| 1. This is largely country-dependent with some governments being quite adamant that address data should be in the public domain, and some governments doing the opposite and selling address databases to private companies for some quick cash, where private companies then sell address lookups for some absurd per-lookup price for the next few decades. Most of the world though is probably just not rich enough to compile, publish and accurately maintain a national address database. OpenAddresses is perhaps the gold standard for open source address data compilation from government datasets. Note for the future that alltheplaces.xyz (project I contribute to) is looking like it may eventually perform the automatic address data download/extraction/compilation that OpenAddresses currently performs. This has the benefit that in backwards countries, alltheplaces.xyz also obtains some addresses through other means--such as advertised location of international restaurant chains. And quite often, being within +/- 100 address numbers on a road is good enough for navigation. Google Maps obviously crawls addresses from all over the Internet AND has quite a high tolerance for errors, hence will perhaps always seem more complete than OSM. 2. Some further ideas for open source mapping applications trying to determine real time traffic situations: 2a. Use GTFS/GTFS-RT feeds for bus networks to detect real time delays but also to compare planned bus route schedules for different times of the day (different traffic conditions) where buses share the road with the public. There's already a few maps out there that overlay nearby GTFS-RT feeds for the city of interest and usefully provide a visual indication of how well public transport vehicles are currently moving. 2b. alltheplaces.xyz extracts public traffic camera feeds which could be presented to users when they plan/commence a journey as an indication of what lies ahead on the route. |

| Agree! CoMaps fork is adding OpenAddresses integration and traffic (linked above)! https://codeberg.org/comaps/comaps/pulls/4162 |

| While default osm data is great, I've been very impressed with the partnership/collective of Overture Maps data. It's osm + esri/tomtom + corporate processing/funding. https://overturemaps.org/ While not updated as frequently, their releases have a pretty high quality and coverage. |

| Also current place names. You can sometimes find a business on OSM that has correct metadata, but in many areas the majority are missing or stale (like, closed 10+ years ago.) Solving this is an "interesting" problem to say the least when many businesses these days have nothing more than an Instagram/Whatsapp handle. |

| There's one more for me: reliable store hours. |

| ▲ | dhx 2 hours ago | parent | next [-] | | See alltheplaces.xyz for continuously updated straight-from-the-primary-source opening hours of chains of shops and restaurants, public facilities such as libraries, etc. This is probably as accurate as it gets AND you have the confidence of knowing exactly where the data came from (down to the URL) and when it was last checked. Some OSM contributors go brand-by-brand/operator-by-operator in making sure OSM features have the most up-to-date opening hours added to them from matched ATP features. As such, OSM may be fairly accurate for chains too. For a standalone shop or restaurant the opening hours situation is usually still better with Google Maps rather than OSM. There aren't enough OSM contributors who care enough to check and maintain opening hours for every shop, restaurant, fuel station, etc. | |

Google has the benefit of having their own street-level imagery for house numbers and street names, Android devices for real-time traffic info, and the ability to simply scrape web pages for shop data including opening hours. but in places with a reasonable number of active mappers, OSM is so much richer and more up to date. | | | |
| ▲ | eisa01 3 hours ago | parent | prev [-] | | Agree, which is why I added support for displaying when the hours were last updated in CoMaps Organic Maps didn’t accept my PR with it… https://codeberg.org/comaps/comaps/issues/688 |

| Yeah (2) is the killer feature especially in totalitarian shitholes (pretty much every country nowadays) full of money grab ops disguised as police checkpoints and cameras. I wonder if we can build a decentralized version of such a reporting service. |
