Sir Samuel 1:250 000 digital outcrop geologyNote: This metadata describes the dataset in accordance with the ANZLIC (Australia New Zealand Land Information Council) Core Metadata Guidelines Version 2. Dataset citationANZLIC unique identifier: ANZCW0703002906 Title: Sir Samuel 1:250 000 digital outcrop geology CustodianCustodian: Geoscience Australia Jurisdiction: Australia DescriptionAbstract: Mapping of outcrop geology on Sir Samuel 1:250 000 map sheet in the Eastern Goldfields, Western Australia, as part of the National Geoscience Mapping Accord (NGMA). Briefly, mapping consists of geological boundaries/units, faults, fractures, folds, veins, dykes, joints, linears, marker beds, trends, structural measurements, and mineral deposits.

Free Data DownloadData qualityLineage: The current Sir Samuel 1:250 000 outcrop geological map was compiled and generalised from published 1:100 000 outcrop geological maps of the area. Geological lines and polygons for the 1:100 000 maps were originally compiled from 1:25 000 or 1:50 000 aerial photographs. The compilation and generalisation process for the 1:250 000 map was done digitally on screen in Arc/Info at AGSO. Positional accuracy: The position accuracy of the current Sir Samuel 1:250 000 outcrop geological map is nearly as good as that in the published 1:100 000 geological maps in the area, from which the 1:250 000 map was compiled/generalised. Because the compilation/generalisation was done digitally, little position error was introduced during the compilation/generalisation process. Therefore, position accuracy is better than 100 to 200 m in most cases. Attribute accuracy: The bulk of attributes in this dataset are qualitative and quantitative geological observations and measurements. Classifications of lithology and linear geological features are largely interpretative, based on conventional mapping techniques (field observations, photo/imagery interpretation, sample collection and analysis), and adhere to well established and standardised classification schemes. Structural measurements are quantitative, measured using standard field mapping instruments. Logical Consistency: This dataset has been subject to independent post-production validation and testing. Up to eighty tests, most using a sampling regimen, have been carried out on the dataset to ensure its integrity. Tests are carried out for consistency, and where appropriate for compliance with Geoscience Australia GIS data dictionary. Although the validation procedure has not been subject to rigorous statistical analysis it is intuitively estimated that fewer than 5 per cent errors occur in those aspects of the data subject to validation. Completeness: The spatial data is complete for the entire Sir Samuel 1:250 000 sheet area. Contact information
