Streetlamp mapping does not help. All our city cycleways are within the lighting radius of street lamps, but
- they are often interspersed with street-linign trees. - lamps may be on the opposite side of the street than the cyclepath - street lamps have illumination bodies pointing at strange angles - some street lamps are not strong enough - cycle ways are separated from streets by guard rails that throw a dark shadow excactly on the cycle way (in more than one place) This is admittedly the most bizarre of the problems So if I go ahead with a smoothness-like approach, is it better to use lit=no|yes|poor|sufficient|good or lit=yes lit:level=poor|sufficient|good Thanks Volker On 18 January 2015 at 16:20, Martin Koppenhoefer <dieterdre...@gmail.com> wrote: > > > > > > Am 18.01.2015 um 12:16 schrieb Volker Schmidt <vosc...@gmail.com>: > > > > Assume you have a 100m stretch with nice illumination but there is a > tiny S-bend exactly overshadowed by an evergreen tree, which produces a > pitch dark spot of 10m at a dangerous point.
