I'm working on an application to read the exif georeferenced metadata of some photos.
I would like to know all the possible values of the attribute GPSMapDAtum. Do you know where to find a list with all the standard values?
It's maybe a little unclear, but from page 79 of the May 2019 revision of the EXIF spec, it looks like that can be an arbitrary string of any length:
It's also not required, only strongly recommended.

Thank you for your answer. That documentation is what I had looked at. But the definition is too broad. – ElGerar Jul 10 '19 at 5:33

2If the definition comes from the official specification how can you call it too broad? – user30184 Jul 17 '19 at 0:10

Because the number of possibilities is very high and it does not follow any standard nomenclature. You can find values like "WGS84" or "WGS-84" ... – ElGerar Aug 8 '19 at 12:09
A good place to look would be the EPSG Geodetic Parameter Registry
A search by type (using GeodeticDatum) and area (using 'world') gives 34 results:
As for 'standard' values, my Garmin GPSMAP 64s offers me the following datums list:
- Tristan Ast '68
- Viti Levu 1916
- Wake-Eniwetok
- WGS 72
- WGS 84
- Zanderij
- None
- User

Thank you very much for the information. What I'm really looking for is if there is a list of standard values. – ElGerar Jul 10 '19 at 5:37
possiblevalues, but rather likely or standard values – nmtoken Jul 10 '19 at 6:16
