The idea is very simple: we have to take a picture of the Moon limb (the same place) at the same time (UTC) from far places on Earth.
We want to combine the images to get a 3D view of details.
For example: let's suppose that we have two observers, one in Venice (Italy) and the other in CapeTown (South Africa).
Difference in latitude:
which is more than a couple of moon diameters
This angle is equivalent to see an object with our eyes (7cm) at a distance of:
We can use the images both with a 3D viewer for Virtual Reality or, after computer processing, generating 3D navigable landscape.
