Title: NEW SOUTH WALES DCDB COUNTY BOUNDARIES
Custodian: Department of Information Technology and Management (LPI)
Jurisdiction: New South Wales
There are 1034 Digital County boundary layers covering New South Wales. These layers contain County boundary details and are coincident with the base polygon/tag layers. The layers are a component of the New South Wales Digital Cadastral Database.
- BOUNDARIES
- LAND Cadastre
- 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:
Data was captured from stable base Rural Cadastral MasterTransparencies and Urban Cadastral master Transparencies produced by the Land Information Centre. Data was captured using a combination of Table Digitisation, Scanning, Data Import and Coordinate Geometry. Quality control processing was performed by the Land Information Centre.
Positional accuracy:
Horizontal Accuracy - Ten percent of well defined points tested will not be in error by more than 0.5mm of scale of source document.
Attribute accuracy:
All DCDB data and linkages within the Genamap/Oracle environment are subject to automatic verification, ensuring 100% data integrity.
Logical consistency:
All points are labelled
All lines intersect at nodes
Lines do not cross unintentionally.
All lines do not exist. The data may contain construction lines.
There are no duplicate lines.
Lines do not overshoot or undershoot.
All lines are not labelled.
All polygon boundaries close.
All polygons are labelled.
All points, lines and polygons are topologically related.
Where data is stored in partitions, these are edge matched against adjoining partitions where applicable.
Completeness:
Spatial data is complete for the entire data set.
Attribute data is available for the whole data set. There are no data thresholds used.
This dataset description complies with ANZLIC Core Metadata Guidelines Version 2 (February 2001) and XML DTD ANZMETA NSW NRIMS Page 1 v1.0 which extends ANZMETA 1.3 (metadata validation date: 2004-07-11)
