The BNF for positions is as follows:
<string> :== {<spaces>} {<sign>} <field> {<sign>} {<spaces>} {<eol>}
<field> :== <number> {t_SEP <number> {t_SEP <number>}}
| <number> t_DEG {<number> t_MIN {<number> t_SEC}}
<number> :== <digits> {t_STOP} {<digits>}
<digits> :== <digit> {<digits>}
<spaces> :== <t_SPACE> {<spaces>}
<sign> :== t_POS | t_NEG
where the terminal symbols are:
t_DIGIT :== "0".."9"
t_SPACE :== " " | "\t"
t_SEP :== ":" | "/" | "\"
t_STOP :== "." | ","
t_POS :== "+" | "N" | "E"
t_NEG :== "-" | t_S | "W"
t_D :== "d" | "D"
t_M :== "m" | "M"
t_S :== "s" | "S"
-------------------------
Examples:
N60.5
60:30.55N
+60:30:55.34
21:33,45123E
It works both with european , or american .
