Geotag using phone photos gps information

I am offering an idea for automatically geotag all the photos, I.e. impute geotag for photos can’t find gps info. Since Lightroom cc has ability to access camera roll from phone, where gps information and time were recorded for each photo, we should be able to geotag the photos that don’t have geotag by simply interpolation from gps info described above. It may not be accurate, but I believe many people will found it useful.
