A 1:300,000 scale map depicts maritime boundaries and zones in the Torres Strait. The map shows jurisdictional boundaries, a seabed and fisheries line, and a protected zone established under the 1985 Australia-Papua New Guinea Treaty. Geoscience Australia maintains the underlying data via the Australian Marine Spatial Information System.
Use Cases
- Analyze jurisdictional maritime boundaries based on the territorial sea baseline and outer limits.
- Study the extent of the protected zone established for traditional inhabitants and environmental preservation.
- Map the seabed and fisheries jurisdiction line defined by the bilateral treaty.
Strengths
- Map has a defined scale of 1:300,000 and a specific projection (Mercator).
- Spatial coverage is precisely defined from 9S to 11S and 141 15E to 144 30E.
- Data sources are cited, including the Australian Marine Spatial Information System (AMSIS) and the Seas and Submerged Lands Act 1973.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
