The discussion in this thread on the Steve Jackson Games discussion board for OGRE/GEV turned to suitable city maps for the game. This reminded me that over the years, several OGRE fans have used satellite imagery to create maps of real-world locales in the game's 1500-meter-per-hex scale. Interestingly, even though most OGRE scenarios take place in Europe, these are all cities in the United States.
NOTE: In order not to bloat my file limit, I shrunk these maps before uploading them here. The originals are very high-resolution; click on the city name for links to the original files.
