I don't know exactly what you need to do with this, but my first 
instinct would be to use a GIS like MapInfo to make the world map itself 
and then use something like GD to draw on anything you need on it, once 
you take the geographical coordinates and convert it to where you want 
it to be in pixels then it shouldn't be so hard.
