Australian Mineral Blocks 2006 - Geodatabase

The dataset was created by Geoscience Australia using the framework described in Section 33 of the Offshore Minerals Act 1994.


The international, scheduled areas and coastal waters used in this dataset are those found in the historical Australian Maritime Boundary Dataset 2006 (AMB2006).


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 known to millimetre precision. The corner coordinates of blocks are now defined to a high precision, and can be found by querying the appropriate point.


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 AMB2006

-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 Offshore Minerals Act, the area of a block has no relevance. Therefore the area figure is provided solely for reference.

Resource lineage

Statement

The dataset was created internally in Geoscience Australia based on the arrangements prescribed under Section 17 of the Offshore Minerals Act 1994. To maintain lineage with the Act, a points database was constructed first in AGD66 dividing the area into 1 by 1 blocks (1 = 1 minute), to ensure proper presentation of the blocks in any projection additional vertices were inserted every 30 (30 seconds). The points were transformed to the GDA94 datum using the prescribed NVT2 framework where available, outside this area a 7 parameter transformation was used. The blocks were then made by connecting the pertinent points together into polygons.
