#Biking : So far I've mainly used #Brouter.de as #RoutingEngine to #plan the safest possible #cycling #tours and was very happy with it. Now I'm discovering #Valhalla and I'm simply amazed at how adjustable it is and how incredibly good the #results are for my specific #needs .Any #thoughts and #experiences about how these two #routing #engines compare?

Our own @ianthetechie is working on an awesome map for the "lines" .

Want to know what the routing engine sees according to data? Well, now you can.

The map is color coded by road classification: brighter green lines show major highways (motorways), orange are arterial roads, and the darker reds are local roads.

And what could those lines in sea be? Ferries! 🛳️

We're looking forward to seeing what everyone creates during this fun annual challenge.

I was helping an #UrbanPlanning friend with some spatial analysis with #QGIS but the project seemed to be running out of her 8GB memory.

I advised a #FrameworkLaptop with more memory. She got the DIY option, which lead her to consider her OS choice, which lead her try #Linux (#Ubuntu), which is what she installed after testing it.

Now we'll get back on track using #QGIS / #Docker / #Valhalla / #TurfJS to explore some spatial analysis ideas.

Hey #OpenStreetMap peeps, how can I debug this strange routing behavior?

#GraphHopper & #OSRM make a simple left turn (correct), while #Valhalla and #OsmAnd act as if there's a turn restriction and make a U-turn instead.

This is at 51.73201° N, 9.97389° E, coming from north on B3 and going to the east on A7.

There's been a construction site here a few weeks ago, so my first suspicion was stale data, but even with OsmAnd Live it still does it.

I can't see any restrictions in the data. Ideas?

Continued thread

I've now published a write-up and the source code for how I calculated a connectivity rank which could be used to help prioritize how a bike network is built out based how segments would improve connections with the existing network.

Thanks to all the open source mapping projects that helped make this possible, including #qgis #valhalla #josm and #turfjs. And yes, I used JavaScript for this.

Feedback, improvements welcome!
