Personally (and as usual 🙂 ) I think a 2d color map layer would work just fine. I’d bet you could find users who look at your map and think that the areas between the roads are ‘safe’, I assume they are just unsampled?

A possible improvement would be to produce a set of tubes over each road which are colored. This would give the advantage of making the roads stand out, give the impression that only the roads are sampled and get over the issue of ‘high air being clear’.

Do keep experimenting though!

It’s hard to see where it is, and took me quite some time to work it out. Marking key roads and the river would certainly help.
