How to make these figures?

Dear Matlab users, I wonder whether anyone knows how to make the two figures in attachment with Matlab? Thanks into advance,

Projecting a surface plot on a map is easy. I'd imagine the tricky part is the colormap. Normally the color you see on the surface plot is described either as a scalar (e.g. 1=white and 0=black) or a set of three values (in case of RGB). The colormap is essentially one-dimensional. In these figures, the color of each coordinate is described by two values, and the colormap will therefore be one degree higher.

It's not very difficult, but I don't know if MATLAB has any default functions for this purpose. Probably you can find something on FileExchange.
