Altitude
Elevation
[Wikipedia] Height is measure of vertical distance, either vertical extent (how "tall" something or someone is) or vertical position (how "high" a point is). For example, "The height of that building is 50 m" or "The height of an airplane in-flight is about 10,000 m". When the term is used to describe vertical position (of, e.g., an airplane) from sea level, height is more often called altitude.[1] Furthermore, if the point is attached to the Earth (e.g., a mountain peak), then altitude (height above sea level) is called elevation.
