Ditto that - it's always fun to pick up GIMP tricks.

That would be an interesting presentation.  I've been wanting to get a GPS.
A Linux friendly flavor would be smokin'.  Maybe they all are these days?

 What NAD ("reference datum") is your GPS set to?  I don't understand it
exactly, but apparently there's a couple different NADs; NAD27 and NAD83.
Mixing them throw off the reference by a few seconds (60' per second I
believe).  I think it has something to do w/trying to map a curved surface
(the earth) to a flat piece of paper.  Or it could be something else
completely...
