The 1:250K scale topographic maps are now available in GeoPDF format which is an extension to the standard PDF file format that can be viewed using Adobe Acrobat.

These digital maps appear identical to the published paper maps and include all the standard features such as roads, watercourses and contours, as well as the full legend and full feature symbology.

Unlike other digital maps these GeoPDF maps maintain resolution regardless of zoom extents and are georeferenced to be directly compatible with GPS and other coordinated geographic data. For GPS users it highlights their current location on the map.

The high resolution ensures that regardless of how far the user zooms into the map, the clarity of annotation and symbology is maintained. In addition, coordinate locations and distances can be retrieved automatically using a mouse.

A plug-in to view GeoPDF using the Adobe Acrobat viewer is available as a free download.

The 1:250K GeoPDF topographic maps are available as a free download or through Geoscience Australia's MapConnect.
