I imported the maps into my oregon and the overlay location over the BaseCamp/Topo US maps were spot on.
Of the three maps the Elkmont map seemed to hold its resolution the best as I zoomed in but still fuzzy as I work in closer before my Topo US Maps take over as the primary view. At about where my screen allows for a 1000' feet, maybe 1200-1500' is where the resolution starts to drop the view quality. Wish I could figure that out. But regardless, these are alot better than any custom map I can come up with and any of the others I have seen.
Hope this is worthwhile feedback.
