If you had access to the twitter feed (and I did at one point, as our company got the firehose from Twitter), it showed the Lat/Long of where it was posted from IIRC.
I still remember looking at that tweet when the helos went in for OBL, from someone in Abottabad PK, saying something like "helicopters hovering at 2AM... this is a rare occurrence" (or something like that).
It's still there, they just stopped showing it in the UI. If you poke about in the React state of the Twitter UI, you can see it in the `tweets` entity cache (everything else is still Twitter under the hood too).
The old Twitter and its API had "source" field which showed the client app a tweet was sent from.
