Hello,
Every time i try to do a historical map i find it hard to find a good base map to work on. Yesterday i found this web site where you can use Google maps images.
Photoshop overlay for Google Maps

Site is really good and useful but doesnt work for me because in order to see smaller rivers and settlements you need to zoom a lot thus making the map image very small scale and i have no time taking few images and putting them together as a puzzle.
Does anyone know any other way to get good HD real world regional maps (specifically Drina river - Balkans) on Google maps or somewhere else?

Thanks
