Hi,<br>
i found some changesets downgrading streets to unclassified. After some<br>
discussions the mapper were under the impression that unclassified is<br>
something higher priority than residential.<br>
<br>
>From my long tagging practice in OSM unclassified and residential are<br>
identical in respect to priority. (And e.g. OSRM treats them equal) <br>
The first is used as a connecting road off city limits. The latter is<br>
used for the lowest class roads within city boundarys (Where there is<br>
residential usage)<br>
<br>
So for me retagging residential to unclassified is broken under the<br>
assumption that unclassified is something "better" than residential.<br>
<br>
It is even more broken when there is residential usage in which case<br>
unclassified is inappropriate.<br>
<br>
While discussing i found that there was some modification to the German<br>
version of unclassified not saying that unclassified is something<br>
"better" but suggesting that an unclassified should be dragged into<br>
city limits until the next higher class street. This lets user<br>
assume that unclassified is some higher priority than residential.<br>
<br>
<br>
I was treating those streets identical for the last 10+ years and only<br>
the city limits gave the indication whether to use unclassified or<br>
residential.<br>
<br>
Am i wrong with that usage?<br>
<br>
Flo<br>
