by land resource officers in 1998-2002 at scale 1:50,000.
Map unit boundaries were derived using aerial photography, satellite imagery, geological and topological data. Field data (site information) described and classified according to national standards.
Map unit polygons collected via geographic information system (ARC/MapInfo).
The department's core set of descriptive attributes for landform, soil and vegetation were attached to the polygons in October 2006.

Positional Accuracy:Positional accuracy is based on digital 1:20,000 aerial photography rectified to 1:100,000 topographic data and Northern Territory cadastral information.
Site data locations recorded using a non-differential GPS (2002).

Attribute Accuracy:The attribute information conforms to the 'Australian Soil and Land Survey Field Handbook' at time of capture.
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. The department has assigned a list of core attribute values, described in the Data Dictionary below, to each polygon.

The attribute naming format uses 10 characters with no spaces to be suitable for an ESRI shape-file format. An alias attribute name is applied to an ESRI file geo-database format.

Logical Consistency:GIS editing tools were used to rectify all overshoots and undershoots in linework. Arc/Info topological 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 ensure 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

Attribute Attribute Description Possible Code Code Description

01. SURVEY_NME Alias: Survey Name
The name of the survey area or report to which the mapping refers

02. SURVEY_ID Alias: Survey Identifier
A department code that usually refers to the first five characters from the original survey site sheet.

03. LANDUNIT Alias: Land Unit
The LAND_UNIT field is the land unit label from the spatial dataset (ie 9a2).

04. LF_CLASS Alias: 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).

05. SOIL_SYS Alias: Soil Classification System
The soil classification system used to describe the soil in the land unit description

06. SOIL Alias: Dominant Soil Order
The dominant soil order described in a land unit is recorded.

07. VEG_SYS Alias: Veg Classification System
The National Vegetation Information System (NVIS) classification system.

08. VEG_STRUC Alias: Dominant Veg Structure
Vegetation structural classes from NVIS (ESCAVI 2003), Walker and Hopkins (1998) and Specht (1970) classification schemes

09. SPECIES_1 Alias: Veg Dom Species 1
The dominant vegetation species described in a land unit. The order of species listed determines their dominance.

10. SPECIES_2 Alias: Veg Dom Species 2
Where 2 dominant vegetation species were described in a land unit. The order of species listed determines their dominance.

11. SPECIES_3 Alias: Veg Dom Species 3
Where 3 dominant vegetation species described in a land unit. The order of species listed determines their dominance

12. LF_DESC Alias: Landform Description
Landform description includes details about landform, and general notes pertaining to slope, surface gravel and other details describing the land unit.

13. SOIL_DESC Alias: Soil Description
Soil description includes an ASC or Northcote/other soil classification and usually includes colour, soil depth and other notes describing the soil.

14. VEG_DESC Alias: 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.

15. DOUBLE_LAB Alias: Land Unit Other Component
Used where a land unit label shares 2 descriptions.
