 I have created a track and waypoint route along the John Muir Trail. I have found that the trail runs through section 37085272 of the California Topo map. There appears to be less topo contour and elevation detail in that section than the surrounding sections. Is it just my downloaded file? Can someone confirm?
Wow! You're Right. That's a lot of work. I'm no computer geek but wouldn't it be neat to have a tool program that you could transfer your chosen map file to from MapSource and crop and trim there before downloading to the GPS unit?

 I would like to trim map tiles in the California Topo to be more specific to my needs and improve the redraw speed of my Etrex when panning. Also it would reduce the unnecessary downloaded file size to my minimalistic Venture HC.  Is that possible in either MapSource, BaseCamp or some other way perhaps?
