Accuracy

How accurate is this?

61 m low This 3D map reads 3,901 m at the summit; the official height is 3,962 m.

Why: a 30 m terrain model averages each cell, so a sharp summit gets rounded off. The 90 m model misses by 65 m.

Source	Summit	Difference
Official height (Wikidata)	3,962 m	—
Copernicus GLO-30 (used on this page)	3,901 m	-61 m
Copernicus GLO-90	3,897 m	-65 m
