function latlon,vals,dirs ; ; vals contains a list of latitudes or longitudes, as strings, in degree*100 ; plus minutes, plus NSEW in dirs. The values are converted to decimal, ; with S or W given a minus sign. ; degval=fix(vals)/100 minval=vals mod 100 decval=float(degval)+float(minval)/60. neglist=where((dirs eq 'S') or (dirs eq 'W'),nneg) if nneg gt 0 then decval(neglist)=-decval(neglist) ; return,decval end
