Title: Location of some Australian towns
Custodian: IndexGeo Pty Ltd
Jurisdiction: Australia
The geographic coordinates of some towns of Australia are listed. These are useful to provide context for basic locality maps. The towns are not necessarily major towns, just well-spaced populated places to give some guidance on an otherwise featureless map.
This dataset is a comma-separated values CSV file with one entry per line (longitude, latitude, city name) ... town_aus.csv
There is also an example PNG image portraying the location of these towns with symbols and labels ... aus-se.png

- Australia excluding external territories - AUS
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: 9 00 00.0 S (-9)
- South bounding latitude: 44 00 00.0 S (-44)
- East bounding longitude: 154 00 00.0 E (154)
- West bounding longitude: 112 00 00.0 E (112)

information
Lineage:
Geographic coordinates were obtained from the AUSLIG Australian Place Names lookup service (which interrogates the "Gazetteer of Australia" dataset).
The simple listing was created with a text editor by copying and pasting the values that were returned from the Internet lookup service.
Positional accuracy:
Longitude and latitude are quoted to 3 decimal places. This is the precision supplied by the AUSLIG public Internet service.
Attribute accuracy:
The CSV file has 3 fields: city name, longitude, latitude. These parameters are validated by importing the CSV file with the mapping software Manifold and the map image is produced. The mapped locations and label names are visually checked with a graticule overlay.
To minimise potential human errors, the process was separately repeated. The resultant two data files were compared for differences using the UNIX utility "diff".
Logical consistency:
The CSV file has a consistent, well-structured format (explained above). Each entry is guaranteed to conform to that format.
Completeness:
The dataset is deliberately not complete - only some Australian towns are listed (i.e. those that are considered to be useful for basic mapping purposes).
The following towns and cities are currently included: Albany, Albury, Alice Springs, Bathurst, Bendigo, Bourke, Broken Hill, Broome, Burnie, Cairns, Coffs Harbour, Coober Pedy, Eucla, Hamilton, Katherine, Launceston, Mildura, Mount Gambier, Mount Isa, Newcastle, Oodnadatta, Port Augusta, Port Hedland, Queenstown, Rockhampton, Tamworth, Tennant Creek, Townsville, Wollongong.
Note that the capital cities are not included, as they are listed in the separate geospatial dataset called " Location of Australian capital cities".
The data file and an example map image are available from http://www.indexgeo.com.au/data/town-aus/ together with supporting documentation.
This dataset description complies with ANZLIC Core Metadata Guidelines Version 2 (February 2001) and XML DTD ANZMETA Resource 1.1 which extends ANZMETA 1.3 (metadata validation date: 2004-05-13)
