Surficial geology (National Geoscience Dataset)  

Authors / CoAuthors

Abstract

This dataset is derived from the 1:2,500,000 scale geology of Australia (1976).The surficial cover theme was derived from stipple patterns on the original published maps, overprinting the bedrock geology polygons. It has polygon topology with attribution giving a description and a numerical code for each map unit. Map units represent 5 superficial Cainozoic units and exposed bedrock. The data was originally captured by AGSO and passed to NRIC (now ARDC) for translating, cleaning and final editing. ARDC acknowledges the following organisations for their contributions to the preparation of this dataset: Australian Geological Survey Organisation (AGSO) Australian National Parks and Wildlife Service (project initiation and financial support) This digital dataset was released in 1999 by ARDC, BRS.

Lineage

This dataset was captured by the Australian Geological Survey Organisation (AGSO) using their Optronics 5040 scanner/plotter scanning the individual colourseparates for the four quadrants which made up the Geology of Australia (1976). The layers geology, faults, structures and surficial were edited as raster datasets then vectorized. This was performed on AGSO's Intergraph System. An existing digital coastline and lakes coverage were added to the dataset and the data were tagged where required by a local contractor (Candata). The data set was passed to the National Resource Information Centre (NRIC - now Advanced Research and Development Centres, ARDC) as a multi-layer national coverage. NRIC was subsequently involved in translating the dataset into ARC/INFO format, cleaning the data, and the final editing of all layers. The dataset was reprojected to a WGS84 datum and spheroid based upon the assumption that the original data had an AUSTRALIA NATIONAL spheroid and AGD66 datum although the data itself specified a CLARKE1866 spheroid.
