Hi David:

Thanks for pointing me to the "updated" version with CountryData and
GeodesyData features. Nonetheless, my problem still remains. I wish to
use GMT datasets in Mathematica. For example, how would I plot a
detailed map of California with the San Andreas faults with a
distribution of gravity changes after an earthquake? Okay, so a little
specific. But, GMT has high resolution coastline data and for some
countries, state/province boundaries. Further, there exists in the
scientific community a wealth of other datasets that contain fault
maps for almost every region of the world.

As far as I can tell, the GeodesyData and Country provides *only*
macro-facts. Country size, geo-location of my computer, etc. I see how
the spherical projection functions and calculations will be of great
use. What I would like to do is reproduce similar figures  as are
shown here (look at any on the right hand side):

Or look at any of the "map" links here:

Further, I would like to do so using Mathematica. If GMT (freely
available) already has the datasets with the proper coordinates, I
want to find a way to import that data into Mathematica and create
similar images.

I was hoping someone else had similar experience with GMT and
Mathematica, or at least, an alternative way to reproduce similar
images. CountryData and GeodesyData as of yet, do not have that
capability from what I can tell.

Cheers,

t.
