Yes, that's the game you're thinking of. I used to play it a few years ago; Los Angeles was a great place to get into it. Pokemon Go's PokeStops were initially populated using all of the Ingress portals, which were user-contributed landmarks. The Pokemon spawn points were initially populated using the XM spawn points, which were determined by where the player location traces were most concentrated. I have no idea if they've diverged or if they're still running on the same underlying data set.

It would be an interesting question if sponsored PokeStops show up in Ingress. If they don't that suggests they're different data sets now.
