Its surface is 256 times larger than current Earth's landmass.
Interestingly, the size of this world is now bigger than the surface area of Minecraft up to its usable limit (~30,000km until you hit precision problems).
"... Because Jupiter is made of gas, mostly, its surface is considered uniform. As such, it lacks high and low points — mountains and valleys — such as those found on rocky terrestrial planets." - Dont think the height-data would be too much complicated (aside that he´s a oblate spheroid - broather in the equator, thinner from pole to pole), maybe even a 1km resolution would be enough.
But if ya ewer make Jupiter, do let us go into the storm atmosphere ... i just like to fly there.
... pff, first man on Mars ... ill be the first on Jupiter
