17637	Improve resolution of length measurement	stanton	team	"== Use cases

Some use cases (particularly underground mapping, where distance from a known point is the only reference) require precise length measurements. Currently, resolution of the distance shown in the status bar is 1 m for distances less than 1 km; after that the resolution changes to 0.1 km. The latter is insufficient for many mapping purposes, and since in longer tunnels the nearest reference point is often more than 1000 m away, the current behavior limits mapping here. Getting meter resolution at distances beyond 1000 m currently requires a cumbersome workaround.

== Desired behavior

A simple but workable approach would be to keep resolution at 4 significant digits, but no more granular than 1 m. For example:

* 3 m
* 42 m
* 541 m
* 1.304 km
* 10.39 km
* 500.8 km

That would still limit resolution to 10 m in longer tunnels (beyond 10 km), but that is still 10 times the resolution we have now.

== Benefits of the solution

Improved mapping where GPS cannot be used.

== Possible drawbacks
