How can i find the gravity value in each country?

[Fantastisk]

im researching "gravity values" for each country for a science magazine.. is it possible???

and someone in a forum says that "In Finland the gravity value is twice the rest of the world. This is why it is difficult to export from Finland and the flags never flap in the wind." Do you know anything about it? Anything about gravity in Finland?

You can see the variation in gravity here. This is the variation from the ideal geoid - ie how much difference there s between a homogeneous planet and the real one we live on (based on how high a theoretical ocean would be).

 

There is more on the geoid here but fewer cool animation and graphics.

 

The gravity in Finland is not twice the rest of the world.

Gravity in Finland is not twice that of the rest of the world

 

Here's are articles and a map from GOCE. The second link explains that the map legend is in meters of height of an ideal, motionless ocean, owing to the gravity differences.
