Accuracy

How accurate is this?

19 m low This 3D map reads 4,033 m at the summit; the official height is 4,052 m.

Why: a 30 m terrain model averages each cell, so a sharp summit gets rounded off. The 90 m model misses by 47 m.

Source	Summit	Difference
Official height (Wikidata)	4,052 m	—
Copernicus GLO-30 (used on this page)	4,033 m	-19 m
Copernicus GLO-90	4,005 m	-47 m
