Airplane mode may also shut off the GPS positioning. If you have any pictures in a cave, they likely don’t have a GPS position for this reason. If you’re surrounded by large buildings, thick walls, or are underground, then GPS positioning probably won’t work. For the GPS positioning to work, the phone must be able to get signal from multiple GPS satellites. If you’re on WiFi, this is enough information because companies have created databases linking WiFi networks to GPS locations, by driving around and sampling signals. To find your location, the phone needs to either use the GPS positioning, or a WiFi signal. However, if the phone can’t determine your GPS location, no photos will be geotagged. Now it seems to be able to geotag without cell reception, most of the time. It used to be that if you didn’t have cell service, it would not geotag (although GPS should only rely on satellites). The iOS camera app does the best it can, and it has been improving. Nonetheless, sometimes the geotagging fails. With this enabled, every picture you take in the built in Camera app _should_ be geotagged. In the Settings app, you have to go into Privacy -> Location Services and enable Camera (it should say “While Using the App”). Of course, to enable geotagging of pictures taken by the iPhone Camera app, you have to have the correct settings. Here I’ll talk about why this may be, and how to find and fix the issue. Another, called Deep Intermodal Video Analytics (DIVA), is focused on detecting "activities" within videos, such as people acting in a manner that could be defined as "dangerous" or "suspicious"-making it possible to monitor huge volumes of surveillance video simultaneously.Now that geotags are so common, it can be upsetting to see that some pictures don’t have them when they should. Another, called Aladdin Video, seeks to extract intelligence information from social media video clips by tagging them with metadata about their content. In addition to photos, the system will pull its imagery from sources such as commercial satellite and orthogonal imagery. The goal of the program's contractors-Applied Research Associates, BAE Systems, Leidos (the company formerly known as Science Applications Incorporated), and Object Video-is a system that can identify the location of photos or video "in any outdoor terrestrial location."įinder is but one of several image processing projects underway at IARPA. The Finder program seeks to fill in the gaps in photo and video geolocation by developing technologies that build on analysts' own geolocation skills, taking in images from diverse, publicly available sources to identify elements of terrain or the visible skyline.

However, this location data is pruned off for privacy reasons when images are uploaded to some social media services, and privacy-conscious photographers (particularly those concerned about potential drone strikes) will purposely disable geotagging on their devices and social media accounts. If you have used Apple's iCloud photo store or Google Photos, you've probably created a rich map of your pattern of life through geotagged metadata. The location is stored in the Exif (Exchangable Image File Format) data of the photo itself unless geolocation services are turned off. That's precisely the goal of Finder, a research program of the Intelligence Advanced Research Projects Agency (IARPA), the Office of the Director of National Intelligence's dedicated research organization.įor many photos taken with smartphones (and with some consumer cameras), geolocation information is saved with the image by default. The ability to combine this location data with information about who appears in those photos-and any social media contacts tied to them-would make it possible for government agencies to quickly track terrorist groups posting propaganda photos. Imagine if someone could scan every image on Facebook, Twitter, and Instagram, then instantly determine where each was taken.
