As someone who works with mapping data for HGV routing, I've been keeping an eye on Overture. I wonder do you know if anyone has measured the data coverage and quality between this and proprietary datasets like HEREmaps? Does Overture supplement OSM road attributes (such as max height restrictions) where they can find better data from other sources?

I haven't done any deep dives into their road data but there was ~80 GB of it, mostly from TomTom, in the August release. I think the big question would be how much overlap there is with HERE and how would the metadata compare.

TomTom did a few write ups on their contribution, this one is from 2023: https://www.tomtom.com/newsroom/behind-the-map/how-tomtom-ma...

If you have QGIS running, I did a walkthrough using the GeoParquet Downloader Plugin with the 2.75B Building dataset TUM released a few weeks ago. It can take any bounding box you have your workspace centred on and download the latest transport layers for Overture. No need for a custom URL as its one of the default data sources the plugin ships with. https://tech.marksblogg.com/building-footprints-gba.html

		Thanks for the response. There must be value in benchmarking data coverage and quality for routing data such as speed limits, vehicle restrictions, hazardous cargo etc... . I guess the problem is what do you benchmark against.
