![]() Converting tracks for use with GPSPhotoLinker My desire is simply to sync the geo data with the photos and then get on with the rest of my workflow. There are many different geotagging applications on the market here are a few for OS X compared but I’ve settled on using GPSPhotoLinker because I don’t need some of the extra features like tagging via drag+drop or looking at images on maps. Other GPS devices like those from Garmin will work much the same way as described above - just follow the manual’s instructions on recording the tracks and downloading them to your computer. Unfortunately, it writes logs are in a custom format that have to be uploaded to their web site and then exported into a variety of formats. Like the dedicated Sony device, while the application is running it records a log of points that can be transfered to your computer later via USB. The 3rd party location recording application I’ve found is called GPSed. The Nokia N95 is a higher end cell phone with built in GPS and the ability to install applications. While its on it will record a log file containing points every 15seconds in a format called “ NMEA sentences”. To start recording a track you just turn it on and to stop you turn it off. ![]() The Sony GPS-CS1 is a device made specifically for logging GPS points for use in geotagging and attaches to your computer via USB. ![]() Here I’ll explain how I use GPSPhotoLinker on OS X to batch tag many photos from a day’s photo shoot with GPS tracks recorded on either a Sony GPS-CS1 or a Nokia N95 cell phone in order to create mapped photo galleries, like this one on Flickr. And photos taken with any digital camera can be tagged in this manner. Any device that can record a “ GPS track” that can be transfered to your computer can be used to tag photos. However you can still geotag your photographs accurately and automatically with the use of an external GPS enabled device like a cell phone, navigation device, or a dedicated GPS logger. While some cameras and camera phones have the ability to geotag digital photos as they’re taken, most still don’t. Update : I’ve written a new post about my current workflow for geotagging photos based on information from my iPhone
