The attached map was created using GMT based on the Earth Relief data. I wonder if anyone knows how to plot it using Matlab?
Many thanks!

If you have access tio GMT, it may be more convenient making the map in GMT. Otherwise, the Mapping toolbox may be your best bet for a quick fix to your problem.
However, if you have the time, find the right projection, create the code to generate an X an Y array from the Lat-Lot data. If you interpolates to a regular grid, you may use imagesc to create the topographic grid. however, you can get a preview using mesh.
Next draw geodetic grid on top, if required.
You can find geodetic to UTM and back packages on the Matlab Central.
Good luck, Morten

Ran in:
Do you want to replicate that plot exactly, or just the general concept? If the former, I'd recommend looking at m_map, since it allows for a similar map border style, colormaps, etc. With the Mapping Toolbox, you should be able to get a close replica, though:
worldmap('north america')
geoshow('landareas.shp', 'facecolor', 'none')
Both m_map and the Mapping toolbox include a variety of options for plotting projected raster data, but you'll have to download the desired terrain data prior to that.
