Better Geotagging, revisited

Flickr-map_zoom-1x

In a recent blog post, I shared a simple tech tip for better geotags in iPhone photographs: Launch the Maps app and verify your location BEFORE taking pictures with the Camera app. I should follow my advice! Huh? Look at the Flickr Map (shown above) of my photo gallery, “April showers bring May flowers.” All of the photos in the gallery should be located on three streets in Hollin Hills (listed in chronological order along my photowalk): Elba Road; Nordok Place; and Mason Hill Drive. As you can see by looking at the map, there are several outliers that are not located (geotagged) correctly. Question is, what caused the photos to be geotagged incorrectly?

Apple iPhone is the best all-in-one device for geotagging photographs, as I explained in “The ABCs of A-GPS.” iPhone “Location Services,” as good as it is, can be surprisingly inaccurate after an iPhone has been either in sleep mode or powered-off. It was raining lightly during most of my photowalk through Hollin Hills on Sunday: When I stopped to take photos, I was in a rush to prevent water damage to my iPhone and did not use the Maps app to verify my location before shooting pictures; my iPhone was in sleep mode between stops along the photowalk. Net results: My iPhone wasn’t damaged (that’s good news); several photos were geotagged incorrectly (that’s bad news). Perhaps I could have avoided the problem by running a GPS-tracking app in the background, such as MotionX GPS. Point is, you can’t assume an iPhone will correctly geolocate every photograph you take with its built-in camera, but you can get better results by using the Maps app to get an accurate position fix before taking photos.

Finally, a quick word about the Flickr photo sharing service. Is it just me, or is the Flickr user interface often less than intuitive? I was sure I set up my Flickr account to enable sharing photo location information. Turns out I was wrong. I discovered the solution after troubleshooting the problem. Sign in to Flickr. Click on the hyperlink labeled, “Your account.” See the section entitled, “Defaults for new uploads”; for the setting, “Import EXIF location data,” select “Yes.”
