Photos recorded using an iPhone or iPad have geo-location information embedded in each photo’s meta-data if Location is turned on when taking a photo. Howver, this data is generally not immediately accessible by a friend simply viewing your photos in, for example, a Facebook album. A recently released free app can help expose this information to your friends.
Photospots (iTunes App Store)
Photospots lets you mark the spot on a map where a photo was taken and then share it via email or to Facebook. The result is an image combining the photo with a map view of where the photo was recorded and text information which includes an approximate address and a time-date stamp. This seems like a good way to provide when, where and what for each photo you share from an iPhone or iPad.
