1:250 000 Scale NATMAPS
This series covers the whole of Australia at a scale of 1:250 000 (1cm on a map
represents 2.5 km on the ground) and comprises 513 maps. This is the largest scale at
which published topographic maps cover the entire continent.
Each standard map covers an area of 1.5 degrees longitude by 1 degree latitude or
about 150 kilometres from east to west and 110 kilometres from north to south. There
are about 50 special maps in the series and these maps cover a non-standard area. Typically,
where a map produced on standard sheet lines is largely ocean it is combined with its
landward neighbour.
These maps contain natural and constructed features including road and rail infrastructure,
vegetation, hydrography, contours (interval 50m), localities and some administrative
boundaries. Some maps are supplemented by relief shading.
The topographic map and data index shows coverage of the sheets.
