OSM worked great for me on newly built streets in Cambridge UK, where Google Maps had zero cartography.
The only major disadvantage of OSM-derived applications is the lack of real-time traffic information. Google Maps harvests data from phones inside cars and some car navigation systems. They also buy it from third parties.
http://opentraffic.io/ http://opentraffic.io/ is trying to do some data harvesting, but it's still not very good. Another option would be to build an aggregator. Lots of governments publish real-time traffic data, so it should be a matter of integrating that into an OSM layer.
Lastly, there's this old technology called Traffic Message Channel which uses RDS (digital data on FM radio) to broadcast traffic warnings. It's quite popular in Western Europe. There's already a F-Droid application that is trying to provide an interface for that: https://f-droid.org/en/packages/com.vonglasow.michael.qz/ https://f-droid.org/en/packages/com.vonglasow.michael.qz/
I cannot stress how important live traffic information is. Without live traffic, navigating on densely populated areas is a nightmare. It's the only part of my mobile workflow I can't do using F-Droid applications. I'm currently forced to use a web version of Google Maps.
- danpat 8y agoHere at Mapbox we're doing navigation on OSM with traffic data - we collect our own telemetry, and use it to guide OSM-based routing. There are numerous Android/iOS apps using our API that you could use, or you could build one yourself.
- em3rgent0rdr 8y agoPlease elaborate. From where and how do you get the traffic data from, and is it sufficient?
- morganherlocker 8y agoOur traffic data is generated in house using anonymized location telemetry from our SDKs, much like most other traffic providers. The live speed predictions we generate for congestion and ETA models are competitive globally, providing the most accurate ETAs available in many parts of the world. Our accuracy today is particularly strong in the US, when compared to similar services.
- arctux 8y agoDo you know if Mapbox has any plans to work with the World Bank's OpenTraffic[0]? [0]: http://opentraffic.io http://opentraffic.io
- morganherlocker 8y agoNot at this time. It's an awesome project, but we started developing our traffic engines around the same time and needs quickly diverged. We do try to open source many of the low level pieces of our model as reusable libraries whenever possible, such as our graph normalization algorithms[1]. At the end of the day, much of the core is difficult to decouple from data engineering infrastructure which will be internal to each organization, due to the immense volumes of live data that must be handled to power a modern traffic engine. Aspects of the model like noise reduction, modality classification, and speed distribution estimation also require lots of fine tuning that is specific to the telemetry being ingested & the usage patterns of the output. For example, our speed models learn and correct from observed errors in various situations over time, which is coupled to our internal metrics data.

- Sir_Cmpwn 8y agoI've been wondering, given that you've made all of the building blocks, why hasn't Mapbox built and released an open source maps app for Android? It looks like you're just weekend's work away from having an open source app which is competetive with Google Maps on F-Droid.
- JetSpiegel 8y agoOsmAnd already exists, and it had a metric ton of development time put into it.
- jakecopp 8y agoI second this, and very interested in doing it myself!
- pymai 8y agoI presumed they open sourced it already since the "Maps" app in the fdroid store is the same app just minus some ads or something
- rmc 8y agoThe "Maps" app in fdroid[1] is actually a recompilation of Maps.me[2], which is from another company, not Mapbox. [1] https://f-droid.org/en/packages/com.github.axet.maps/ https://f-droid.org/en/packages/com.github.axet.maps/ [2] https://maps.me/ https://maps.me/
- mberg 8y agoMapbox has been pretty strategic about not being perceived to compete with it's developers. Besides creating an amazing stack remaining neutral I think is part of their appeal.
- muglug 8y ago> OSM worked great for me on newly built streets in Cambridge UK, where Google Maps had zero cartography. Cambridge is incredibly atypical, though, given its large number of smart people without much money.
- andygates 8y agoNew builds are a target of opportunity for local mappers. There only need to be one or two in a medium city to spot these. It's a much more _fun_ activity than, say, maintaining POIs.
