Description

Abstract:

GEODATA Coast 100k is a vector representation of the topographic features depicting Australia's coastline, and State and Territory borders. It provides a fundamental layer on which you can build a wide range of applications. The coastline component is primarily sourced from the 1:100 000 scale National Topographic Map Series produced by Geoscience Australia and the Royal Australian Survey Corps. The coastline represents the position of the Mean High Water, the seaward edge of coastal mangroves, inlet closing lines and those parts of the coastline defined as indefinite.

Lineage:

The coastline component of the GEODATA COAST 100K 1992 product is primarily sourced from the 1:100 000 scale National Topographic Map Series produced by Geoscience Australia and the Royal Australian Survey Corps. Two 1:100 000 scale sheet areas over Brisbane were produced by the Queensland Government. Data covering Tasmania was derived from maps produced by Geoscience Australia and the Tasmanian Government. The coastline of Western Australia was captured by its survey agency and from from reproduction material supplied by Geoscience Australia. The positions of the State and Territory borders were mainly derived from survey coordinate data and the 1:100 000 scale topographic series. The coordinate data were supplied by various State and Territory survey agencies and Geoscience Australia. Where State borders follow natural features, data were captured from 1:100 000 scale mapping produced by Geoscience Australia or the Royal Australian Survey Corps.

NOTE: The use of survey data in GEODATA COAST 100K 2004 does not imply that the data are suitable for any legal interpretation of State/Territory borders.

Positional accuracy:

GEODATA Coast 100k 2004 data complies with the following statement of horizontal accuracy: "The summation of errors from all sources results in data with a standard deviation of 50 metres for well defined points". Alternative and equal ways of expressing this error are: not more than 10% of well defined points are in error by more than 80 metres; and in the worst case, a well defined point is out of position by 150 metres.

Attribute accuracy:

Attribute accuracy is a measure of the degree to which the attribute values of features agree with the information on the source material. The allowable error in attribute accuracy ranges from 0.5% to 5% at 99% confidence level. Where less than 1% of attribute errors are permissible the entire population is tested. Where a less stringent limit is set for allowable errors a random subset of the relevant features in the tile is generally tested. The sample size is determined from statisitical tables using the known population size of the relevant feature. A full description of the checks on the data, the test sample size and the allowable error are provided in the Product User Guide supplied with the data.

Logical Consistency:

Logical consistency is a measure of the degree to which data complies with the technical specifications. The data were tested using a mixture of UNIX scripts and ArcInfo commands which were independent of the production system. Graphical tests were used to check such things as intersections, polygon closure, minimum size of polygons and topological relationships. A full description of the checks on the data, the test sample size and the allowable error are provided in the Product User Guide supplied with the data.

Completeness:

Only features listed in the GEODATA COAST 100K 2004 data dictionary have been captured from the map source material. The completeness was tested by overlaying symbolised plots of the data on the source material and carrying out a visual comparison.
