I have been playing around with this application for Google maps http://scribblemaps.com/ . It allows you to draw, annotate, print text, shade areas and add images to Google Maps at any scale on a map or satellite image. There are then a whole variety of saving options. I am sure you could put this technology to good use! Here, for example, is one I made earlier...
To see it in more detail, click on the map, then select 'menu' top left. Click on 'load/import map' and enter lNKFiaIYsv . The map will then load.
