Australia's Timor Sea Maritime Boundaries Map 2019

Map data depicts Australia's maritime jurisdiction zones in the Timor Sea, including the continental shelf and territorial sea baselines. The map was updated in December 2019 by the Australian Ocean Data Network to incorporate changes from the 2018 Australia-Timor-Leste Maritime Boundaries Treaty. It is one of 27 constituent maps in the 'Australia's Maritime Jurisdiction Map Series'.

Use Cases

• Visualize the outer limits of Australia's maritime zones, such as the continental shelf, using the provided geospatial boundaries.
• Analyze changes in jurisdiction by comparing the 2019 treaty-based boundaries with previous limits from the 2014 or 2012 proclamations.
• Overlay the jurisdictional boundaries on the included background bathymetric imagery derived from GA 2009 and Smith and Sandwell 1997 grids.
• Study the relationship between the proclaimed maritime zones and the background land imagery sourced from NASA's Blue Marble.

Strengths

• Updated in December 2019 to reflect a major 2018 international treaty.
• Integrates bathymetric data from two specific sources: the 2009 9 arc second grid by GA and a grid by Smith and Sandwell, 1997.
• Part of a standardized series of 27 maps covering Australia's maritime jurisdiction.

Limitations

• The map is described as 'indicative only' and not a definitive legal source, with some limits subject to change.
• Specific data formats (HTML, PDF) are not machine-readable geospatial formats like Shapefile or GeoJSON, limiting direct analysis.
• No quantitative metadata (row count, file size) is available to assess data volume.
