1:100 000 Australia topographic map sheet index for 1:100 000 map sheets over Western Australia.

1:50 000 Australia topographic series map sheet index for 1:50 000 map sheets over Western Australia.

This dataset is a 1:250 000 map sheet index for available geological maps produced by the Geological Survey of Western Australia.

This dataset is a 1:1 000 000 geological map sheet index for available surface geological maps produced by the Geological Survey of Western Australia (GSWA).

This dataset is a 1:50 000 geological map sheet index for available geological maps produced by the Geological Survey of Western Australia (GSWA).

The digital '1:2 500 000 geological map of Western Australia' comprises four layers: the primary 1:2 500 000 State interpreted bedrock geology, the 1:2 500 000 State Cenozoic geology, the 1:2 500 000 State interpreted dyke suites, and the 1:2 500 000 State interpreted bedrock geology structural lines. The 1:2 500 000 interpreted geology contains geoscience data covering themes such as geology and tectonic boundaries that have been digitally rolled up from 1:500 000 data sources for optimal display at 1:2 500 000 scale. The Cenozoic geology layer can be superimposed over the bedrock layer to allow the extension of older bedrock geology under Cenozoic cover where geological and geophysical information permits, and to depict Cenozoic paleovalleys and additional significant Cenozoic cover. The dyke suites layer is primarily interpreted from aeromagnetic data, using mapped dyke extents as a guide. Individual dykes are assigned to named dyke suites wherever possible. The attribution of linear structures and dykes as concealed or exposed takes into account both the interpreted bedrock and the Cenozoic geology layers and does not reflect regolith cover. Detailed fault attribution has been simplified from the 1:500 000 scale, except in the case of major fault systems or tectonic boundaries. The nomenclature and hierarchy of lithostratigraphic units is based on the GSWA weekly updates from the Explanatory Notes System (ENS). In order to provide the most up-to-date geological information for the units in question, attribution from the original source is modified to remove superseded stratigraphic units, display correct stratigraphic relationships and include more recent geochronology. Stratigraphic units are mostly displayed at greater than or equal to Group or Suite level; Subgroups and Formations are only displayed where areal extent warrants it and the unit does not have a higher order parent.

"The ‘1:2 500 000 major crustal boundaries of Western Australia, 2021’ digital layer is a regional compilation of interpreted crustal boundaries that penetrate the lithosphere or bound tectonic units at the terrane or province scale. These boundaries have been interpreted and extrapolated from a variety of geological and geophysical datasets, primarily seismic reflection profiles, outcrop geology, and potential field data (gravity and aeromagnetics). Tectonic events ascribed to each boundary are defined in the GSWA Explanatory Notes Database (February 2021). The positional accuracy of these boundaries is low, due primarily to their crustal scale and uncertainties in interpreting the primary data sources, and consequently this map is best used at the nominal scale or smaller.

This map is part of the AUSTopo - Australian Digital Topographic Map Series. It 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 516 maps. This is the largest scale at which published topographic maps cover the entire continent. Each standard map covers an area of approximately 1.5 degrees longitude by 1 degree latitude or about 150 kilometres from east to west and at least 110 kilometres from north to south. The topographic map shows approximate coverage of the sheets. The map may contain information from surrounding map sheets to maximise utilisation of available space on the map sheet. 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.
