Accuracy

How accurate is this?

17 m low This 3D map reads 621 m at the summit; the official height is 638 m.

Why: a 30 m terrain model averages each cell, so a sharp summit gets rounded off. The 90 m model misses by 31 m.

Official height (Wikidata)	638 m	—
Copernicus GLO-30 (used on this page)	621 m	-17 m
