Description

Abstract:

This land resource polygon dataset was mapped at a survey scale of 1:100 000 and includes a description of the landforms, soils and vegetation for 237 land units.
The surveyed area of 74 502km2 is located 700km south west of Darwin and covers 23 major land holdings in the Victoria River District, (VRD) Northern Territory.
The objectives of the project were to map, describe and evaluate the pastoral lands of the VRD and provide this information to land managers, industry, government and other relevant stakeholders.

Data Quality

Lineage:Work compiled before1998: Original map unit boundaries delineated from aerial photographs and stereoscope interpretation. Map units transferred to topographic map sheets 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.
Additional work compiled after 1998: 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 (ArcGIS/MapInfo). Core landform, soil and vegetation attributes attached to map units with additional attributes unique to individual surveys.

June 2017 - survey area was extended to cover a gap with the neighboring land and veg survey over Gregory National Park. (see metadata record www.ntlis.nt.gov.au/metadata/export_data?type=html&metadata_id=2DBCB7711FA106B6E040CD9B0F274EFE)

Positional Accuracy:POLYGON DATA
Work compiled before1998: Map unit boundaries transferred from aerial photographs to topographic maps, using the best available topographic mapping at the time (generally 1:100 000) via a mapograph. 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 moderate to high.
Additional work compiled after 1998: 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 DATA
Work compiled before1998: Site point coordinates collected from a geographic positioning system with general accuracy of within 100m. Selective availability during this time prevented increased accuracy.
Additional work compiled after 1998: 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. 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
