I talked about my passion for maps in a recent 'Pour Vous' post on my web site. Remember when you were in meetings - and the 'winner' was the one who had the marker ? Turns out there is another race - who owns 'the map'.
Fascinating comparison of Google Maps versus Apple Maps.
Seperately of course - there is the whole other issue around how global maps need to reflect the truth [PDF] - not the perspective of the cartographer. An obvious example is that of Kashmir, which is but one of hundreds of border debates raging around the world.
