OpenStreetMap 開放街圖
I spent some time on Monday evening adding lots of buildings in Winwick Quay and Gemini Business Park.
I also added various footpaths from around Great Sankey, and it got me thinking as to exactly where it's appropriate to add a footpath. In most villages/towns/cities, it's virtually a given that a road is accompanied by pavements at either side, so it's almost meaningless to add these footpaths.
But in a lot of new developments these days, it seems more and more fashionable to omit them. Certainly where I live, in Great Sankey Warrington, my estate forms part of what used to be the old Burtonwood Airforce base which is slowly being converted into new housing. A great deal of the new road system, mainly primary roads, simply don't have paths at the side. But shared footways/cycleways have been constructed, so it seems that they are significant and should be shown prominently on the map.
The confusion comes in the areas where cycle/footpaths converge onto a road, on both sides, creating a "grey area", and subsequent doubt. Just wondered what other people's thoughts are?

I've been wondering about this too. When I walked around a couple of local roads to check out their addresses the GPS tracks clearly showed up both footpaths at the side of the road, including where the path meandered away from the road briefly. It is a lot of work to cover a large village, never mind a town or city.

I wondered about this also to begin with. However, I reasoned that since paths are typically parallel to roads that they don't make for much of a navigational feature. I do add them where the path diverges from the road curb by more than a few metres though and where paths intersect roads at sharper angles. If you try adding paths beside roads as well as being a lot of effort it's likely that the close proximity means they won't render well either.

I add seperate ways when there is a clear border between. At crossings/joints I simply "cheat" and connect the footway to the road, then go away from it again. That makes routing work and is not visible on the maps most of the time.

the rule I follow is that if the path is right next to the road, then I dont add it, but if theres a grass verg or path takes a route away from the road I add it in. Elgin place coatbridge shows this well
