<div>I read an article that said that the police have used the
GPS info in photos to find people that have a social media
account, but are "missing". Teens that ran away, etc Once
they know where the photo was taken, they have the state and
county to start looking for that person. I guess that it could
also be used in a legal case. What if someone had video or
pictures that prove something, but when you extract the GPS
info, turns out that the event was several miles away from
what the person claimed. Fraud and perjury. And they are
busted. I guess that there are other uses too, I just can't
think of any.</div>

the topic of GPS coordinates: what use case can you think of
for this? <br>
I've been aware of geotagging (an dother EXIF data) in photos
and videos <br>
for years, and have written code to extract that data from the
files, but <br>
have not come up with many use cases. Ideas?<br>
