Improve OSM Improved - and now with Turn Restrictions about 1 month ago

What do the numbers presented on the detected turn restrictions mean?

Damn...already knew them...

UK NCN 44 rerouted about 2 months ago

Heh, please share your experience with the mailing lists. I'm trying to get route=road to stick and one of the biggest arguments is that relations are a pain in id.

exit_to vs destination Update (USA) about 2 months ago

Destination definitely has the advantage of being applicable to more situations than just freeway exits, being more specific (a real issue given about 20-30% of ramps in my region are something other than off to the right, and I'm aware of some truly convoluted ramps that barely grasp real world logic much less are something that can be readily assumed by data consumers from a single point), and already has live adoption (Osmand at the very least).

Street names in Brazil are doomed 3 months ago

You should bring the changesets to the attention of the DWG

Proposal: Sunset ref=* on ways in favor of relations 3 months ago

@robert: If id is unable to handle relations in a rational manner, given that relations are a basic data type alongside ways and nodes, that's a major deficiency in id and should be pointed out to the devs.

Proposal: Sunset ref=* on ways in favor of relations 3 months ago

@Sanderd17: That's not true at all, or the cycleway and walking networks would have the same refs as the motoring network. It took me all of 15 seconds and zero effort just zooming in on a random location and finding a duplexed ref (in this case, road A27 and RCN CS7 in London).

Mapping Freeway Exits, Powered By Road Geeks With Cameras 3 months ago

I'd throw junction:ref on the same way as the destination=* tag. I realize in theory it's rare to need that level of disambiguation but in practice, there's enough mutually split (such as the end of a long ramp where a "C,D,E" of a multi-ramp exit split), left, or some central lane (still can't believe Oregon actually made lanes 1,2 and 4 the through lanes, and lane 3 an exit only lane where OR 8 splits from US 26 westbound; that one being the weirdest of the "not leftmost/rightmost-lane exit" situations I've seen).

Proposal: Sunset ref=* on ways in favor of relations 3 months ago

Especially since many of these routes are already multiplexed with the only difference being the mode of travel.

Proposal: Sunset ref=* on ways in favor of relations 3 months ago

So what makes motorists somehow privileged as a mode to do it differently than we already handle foot, bus, bicycle, and literally every other kind of route?

New MapRoulette challenge idea: exit_to > destination 3 months ago

I'm pretty much convinced we need it because of the offside exit problem and navigation. However, for rendering purposes, motorway_junction's still going to be necessary.

How to find Missing Roads in OSM with GPS data 4 months ago

I would encourage users mapping against this to MAP the dirt tracks and what not that are getting traffic detected, since it is an indication that people are able to traverse it, rather than marking those as invalid.

New MapRoulette challenge idea: exit_to > destination 5 months ago

junction:ref=* as well! As you previously pointed out, it does obviate which direction the exit leaves the trunk or motorway!

Simulate traffic using OpenStreetMap-data and SUMO- Simulation for Urban MObility. 5 months ago

OK, this is a total pisser from a Debian perspective...can't seem to get traffic generated.

New road style for the Default map style, the full version - PR, casings on z11 6 months ago

Damnit, Australia, get on board with specifics! National Highways should be AU xxx and state highways should be the postal abbreviation and XXX (NSW 391 or WA 47 as possible examples).

Complex Intersections, or Why We Should Get Rid Of exit_to 6 months ago

OK, it's been a bit of work using it for tagging, but some things I've noticed:

  • destination and destination:lanes is far less ungainly than a simple exit_to or relations
  • I'm not convinced Osmand uses this data yet. It certainly would be handy to validate things, since I'm currently working to implement this state wide as part of my lanes and relations completion project.
Mapping turn lanes in OpensStreetMap 6 months ago

The turn lanes plugin should not be used at this point, as it uses the scheme that Has Lost The Warâ„¢. turn:lanes is the way to go, it's the one that has consumer and rendering usage at this point, and the easier option to wrap your head around.

Restoring measurements from crashed database of Tower Collector 6 months ago

I would hope you're also contributing this data to radiocells.org (especially if there's any wifi data inclusive).

It's too damn high 6 months ago

So, am I to surmise, based on Bubble's presence in this thread, that something's fucky?

Addresses in Oklahoma 9 months ago

This seems to be a common thing with local US governments. The data is open, but often citing some really thin vineer of excuses to charge for access to the data directly from them. The primary audience tends to be realtors and land developers who generally don't give a shit about spending the $50 to get the current official dataset.
