Yes, connectivity will be a problem in that example. If you make the lines `is_startpoint=false` and they're not connected to something else, then you won't be able to route over them.
You will need to do some pre-processing here - create artificial nodes at the points where the substation boundaries cross the lines and connect both ways to those artificial nodes. daniel On Thu, Aug 24, 2017 at 2:33 PM, François Lacombe <fl.infosrese...@gmail.com > wrote: > > 2017-08-24 23:18 GMT+02:00 Daniel Patterson <dan...@mapbox.com>: > >> Franccois, >> >> In the lua profiles, you can set the `result.is_startpoint` property in >> `process_way` (used to be `way_function`) to determine whether you can snap >> to them.
