These are my maps of Grand Theft Auto: San Andreas. The base imagery comes from approximately five-thousand aerial screencaps from Steve M's Map Viewer software that were then meticulously stitched together using both scripts and a lot of manual work. Data layers were mostly plotted from the game data itself, so the information is generally pretty accurate.
All images are at 1-meter resolution. The entire map is 6,000 meters on a side (over 3.7 miles).
