Keep your paper maps away from direct sunlight when not in use, to prevent colours fading. Use 100+ gsm paper if you require greater paper durability for maps that will be stored flat or rolled.Use 90 to100 gsm paper for maps that will be folded.For example, a TIFF image which is 9393 x 11144 pixels and 400 dpi is calculated to be 59.68 cm x 70.76 cm and therefore should be printed on A0 paper.Select a paper size larger than the image size and print with the setting ‘print actual size’ for an accurate scale.Calculate image width using the same formula with the pixel width number.Multiply by the length in inches by 2.54 to convert to centimetres.To calculate image length, divide pixel length by dpi (this will give you the length in inches).To find the size of the image in centimetres, open the image options to find the pixel dimensions and resolution in dots per inch (dpi) and follow the steps below: Maps at 1:50 000 scale are TIFF images, and the image size in centimetres must be calculated to determine a suitable paper size.Maps at 1:100 000, 1:250 000 and 1:1 million scale are in PDF and/or GeoPDF format which have embedded print page size.Maps should be printed on a large-format size paper, for example the A0 paper size (84.1cm x 118.9 cm).To print a full-size topographic map, download the map from our indexes above and use the following specifications when placing your order with a print provider: If you cannot access a printing service locally, some printers provide facilities for customers to electronically upload or send files to be printed and returned to you by post.

Coverage: Whole of Australia covered with 49 maps (please refer Status).Coverage: Covers the whole of Australia with 516 maps.Coordinates: Geographical and either AMG or MGA coordinates.Unpublished maps are available as compilations (compilations are accurate plots from photogrammetric models using aerial photographs with established control point framework). Coverage: Australia is covered by more than 3000 x 1:100 000 scale maps, of which 1600 have been published as printed maps.Projection: Universal Transverse Mercator (UTM).About 2761 maps have been published to date. Coverage: Partial coverage, predominantly in northern Australia, along major transport routes, and other selected areas.For availability of these maps please check with your local state mapping agency: Please note that Geoscience Australia does not have 1:25 000 scale topographic maps in its collection. To use these indexes, click on the link to relevant map index, zoom or search for an area of interest, then click the desired box outlining map extents and follow the prompt to download the map. Once downloaded, maps can be printed by anyone and are suitable for large-format printing – see ‘How to print our maps’ below for instructions.īelow are links to digital versions of our indexes for 1:50 000, 1:100 000, 1:250 000 and 1:1 million scale Australian topographic maps. Our digital maps are available for free download to any device. We are currently reviewing how we deliver topographic information.
