Square references
A square reference consists of at least a brigram for large squares and additionally a
number of up to four digits depicting a sub square.
The input format is not case sensitive and may contain spaces.

Coordinates
Coordinates consist of a latitude as the first component and longitude as the second. The
components need to be separated by a comma (,).
Coordinates may be entered in any of the official formats:
- Degree/Minute/Second:
52°26'23"N, 013°30'19"W
- Degree/Decimal Minute:
52°26.383'N, 013°30.317'W
- Decimal Degree:
52.43972, -13.50528
Directions can be either entered as compass points (N E
S W or O for German "Ost") or as a leading
sign (+/-). If neither is entered, a +
leading sign will be assumed.
Any special characters (° ' ") may be
replaced by non-numerical characters like blanks, hyphens, letters or any other
character, that is not a digit. The official symbols for arcminute (′)
and arcsecond (″) are unfortunately not yet supported and will render
the coordinate impossible to parse.
