Definition
海拔 (hǎi bá) specifically refers to altitude or elevation measured from sea level — it's the height above sea level. 高度 (gāo dù) is a broader word for any height or altitude, not necessarily relative to sea level. 海面 (hǎi miàn) means 'sea surface' or 'sea level' as the reference point, not the elevation itself.
