Changtse: terrain elevation and local relief
Changtse uses an approximately 7,488-meter surface estimate in EGM2008 from Copernicus GLO-30. The bounded terrain section has about 2,137 meters of local relief above its lowest sampled point. Published summit surveys are separate references.

A little more perspective
The 2010 American Alpine Journal account Free Mountaineering gives Changtse as 7,543 meters. Eduard Geyer’s 1983 expedition report uses 7,550 meters; these dated published references are not averaged. The bounded Copernicus surface reaches approximately 7,488 meters in EGM2008. Its southern extent excludes Everest, which supplied the maximum in the initial wider window. This surface therefore represents the selected Changtse area, with its own sampled base.
The local-relief view subtracts the lowest sampled point in this section: 5351.1 meters at 28.074722° latitude, 86.866389° longitude. This produces about 2,137 meters of relief within the stated boundary. It is not a universal mountain base, a route’s total ascent, or topographic prominence.
The rendered surface uses the public 2021 Copernicus release, primarily based on TanDEM-X observations from 2011–2015 with infill from other sources. It is a surface model rather than a current bare-earth survey. Neutral shading explains the geometry without claiming a snow season or photographic ground texture. No datum conversion or summit correction is applied.
Quick facts
Changtse uses an approximately 7,488-meter surface estimate in EGM2008 from Copernicus GLO-30. The bounded terrain section has about 2,137 meters of local relief above its lowest sampled point. Published summit surveys are separate references.
