While Pokemon Go has launched to massive mainstream appeal, it isn't perfect. The lack of any guidance or tutorial hasn't made it as accessible as it should be. However with a plethora of tips and tricks on the Internet such as this, it is becoming less of a problem. Nonetheless, those on a subreddit dedicated to Pokemon Go development have decided to take it a step further.
On figuring out how to pull data out of the game such as items at each PokeStop, Gym locations, and most importantly, where Pokemon appear, the developers have proceeded to work on a Google Map that points out the location of every Pokemon around you.
"The very first time [the map] was working properly it was like 10PM," developer Ahmed Almutawa said to The Verge. "I opened the map and there was a Dratini that was three blocks down the road. I was like, 'Nah, there's no way it's down the road from here.' But I go out, and I walk there and there's a Dratini here. I caught the Dratini my first try, so I was very proud of myself for that one."
Right now you can access this map via command line. It isn't anywhere close to being as easy as say, downloading and installing a Pokemon Go APK. It's something its developers are aware of and are trying to make more accessible. But if you're still willing to venture forth, you can try your luck here.

Keep in mind though that this is not an official project and neither does it have Niantic's approval. It's quite possible that it might block access to this information in an update.
