A digital elevation model (DEM) of the Austfonna ice cap surface was created by combining SAR interferometry with ICESat laser altimetry. The dataset was produced by the SCIOPS organization and was last updated in 2008.
Use Cases
- Analyze surface elevation changes over time using the DEM's height field.
- Model ice flow dynamics by correlating surface slope features derived from the DEM with velocity data.
- Calibrate or validate other satellite altimetry products using the ICESat-derived elevation points.
- Study the spatial structure of surface features like crevasses or melt ponds from the high-resolution interferometric data.
Strengths
- Integrates two complementary satellite measurement techniques: InSAR for spatial detail and ICESat for vertical accuracy.
- Focuses on the Austfonna ice cap, a key component of the Svalbard archipelago ice cover.
Limitations
- The dataset's last update was in 2008, making it temporally stale for analyzing recent changes.
- Specific technical details like spatial resolution, vertical accuracy, and row/column counts are unknown.
