I am trying to create a photobook with Aperture, but their maps are highly inaccurate (lots of lakes and even the whole Caspian sea is missing!). Online maps like Google Maps or Openstreetmap work great for websites and screens, but provide low resolution (72 dpi).
Is there a simple way to generate a high DPI (e.g. 300 dpi) image for printing from these sources?
Note: I'd like to preserve the text labels on the map, so simply taking a high resolution screenshot and placing it into a small box doesn't work for me, as labels will come out tiny.
