SI-53 Port Augusta 1:1 Million General Reference Topographic Map

This map is part of a series that comprises 50 maps that cover the whole of Australia at a scale of 1:1 000 000 (1cm on a map represents 10km on the ground). Each standard map covers an area of 6 degrees longitude by 4 degrees latitude or about 590 kilometres east to west and about 440 kilometres from north to south. These maps depict natural and constructed features, including transport infrastructure (roads, railway airports), hydrography, contours, hypsometric and bathymetric layers, localities and some administrative boundaries, making this a useful general reference map.

Topographic maps show contours, spot elevations, streams, roads, buildings, place names, vegetation and administrative boundaries. They are used by emergency services, environmental resource managers, engineers and others for planning, development and recreational activities.

If you would like to use this map in the field, then we can supply it on waterproof/tearproof DuPont™ Tyvek®. Tyvek® is made of pure polyethylene fibres (plastic) but has the properties of paper, which means it is foldable.

We can also laminate this map, which will allow you to draw on it in whiteboard marker or apply our map dots to locations of interest without permanently marking the map. The lamination also makes the map very durable and protects against tears and stains.

Coverage: The whole of Australia is covered with 49 maps (please refer to Status). National coverage was first completed in 1975.
