Geotagging is when using digital cameras .You put the GPS location into the image data.No worries the photo is still the photo.But when you have "taged " the photo the gps data stays with the photo.I am sure we have all or most of us looked at photos taged to a loaction on Google Earth?Well this is a way to do that with much less skull sweat.I read that there are many different ways to do this.I am just getting started in this adventure myself.
