Why are there several coordinates in place object?



I’m trying to program an application that shows a density map of tweets. Now I’m working on the place object , which (when present) indicates that the tweet is associated (but not necessarily originating from) a Place.

This link https://dev.twitter.com/overview/api/places#place_attributes displays an exemple of ONE place object for a tweet with 2 different bounding boxes for polygons and also one point (lat / long).

I’d like to know what place is publicly associated with the tweet among these three ones?

Sorry for my english, I’m not anglophone.


so it seems that the example was a juxtaposition of three place objects, I misunderstood.
Can anybody just confirm this remark?
