Imagine taking a trip, coming back and uploading your photos to Flickr and seeing a map of all of your photos. While the three examples I gave had varying degrees of accuracy from 5 blocks to less than one, I truly believe the Eye-Fi Explore is a fantastic piece of equipment and will work better in more populated city areas where Wi-Fi access point density is high. There are many access points within reach of the Explore from my apartment. The WPS location data from the images I took from my apartment (like in the video) were extremely accurate, down to the building. I also happened to be stuck in traffic for that image. As for the third image, that's just about spot-on and less than a block away. That also explains the second image on the highway, where there are naturally not many access points within range. That explains the first image as I had originated my journey from the location it reported. I have noticed that if the Explore cannot find any or enough access points to determine a position, it tends to use the last known position. I have a few reasons why that might be the case: 1) I drive fast, not giving the Eye-Fi Explore enough time to scan for access points, 2) the camera was inside my car, limiting Wi-Fi reception by some factor. The Eye-Fi Explore embeds location information within the image's EXIF data, which Flickr utilizes, as well as origin information, such as "Atlanta, Georgia, United States", that are used as regular tags by Flickr.Īs you can see, the results are kind of all over the place. After I got back home, the images were uploaded directly to Flickr with the Eye-Fi and I used Flickr's map view to see where it had plotted the images. I decided to take a little drive with my Nikon D80 to put the Eye-Fi Explore to the test. Is it as accurate as the 20 meters number provided by Skyhook? Even without connecting to the access point, the mere presence of that access point and others helps provide locational information.
Skyhook has a massive database of US and Canadian access points and correlated that to GPS locations. Instead it utilizes the Wi-Fi Positioning System by Skyhook Wireless, the same technology used by Apple in the first generation iPhone to provide locational data. How does the Explore's geotagging work? For one, it does not use any sort of GPS technology.
