Yeah, but once again, what's height above sea level? If I go from Mir to the South Pole, sea level is a different distance from the center of the planet. Since the world is *not* a perfect sphere, again, what do you call sea level when you've moved to a different latitude? How do I tell that (for example) the mountains of Amotrall are 10,000 units tall while those of Mir are 10,005? You can't use Trigonometry to measure height if you don't have an identical base to measure /from/!

Mean sea level is 15 miles further from the center of the Earth at the Equator than at the poles (I may be off by a factor of two here, in the case of Earth), and depending on geometry, that could be well under water at high tide. I'm assuming Celandra knows the world to be round, but that's probably not even universal.

If not, using triangles to measure the height of any feature is not guaranteed to be known. >> This message was sent through MyMail http://www.mymail.com.au ---------------------------------------------------------------- To unsubscribe, send mail to celandra-off@phoenyx.net.
