So I'm traveling soon, to a part of Crimea that I dont know, and I'm looking at this girl's geo-tagged photos of some really nice beach I'd like to visit, estimating how far, & how I'd bike there, etc.
Then I notice she has some other geo-tagged pictures (17), of a spot I've seen with my own eyes... I look that the geo-tagged Google map, and the tag is sited more than eight miles NW from where I KNOW that picture was taken. Dont know much about GPS, but its supposed to be very accurate, to within metres, no? Clearly, these geo-tagged photos are NOT, they're waaaaay off.
Is this a tech or human input error? Is this a common or extraordinary mis-coordination? Because she geo-catching on a stone mountain? Cheap GPS? Would the presence of a formerly top-secret Soviet military facility extremely close by be a mitigating factor somehow? And most importantly, does this simply mean that all her pictures' geo-tags are highly dubious & totally unreliable?
My point: I really dont want to hunt for that beach, six miles off track! Kinda defeats the whole purpose of GPS, no? I'd post links to her landscape pictures & Google maps to illustrate my point but that might seem invasive. She's not a Thorntree poster anyway, and though I suspect her English is severely limited.
Just a curiosity - thanks !
As I understand it, some folk use pocket GPS loggers to record their tracks, then they merge the location data with the photographs. However, it requires that the camera time is set accurately, if it isn't then the locations will be out of whack...
That said there are also a few folk out there plagiarising other people's photographs, and then making up all manner of stuff about "their" images to make them look authentic.
Prior to GPS there was Sat Nav. Had one on my boat.
One time it told me that I was about three miles inland from where I was anchored in Mexico.
Another time it informed me that I was in central Africa. I thought that I was in Costa Rica.
Came as quite a surprise.
I must have taken a wrong turn somewhere.
And made very good time....
