Sahara SF51-07 — AUSTopo 1:250,000 Topographic Map (2025)

Great Sandy Desert dunefields, remote sandplains, and immense western desert horizons—mapped across one of Australia’s least accessible landscapes

Covering the Sahara sheet area in the western Great Sandy Desert, including country near the eastern margins of Karlamilyi National Park, this AUSTopo 1:250,000 map provides an authoritative regional view of exceptionally remote inland Western Australia. Parallel sand ridges, broad interdunal swales, spinifex-covered plains, claypans, drainage depressions, and isolated rocky rises define a landscape where reliable large-area context is indispensable.

With few formed access routes and vast distances between recognised features, the Sahara sheet is particularly valuable for geological and environmental fieldwork, land and heritage management, scientific research, and emergency coordination. It brings terrain, drainage, vegetation, remote tracks, named features, and positional grids together in one coherent view across culturally significant Country.

At 1:250,000 scale (1 cm = 2.5 km), this is the largest scale at which published topographic maps cover the entire Australian continent—ideal for regional planning, land management, emergency coordination, and serious remote-area navigation.
