Good ole google earth mainly and onX for mapping if needed.
A cool 'feature' of OnX is the sync'ing of real-time gps tracking between both smartphone & desktop versions...without cell service.If you're out in the woods with your smartphone, with OnX tracking enabled and your OnX desktop version is also open on a computer at home...anyone watching the desktop version will get real-time updates as to your location and movements in the field.A smartphone with an active account or phone number is also not needed to use OnX. I use an old inactive phone I wouldn't care to lose for outdoor stuff, but then, it's also the only smartphone I own because dinosaurs do still walk the earth.
