Description

Abstract:

The following datasets have been cropped to the Geographic Extent Polygon.

australian_permits.shp

This dataset (ANZLIC metadata 3559) represents the distribution of Petroleum titles (Pre 2002) for onshore and offshore Australia (clipped to polygon coordinate string). This attributed dataset is used in production of the "Petroleum Exploration and Development Titles" map published annually in April. Attributes and an additional lookup table contain information on the operator, dates of award and expiry, the number of 5' X 5' graticular blocks making up the title, the State which has jurisdiction, and the companies and their equity for each title.

Lineage:

australian_permits.shp

This dataset is generated from converted Microstation files used in production of the "Petroleum Exploration and Development Titles" map. Attributes are derived from Geoscience Australia's corporate Oracle PTAG (Petroleum Technical Advice Group) database currently under construction. The files are converted to an Arcinfo dataset and reprojected from the captured AGD66 datum to WGS84 datum. The data is checked and corrected if need be to maintain topology and regions are utilised to store multiple entities representing a single title. Attributes are extracted from the PTAG database and joined, on the title name, to the spatial dataset.

pipelines.shp

These datasets are converted from Microstation format files used in a map "Petroleum Exploration and Development Titles" published annually in April. Attributes have been added to comply with data standards and minor coding of line work has been achieved using annotation from the map. Further data has been added, specifically for the Bass Basin region.

Positional accuracy:

australian_permits.shp

Nominal Scale 1:5,000,000

Positional accuracy can vary as the spatial titles information is derived from a variety of sources. Data are supplied from the State and Territory mines departments as spatial datasets except Victoria who supply data as an ungeoreferenced CGM image (which is georeferenced in Microstation). These datasets are incorporated as-is so the positional accuracy is as supplied. The supplied accuracy of these datasets is not provided with the data.

Nominal Scale1:5 000 000

The positioning of data is highly subjective and should not be used as an accurate depiction of location.

Attribute accuracy:

australian_permits.shp

Highly variable due to the varied source of the original information.

The attribute information is derived from data supplied by the Commonwealth department of Industry, Science and Resources (ISR) for permits beyond the 3nm (nautical mile) boundary of State/Territory coastal waters, and State/Territory mines departments for all permits within that limit, including onshore permits. This is collated and entered into a continually updated Petroleum Titles database maintained by Geoscience Australia.

Logical Consistency:

australian_permits.shp

The GIS package (Arcinfo) was used to detect errors in the spatial data structure and make sure topology is maintained. This check ensures that all titles polygons are closed and that each polygon is uniquely identified. A visual check of the titles attributes is done prior to release and attributes are also checked within the database they are derived from.

pipelines.shp

A geoscientist visually inspected the finished dataset to make sure the attributes were accurate and the data were consistent spatially with current scientific information. Tests are also carried out on these data for data completeness, correct spatial representation, attribute accuracy, logical consistency and correctness, and where appropriate for compliance with Geoscience Australia's GIS data dictionary.

Completeness:

The dataset coverage is complete for marine areas of the Australian Jurisdictional Area.
