Hi,

I've seen that is used the format "+-DDMM+-DDDMM" or "+-DDMMSS+-DDDMMSS"
to represent latitude and longitude according to ISO-6709 [1] standard.

1) But, the standard is used whith decimals:
±DDMM.MMM ±DDDMM.MMM (degrees and minutes)
±DDMMSS.SS ±DDDMMSS.SS (degrees, minutes and seconds)

2) Could your database to use one only way to represent the format? Or
degrees and minutes; or degrees, minutes and seconds. So, the
coordinates could be stored as float in the data bases, since that we
know its total length.

Greetings!
