Gravity map of the earth

[Ivan Seeking]

"These gravity anomalies, as they are known, are imperceptible to the human senses, and so the scientists have wrapped the data on to a sphere and exaggerated the highs and lows."

Wow, that's good, but wouldn't it be great if they put a color legend so that we know how much change in gravity does the colors mean ? (and therefore, it will turn out usefull ).
Also (as soon as we have a color legend), we can make sure it is right, cause ... the difference of gravity between the poles and center of Earth should be easy to see in this kind of maps, shouldn't it ? (cause i don't see it !)
