Treaties - Australian Maritime Boundaries 2014a (AMB2014a) - Geodatabase

Brief description

Geoscience Australia has the primary role in the delineation of Australia's domestic and international maritime limits and boundaries. An output of this activity is the development of the Australian Maritime Boundaries (AMB) data. AMB is a GIS data product, replacing AMBIS 2006, providing access to the data for Australia's maritime zones. Treaties - Australian Maritime Boundaries Dataset 2014 is a digital representation of Australia's international treaty boundaries. In the event of an inconsistency between AMB data and the limits under any treaty, the latter prevails. The data have been published by Geoscience Australia in consultation with other relevant Commonwealth Government agencies including the Attorney-General's Department, the Department of Foreign Affairs and Trade and the Australian Hydrographic Office. This version contains a number of technical amendments made on the basis of user feedback. These include: - Harmonisation of maritime boundaries, scheduled area and graticular block datasets in block SC51 The Treaties - Australian Maritime Boundaries Dataset 2014a comprises the maritime boundaries determined by treaties between Australia and neighbouring countries. All data coordinates are supplied in the GDA94 datum. Treaties - Australian Maritime Boundaries Dataset 2014a can also be viewed on-line via AMSIS (http://www.ga.gov.au/marine/jurisdiction/amsis.html). Product Specifications Coverage: Australia including all external territories Currency: May 2014. Coordinates: Geographical Datum: GDA94 (functionally equivalent to WGS84). Format: ESRI Geodatabase and REST web service - free online. The area of coverage of the Treaties - Australian Maritime Boundaries Dataset 2014 is for the whole of the Australian marine jurisdiction which includes waters adjacent to the mainland, offshore islands and External Territories. The geographical extent is approximately between the latitude limits of 8 S to 70 S and the longitude limits 39 E to 174 E. This dataset includes the following disclaimers: AMB data is a digital representation of the international maritime boundary treaties of Australia. In the event of an inconsistency between AMB data and the limits under the various treaties, the latter prevails.

Lineage

Maintenance and Update Frequency: asNeeded

Statement: AMB2014 is the third iteration of the Australian Maritime Boundary dataset, a dataset designed to provide advice on the limits of Australian maritime jurisdiction. This version is designed differently from the previous two, with a focus on ease of maintenance, a modular concept, fewer but more pertinent attributes, and suitability for an automated system. Additionally, this will be the first version of AMB to be released in GML format. The AMB dataset consists of a series of points, lines and polygons calculated rigorously from a baseline. Whilst visually unimpressive, a considerable amount of work is required to produce these lines. AMB2014 aims to provide an improved product to users, and at the same time reduce the overhead needed to maintain the database.
