[OSRM-talk] Use OSRM on rivers, railways, power lines

[Daniel Patterson]

Hi Francois,

  In theory, yes, you could route on powerlines, gas lines, or any other
linear feature.  Ensuring connectivity could be problematic - often rivers
are not connected to paths in OSM.

  Waterways are a bit problematic as they're often modeled as areas - if
you modify the Lua script to include them in the routing graph, OSRM will
route around the edges of the polygon.

  Getting proper connectivity between all the elements you want to route
between can be problematic as well - very often, rivers/rail are not
connected to roads or paths inside OSM.

  The turn-by-turn instructions might also be a bit weird if you don't
route on roads/paths - the guidance code has been mostly focused on
sensible instructions for drivers.
