I didn't realize the train coordinates were what the API was for. Were these public trains? How does google have their gps coordinates and no one else does?

- AnotherGoodName 7y agoWe installed hardware on each train to monitor them. So from each moving train we received a coordinate every minute to our servers.
- BubRoss 7y agoAre you saying that you did that to switch off of google's API?
- AnotherGoodName 7y agoNo. The only part of Googles API we considered was reverse geocoding. The train data was always ours.
- BubRoss 7y agoRight... but that would mean that what you are querying google for doesn't change. The coordinates of the trains would even only be along their route. Once you have done a reverse lookup on enough points along the route, you should have a pretty dense idea of where the neighborhoods change, right? I am not sure if I'm missing some big, but it really seems like there wouldn't be an ongoing need for querying google's APIs in this case. Finding the boundaries of the neighborhoods and especially labeling stops should be easy enough to do if it would save so much money.
