I like to make up my own interesting international routes on my longer trips rather than always following conventional routes.
But often it's tricky to plan a route in lesser-known parts of the world due to the changing relationships between neighbouring countries whose borders may vacillate between open and closed with the passing years and decades.
This might only be a concern when thinking about a trip across a large swathe of the world, such as Western Europe to East Asia overland.
Does anybody know of an online zoomable map, perhaps based on Google Maps or OpenStreetMap or such, that clearly features indication of the status of each border. Colour-coding would be the obvious way with green meaning open, red meaning closed, and some colour meaning "open only to residents of these two countries", which seems pretty common.
Obviously some borders are open or closed to various nationalities etc, but this is not going to be easy to include in such a map so it's not what I'm looking for.
As a bonus, a map showing each official crossing point just as clearly would be extremely useful.
