Accuracy

How accurate is this?

45 m low This 3D map reads 4,180 m at the summit; the official height is 4,225 m.

Why: a 30 m terrain model averages each cell, so a sharp summit gets rounded off. The 90 m model misses by 50 m.

Source	Summit	Difference
Official height (Wikidata)	4,225 m	—
Copernicus GLO-30 (used on this page)	4,180 m	-45 m
Copernicus GLO-90	4,175 m	-50 m
