Here's an editable version of the BART map, provided under Creative Commons (CC-By) license, for use in third-party apps, websites or whatever else needs a visual BART reference.
If you’ve seen our Developer License Agreement you’ll know that BART reserves trademarks and copyrighted material as a way to differentiate "official" information from all the third party apps and sites that are powered by the BART Developer Program. So although this isn’t an "official" map it should work well in practically any application. And if it doesn't, you can customize it to your heart's content. Enjoy!
