Sharp elevation maps of High Mountain Asia (8 m) — HMA_DEM8m_AT

In plain English

What it measures. Sharp, 8-meter-detail elevation maps of the glacier and snow regions of High Mountain Asia, capturing the rugged shape of this mountainous terrain.

How it's made. Generated from pairs of very-high-resolution images taken at slightly different angles by commercial satellites, which together reveal the 3D shape of the land.

How & where you'd use it. Helps scientists measure mountain glaciers and snow and track how they change, important for water supplies across the region.
