A 100-meter resolution Digital Elevation Model (DEM) details the surface topography of the Antarctic Peninsula. The dataset is derived from ASTER GDEM data and was provided by the AMD_USAPDC organization. The last recorded update was in December 2009.
Use Cases
- Model ice flow and glacier dynamics using the high-resolution elevation data.
- Analyze surface roughness and slope stability for geomorphological studies.
- Calculate drainage basins and watersheds from the elevation model.
- Generate contour maps and 3D visualizations of the Antarctic Peninsula terrain.
Strengths
- 100-meter spatial resolution provides detailed terrain information.
- Covers the entire Antarctic Peninsula region.
Limitations
- Data is over a decade old, potentially missing recent topographic changes.
- Derived from satellite data which may contain artifacts or voids in challenging polar conditions.
