Create a genetic Map from all the others

[julia90]

Is it possible to create a map, where all the previous clines are assembled?

It would be very interesting.

Like this one for example:

It's quite easy to superimpose maps, but it doesn't always look nice. Another problem is that the scale is not always the same. For rarer haplogroups for instance, I used finer scales (1-2.5% instead of 1-5%, for example), so you cannot compare based on colour intensities alone.
