Hi Gerd I was thinking of a threshold (maybe < 5) and then not adding any of them to NOD. The reason is that a while ago I found many instances where tracks lead up to the edge of car-parks but didn't join to each other or the car -park access road and so walking routing, where one was expected to cross the car-park, didn't work. I tried adding a footway around the edge of the car-park and this helped in a lot of cases but I got driving route-calculation-error in or out of the car-park if the access road wasn't correctly specified. Your latest change will help in a lot of instances but sometimes there car-park was defined by more than 1 line. Ticker On Sat, 2019-10-12 at 10:10 -0700, Gerd Petermann wrote:

Do you attempt to isolate small road networks that are not connected to the rest of the system or just a single road?
Not yet. Do you think about some kind of threshold value giving the minimal number of connections or maybe a bbox size or a sum of road lengths? if the isolated network is "small" we might not add any of its roads to NOD. Is that what you think about?
