Access Constraint:The data is generally available for distribution within the Northern Territory. Charges may apply for both hard and digital copy. For digital information, a digital data agreement may be required. Please refer to the contact within this metadata.

Data Quality

Lineage:The Airfields of the NT is primarily sourced from the 1:250 000 scale National Topographic Map Series (NTMS) and the Royal Australian Survey Corps' Joint Operation Graphics (JOG) map reproduction material (reformat). Please refer to Auslig for information.

Positional Accuracy:The summation of errors from all sources results in data with a standard deviation of 100 metres for well defined features.
Please refer to Auslig for information.

Attribute Accuracy:The allowable error in attribute accuracy ranges from 0.5% to 5%, at a 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 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 TOPO-250K Data.

Logical Consistency:For the TOPO-250K 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 ARC/INFO 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 TOPO-250K Data User Guide supplied with the data.
Please refer to Auslig for information.

Completeness:All instances of a feature and its attribute values that appear on the source material have been captured unless otherwise stated in the selection criteria for that feature provided in the TOPO-250K Data User Guide supplied with the data. The completeness was tested by overlaying symbolised plots of the data on the source material and carrying out a visual comparison. Please refer to Auslig for information.
