The really nice thing about OSM is how easy it is to contribute. There is a famous bicycle route that goes through my town, but it is also famous because it is non-contiguous and completely unmarked on any map. The only way to find it is to ride on the roads and follow the signs (some of which are hand written by residents who live in the area). With OSM it was easy to mark the part of the route that I knew about and now I see a lot of touring cyclists coming through. It's incredibly empowering.
Similarly experience in Philippines in January, Google maps had basically nothing in Palawan but OSM had great coverage.
Other editors can then see the note and might resolve it
OsmAnd is an open source project, however the free OsmAnd version in the Play Store has limitations. You can get the full version (OsmAnd+) if you have money and want to support the developer, but OsmAnd~ has all the features of OsmAnd+.
Well, it’s always funny, but with Google’s data not updated since 2005, they’re pretty useless.
It’s like Google only cares about the US.
I entered a location for the company I worked with. The company moved to another location, so I set about to change the address on Google Maps. To verify I was really the owner of the business, they decided to send mail... to the company's old address (which was occupied by a squatter at the point).
End result, now you have two locations for the company, a correct one and an incorrect one.
I also had a dispute when I edited a location on Antarctica (the Uruguayan base)... editors kept reverting the change.
