Mount Yari: terrain elevation and local relief
Mount Yari uses an approximately 3,105-meter surface estimate in EGM2008 from Copernicus GLO-30. The bounded terrain section has about 1,707 meters of local relief above its lowest sampled point. Published summit surveys are separate references.

A little more perspective
Japan’s Geospatial Information Authority lists Yarigatake at 3,180 meters and supplies the summit coordinate used to center this section. The highest Copernicus sample reaches approximately 3,105 meters in EGM2008, about 25 meters horizontally from that coordinate. The conspicuous gap reflects the limits of representing a pointed summit with a roughly 30-meter surface grid; the illustration does not extend its tip to the published height.
The local-relief view subtracts the lowest sampled point in this section: 1397.7 meters at 36.310556° latitude, 137.597222° longitude. This produces about 1,707 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
