When Pokémon GO first came out, I immediately thought of the need for a map of pokestops/gyms. If you know anything about the game, then you are probably aware that the only way to know for sure if a pokestop is in a particular location is to be within a few hundred meters of it (at least at the time of this post). So, what I was able to do was access their API, and using a Python script, scan large areas of Portland, and write the positions of interest to a SQL Server database. Just as I was extending this functionality to monitor Pokémon locations in real-time, access to the API was blocked. So, no more scanning… However, I still have most of my pokestop location info still saved in my personal SQL database, so I was able to map these with the assistance of Google Maps, and plot them for the world to see (although it will only be useful for those who live in or around Portland).
