[Cdt-l] Jonathan's GPS map datum

[Eric Whte]

I noticed this summer that my latitudes matched exactly with Jonathan's maps, but the longitudes did NOT. They were off by a little. I assume he is using another map datum - different from the default selection on my GPS 60CSX. Can some (maybe even Jonathan himself) tell me what position format and/or map datum is used on his maps? Thanks. Eric White
