High Mountain Asia 8-Meter Digital Elevation Models from Satellite Imagery

High Mountain Asia glacier and snow regions are covered by 8-meter resolution Digital Elevation Models (DEMs). The models were generated from very-high-resolution commercial stereoscopic satellite imagery by the NSIDC_CPRD organization. The dataset was last updated in November 2016.

Use Cases

• Analyze glacier surface elevation and volume changes using the 8-meter DEM data.
• Model snow accumulation and melt patterns across the High Mountain Asia region from the elevation models.
• Assess terrain stability and geohazards by examining slope and aspect derived from the DEMs.
• Calibrate and validate coarser-resolution global DEM products with this high-resolution dataset.

Strengths

• Provides 8-meter spatial resolution, offering detailed terrain information.
• Focuses on the critical High Mountain Asia region, a major freshwater source.

Limitations

• Data recency is limited, with a last update in 2016, potentially missing recent glacial changes.
• Specific geographic extents, row counts, and validation details are not provided in the available description.
