> - Google semi monopoly on map data I am sure it varies depending on where you are in the world but in my experience OSM plus official government data is as good as, and sometimes better, than Google. It would be nice to have mine Google Places and Review data but other than that I never feel I am using 2nd rate data when using OSM, in fact I am frequently amazed at the quality and depth of the data. That said, I do…

This depends on what you want to do. If you want to use OSM to find address, then it might be ok. If you want to create directions based on live traffic or find POI/business on map or have street view of location/route, then good luck. Google map have many datasets that just not available or too expensive for competition: - Street view - User upload images of places - Pedestrian and car traffic - Public transport inf…

Public transport information is published and maintained by transit agencies themselves. It’s an open standard and trivially easy to access.

Thanks for the article Dhanraj. I was wondering if you could expand on this part: > Transforming this data into a usable format, such as that required for routing applications, necessitates expensive data pipelines. What do you mean by "usable" here? I've worked with OSM data in .osm and .pbf formats for routing applications; there are a few things to look out for (e.g. badly formatted tags), and the ways/nodes graph…

You are correct about ingesting the osm data directly to something like Valhalla. What had in my mind when I mentioned "usable" is the data after that will be the output of some sort of quality control process. As you said, osm data will have quality control issues (being a crowd sourced) and organisations will want quality checked before the data is fed to their internal systems including inserting to database or to…

Cheers for the reply. By "quality control process" do you mean manually checking bridge height restrictions, recent road closures etc..., or do you mean something more automated such as filtering out badly formatted data?

its mix of both. I don't think full automation is possible at the moment.
