"Make a change, wait a day, see if I get a dozen osmose errors" is a bit slow with low turnaround
@AbbieNormal OK, that looks helpful in a way. Do you know how to get that to display “routing islands”?
I guess you just let it show the translucid graph and you look for islands in the outlook
Dark ares will be isolated
Bright areas with dark spaces in between could be isolated from each other
It' s still a quite manual work 😕
@AbbieNormal Well it seems to show a sort of routing graph, but alas it colours it all the same, so I can't see any islands...
@AbbieNormal I discovered in JOSM you can "select all connected ways". So you can find island by selecting a big road, then Ctrl-Shift-E to get connected ways, then Ctrl-F with “highway -selected” to “invert” that selection. That shows routing islands
@rory
yes, there' s a plugin
maybe this one ?
