The “Gumbo Shop” is one of my favorite restaurants in New Orleans, Louisiana. A good friend used his iPhone 3GS to take a photo outside the restaurant (shown right). The iPhone features a built-in 3-MP GPS-enabled digital camera; photos taken with an iPhone are geotagged automatically. What if the photo weren’t captioned — how would you know where the Gumbo Shop is located? (For the sake of argument, let’s ignore the smaller sign that says, “Creole Cuisine,” a rather obvious clue.) The answer is, of course, inspect the photo metadata!
Click on the thumb-nailed version of the photo; a full-size, geotagged version of the photo will open in an external window. Right-click on the larger photo and save it to the desktop on your computer.
On an Apple Mac, open the photo with “Preview.” From the menubar, select “Tools / Show Inspector”; choose the “More Info Inspector” tab, then choose the “GPS” tab. Click on the button labeled “Locate” (see lower-left corner) to see the photo location displayed in Google Maps (your default Web browser will open automatically).
On a Windows PC, right-click on the file icon and select “Properties.” Choose the “Summary” tab; click the button labeled “Advanced” (in case you’re in “Simple” mode). Editor’s Note: This procedure should work; it may not. See Tech Tips, below.
Now test yourself: Is the thumb-nailed version of the photo geotagged?
Tech Tips: Download and install IrfanView, a great freeware graphic viewer for Windows. Next, download and install the Irfanview Graphic Viewer PlugIns. Open a photo file with IrfanView. From the menubar, select “Image / Information…”; click on the button labeled “EXIF info” (see lower-left corner). The “EXIF Info” window features a button labeled “Show in Google Earth” that works as expected, assuming the photo is geotagged and Google Earth is installed on your computer.
