Description

Abstract:

This spatial dataset provides information about the map unit polygons of the Tuyu and Yapilika Forestry Plantations, Melville Island, Northern Territory. The western survey area is Yalpilika and the eastern survey area is Tuyu-Three Ways and was mapped at a survey scale of 1:16,000. Core attributes were added to the map unit polygons in 2013.

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. In September 2013, additional attribute values, as described in the Data Dictionary below, were 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.

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

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_DESCAlias: Land Unit Description
The LU_DESC is a general text field from the map legend. The amount of detail may vary between surveys.

SOIL_SYSAlias: Soil Classification System
The soil classification system used to describe the soil in the land unit description
SPECIES_1Alias: Veg Species 1
The dominant vegetation species described in a land unit. The order of species listed determines their dominance.
