Location information of the GPS is embedded in the photo which I photographed by using iPhone. I installed the add-on Exif Viewer on FireFox and checked up on the location information.

The seconds are displayed in decimal after the minutes; I calculated them. latitude 35" 25.66' -> 35" 25' 39.6 longitude 139" 13.17' -> 139" 13' 10.2

By using the "Longitude Latitude Search System" from the Japanese Geographical Survey Institute, I can display the topographical map of the place.

From the photo, you can pinpoint later where you had lost your way.

Attention
If you upload a photo of your house without modification, anyone will be able to pinpoint the location of your home.
