Antarctica's Windmill Islands region is mapped in this 10-meter cell size digital elevation model. The dataset covers inshore and offshore islands, peninsulas, and the lower slopes of the icecap leading to Law Dome. It was produced by the Australian Antarctic Data Centre and published in August 1999.
Use Cases
- Model ice flow and meltwater drainage from the Law Dome icecap using elevation and slope data.
- Analyze coastal erosion and isostatic adjustment by comparing elevation features of islands and peninsulas.
- Generate topographic base maps for ecological or geological field studies in the Windmill Islands.
- Calculate surface roughness and terrain characteristics for climate model parameterization.
Strengths
- High spatial resolution with a 10-meter cell size for detailed terrain analysis.
- Covers a specific, defined Antarctic region including islands, peninsulas, and icecap slopes.
Limitations
- Data is temporally stale, last updated in 1999, and may not reflect current glacial retreat or topography.
- Specific row count, column details, and file size are unknown, limiting assessment of computational requirements.
- Geographic coverage is limited to the Windmill Islands and does not represent broader Antarctic conditions.
