A coastline vector dataset for Heard Island and McDonald Islands, created by Geoscience Australia within the Australian Maritime Boundaries Information System (AMBIS). The dataset was last updated in April 1997.
Use Cases
- Analyze coastline geometry for maritime boundary delimitation using the AMBIS-defined polygon features.
- Use as a baseline layer for studying coastal erosion or change on Heard Island over time.
- Integrate the coastline polygon with bathymetric data to model the island's continental shelf.
Strengths
- Defined within the authoritative Australian Maritime Boundaries Information System (AMBIS).
- Provides a precise digital representation of the coastline for a remote Antarctic territory.
Limitations
- The data is over 25 years old (last updated 1997) and may not reflect current coastal conditions.
- No information is available on the dataset's spatial resolution, accuracy, or the number of vertices defining the coastline.
