View Full Version : Tracking Bikeshare Station repositioning when ID remains same

05-20-2013, 06:49 PM
Hi all,

I've noticed that some stations get repositioned by a few blocks as the system grows, while the station ID remains the same.

For my app, I need to be able to detect these changes and potentially send a notification. But there doesn't seem to be any unique field that identifies repositioning.

Has anyone found a good way to track those changes? Two possibilities:

1) Look for a name change, <name>14th & Upshur St NW</name>
2) Look for a lat/lon change, <lat>38.942016</lat><long>-77.032652</long>

Any ideas for which one of these works better, or if there's another way to track moves?
