Put Your Photography on the Map (Literally)
Goal: Learn how to Geotags your photos and place them on a map quickly and easily using free software.
Geotagging is the process of adding geographical identification metadata (information about a file) to photos (and other media). This allows applications and web pages to identify and display where an image was taken. You can use Flickr and other services to place your photos on a map that shows their locations.
Where does the Geotag Data Reside?
The longitude and latitude information is placed inside the Exif data (data that identifies date, time, and camera settings, among other things) of an image.
That’s great, but how do you find and add the GPS coordinates to the Exif data in an image? It sounds pretty complicated and technical. Well, actually you can do it yourself in just a few simple and fun steps. The best part is, you probably already have and use the software that you’ll need.
