That can actually be done with sed on the Unix command line:

% sed -e "s/\\([0-9]*\\)[WS]/-\\1./g; s/[EN]/./g; s/^0*//g; s/;0*//g; 
s/-0*/-/g" < input.txt > output.txt

But do check your input data to find out whether the stuff after the 
letter is really fractions of degrees (if you find that you never have 
the digits 6-9 following one of the letters but only 0-5 then that would 
indicate you're dealing with minutes and seconds, which would render 
above conversion invalid).
