IPA: /hɪpˈsɒmɪtɪk/
KK: /hɪpˈsɒmɪtɪk/
Relating to the measurement of elevation or height, especially in relation to sea level.
The hypsometric map shows the different elevations of the land.
Hypsometric is formed from "hypsos" (ὕψος) (meaning height) and "metron" (μέτρον) (meaning measure). The word refers to the measurement of height or elevation, particularly in relation to geographical features.
Think of 'height' ('hypsos') being measured ('metron') — that's what hypsometric means.
