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

If it is OSM data issue then you can ask for help on one of https://wiki.openstreetmap.org/wiki/Contact_channels

Or me directly - though either would likely require revealing your address and location to diagnose what is going wrong.

Have you tried fixing the map yourself? It's easy, just like Wikipedia.

As an OSM mapper I would not say that debugging and fixing address issue is easy...

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…

These experiences are interesting, but I think Annapurna might not be the right benchmark to evaluate against. One of the least climbed and most deadly mountains on Earth seems rather far from OSM's core use case. It is cool that OSM has the data, but I hope anyone attempting the summit is getting information more directly from other climbers.

The reference is presumably to hiking the Annapurna Circuit, not for climbing Annapurna itself.

Earlier quoted context omitted.

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.

I'm often hesitant about mapping the unofficial trails, particularly the ones you aren't supposed to use. There are many around the SF bay area, some are simply non-maintained non-system trails, while others are illegal mtb paths off the allowed trail network. Some of them are so well traveled in areas with minimal erosion that they are almost as good as maintained trails, although often less well graded.

Yeah, these are basically ATV trails near my property which are probably mostly not supposed to be there. Certainly on private land although conservation land as well. I've been appreciative for them during current times and I've even been appreciative that the ATVers tend to come in and clear fallen trees and the like. But that doesn't mean I feel comfortable plotting tracks on OSM--especially those parts of the tracks on private land and especially those parts where ATVs have ripped up the terrain in said private land.

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)

someone was kind enough to upload their recent (oct 2020) build of OSM vector tiles to the internet archive: https://archive.org/details/osm-vector-mbtiles

This is good to hear. Any idea if it's accurate with coastal data? I'm asking for a scientific project that seeks to map the locations of various seaweed strains.

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…

Other than the ones that have been mentioned already, I also use Maverick, which has a free and a paid version.

I like its ability to show the different map layers, and it has great information screens that show things like GPS coordinates and such, great for geohashing or geocaching. Also has a cool display of how many satellites are visible and whether they're GPS or GLONASS or whatever.

The track recording feature is also nice, saving as a gpx file that can be easily uploaded to the openstreetmap online iD editor with drag-and-drop.

I often notice when OSM is wrong/missing data while hiking and I'll record a trace and update when I get back home. I enjoy contributing but I wish there was a bit more of a community aspect to it (or maybe I simply haven't found that). In some areas the US government agency maps are hilariously out of date or simply completely wrong so OSM is great to able to simply fix it after visiting.

I've really enjoyed the community at slack.openstreetmap.us great for finding projects or people to work with. There are local channels!

Lyft has access to some pretty good data on where the roads actually are and if there are any closures. Looks like they are already contributing back, which is awesome. Something I've never heard being done, but could be very helpful for cities, is tracking the bumpiness of roads as a metric for road quality. The city could have near real time access to information on where the potholes are. I'd think they'd be willi…

The wiki states that this data type is being proposed: https://wiki.openstreetmap.org/wiki/Proposed_features/Surfac...
