Difference between 標高 and 海抜


Is there any difference at all here?

(I read one of them in a Wikipedia article and the other one in my textbook)




標高 refers specifically to the height above sea level of any point in Japan.
This height is measured with the average level of the water in Tokyo Bay as
zero. There is a stone marker in Nagata-cho, Tokyo, which is 24.39 metres
above this level and is used as the national reference point.

海抜 means the height above the average level of the adjacent sea of any point
on the planet.
