Introduction:

The Great Desert Tracks Mapping Expedition began after Hema Maps identified an area in Australia that had not been mapped since the 1970s and certainly never with GPS technology and detailed, on-the-ground field checking. The area was so vast it had to be mapped in two phases. The first phase included every trafficable road and track from the Great Australian Bight in the south to the Kimberley in the north and from near the Stuart Highway in the east to the Pilbara in the west, which amounted to about 48,000km of tracks and roads travelled. The first phase culminated in the release of four maps in 1999. The second phase was field checked in 2000 and continued along the same northern and southern boundaries as the earlier map sheets and reached across to Quilpie in south-west Queensland and White Cliffs in Outback New South Wales. The field checkers clocked up 45,000km while surveying the 25,000km of additional roads and tracks for the two new sheets, as well as several thousand further kilometres in the area covered by the original four map sheets. The results of these expeditions are now two new and four revised maps.
This CD contains all six Great Desert Tracks Maps:

Map Projection:
All of the Great Desert Tracks Maps are Lambert Conformal Conic Projections using the WGS84 datum. Contact Hema Maps for more information such as the standard parallels used.

Road Classifications:
The road and track classifications are based on a general assumption that map users are familiar with the often-rough condition of outback roads and tracks. Any unsealed road or track can be hazardous due to washouts, sand, mud or bull-dust patches and extreme corrugations. Use classifications as a general guide and always seek local advice.

GPS Plotted Roads and Tracks:
The PURPLE roads and tracks were accurately plotted with a GPS and laptop computer during the Great Desert Tracks Mapping Expeditions. Distances were also checked and have been rounded to the nearest kilometre (variations may occur due to wheel-slip and/or tyre pressure).

The RED road and track information has been compiled from AUSLIG 1:250,000 Geodata and other sources. The exact location and/or condition of these roads and tracks were not verified during the Expeditions so this information must therefore be treated with caution. (All highway information has been verified.)
