When using photo's without GPS-info (like from a DSLR) in a 3D triangulation, you sometimes need tiepoints to get these photo's connected to your model. If your model then is geolocated, is possible for CC to edit the photo's exifdata with this geo information? So when using these photo's in a new model, these are geolocated. And when adding the photo's in a database with a map, the photo's are displayed at the right location (works like Geosetter/Exif tool)
