Re: [OSM-talk] Roundabouts - why is a separate segment required?

2018-02-14 Thread Matej Lieskovský
If two ways enter a roundabout at the same point, you can turn from road A into road B instantly, but going from B to A will require going around the entire roundabout. For a router to detect this, it would have to check (for every encountered node): 1) is this a part of a roundabout? 2) if yes, wh

Greetings! I saw a nice argument somewhere about the lines for larger rivers that might be applicable here: Imagine if the water level dropped significantly - the areas would be off (but should be kept at their normal level unless the change is likely to be reasonably permanent) but the lines shou

I'd like to reiterate that (much like riverbanks) the shoreline of a lake can change far faster than the river channel. While the area maps the "usual" extent (ignoring droughts and floods), the line is a very useful abstraction. Not connecting rivers into a network invalidates the idea of a netwo

A "traffic" tag sounds like a good idea, but I'd have two suggestions: 1) Can we find a better name? 2) Estimates are better than words. I can imagine what 5000 cars per day look like, but what is considered heavy traffic in (for example) Brazil? I'm all for letting highway tag only worry about hi

1) If you want to look at a professional map of Czechia, I'd recommend www.mapy.cz over google maps as that is the most used and far more detailed map. 2) I agree that the discontinuities are ugly, but they reflect the state on the ground. That section around Sulec is a trunk instead of a primary d

One last observation: Austria, Czech Republic, Denmark, Germany, Netherlands, Poland and Slovakia all use a similar system where highway=trunk is "motorway-like", with trunk either implying motorroad status, or being a prerequisite for it. On 24 February 2018 at 11:08, Matej Lieskov

Maybe we could use OAuth only to link the accounts - wiki user X is (proven by OAuth) to be OSM contributor Y. Inelegant, but it would make it simpler to identify the active mappers among the wiki accounts. Obviously an opt-in system. On 19 March 2018 at 08:25, Andrew Hain wrote: > You could say
