I have one question. By a "constellation" of waypoints on the chart do you mean having enough waypoints so that together they make a recognizable pattern, which is easy to correlate with the same pattern on your GPS's map page? (This is probably a dumb question, but I just want to be sure I understand your meaning.)

Yes, exactly. Of course making a recognizable pattern is only one criterion for waypoint placement. They should be located so as to provide other useful information as well, such as camp sites, critical points for crossings, paths around hazards, etc. Dan Hagen *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
