Mount Aso: terrain elevation and local relief
Mount Aso uses an approximately 1,588-meter surface estimate in EGM2008 from Copernicus GLO-30. The bounded terrain section has about 970 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 Aso’s Takadake at 1,592 meters and Nakadake at 1,506 meters. This section is centered on Takadake, with a maximum Copernicus sample of approximately 1,588 meters in EGM2008. The selected maximum is not the floor of Nakadake’s crater, and the bounded section does not encompass Aso’s entire caldera. Neutral shading carries no claim about current volcanic activity.
The local-relief view subtracts the lowest sampled point in this section: 618.1 meters at 32.915833° latitude, 131.106389° longitude. This produces about 970 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
Mount Aso uses an approximately 1,588-meter surface estimate in EGM2008 from Copernicus GLO-30. The bounded terrain section has about 970 meters of local relief above its lowest sampled point. Published summit surveys are separate references.

Takadake supplies the selected summit reference. Its 1,592-meter published elevation is separate from Nakadake and from the approximately 1,588-meter modeled maximum.
