I recently learned that most common smart phones do something called geotagging. As people who regularly follow this site will know I have recently been doing a lot of work with a new HTC Evo so I was really interested in this. Geotagging, also called geocoding, is the process of assigning geographic location metadata to a photo. The geographic information can include details such as the latitude and longitude coordinates or city and state details for the geographic location of the photo. I may write a later article on how to actually extract the metadata from a picture however for this post I will just show how to turn it off.
