Okay, here's a topic I'm curious about:

Have you ever transferred GPS waypoints to a printed USGS map? I don't have a GPS unit so don't really know what format that data might be in or what software might be available to do the job, assuming access to a large-format printer.

Reason I'm asking:

As alluded to on the lurking thread, I was annoyed when my map didn't precisely reflect the trail I was on. No impact on the trip at all, but poor data is a pet peave. My soulution would be to take regular waypoints along the path and map it later for future use. I could also tag my favorite campsites, water sources, interesting features, whatever. Yes, I could mark these things out as I go, but the map this time around was off enough that I couldn't pin my location satisfactorily. Trails shift, forest roads aren't always obvious, "oh, I thought we were on THIS hill".

Most of the time the differences are negliglble, but I derive joy from precision and accuracy.

This probably disqualifies me from any futher participation in the "lurkers" thread! <img src="/forums/images/graemlins/laugh.gif" alt="" />
