Use Cases

Sort and find pictures

Digital photography is getting bigger and bigger – and so are photo archives. Even personal collections are often already so large, that finding your photos seems impossible, unless you are a very organized person and have a beautifully sorted archive. Luckily, the date when you take a photo is saved inside all pictures. So all you have to do is to remember when you took the photo and to browse through the photos that match that date. But more often than not, it’s hard to remember the exact time. When was the summer holiday 2003? When did we take that trip to Norway? Just imagine you could sort your files by location, just as you can sort them by date. Many times, it is much simpler to remember the place where you took a photo than when it was shot. Or take it one step further – what if you could even search by location? Well, that’s exactly what geotagging enables you to do. It adds another vital piece of data to the photo’s metadata. Metadata is data that describes the actual data. You can use this information to sort your photos or even display them on a map. This way when your’re searching for the photos from the Norway-trip, you would simply zoom in to Norway on your map and all applicable photos would show up.

Show friends and family where you travelled

Let’s say you just came back from a trip through Africa. You had a great time travelling different countries, met new people and obviously shot thousands of photos. Back home you want to share these memories with your family and friends and also, you want to show your photos to your new acquaintances from the Safari. Geotagging makes this extremely easy.

Programs like Apple’s iPhoto 09 offer a lot of support for geotagged photos. Simply choose the photos you like, drag and drop it in the photobook bar and enjoy thousands of possibilities on how you want to design your photobook. Let the program automatically create and include maps of the areas you travelled, using the GPS information from your geotagged photos. The real photobook is only a click away. Or use all this information to create a slideshow including photos and automatic maps of where you travelled to present your photos to friends.

To share your pictures with new friends from your trip, that live further away, there’s no longer the need to send around Emails with enormous data attached to it. Simply upload your geotagged photos to free online-services like flickr or Panoramio where they are automatically displayed on a map. Decide whether you want to publish them for everyone to look at or restrict viewers to your friends and familiy. Google Maps even uses photos from panoramio to show the world what it looks like somewhere else (of course only if you agree to this).

Aerial and architectual photographers

Geotagging can be of great assistance to photographers that regularly take photos of architecture, for exapmle to support a realtor. It can get confusing, as to photos of which house you’re looking at, espacially when you take pictures of several places each day. Geotag you photos and always know for sure that you didn’t get anything mixed up. This can be even more useful for aerial photographers that take pictures of whole regions, for example from a plane. GPS informations makes sure you can reconstruct at home, where exactly you were when you took each photo and your point of view relative to the subject on the photo.

Landscape and nature photographers

We’re in the Bolivian rainforest. A photographer is cowering behind a shrug very cautiously, trying not to make a sound. After hours of waiting, the rare species of Bolivian Rainforest Ants crawl out of their hill. He takes a shot and after years of researching, finally has proof that this rare species still exists. Why? The photographer used geotagging to have instant documentation of where he made this discovery. This way, he can find the exact same location anytime he wants to, for example to show his find to his colleagues.

His friend, a passionate landscape photographer, who came along on the trip, stayed behind at a small hill when he realized sundown was only minutes away. He gets some beautiful photos of the sunset but unluckily forgot that one lens that he’d really need now is in the hotel. No problem. Thanks to the GPS location data on his geotagged photos, he can find the same postition on the next day when he returns with the right lens.
