3d plot of earth with cut
Hello,
Could someone suggest a package/way to make a 3D raster plot of the Earth
(with continent boundaries), and then make a "cut" or "slice" of it such
that one can also visualize some scalar quantity as a function of the
Radius/Depth across that given slice ?
Formally, I would have a given, fixed longitude, and a list of vectors
{latitude, radius, Value}
that would show
