Australian Petroleum Blocks (2014) - Geodatabase

Australian Petroleum Blocks (2014) - Aligned with the current Australian Maritime Boundary Dataset (AMB2014)

The digital realisation of Australia's Graticular Framework as set out under the Offshore Petroleum and Greenhouse Gas Storage Act 2006.

ESRI Geodatabase.
The dataset was created internally by Geoscience Australia using the framework described in Section 33 of the Offshore Petroleum and Greenhouse Gas Storage Act 2006 (OPGGS Act) and previous Acts.
The international, scheduled areas and coastal waters used in this dataset are those found in the current Australian Maritime Boundary Dataset (AMB2014).

The dataset is comprised of both polygons and points created to very high precision, accurate to within millimetres.

The blocks have been cut by Australia's international boundaries, the scheduled areas and the coastal waters. Each block is assigned a polygon, including partial blocks. All blocks are titled with their block ID, and a list of vertices that make up the blocks. Each vertex of the dataset is also replicated as a discrete point in the points dataset.

The design of the dataset allows for the exact location of every vertex to be know to millimetre precision. The corner coordinates of blocks are now defined to a high precision, and can be found by querying the appropriate point.
Existing production licences AC/P17, AC/RL4, and AC/RL5 are included in the dataset.
The blocks are attributed with fields containing information on:
Block ID
Parent 1 Million Mapsheet
Offshore Area
Epoch of the boundaries used to cut the data - AMB2014
Datum
Origin of the mapsheet in AGD66
The position of all vertices in the block
The number of vertices in the block
The area of the block in acres
The area of the block in hectares
The calculation used to find the area of the blocks is estimated to be precise to better than 1%. This is considered to be sufficient as under the permit and licensing arrangements in the OPGGS Act, the area of a block has no relevance. Therefore the area figure is provided solely for reference.
