This is really cool. Can I suggest for the Twin Cities metro area someone doing something similar with the Metro Regional Centerlines Collaborative Local Centerlines (MRCC)? I know that Dakota County hasn’t submitted centerlines to Tiger in a couple of years, but will be for the next update. Not sure about the other counties though. There very well may be areas that the MRCC will be a better source than the Tiger data.

It would be interesting to see what differences CYGNUS would turn up. What would the output of CYGNUS be? I put together the TIGER 2017 layer that's in the editors right now. I'll work on writing up how I did it later today. Basically: I used tiger-tiles (https://github.com/iandees/tiger-tiles) to generate a vector tiles database with expanded road names from TIGER 2017. Then I downloaded an osm-qa-tiles (https://osmlab.github.io/osm-qa-tiles/) file for the United States and ran osmlint's tigerDelta (https://github.com/osmlab/osmlint/tree/master/validators/tigerDelta) to find the segments that had different geometry. The output was then ran through Tippecanoe to generate a vector tileset and posted to Mapbox as the low zoom red features.

This would be something useful for the community ? I don`t know if somebody is already doing something similar, or what is the status ? Were can i read more ? I knoiw that the TIGER 2017 Overlay in JOSM shows in red the roads that are not in OSM, but are in TIger 2017. But I don`t know were to read more, and if the data is accessible to download directly, not just show as a WMS Layer. It will take around 7-14 days to process all USA” _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-us
