I dug up two unfinished plans from 2 years ago, when we we contemplating riding from Incheon to Busan. It may convey the idea.

On the left, a screen capture from bRouter. On the right, a topological rendering generated with Google Sheet. These simplified maps could be used as an index for a more comprehensive travel kit - click on a segment to go to the larger scale and perhaps additional material.

[WRT keeping a Kindle screen on -- quick test suggests that preventing sleep drains the battery at the rate of 10% / day, vs probable 1% / day for a sleeping device, so I think I'll stick to hitting the power button and wait 2 seconds for the display to come on. Onyx BOOX allow you to customize the lockscreen. Too bad the Kindle doesn't.
