Ep!

where is the zero point of "sea level" (gps coordinates) ????

in what sea/ocean ????

in what point ???

how is measured altitude of mountains ?

how mach meters have the Gaorisankar (Everest) ???
some people say 8.848 others 8.850... what is correct ???

Dead sea is at "sea level" ???

the big depression in water surface in Indic ocean of -300m. is also at "sea
level" ??

after indic tsunami and global changes in planet "sea level" also sufer
variations ???

That depends on how you set the datum. Look in the menus of your GPS
machine and see which datum sets are available, then Google up the
references to see which is most appropriate for your usage & area.

in what sea/ocean ????


Varies widely, "mean sea level" for specific areas is defined by
averaging out the tidal variation over a 19 year cycle.



how is measured altitude of mountains ?

With a very very long piece of string.

DSK

Sea level is at your waterline.

Your welcome.

I think the reference is not a point but a surface, the geoid surface, which
is an oblate spheroid that is determined I think by measuring the gravity (I
don't know how, thpough). This gives 0 meter altitude.

Actually the Chinese are just sending a mission to determine the new height
of the Everest, since it is believed that Everest snow cap is melting down
due to global warming.


Dead sea is at "sea level" ???
Dead sea is approx 400m below sea level.

the big depression in water surface in Indic ocean of -300m. is also at

I didn't know that. Where did you find that ?

Actually, parts of sumatra shore ahev dived under water, beacuse the
earthquake have lowered part of the island. The variation of sea level was
but transient, as far as I know.

Doncs si home, a reveure ! Que vagi be a Catalunya ! Coneixes-tu foros de
geología en castellá o en catalá ? En vaig buscar pero no vaig trobar rés.

According to Jon, global warming is Bush's fault.

He fail to see that global warming and cooling has been a cycle going
on since the beginning of the earth.

Enjoy the warm winter days, and buy waterfront land inland now while
it's still cheap.

According to the Republicans, global warming is a hoax.

You were the one wearing a jacket in the BVI's Ganz...... what's up wid

No. Global warming is not Bu****'s fault. He's just making it worse.

Yo,

Yo man. Mean sea level is almost an arbitrary point. It's picked for a best
fit of data. Mount Everest is not the tallest mountain when measured from
the center of the earth. Chimborazo in Ecuador is. The ocean has depressions
in it all over the place. Gravity is not the same over the earth's surface.
The world standard for sea level and the gravitational constant is located
here on Gilligans Island 10 meters from the stern of the Minnow, right next
to the Captain Neal shrine. The Professor keeps it calibrated on a daily
basis.
Hope this helps.
