That's a little odd. Isn't GPS generally completely passive? That is, it should not be possible to cause any sort of interference.
A radio receiver often uses a signal of an intermediate frequency: http://en.wikipedia.org/wiki/Intermediate_frequency So a receiver that would appear functionally to be passive could still conceivably cause interference.
I've been hiking and foraging for mushrooms and wild foods, so I made this simple utility app for iOS. It lets you pick a photo you took (or that someone sent you) and then points you in the direction the photo was taken, kind of like a compass, based on the coordinates stored in the photo's EXIF data. It's basically a fast and easy way to mark locations and get back to them. Originally I tried it in JavaScript, but…
Very neat idea, reminds me of the Gatherer add-on from WoW ( http://www.curse.com/addons/wow/gatherer ).
Great idea, but charging to show in feet? Ridiculous. Uninstalled.
I love the idea of charging to show in imperial units. That's some amazing pro-SI propaganda, we need more stuff like that :)
So this would not work with photos taken with a DSLR without a GPS module/attachment.
Am I correct?
I'm assuming this works with GPS data. So this would not work with photos taken with a DSLR without a GPS module/attachment. Am I correct?

Depends. You can also retroactively edit the EXIF data to reflect a location. It should work on those kinds of pictures, even though the original camera didn't have a GPS.

It uses the EXIF data, so it would use the location data in the EXIF. > So this would not work with photos taken with a DSLR without a GPS module/attachment. Depends.

I think this is so. Reading the developer's post it seems he had the idea to use pictures taken with his iPhone, which would include GPS data in the EXIF.
I think this is a fantastic idea.

Correct, I should've been been more clear in my post; I meant location data in EXIF data that has been recorded by the/a GPS module. I think this is so. Reading the developer's post it seems he had the idea to use pictures taken with his iPhone, which would include GPS data in the EXIF. I think this is a fantastic idea.
But yep it just pulls the lat and lon from the EXIF data, so it should work fine. The standard for EXIF is degrees, minutes, seconds and then a separate "Ref" value for N or S.
I have to do a little math on those values to turn everything into a decimal format, but based on this standard I would assume everything saving location in EXIF data would use this same format so it should all be compatible:

If you test it, let me know!

I don't have much experience with DSLRs and didn't even know there were GPS modules for them, but that makes sense and is awesome!

My initial thought was pulling some of my favorite shots from Flickr and using this to find the location of where the shot was taken. Great for finding those hidden photoshoot locations!
Unfortunately most DSLRs do not have the GPS built it. It's usually an add-on attachment.
