This GIS dataset shows where Geoscience Australia (GA) has acquired regional seismic reflection data as a part of Australian Government's Onshore Energy Security Program (OESP) in collaboration with State and Territory geological surveys, AuScope and Australian National Seismic Imaging Resource (ANSIR). During 2006-2011 GA collected over 6,500 line kilometres of new world-class seismic reflection data within Australia for use by industry and government. This dataset is generated from files containing CDP (Common Depth Point) coordinates of all OESP seismic surveys. The CDP line is a curve of best fit through the midpoints between sources and receivers, which optimises the fold of the data while minimising the subsurface area of reflections contributing to each nominal CDP. Each trace (source-receiver pair) is allocated to the nearest CDP bin to its midpoint. The interval between each CDP traces is 20 metres.

Data quality

Lineage:

CDP line coordinates of all OESP seismic surveys generated during processing of seismic data as a result of a crooked line geometry definition from seismic station coordinates which are all surveyed points, to 3rd order surveying standards. The produced Microsoft Excel files with CDP coordinates were used to create the lines coverage in ArcInfo, adding the seismic line names and CDP numbers.

Positional accuracy:

CDP line coordinates derived from seismic station coordinates which are all surveyed points, to 3rd order surveying standards and extracted from archived Microsoft Excel files so positional accuracy is high.

Attribute accuracy:

The attribute assigned is the seismic line name, and the names derived from information already realeased in the public domain.

Logical Consistency:

Not applicable.

Completeness:

The dataset coverage is complete for the OESP Seismic Survey from 2006 to 2011.
