Geo-tag your photos and find them on a map – The pictures that you take with your GPS-enabled camera or smartphone and many of the images you can download from the internet contain geo-location information (geo-tags) that identify precisely where the photo was snapped (usually it's the longitude and latitude). This means that you could easily plot your images on a map, place them into Google Earth, or translate these coordinates into an identifiable location/city/country and store it in your photos’ metadata. Open source, free, software GeoTag does just that for you.
