RaceResources LLC, you could use GPS coordinates for splits, as long as they are not stated as "certified". GPS coordinates are only as accurate as the instrument that measured them, combined with the instrument trying to locate them prior to the race. Consumer-grade units are normally accurate to within +/- 10', and some are less accurate. Descriptions from landmarks are best.

That said, if there is no describable landmark nearby, I do say "use GPS coordinates to get close, then look for marker". Usually marked with washer/nail, or surveyor whiskers.

Don't use only GPS coordinates for Start, Finish, or Turnaround locations, though. Those must have a reference to at least one landmark.
