![]() The answer to the question “Where is Kochkor, Kyrgyzstan?” becomes an experience rather than a one-dimensional text description. However, we’ve traveled to some places that are unfamiliar to many (even some geography majors). We also use our photos to help us tell a story about our experiences. If we use a GPS device and some freely available software, we can batch process and associate our photos with detailed location data (within about 50 meters). Geotagging our photos is a critical step in accurately documenting our journey. In the context of extended travel, the process of manually associating accurate location data with each photo becomes a colossal nightmare. While we do take notes, we sometimes miss the name of a village or mountain. Murghab, Kyrgyzstan.Ī valid question perhaps, but considering that over the course of this journey we are using two cameras and taking 1000s of photographs across dozens of locations, this is not a practical option. “Why not jot this down on a piece of paper somewhere?” you might ask. Embed the matching location data in the EXIF data of your photos.Īs a matter of practicality, we’d like to know where each of our photos was taken.Based on time stamps, match your photos with the location data logged by your GPS device.Collect digital location data (latitude/longitude/time coordinates) using a GPS device.You can find a sample of EXIF data on the right-hand side of one our individual photo pages, under the “Photo Tags” section. EXIF is the data in a digital photo file that describes things like the kind of digital camera used to take the photo, the date and time when the photo was taken and the conditions under which the photo was taken (including shutter speed, aperture, etc.). What do you mean when you say a photo is “geotagged”?Ī digital photo is geotagged when location data (latitude and longitude coordinates) are added to the digital file alongside the photo’s existing EXIF data. To remain current, we will refer to the device as Sony GPS-CS1KA, the updated (yet functionally and technically similar) model. Part 3 covers how to upload your geotagged photos using PictureSync and what you can do with a geotagged photo, including using Google Maps to interactively display where the photo was taken.Ī note on naming conventions: We actually use an earlier model of Sony's GPS device, the Sony GPS-CS1.We will discuss the hardware and all the various software (Sony GPS Image Tracker, GPSBabel, and GPSPhotoLinker) that we use to efficiently geotag large groups of photos. Part 2 addresses the technical nuts and bolts of taking geolocation data from the Sony GPS-CS1 ( Sony GPS-CS1KA) and embedding it into the EXIF data of a photo.This section is for readers new to the concept of geotagging. Part 1 (this article) is intended to explain what geotagging is, why you might consider doing it, and which GPS device we use, the Sony GPS-CS1 ( Sony GPS-CS1KA).We thought a case study on geotagging would be useful for fellow photographers, travelers and technology geeks alike. How did you get those maps at the bottom of your photo pages to work like that?.The conversation often begins with “ What's that device with the blinking light hanging from your camera bag?” The questions continue: We are frequently queried about our photography and the topic of geotagging. We’re going to tell you in a three-part series – starting now. 15 Months, 16 countries, and 1000s of photos taken on the road – from boats, trains and buses, and on horseback – all of them geotagged and many displayed with GoogleMaps.
