Fotos are already timestamped, both in EXIF (together with GeoCode), and in
the file itself. That should give you enough data for setting the foto in
the time axis of a 4D map. Until Alt calculations from GPS/GNSS/[insert
future navigation system here] becomes accurate this is just an utopia.
Future GeoCode will contain planet referances, the timestamp will change to
the chosen time format in the future. All you are asking for is in the
future. Now, any special purpose maps will need to find their way of sorting
general purpose tags in addition to its own prefixed tags (or even include
prefixed tags from other special purpose maps).
