"Road directionality" being only 98.9% accurate seems to be a huge problem for a navigation app!

Im yet to read TFA, but I could foresee there being plenty of one-way private drives and parking lots - if not included in the study, I tend to agree with you

Now if only there was a sensible way to self-host OSM data. From what I've found you either have to build a dedicated server to continuously building the tiles (which takes a ton of storage and processing power) or pay for it at an insane monthly price. I wish OSM would directly make their tiles available to mirror. (Maybe they do, but I haven't found it yet)

https://hub.docker.com/r/maptiler/tileserver-gl

hosing the entire planet is not sensible, but you can safely host a region/city/small country.

that said im not in love with maptiler and trying out a bunch of other tile servers with limited sucess.

What is the best-in-class iOS app using OpenStreetMap? For iPhone, MagicEarth looks extremely good ( https://www.magicearth.com/ ), but I'm wondering if people have other recommendations...

Arguably, “Windy Maps” is up there:

https://apps.apple.com/us/app/windy-maps/id1201228182

Same devs as the stunning https://www.windy.com/ weather site which also has an app:

If you're more about hiking, maybe “Gaia GPS Hiking, Offroad Maps”:

Except my street. No matter how many times I email Lyft support, it always sends them the wrong place. Most Lyft drivers don't read the directions on pickup either explaining the problem. /sigh #FirstWorldProblems

No bothersome problem is too small! If you'd like to share, we would be eager to look into this. Reach us through the app or at osm-questions [a] lyft.com.

The real problem of GP is with the drivers not reading the note. Each system should have a manual override, Lyft does seem to have one, but the human element failed.

Good that OSM is accurate in cities as well, because in hiking, skiing, or even some ferry routes, OSM simply wins because that's often the only mapping provider to even have _any_ data. Some of my first hand experiences: - French GR-20 routes. Google maps are laughably empty, while OSM has you covered with almost the same information as the hiking maps you can buy on the trail. - Anapurna - similar to GR-20 situatio…

OSM isn't perfect--especially on trails that aren't official in any way. (Although there are some totally informal trails literally out my door that are far better than you could reasonably expect. And the missing sections are probably on private land which is one reason I haven't filled them in.) But Google seems to have pretty much zero interest in mapping even popular official trails in many cases.

Help contribute back to make it amazing. That's why OSM is amazing :)

I've been looking to replace Google Maps with OSM on my smartphone. OSM itself is great, but I've been having a harder time finding a good app to use it with. Is anyone familiar with a good option? I mostly use a maps app for location searches and real-time GPS navigation, but offline maps and location sharing are nice-to-have features. I've been using OsmAnd and it's okay. The interface is pretty good. It supports o…

I'm pretty sure OsmAnd renders all the roads, buildings etc on demand, which is why it's slow. It has to be able to rerender since it supports different styles, but it doesn't seem like it caches the results or prerenders adjacent tiles.

EDIT: performance issues seem to not be due to rendering the vector data[1].

I usually look at Strava's heatmap when I'm unfamiliar with an area. Chances are if there's a path on the map, it shows up on the heatmap. https://www.strava.com/heatmap

That is a fantastic idea. Thank you for sharing. I just checked a few trails that were missing in OSM and they all showed up as bright yellow on heatmap.

Strava even has their own fork of the OSM online editor iD[0], that uses the heatmap data to align (or "slide" [1]) paths to where people have been. I haven't used it in a while, it was pretty slow when I did and I don't know about licensing etc, but it looks like it still works. So if you want to add the trails you could try it out.

I like Locus maps a lot. The UI is a little busy but once you get used to it you appreciate it because it really is a work of love.

It gave my old Garmin GPS a new life, where Garmin stopped providing updated data. A packaged map file with OSM data made it useful again.

For those in a similar situation, I use this

Road directionality is variable over time. I'm not sure at what rate it changes but I bet it's a lot more than 1.1% per year.

Hmm, I’ve seen maybe a handful of two-way streets change to one-way over my entire life, and have never seen a one-way street change direction. If ~1% of streets changed direction every year, there’d be mass confusion and frustration.

Mapping OSM in NYC, I've run into about a dozen one-way streets that have changed direction at some point, sometimes for just a block or two.
