Yes, that is how far I got. Good you went a step further.
I think there are options for expanding: because a photo is easier to share then a location plus it tells a lot about the location itself. Better then some numbers of shortened url.
Combined with compass navigation the user does not need internet (Apple, Google maps) to still be able to navigate to a location.
And why share just one photo ? Share a collection: interesting buildings in a city, or the best places with cakes (based on just the pictures of those cakes :-).
I still think a concept to think about more. Please continue.
- gohnjanotis 11y agoThanks! That's cool you tried the same thing! Cool idea about the collections. Another extension of it I also thought about is a version with some kind of node.js backend that's a little bit like Yo except whenever you and a friend have it open it points you at each other so you can find each other on foot as long as you have a decent internet connection and good GPS accuracy.
- thesimpsons1022 11y agowhy don't they need Internet?
- gohnjanotis 11y agoAs long as you already have the app and photo on your phone it just uses the compass and GPS, which are both sensors built in to the iPhone and don't require internet.
- thesimpsons1022 11y agosorry. I'm an idiot and didn't think about gps seperately from internet
- gohnjanotis 11y agoIt's a pretty good point actually! Because Airplane Mode disables GPS on the iPhone.
- michaelmior 11y agoThat's a little odd. Isn't GPS generally completely passive? That is, it should not be possible to cause any sort of interference.
- gohnjanotis 11y agoI thought it was passive, too. I've googled a little in the past and some people say it's in the same chip as the cellular radios (and the whole chip gets knocked out in Airplane Mode). Others say the amplification of signals necessary could cause interference.
- mcculley 11y agoA radio receiver often uses a signal of an intermediate frequency: http://en.wikipedia.org/wiki/Intermediate_frequency http://en.wikipedia.org/wiki/Intermediate_frequency So a receiver that would appear functionally to be passive could still conceivably cause interference.

- michaelmior 11y agoCool. Was not aware of the usage of intermediate frequencies in radio receivers. Thanks for the knowledge :)
- icebraining 11y agoPhones often use A-GPS, which includes an active component: http://en.m.wikipedia.org/wiki/Assisted_GPS http://en.m.wikipedia.org/wiki/Assisted_GPS
