I have not seen a clear answer for this one. My interpretation is that is
should
be stored in DMS, for example 10°30' would need to be stored as 10.3 (and not
10.5 as it would be in decimal degrees). And 10°30'20" would be 10.3020.Or
maybe
the first case would be 103000 and the second case 103020 (the unit scale
suggests that - I would need to check the code and the EPSG definition for
making sure).
However I'm not aware of anyone doing that - I think that most peoples handle
that as decimal degrees. I'm not sure what GeoTools does (I would need to check
back to code), but I guess that it would need to be controlled by Hints.
The handling of real DMS units in GeoTools is partial. There is a begining of
real support of it, but most attempt to transform a coordinate using such CRS
will fail with a FactoryException for now.
