GEODATA TOPO 5M 2004Note: This metadata describes the dataset in accordance with the ANZLIC (Australia New Zealand Land Information Council) Core Metadata Guidelines Version 2. Dataset citationANZLIC unique identifier: ANZCW0703006341 Title: GEODATA TOPO 5M 2004 CustodianCustodian: Geoscience Australia Jurisdiction: Australia DescriptionAbstract: The GEODATA TOPO 5M 2004 product is a national semaless data product aimed at regional or national applications. It is a vector representation of the Australian landscape as represented on the Geoscience Australia 1:5M general reference map and is suitable for GIS applications. The product consists of eleven layers : built up areas, contours, drainage, framework, localities, offshore, rail transport, road transport, sand ridges, spot heights and waterbodies. Offshore and Sand Ridge layers have been derived from 1:5M scale mapping by scanning stable base photographic film positives of the various layers of the original map production material. The remaining layers were sourced from the GEODATA TOPO 2.5M 2003 product. ANZLIC search words:

The remaining layers were sourced from the GEODATA TOPO 2.5M 2003 product. Positional accuracy: GEODATA TOPO 5M 2004 complies with the following statement of planimetric accuracy: "Not more than 10% of well defined points are in error by more than 2800m." Attribute accuracy: For this product, attribute accuracy is a measure of the degree to which the attribute values of a feature agree with the information on the source material. The allowable error in attribute accuracy ranges between 0% and 5%. Where less than 1% of errors are permissable, the entire population is tested. A full description of the checks on the data, the test sample size and the allowable error are provided in the product user guide of GEODATA TOPO 5M 2004. Logical Consistency: Logical consistency is a measure of the degree to which data complies with the technical specification. The data was tested using a mixture of ArcInfo and UNIX programs. This included checking of the naming of tables and files and graphical tests to check intersections, polygon closures, and minimum size of polygons and topological relationships. Completeness: All instances of a feature and its attribute values that appear on the source material are captured unless otherwise indicated. The completeness was tested by assessing the data against the supplied and quoted source material, carrying out visual comparisons and data comparisons as required. Contact information
