Projection Help GPS vs National Atlas

[Ed McNierney]

James -

Could you explain what you mean by "stored first in the shapefile"?
Shapefile coordinates are unitless X and Y numbers - longitude is an X
coordinate, and latitude is a Y coordinate (at least if you pretend the
Earth is flat).

You're free to use "proj=longlat" if you find that easier.

Ok, I figured this one out.  It wasn't a projection problem, it turns
out that even though the projection is latlong the long needs to be
stored first in the shapefile.  Go figure.

Thanks for the help.
