Struggling to keep control of your growing collection of digital photos? Breathe easy — you're not alone.

With digital cameras making it easy to take images of just about every aspect of daily life, budding photographers are left wrestling with the best way of labelling them so they can be saved and shared with friends and family.

While file names, key words and captions can help with the process, a new technique promises to change the way photos are stored and viewed — it's called geotagging.

As the term suggests, geotagging involves attaching tags to digital photos that describe exactly where they were taken. It's a simple concept, but it opens up an exciting range of new ways in which such tagged photos can be used.



How geotagging works
Geotagging involves finding the latitude and longitude of the place a photo was taken and embedding this information in the photo using a standard format called EXIF (Exchangeable Image Format).

Used by most digital cameras, EXIF stores everything from the time and date an image was taken to the type of camera used and its exposure settings. Geotagging just adds a little more data into the mix.

Labelling your images in this way provides another way to categorise them. Rather than trying to remember the date you took that memorable holiday to Queensland or the file names you used when downloading them, you can find your photos simply by searching for a particular location.
