World map (high resolution, land areas)

This is a high resolution world map of land areas from one of Matlab's world map examples. I extracted the lines from this image into Inkscape, then made a vector graph, then extruded it. I deleted most of the small islands and unfortunately the continent of Antarctica as the line extraction gave too many breakpoints to yield a succesful extrusion. (It should be the Robinson projection.)

Here's the lazy code I wrote to extract land pieces.

I = geoshow('landareas.shp');

X = [];
Y = [];
for k = 1 : numel(I.Children)
disp(k)
x = get(I.Children(k), 'XData');
y = get(I.Children(k), 'YData');

X = [X; nan; x];
Y = [Y; nan; y];
end

X(1) = [];
Y(1) = [];
