Commonwealth Fisheries 2006Note: This metadata describes the dataset in accordance with the ANZLIC (Australia New Zealand Land Information Council) Core Metadata Guidelines Version 2. Dataset citationANZLIC unique identifier: ANZCW0703008948 Title: Commonwealth Fisheries 2006 CustodianCustodian: Geoscience Australia Jurisdiction: Australia DescriptionAbstract: Commonwealth Fisheries 2006 is a digital representation of the limits of all Commonwealth Fisheries around Australia and its External Territories (except for the Australian Antarctic Territory), as set out in the Fisheries Management Regulations 1992 and/or relevant Management Plans administered by the Australian Fisheries Management Authority (AFMA). In the event of a discrepancy between the digital data and the Management Regulations or Management Plans, the Management Regulations or Management Plans take precedence. See www.afma.gov.au/fisheries for further information. ANZLIC search words:

Access constraints: The data are subject to Copyright. Data files may be downloaded from Geoscience Australia's website at www.ga.gov.au/download/. A licence agreement is required. Free Data DownloadData qualityLineage: Descriptions of Commonwealth Fisheries boundaries, found in the Fisheries Management Regulations 1992 and/or relevant Management Plans, were interpreted and digitised into a Geographic Information System (GIS), and subsequently attributed. Where national maritime limits formed part of these boundaries, current AMB V2.0 data was directly extracted and appended into the coverages. Where fisheries included coastline or low water information, GEODATA Coast 100K coastline data was used as it provided a nationally consistent dataset; was of the right level of detail for the project (eg closed river mouths); and, resulted in a manageable file size for distribution. Any intersections between boundary lines were rigorously calculated using specialised geodetic software. In the event of a discrepancy between the digital data and the Management Regulations or Management Plans, the Management Regulations or Management Plans take precedence. Positional accuracy: The positional accuracy of the data is affected by three main issues: - The precision of the coordinates shown in legislation: Generally coordinates are only stated to the nearest minute of arc in the Regulations and/or Management Plans. This is equivalent to a precision of approximately one nautical mile (or approximately +/- 900 metres). In some cases the boundary follows a Treaty line and the coordinates are stated to the same precision as recorded in the Treaty (usually to the nearest second of arc). - The positional accuracy of the coastline data: The positional accuracy of the GEODATA Coast-100K data is stated as "Not more than 10% of well-defined points are in error by more than 80 metres; and in the worst case, a well defined point is out of position by 150 metres." It should also be noted that this data depicts mean high water rather than the low water mark which is the true boundary for many of the fisheries. - Datum issues: The coordinates stated in the Regulations and/or Management Plans are generally referred to the AGD66 datum. Attribute accuracy: Fishery line and polygon features were attributed with descriptive information relating to the fishery as recommended by AFMA, as well as with a Quality Information pointer, and a Unique Feature Identifier (UFI). Line source feature code was kept as a separate attribute item. Manual checks were used in ArcInfo to verify that 100% of all mandatory fields were filled and that there were no spelling errors. Logical Consistency: The GIS software ArcInfo was used to do a visual topological consistency checks to detect flaws in the spatial data structure and to flag them as errors. This check ensures that all classified polygons are closed, nodes are formed at the intersection of lines and that there is only one label within each polygon, etc. All coverages are built for polygons and free of artifacts Completeness: All current Commonwealth Fisheries have been represented in the GIS database. Internal fisheries and closure areas have not been included, except for closures within Heard and McDonald Islands Fishery and the East Coast Deepwater Trawl Sector. It is expected that the data set will be maintained and updated as changes occur. The changing nature of Australia's coastline and hence the various national maritime boundaries may also influence changes to the fisheries data set. Contact information
