DescriptionAbstract: Land system mapping for the pastoral area of Western Australia (Version April 2018). Most mapping is at scale 1:250, 000, except for Wiluna-Meekatharra (1:506, 880). A desktop mapping exercise was carried out in 2007 to update the original 1:1,000,000 CSIRO Kimberley Region surveys to make them suitable for use in 1:100, 000 scale pastoral lease mapping. Survey program is in progress and some areas are yet to be surveyed. Most surveys are accompanied by a Technical Bulletin report which provides more detailed information.

For map production purposes, land systems are grouped into Land Types. A standard colour has been assigned to each land type for map production purposes.

Data QualityLineage: Data compiled from field traverses and assessment and interpretation of aerial photography. This was transferred onto georeferenced base maps and digitised. Most surveys have been amended from their published mapping to facilitate edge matching with adjoining surveys to provide a seamless coverage.

Attribute data is stored in a separate Oracle map unit database, but key attribute data is provided with the spatial data.

Positional Accuracy: Variable depending upon scale of survey + or – 250 to 500 m.

Attribute Accuracy: Land system level mapping. Unmapped components (land units, WA soil groups) are usually described in survey reports and apportioned to map units.

Logical Consistency: Topological errors checked and corrected using ArcGIS 10 and GeoMedia Professional.

Completeness: Survey program is in progress. Southern Goldfields survey is in progress.
