SOFTWARE - [Photo GPS Extract]- [About Geotagging]
By default, a picture doesn't contain GPS data. You need to have a GPS - enabled camera. This is a camera with an integrated GPS module. Each time you make a photo, the geographic location is added to the photo.
Only a small amount of cameras have a build-in GPS module. There are a few solutions to overcome this problem:
As I just explained it is my preferred way to Geotag my photos by using an external GPS device. I have bought myself the Garmin Oregon 450t for this reason. It is a portable GPS unit, powered by 2 AA batteries. This unit has many options to save the tracks you have walked. The tracks are stored as files with the .GPX extension (GPS eXchange Format). My tracks usually have an logging interval of 10 seconds. This means the GPS location is recorded every 10 seconds.
You can download the track logs by connecting the GPS device to your computer. Now you have a track logfile on your computer, you can start merging the GPS information into your pictures. I use the commercial RoboGEO software [External] tool to do this:
You are done! Now all of your pictures will contain the GPS location.
You might be wondering how RoboGEO can link a picture with a location. First of all you should be aware that each photo contains the date & time of its creation. RoboGEO will read this information from all of your selected .JPG files. Then it will search the .GPX track log to see where you were at each of these times.
