[OSRM-talk] Non-routing places

[Dennis Luxen]

John,

thanks for flagging this. We are working on a better/automatic solution right now. In the mean-time you can avoid so-called ‚small‘ components of the road network by adding a low zoom level to the query, e.g. &z=12. With this setting, it will ignore unconnected portions of the road network. Or add a high zoom level, e.g. &z14 to chose the nearest piece of road ignoring if it is connected or not.

The nearest call is pretty much unrelated to routing and not necessary at all when requesting a route, although it respects the zoom level parameter as well.
