Title: Land Capability for NSW
Custodian: Department of Land and Water Conservation (DLWC)
Jurisdiction: New South Wales
As part of a basic inventory of the rural lands of NSW, land capability maps of the Eastern and Central Divisions were prepared by the then Soil Conservation Service. The standard eight-class classification was used based on an assessment of the biophysical characteristics of the land, the extent to which these will limit a particular type of land use and the technology available for land management. The classification has an hierarchical sequence, ranging from land with the greatest potential for agricultural or pastoral use, to that which is entirely unsuitable for either.

- Geographic extent name:
- NEW SOUTH WALES - State or Territory - New South Wales
- Geographic extent polygon:
- 141 -37.5, 154 -37.5, 154 -28, 141 -28, 141 -37.5
Note: The format for each Geographic extent name is: Name - Identifier - Category - Jurisdiction (as appropriate)
Geographic bounding box:
The bounding box encloses the maximum extents of the dataset. There may be voids or gaps within the bounding box, depending on the defined coverage of the dataset. Outer bounding rectangle as Latitude/Longitude coordinates based on the WGS84 datum (expressed as both Degrees Minutes Seconds and as decimal Degrees):
- North bounding latitude: 28 00 00.0 S (-28)
- South bounding latitude: 37 30 00.0 S (-37.5)
- East bounding longitude: 154 00 00.0 E (154)
- West bounding longitude: 141 00 00.0 E (141)
Lineage:
Standard aerial photography was the principal information base for interpretations which were mapped directly onto relevant 1:100000 topographic sheets. Where 1;100000 sheets were unavailable, 1:25000 or 1;50000 sheets were used and the information reduced to 1:100000. Originally each 1:100000 base map sheet was compiled from topo field maps at varying scales and hand drawn. In the late 1980's, source data (base maps on plastic film) were digitised or scanned on a 1:100000 tile basis.
Positional accuracy:
The information is only reliable at the scale of publication. A minimum mapping unit of 100ha. has been set as the standard of reliability. Smaller units may have been mapped if the class unit could be easily delineated, or if it was an area of critical hazard etc.
Attribute accuracy:
Tags checked as part of the quality assurance procedures, including a visual check of polygon tags against source document. Climate, soils, geology, geomorphology soil erosion, site and soil drainage characteristics and land use data are all considered in determining land capability. On completion of classification, maps were field checked. Detailed observations were made along most access tracks and roads. Following corrections, a second person examined the data using aerial photo interpretation.
Logical consistency:
All lines and polygons are labelled. All duplicates are eliminated, lines do not undershoot or overshoot. Polygons and lines are matched with adjoining map tiles. Topological consistency verification was performed as part of the quality assurance procedures using Genamap software and a series of checking procedures implemented (including visual check against original).
Completeness:
Spatial data capture is complete for the entire dataset. Complete for presentation and usage at publication scale of 1:100000 only. Mapping exclusions include National and State Parks, State Forests, restricted water supply catchments, lands set aside for soil conservation management and urban zonings.
This classification system does not reflect existing land uses. Instead, it indicates the maximum potential safe use of the land for crop production, pasture improvement and grazing.
