  GPS direction is not very accurate in slow speeds, for example walking.
  Because gps get heading information by compareing current and previous 
position and there is always little positioning error heading is not not 
accurate. Application program can of course use older position information 
to calculate heading but this indroduces delay to heading calculation.

  Afaik  Loadstone knows only intersections as points  and they have
  same name regardless the direction you are approaching that point
