[OSM-talk] QA tool for finding nameless highways that are armchair-fixable

[Dave F]

Most roads don't have names.

Any comparison has to be done against an authoritative database or on 
ground surveying, for the area in which you're searching.

"where the name can be interpolated from neighbouring ways. This allows 
to detect and armchair-fix a (small) subset of these cases with high 
confidence. "

I have a "high confidence" interpolation, from an armchair or anywhere, 
will lead to inaccurate data being added to the OSM database.

Cheers

This allows to detect and armchair-fix a (small) subset of these cases with high confidence. The tool is tailored to minimize false-positives.
