GEODATA TOPO 10M 2002 provides a fundamental basis layer of geographic information on which you can build a wide range of applications. This data has been derived primarily from GEODATA TOPO 250K Series 1 and contains the following features: State borders, roads, railways, populated places, rivers and lakes, coastline and islands, bathymetric and land contours, and spot locations.

Data quality

Lineage:

The key source for production of the Builtup Areas, Drainage, Framework, Localities, Rail Transport, Road Transport and Waterbodies layers was the GEODATA TOPO 250K Series 1 product. Some revision of the Builtup Areas, Road Transport, Rail Transport and Waterbodies layers was carried out using the latest available satelite imagery. The primary source for the Spot Heights, Contours and Offshore layers was the GEODATA TOPO 10M Version 1 product. A further element to the production of GEODATA TOPO 10M 2002 has been the datum shift from the Australian Geodetic Datum 1966 (AGD66) to the Geocentric Datum of Australia 1994 (GDA94).

Positional accuracy:

GEODATA TOPO 10M 2002 data comply with the following statement of planimetric accuracy: The summation of errors from all sources represents an error of 3400 metres on the ground for 1:10 million data. This will be rounded to 4000 metres for the GEODATA TOPO 10M product. Alternative and equal ways of expressing this error are: Not more than 10% of well-defined points are in error by more than 5600 metres, or in the worst case, a well-defined point is out of position by 12 000 metres.

Attribute accuracy:

For this product, attribute accuracy is a measure of the degree to which the attribute values of a feature agree with the source information on the source material. The allowable error in attribute accuracy ranges between 0% and 5%. 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 is generally tested. The sample size is determined from statistical 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 GEODATA TOPO 10M 2002 Data Quality Statement file supplied with the data.

Logical Consistency:

For the GEODATA TOPO 10M 2002 product, 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 procedure, test sample size and the allowable error are provided in the GEODATA TOPO 10M 2002 Data Quality Statement file supplied with the data.

Completeness:

All instances of a feature and its attribute values that appear in the source material have been captured unless otherwise indicated in the selection criteria. The completeness was tested by overlaying symbolised plots of the data on the source material and carrying out a visual comparison.
